Question

Describe the transport of gases in a pulmonary circuit

Answer 1

Answer:

Pulmonary circulation moves blood between the heart and the lungs. It transports deoxygenated blood to the lungs to absorb oxygen and release carbon dioxide. The oxygenated blood then flows back to the heart. ... It sends oxygenated blood out to cells and returns deoxygenated blood to the heart.

Answer 2

Deoxygenated blood is carried from the heart to the lungs and then, oxygenated blood is carried from the lungs back to the heart.

• The deoxygenated blood through the vena cava is brought to the heart and then carried by the pulmonary artery to the lungs.
• In the lungs, diffusion of gases take place between the blood capillaries and the aerioles present in the lungs.
• The capillaries are formed by the branching of the pulmonary artery around the aerioles that consist of the air inhaled.
• The oxygen from the aerioles is diffused into the capillaries and the carbon dioxide from the capillaries is diffused into the aerioles.
• The carbon dioxide from the aerioles are exhaled and the capillaries join and form the pulmonary vein that carries the oxygenated blood into the heart.
