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. The pulmonary veins empty oxygen-rich blood from the lungs into the left atrium.
The right side of your heart receives oxygen-poor blood from your veins and pumps it to your lungs, where it picks up oxygen and gets rid of carbon dioxide. The left side of your heart receives oxygen-rich blood from your lungs and pumps it through your arteries to the rest of your body.
Your heart is sort of like a pump, or two pumps in one. The right side of your heart receives blood from the body and pumps it to the lungs. The left side of the heart does the exact opposite: It receives blood from the lungs and pumps it out to the body.
What vein brings blood to the heart from the lungs?

What brings oxygenated blood to the heart from the lungs?
There are two main circuits in the body: the pulmonary circuit and the systemic circuit. ...
While most arteries carry oxygenated blood in the body, the pulmonary arteries carry de-oxygenated blood to the lungs.
The main pulmonary artery, or the pulmonary trunk, transports de-oxygenated blood from the heart to the lungs.
Blood enters the right atrium and passes through the right ventricle. The right ventricle pumps the blood to the lungs where it becomes oxygenated. The oxygenated blood is brought back to the heart by the pulmonary veins which enter the left atrium. From the left atrium blood flows into the left ventricle.
How does blood flow through the body step by step?
With each rhythmic pump of the heart, blood is pushed under high pressure and velocity away from the heart, initially along the main artery, the aorta. In the aorta, the blood travels at 30 cm/sec. From the aorta, blood flows into the arteries and arterioles and, ultimately, to the capillary beds.
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) ...
How does blood flow into the heart?
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. As the atrium contracts, blood flows from your right atrium into your right ventricle through the open tricuspid valve.
How do you remember the blood flow through the heart?
Just remember this mnemonic for the order of blood flow through the valves:Try. Performing. Better. Always. (Tricuspid, Pulmonary, Bicuspid, and Aortic.)All. People. Enjoy. Time. Magazine. ... Stenosis of a valve. Partial obstruction. Aneurysms. Mitral or aortic regurgitation. Septal defect.
Blood Flow Step by Step
The heart has two upper chambers—the left and right atriums—and two larger lower chambers—the left and right ventricles. A series of valves act like doorways to control blood flow in and out of these chambers. The cardiac conduction system sends out electric impulses to make the heart muscle contract and relax. Those p…
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…
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…
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, partner with your healthcare provider to determine the best way to keep your heart rate and rhythm—and your blood flow—healthy. It's one of the most important things you can do for a long life.

Each time your heart beats, it pumps out oxygen- and nutrient-rich blood to your body. Blood flows through a network of vessels called the circulatory system. When blood returns to your heart, it flows to your lungs to receive oxygen. Then your heart pumps that blood out to the rest of your body, and the process begins again.

· The blood enters the heart's right atrium and is pumped to your right ventricle, which in turn pumps the blood to your lungs. The pulmonary artery then carries the oxygen-poor blood from your heart to the lungs. Your lungs add oxygen to your blood. The oxygen-rich blood returns to your heart through the pulmonary veins.

There are three main types of blood vessels. Arteries. The arteries (red) carry oxygen and nutrients away from your heart, to your body's tissues. 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.

· Your heart is your cardiovascular system’s fluid pump. 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.’ Your blood flows via the heart in two individual loops.

· Each time the heart beats it pumps blood through the body. When we exert ourselves physically, our heart beats faster. This increases the speed at which blood flows through our body. The blood can then absorb more oxygen from the lungs per minute in order to supply the body’s cells with more oxygen.
