Question

Pulmonary circulation from the hierarchy list. This will highlight the circulatory route that takes deoxygenated blood to the lungs and returns oxygenated blood back to the heart.The largest of these vessels, the _______________________________, immediately branches into the right and left _______________________________ as it leaves the heart.

Answer 1

Pulmonary circulation will highlight the circulatory route that takes deoxygenated blood to the lungs and returns oxygenated blood back to the heart.

The largest of these vessels, the Pulmonary trunk, immediately branches into the right and left Pulmonary arteries as it leaves the heart.

• Pulmonary circulation is the system of transportation that shunts de-oxygenated blood from the heart to the lungs to be re-saturated with oxygen before being transporting it into systemic circulation.

• The pulmonary circulation begins at right ventricle and ends on left atrium.

Blood from the right ventricle to the pulmonary trunk.

⬇️

The pulmonary trunk splits into Right and left Pulmonary arteries.

⬇️

The pulmonary arteries transport the deoxygenated blood to arterioles and capillary beds in the lungs.

⬇️

Carbon dioxide is released and oxygen is absorbed.

⬇️

Oxygenated blood then passes from the capillary beds through venules into the pulmonary veins.

⬇️

Oxygenated blood comes to the left atrium through the pulmonary veins which is transported to different body organs and tissues (systemic circulation).
