How does blood flow through the heart and lungs step by step?
Blood comes into the right atrium from the body, moves into the right ventricle and is pushed into the pulmonary arteries in the lungs. After picking up oxygen, the blood travels back to the heart through the pulmonary veins into the left atrium, to the left ventricle and out to the body's tissues through the aorta.
How does blood flow through the lungs?
When the heart beats, the ventricle pushes blood through the pulmonic valve into the pulmonary artery. The pulmonary artery carries blood to the lungs where it “picks up” oxygen. It then leaves the lungs to return to the heart through the pulmonary vein.
What are the 7 steps of blood flow?
Blood flows through the heart in the following order: 1) body –> 2) inferior/superior vena cava –> 3) right atrium –> 4) tricuspid valve –> 5) right ventricle –> 6) pulmonary arteries –> 7) lungs –> 8) pulmonary veins –> 9) left atrium –> 10) mitral or bicuspid valve –> 11) left ventricle –> 12) aortic valve –> 13) ...
What is the correct order of blood flow from the heart to the lungs and back to the heart?
As the ventricle contracts, blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs, where it is oxygenated. The oxygenated blood then returns to the heart through the pulmonary veins.
What is the correct order of blood flow from the heart to the lungs in the fetal circulatory system quizlet?
From Brain: ->superior vena cava-> right atrium-> right ventricle-> pulmonary artory-> 10% to lungs->remaining to ductus arterious -> aorta-> umbilical arteries->placenta.
How does the circulatory system work step by step?
The circulatory system (cardiovascular system) pumps blood from the heart to the lungs to get oxygen. The heart then sends oxygenated blood through arteries to the rest of the body. The veins carry oxygen-poor blood back to the heart to start the circulation process over.
What is the correct blood flow order?
The right ventricle pumps the oxygen-poor blood to the lungs through the pulmonary valve. The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle through the mitral valve. The left ventricle pumps the oxygen-rich blood through the aortic valve out to the rest of the body.
What is the correct order for the flow of blood entering?
From lungs, oxygenated blood enters left atrium to go to left ventricle to be carried by aorta to whole body. So, the correct answer is 'Right atrium→ right ventricle → left atrium → left ventricle'
How do you remember the order of blood flow?
Many people get confused on if the blood enters the tricuspid or bicuspid valve first. Remember this saying, “First always try, before you buy”. By remembering this phrase, you will remember that the tricuspid (try) is before the bicuspid (buy) valve.
How does blood flow through your lungs?
Once blood travels through the pulmonic valve, it enters your lungs. This is called the pulmonary circulation. From your pulmonic valve, blood travels to the pulmonary artery to tiny capillary vessels in the lungs. Here, oxygen travels from the tiny air sacs in the lungs, through the walls of the capillaries, into the blood. At the same time, carbon dioxide, a waste product of metabolism, passes from the blood into the air sacs. Carbon dioxide leaves the body when you exhale. Once the blood is purified and oxygenated, it travels back to the left atrium through the pulmonary veins.
How does blood flow through the right ventricle?
Blood flows from your right atrium into your right ventricle through the open tricuspid valve. When the ventricles are full, the tricuspid valve shuts. This prevents blood from flowing backward into the atria while the ventricles contract (squeeze).
Where does blood travel through the pulmonary artery?
Once blood travels through the pulmonic valve, it enters your lungs. This is called the pulmonary circulation. From your pulmonic valve, blood travels to the pulmonary artery to tiny capillary vessels in the lungs. Here, oxygen travels from the tiny air sacs in the lungs , through the walls of the capillaries, into the blood.
Which vein empties oxygen rich blood from the lungs into the left atrium?
The pulmonary vein empties oxygen-rich blood, from the lungs into the left atrium.
Where does oxygen travel?
Here, oxygen travels from the tiny air sacs in the lungs, through the walls of the capillaries, into the blood. At the same time, carbon dioxide, a waste product of metabolism, passes from the blood into the air sacs. Carbon dioxide leaves the body when you exhale.
Which side of the heart works together?
The right and left sides of the heart work together
Which side of the heart is the blood entering?
Right Side. Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium.
