Which heart chamber receives blood from the pulmonary veins?
left atrium
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.
Which heart chamber does blood enter and exit respectively?
The right atrium is one of the four chambers of the heart. The heart is comprised of two atria and two ventricles. Blood enters the heart through the two atria and exits through the two ventricles.
Where does blood enter at the end of the pulmonary circulation?
The right circuit is the portion of the circulatory system which carries deoxygenated blood away from the right ventricle, to the lungs, and returns oxygenated blood to the left atrium and ventricle of the heart….

How does a drop of blood travel through the heart?
Blood enters the heart through two large veins – the posterior (inferior) and the anterior (superior) vena cava – carrying deoxygenated blood from the body into the right atrium. Blood flows from the right atrium into the right ventricle through the tricuspid valve.
What kind of blood is transported to the lungs in pulmonary circulation?
Pulmonary circulation transports oxygen-poor blood from the right ventricle to the lungs, where blood picks up a new blood supply. Then it returns the oxygen-rich blood to the left atrium.
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 …
Where does the pulmonary vein enter the left atrium?
After leaving the hilum, the right pulmonary vein passes posterior to the superior vena cava and right atrium to enter the left atrium. The left pulmonary veins pass in front of the descending aorta to enter the left atrium.
Where does blood go after it enters the heart?
Blood enters the right atrium from the superior and inferior venae cavae, and the coronary sinus. From right atrium, it goes through the tricuspid valve to the right ventricle. From the right ventricle, it goes through the pulmonary semilunar valves to the pulmonary trunk
Where does the blood go after it leaves the lungs?
The four pulmonary veins (two from each lung) bring freshly oxygenated blood from the lungs to the left atrium. From the left atrium, the blood travels to the left ventricle from where it is ejected to supply oxygen and nutrients to all of the tissues of the body.
When does blood enter the pulmonary blood vessels?
It’s only at the moment of birth when a baby takes its first breath that blood enters the pulmonary blood vessels to enter the lungs. 2 It is the exposure to oxygen that closes the shunts that bypass the pulmonary vein and other vessels—this relaxes these vessels so that blood can enter.
