How is blood flow related to lung function

The pulmonary arteries carry deoxygenated blood to the lungs, where carbon dioxide is released and oxygen is picked up during respiration. Arteries are further divided into very fine capillaries which are extremely thin-walled. The pulmonary vein returns oxygenated blood to the left atrium of the heart.Latin: MeSH: System: 

How does oxygen flow through the lungs?

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.

How does blood flow through the circulatory system?

Video: Heart and circulatory 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 is cessation of blood flow?

The cessation or lessening of blood flow results ordinarily from an obstruction in a blood vessel that serves the lung.

What is the definition of lung infarction?

Lung infarction, death of one or more sections of lung tissue due to deprivation of an adequate blood supply. The section of dead tissue is called an infarct.

How does the oxygen go to the lungs?

From your pulmonic valve, blood travels to the pulmonary arteries and eventually to tiny capillary vessels in the lungs. Here, oxygen travels from the tiny air sacs in the lungs, through the walls of the capillaries, into the blood. At the same time, carbon dioxide, a waste product of metabolism, passes from the blood into the air sacs.

How does blood flow through the lungs?

How does blood flow through your lungs? Once blood travels through the pulmonic valve, it enters your lungs. This is called the pulmonary circulation. From your pulmonic valve, blood travels to the pulmonary arteries and eventually to tiny capillary vessels in the lungs.

Where does oxygen travel through the lungs?

This is called the pulmonary circulation. From your pulmonic valve, blood travels to the pulmonary artery to tiny capillary vessels in the lungs. Here, oxygen travels from the tiny air sacs in the lungs, through the walls of the capillaries, into the blood.

How does oxygen and carbon dioxide travel through the heart?

This prevents blood from flowing backward into the atria while the ventricles contract (squeeze). 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.
