Question

Is the correct order of blood flow capillaries, arteries, arterioles, veins, venules; arterioles, arteries, capillaries, veins, venules; veins, venules, capillaries, arterioles, arteries; or arteries, arterioles, capillaries, venules, veins?

Answer 1

The last one...

Explanation:

The Aorta is the main highway that receives blood from the heart. It splits into Arteries, these split into smaller arterioles, then even smaller capillaries .

After the Erythrocytes (red blood cells) have done their work (exchanging `O_2` for `CO_2`), the process reverses: From the capillaries into the venules, then into the larger the veins and ultimately back to the heart. (via the Superior Vena Cava and the Anterior Vena Cava ).