How Does Blood Flow Through the Heart?
It is responsible for pumping blood as well as nutrients to the different organs of your body. It pumps the blood to your lungs from where oxygen is transferred into it after your body has used it. This process is known as ‘oxygenation.’
What is the AV node?
A group of cells lying in your heart’s center between your ventricles and atria known as the atrioventricular (AV) node works like a door that reduces the speed of the electrical impulse before it moves to the ventricles. This slight delay gives your atria enough time to quickly contract prior to the contraction of the ventricles.
How does systemic circulation work?
Systemic circulation refers to the blood’s movement from your heart throughout the body to supply nutrients and oxygen to the body parts and bringing back the deoxygenated blood to your heart. Blood rich in oxygen leaves your lungs and enters your left atrium via the pulmonary veins. It is pumped to your left ventricle via your mitral valve. It then moves to the aorta via the aortic valve. Your aorta branches and splits into different arteries moving to your upper body and then passes through your diaphragm where these arteries further split into smaller arteries that supply oxygen saturated blood to your body’s lower parts. The arteries divide into many smaller arteries and arterioles and eventually turn into capillaries. Carbon dioxide and waste diffuse into your blood from the cells whereas the oxygen and nutrients in the blood move out of the blood to the cells. The oxygen depleted blood moves through your capillaries that merge together to form venules and then large veins. Eventually, the veins come together to form the big venae cavae that drains into your right atrium. The deoxygenated blood will then continue its pulmonary circulation to become rich with oxygen.
What is the name of the valve that moves blood to the ventricles?
There are two atrioventricular (AV) valves ascertain that the blood moves to the ventricles from your atria only. The valve on your heart’s right side in known as the ‘tricuspid’ valve and the valve on the heart’s left side is known as the ‘bicuspid’ or ‘mitral’ valve.
What is the process of blood flow?
This process is known as ‘oxygenation.’. Your blood flows via the heart in two individual loops. They are known as the right and left side loops. The left side of your heart is your left side and the right one is your right side. The right side gathers the deoxygenated blood coming from your body. It pumps it to your lungs where ...
What is the SL valve?
The SL valve on your heart’s right is known as the ‘pulmonary’ valve as it connects to your pulmonary arteries. The SL valve on your heart’s left side is known as ‘aortic’ valve as it connects to your aorta.
Which veins pump blood to the heart?
Pulmonary veins pump the fresh oxygenated blood once more to your heart and right in its left atrium. The blood is then transferred to your left ventricle that pumps it to your aorta that transfers the blood to the different body parts. Both the ventricles are stronger and thicker than the atria.
Pathway of Blood Through the Heart
In this educational lesson, we learn about the blood flow order through the human heart in 14 easy steps, from the superior and inferior vena cava to the atria and ventricles.

What The Heart And Circulatory System Do
The circulatory system works closely with other systems in our bodies. It supplies oxygen and nutrients to our bodies by working with the respiratory system. At the same time, the circulatory system helps carry waste and carbon dioxide out of the body.
What Heart Rate Is Too High
Going beyond your maximum heart rate is not healthy for you. Your maximum heart rate depends on your age. This is how you can calculate it:
What Are The Coronary Arteries
Like all organs, your heart is made of tissue that requires a supply of oxygen and nutrients. Although its chambers are full of blood, the heart receives no nourishment from this blood. The heart receives its own supply of blood from a network of arteries, called the coronary arteries.
Easy Way To Remember Blood Flow Through The Heart
The blood flow of the heart is something you will have to learn in nursing school . When I was in nursing school I hated learning about the heart and promised myself that I would never enter into cardiology. Well, to make a long story short, I entered into cardiology and have never left it. I learned to heart the heart.
The Heart Is A Muscle
Your heart is really a muscle. It’s located a little to the left of the middle of your chest, and it’s about the size of your fist. There are lots of muscles all over your body in your arms, in your legs, in your back, even in your behind.
Flow Chart Of Heart Blood Flow

How The Heart Beats
How does the heart beat? Before each beat, your heart fills with blood. Then its muscle contracts to squirt the blood along. When the heart contracts, it squeezes try squeezing your hand into a fist. That’s sort of like what your heart does so it can squirt out the blood. Your heart does this all day and all night, all the time.
