What is the flow of blood in the pulmonary capillaries?

The pulmonary trunk splits into the right and left pulmonary arteries. These arteries transport the deoxygenated blood to arterioles and capillary beds in the lungs. There, carbon dioxide is released and oxygen is absorbed. Oxygenated blood then passes from the capillary beds through venules into the pulmonary veins.

What is the correct order of blood flow through a capillary?

Through the thin walls of the capillaries, oxygen and nutrients pass from blood into tissues, and waste products pass from tissues into blood. From the capillaries, blood passes into venules, then into veins to return to the heart.

How does blood flow through the pulmonary system?

The oxygen-poor blood fills the right atrium and then flows to the right ventricle, where it is pumped to the lungs through the pulmonary arteries. The lungs refresh the blood with a new supply of oxygen, which comes from the air that you breathe in.

What happens when blood passes through pulmonary capillaries?

Blood flows through the tricuspid valve into the right ventricle. It then flows through the pulmonic valve into the pulmonary artery before being delivered to the lungs. While in the lungs, blood diverges into the numerous pulmonary capillaries where it releases carbon dioxide and is replenished with oxygen.

What is the function of pulmonary capillaries?

In the pulmonary capillaries, carbon dioxide is exchanged for oxygen from the alveoli. The blood leaving the lungs, which now has a high oxygen content and a relatively low carbon dioxide content, is distributed to the tissues of the body by the left side of the heart.

What is the correct order of blood flow for the pulmonary circuit quizlet?

Blood enters the pulmonary arteries and travels to the lungs. Blood enters the pulmonary veins. Blood enters the left side of the heart. Blood enters the systemic arteries.

Which type of blood flows through the pulmonary vein?

Oxygen-rich blood
Oxygen-rich blood flows from the lungs back into the left atrium (LA), or the left upper chamber of the heart, through four pulmonary veins. Oxygen-rich blood then flows through the mitral valve (MV) into the left ventricle (LV), or the left lower chamber.

Where does blood go from pulmonary capillaries?

The now oxygen-rich and carbon dioxide-depleted blood travels from the pulmonary capillaries through the pulmonary veins and into the left atrium of the heart for transit to the left ventricle and the systemic circulation.

What do the pulmonary capillaries do?

Pulmonary capillaries have extremely thin walls to allow rapid exchange of respiratory gases across them.

What are the 18 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) …
