NEET PG DENTAL EXAM

Detailed explanation-1: -The pulmonary artery and the aorta, on the other hand, carry blood out of the heart, and therefore carry blood at tremendous pressure owing to the systolic pressure of the ventricles.

Detailed explanation-2: -Arteries have thick walls so they can handle the high pressure and velocity that expels your blood out of your heart. Veins carry blood back to your heart from the rest of your body. The pressure of the blood returning to the heart is very low, so the walls of veins are much thinner than arteries.

Detailed explanation-3: -Blood pressure is much greater in arteries than in veins because of the pumping action of the heart.

Detailed explanation-4: -In humans, blood pressure is usually measured indirectly with a special cuff over the brachial artery (in the arm) or the femoral artery (in the leg).