What is the function of the pulmonary circulatory system?
Function: Pulmonary Circulaton brings blood into contact with alveoli in the lungs for gas exchange (this is the only place in body where arteries carry O2 poor blood and veins carry the O2 rich blood). The atria of the heart are separated from the ventricles by doorways called valves.
Which part of the body is responsible for pumping oxygen to the lungs?
Blood circles through the heart, which pumps it to the lungs where it picks up oxygen - this is the pulmonary circulation. The heart then pumps the oxygen-rich blood to the rest of the body - this is the systemic circulation.
Why are valves important?
Valves are important because they keep the blood flowing forward. The circulation of the blood through the heart starts when blood comes back to the heart through two big veins called the vena cava. > The blood then flows into the right atrium. > Then it passes through the tricuspid (3-cupped) valve into the right ventricle.
When you research information, do you cite the reference?
When you research information you must cite the reference. Citing for websites is different from citing from books, magazines and periodicals. The style of citing shown here is from the MLA Style Citations (Modern Language Association).
What happens when a baby's blood pressure increases?
An increase in the baby's blood pressure and a significant reduction in the pulmonary pressures reduces the need for the ductus arteriosus to shunt blood. These changes promote the closure of the shunt. These changes increase the pressure in the left atrium of the heart, which decrease the pressure in the right atrium.
What happens to the lungs after birth?
With the first breaths of life, the lungs begin to expand. As the lungs expand, the alveoli in the lungs are cleared of fluid. An increase in the baby's blood pressure and a significant reduction in the pulmonary pressures reduces the need for the ductus arteriosus to shunt blood. These changes promote the closure of the shunt. These changes increase the pressure in the left atrium of the heart, which decrease the pressure in the right atrium. The shift in pressure stimulates the foramen ovale to close.
What part of the fetus does the blood flow to?
In the fetus, the placenta does the work of breathing instead of the lungs. As a result, only a small amount of the blood continues on to the lungs. Most of this blood is bypassed or shunted away from the lungs through the ductus arteriosus to the aorta. Most of the circulation to the lower body is supplied by blood passing through the ductus arteriosus.
How does blood enter the heart?
Inside the fetal heart: 1 Blood enters the right atrium, the chamber on the upper right side of the heart. When the blood enters the right atrium, most of it flows through the foramen ovale into the left atrium. 2 Blood then passes into the left ventricle (lower chamber of the heart) and then to the aorta, (the large artery coming from the heart). 3 From the aorta, blood is sent to the heart muscle itself in addition to the brain. After circulating there, the blood returns to the right atrium of the heart through the superior vena cava. About two thirds of the blood will pass through the foramen ovale as described above, but the remaining one third will pass into the right ventricle, toward the lungs. 4 In the fetus, the placenta does the work of breathing instead of the lungs. As a result, only a small amount of the blood continues on to the lungs. Most of this blood is bypassed or shunted away from the lungs through the ductus arteriosus to the aorta. Most of the circulation to the lower body is supplied by blood passing through the ductus arteriosus. 5 This blood then enters the umbilical arteries and flows into the placenta. In the placenta, carbon dioxide and waste products are released into the mother's circulatory system, and oxygen and nutrients from the mother's blood are released into the fetus' blood.
What is the purpose of shunts?
The purpose of these shunts is to bypass certain body parts ? in particular, the lungs and liver ? that are not fully developed while the fetus is still in the womb. The shunts that bypass the lungs are called the foramen ovale, which moves blood from the right atrium of the heart to the left atrium, and the ductus arteriosus, ...
How does the fetal circulatory system work?
The fetal circulatory system uses two right to left shunts, which are small passages that direct blood that needs to be oxygenated.
What is the umbilical cord?
The fetus is connected by the umbilical cord to the placenta, the organ that develops and implants in the mother's uterus during pregnancy. Through the blood vessels in the umbilical cord, the fetus receives all the necessary nutrition, oxygen, and life support from the mother through the placenta. Waste products and carbon dioxide from ...
