Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which one of the following is the correct pathway of gas exchange?
A
vein-venule-capillary-arteriole-artery
B
artery-arteriole-capillary-venule-vein
C
venule-vein-capillary-artery-arteriole
D
capillary-arteriole-artery-venule-vein
Explanation: 

Detailed explanation-1: -From the capillaries, blood passes into venules, then into veins to return to the heart.

Detailed explanation-2: -Blood leaving the systemic capillaries returns to the heart (right atrium) via venules & veins (and no gas exchange occurs while blood is in venules & veins). This blood is then pumped to the lungs (and the alveolar capillaries) by the right ventricle.

Detailed explanation-3: -Blood flows into your kidney through the renal artery. This large blood vessel branches into smaller and smaller blood vessels until the blood reaches the nephrons. In the nephron, your blood is filtered by the tiny blood vessels of the glomeruli and then flows out of your kidney through the renal vein.

Detailed explanation-4: -Deoxygenated blood starts to run from the body. It flows into Superior/ Inferior Vena Cava. The flow of deoxygenated blood reaches the right atrium. The atrium will push the flow through the Tricuspid valve. The gore stays in the right ventricle. More items •30-Mar-2022
