What are the 14 steps of blood flow?
in summary from the video, in 14 steps, 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 …
What are the steps of blood flow through the heart?
Right Side of the Heart
- The un-oxygenated blood (this is blood that has been “used up” by your body and needs to be resupplied with oxygen) enters the heart through the SUPERIOR AND INFERIOR ...
- Blood enters into the RIGHT ATRIUM
- Then it is squeezed through the TRICUSPID VALVE
- Blood then enters into the RIGHT VENTRICLE
- Then it is squeezed into the PULMONIC VALVE
How does blood flow through the heart step by step?
- Capillaries separate oxygenated blood from deoxygenated blood and arteries from veins
- After passing through the capillaries, blood is deoxygenated and needs to head back to the heart to be pumped to the lungs to pick up oxygen
- The Superior Vena Cava is the vein that gets deoxygenated blood from the upper body and returns it to the heart
What type of blood vessel usually carries oxygen poor blood?
- These are blood vessels that take oxygen-poor blood back to the heart.
- Veins become larger and larger as they get closer to the heart.
- The superior vena cava is the large vein that brings blood from the head and arms to the heart, and the inferior vena cava brings blood from the abdomen and ...
What controls the flow of blood in and out of the heart?
A series of valves control blood flow in and out of these chambers. Electrical impulses, controlled by the cardiac conduction system, make the heart muscle contract and relax, creating the rate and rhythm of your heartbeat. 1 Here are the steps of blood flow through the heart and lungs: The blood first enters the right atrium.
Where does blood enter the heart?
The blood enters the left atrium, then descends through the mitral valve into the left ventricle. The left ventricle then pumps blood through the aortic valve and into the aorta, the artery that feeds the rest of the body through a system of blood vessels. Blood returns to the heart from the body via two large blood vessels called ...
How does the heart work?
The heart works harder to bring oxygenated blood where it is needed. Disrupted or irregular heartbeats can affect blood flow through the heart. This can happen in multiple ways: Electrical impulses that regulate your heartbeat are impacted, causing an arrythmia, or irregular heartbeat.
Why do all four heart valves close?
All four of the heart valves open and close at just the right times to keep the blood flowing through the heart in the right direction. Part of the sound of your heartbeat is valves closing. 3 . Overview of the Four Heart Valves.
How many chambers does the heart have?
Updated on May 13, 2020. The heart is a complex organ, using four chambers, four valves, and multiple blood vessels to provide blood to the body. Blood flow itself is equally complex, involving a cyclic series of steps that move blood trough the heart and to the lungs to be oxygenated, deliver it throughout the body, ...
What is the function of the cardiovascular system?
This is the key function of the cardiovascular system: consuming, transporting, and using oxygen throughout physical activity (which includes when you are at rest). Disruptions in blood flow through the heart and lungs can have serious effects. artpartner-images / Getty Images.
Which artery transports oxygen rich blood?
The vena cavas pump blood into the right atrium and the cycle of oxygenation and transport begins all over again. Arteries generally transport oxygen-rich blood. The pulmonary artery is unique: It is the only artery in the human body that carries oxygen-poor blood. 2 .
Which chamber of the heart contracts to force blood to be high?
from here we drop into the left ventricle. This is the powerhouse chamber of the heart. As the heart contracts it forces blood at high pressure on its next journey.
How many questions are asked in the Heart and Circulatory System?
You’re guaranteed to get 5 to 8 questions on the heart and circulatory system.
What is the route back to the heart called?
The route back to the heart is called venous return. The Vena-Cava delivers deoxygenated blood into the right atrium of the heart. Now we’re back in heart [ Birmingham] we drop down in the right ventricle. Here, the right ventricle makes a forceful contraction. Pumping deoxygenated blood into the pulmonary artery.
What happens when you reach the capillaries?
Once we reach the Capillaries, the oxygen is dropped off into the bodies muscles.
What does London represent?
London represents the Lungs. Birmingham is the Heart << after-all, Birmingham is in the center of the UK. Just like the heart is in the center of the body. and Manchester represents the body’s muscles. The car is the red blood cell.
Where do we head away from the heart?
We head away from the heart via the Aorta and arteries.
Where does oxygen bind to?
Oxygen binds to a red blood cell at the lungs.
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.

How long is the blood vessel system?
This vast system of blood vessels - arteries, veins, and capillaries - is over 60,000 miles long. That's long enough to go around the world more than twice! Blood flows continuously through your body's blood vessels. Your heart is the pump that makes it all possible. Learn about Peripheral Artery Disease.
Which veins carry oxygen-poor blood back to the heart?
The veins (blue) take oxygen-poor blood back to the heart. Arteries begin with the aorta, the large artery leaving the heart. They carry oxygen-rich blood away from the heart to all of the body's tissues. They branch several times, becoming smaller and smaller as they carry blood further from the heart.
What are the small blood vessels that connect the arteries and veins?
Capillaries. Capillaries are small, thin blood vessels that connect the arteries and the veins. Their thin walls allow oxygen, nutrients, carbon dioxide and waste products to pass to and from the tissue cells.
Why is blood important?
Blood is essential. It carries oxygen and nutrients to your body's tissues. It takes carbon dioxide and waste products away from the tissues. It is needed to sustain life and promote the health of all the body's tissues. Cleveland Clinic is a non-profit academic medical center.
What is the heart nurse number?
Appointments 800.659.7822. Appointments & Locations. Talk to a Heart Nurse. Contact Us. As the heart beats, it pumps blood through a system of blood vessels, called the circulatory system. The vessels are elastic tubes that carry blood to every part of the body.
How does the superior vena cava work?
Veins become larger and larger as they get closer to the heart. The superior vena cava is the large vein that brings blood from the head and arms to the heart , and the inferior vena cava brings blood from the abdomen and legs into the heart. This vast system of blood vessels - arteries, veins, and capillaries - is over 60,000 miles long.
Blood Flow: Step by Step
Importance of Valves
- Without valves, the ventricles of the heart couldn’t build up any force or pressure. It would be like pumping up a flat tire with a huge hole in it. No matter how much effort you put into pumping, the tire would never inflate. In the case of the heart, blood would come into the chamber and just slosh through it. It would exit the valve at the bottom, or upward in the wrong direction each tim…
Blood Flow Changes
- A healthy heart normally beats anywhere from 60 to 70 times per minute when you're at rest. This rate can be higher or lower depending on your health and physical fitness. Athletes generally have a lower resting heart rate, for example. Your heart rate rises when you move. That's because your muscles use oxygen while they work. The heart works harder to bring oxygenated blood where i…
Summary
- Blood flow is a cycle that involves your lungs, heart chambers, valves, and blood vessels. Electrical pulses make your heart muscles squeeze and release. That action pushes blood through the two chambers on the right side of your heart and out to the lungs where it gathers oxygen. A vein then carries that oxygen-rich blood into the left side of the...
A Word from Verywell
- Healthy blood flow is critical to overall health. Physical activity is one of the best ways to make sure your heart and lungs can function well over time. If you have health issues, ask your healthcare provider about how to keep your heart rate and rhythm—and your blood flow—healthy.
