110. Vessels and functional properties of the pulmonary circulation.
Explains the pulmonary circulation, which carries deoxygenated blood from the heart to the lungs and returns oxygenated blood to the heart. It goes through the pulmonary arteries, with their branching into lobar and segmental arteries for each lung, then the pulmonary veins and venules, and finally the capillaries around the alveoli. Two tables list the segmental arteries and the pulmonary veins for the right and left lungs.

PULMONARY VESSELS
The pulmonary circulation is a specific part of the circulatory system responsible for carring deoxygenated blood from the heart to the lungs, and returning oxygenated blood back to the heart.
The vessels that are involved in :
1. Pulmonary Arteries:
→ All arteries carry oxygenated blood except pulmonary arteries
Carries deoxygenated blood from the right ventricle of the heart to the lungs
Pulmonary trunk.
Right pulmonary art
left pulmonary art.
Branches.
2. Pulmonary veins :
The 4 pulmonary veins return oxygenated blood to the left atrium of the heart. (exception)
+ Pulmonary venuls : small vessels the O₂ blood passes through them before reaching the pul. veins.
3. Pulmonary Capillaries :
Within the lungs, the pulmonary arteries branch into a network of tiny capillaries.
These capillaries surround the alveoli (air sacs) in the lungs, facilitating the exchange of carbon dioxide for oxygen during respiration.
