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 ...
What are the 18 steps of blood flow?
- Step. Superior / Inferior vena cava.
- Step. Right Atrium.
- Step. Tricuspid Valve.
- Step. Right Ventricle.
- Step. Pulmonary Valve.
- Step. Pulmonary Arteries.
- Steps. Lungs (get O2)
- Step. Pulmonary viens.
What is the correct order of blood flow through the heart?
Blood flows from the right atrium into the right ventricle through the tricuspid valve . When the ventricle is full, the tricuspid valve shuts to prevent blood flowing backwards into the atrium. Blood leaves the heart through the pulmonic valve into the pulmonary artery and flows to the lungs.
What are the 20 steps of blood flow?
- superior and inferior vena cava. deoxygenated.
- right atrium. deoxygenated.
- tricuspid valve. deoxygenated.
- right ventricle. deoxygenated.
- pulmonary valve. deoxygenated.
- pulmonary trunk. deoxygenated.
- pulmonary arteries. deoxygenated.
- lungs. pulmonary capillaries in the alveoli.
How does blood flow through the heart step by step?
- The blood first enters the right atrium.
- The blood then flows through the tricuspid valve into the right ventricle.
- When the heart beats, the ventricle pushes blood through the pulmonic valve into the pulmonary artery.
What’s the main artery called?
The largest artery is the aorta , the main high-pressure pipeline connected to the heart’s left ventricle. The aorta branches into a network of smaller arteries that extend throughout the body. The arteries’ smaller branches are called arterioles and capillaries.
Do all arteries carry oxygen-rich blood?
Arteries carry blood away from the heart. In all but one case, arteries carry oxygen-rich blood . The exception is the pulmonary arteries. They carry oxygen-poor blood away from the heart, to the lungs, to pick up more oxygen.
What is the proper direction of blood flow?
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.
What is the largest artery in the body?
Aorta Anatomy
The aorta is the large artery that carries oxygen-rich blood from the left ventricle of the heart to other parts of the body.
What is the pathway of blood?
Oxygen and carbon dioxide travels to and from tiny air sacs in the lungs, through the walls of the capillaries, into the blood. Blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs. Blood leaves the heart through the aortic valve, into the aorta and to the body.
What kind of blood is associated with the right side of the heart?
The right side of your heart receives oxygen-poor blood from your veins and pumps it to your lungs, where the blood 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.
Which artery connects the heart to the lungs?
In the lungs, the pulmonary arteries (in blue) carry unoxygenated blood from the heart into the lungs. Throughout the body, the arteries (in red) deliver oxygenated blood and nutrients to all of the body’s tissues, and the veins (in blue) return oxygen-poor blood back to the heart.
How does blood move through the body?
Blood primarily moves in the veins by the rhythmic movement of smooth muscle in the vessel wall and by the action of the skeletal muscle as the body moves . Because most veins must move blood against the pull of gravity, blood is prevented from flowing backward in the veins by one-way valves.
Where does blood from the right ventricle go?
The right ventricle (RV) pumps oxygen-poor blood through the pulmonary valve (PV) into the main pulmonary artery (MPA) . From there, the blood flows through the right and left pulmonary arteries into the lungs.
What is blood flow defined as?
Blood flow refers to the movement of blood through the vessels from arteries to the capillaries and then into the veins . Pressure is a measure of the force that the blood exerts against the vessel walls as it moves the blood through the vessels.
What chamber does blood come from to enter the aorta?
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 . The left ventricle pumps the blood to the aorta which will distribute the oxygenated blood to all parts of the body.
