Explanation:
so there are fine capillaries which are present in the bronchioles(as it is the place where the oxygen and the carbon dioxide is exchanged between the air in the King's and the blood so the capillaries ensure that the blood has a direct interface with the air so the exchange of gases can be easier and the capillaries ensure that it increases the surface area in order to ensure effective exchange of gases). as these capillaries are very thin the blood flowing through them should be of low pressure because of the blood is sent with high pressure it can rupture the thin blood vessels(capillaries) causing internal bleeding which may clot and can cause a serious infection. but the blood in the rest of the body moves through arteries and veins(arteries carry the oxygenated blood whereas the veins carry the deoxygenated blood). he veins and the arteries have thick walls in order to withstand the high pressure with which the blood is sent to all parts of the body. hence the blood sent to the lungs is sent with a low pressure whereas the blood sent to different parts of the body is sent with high pressure.
