Arterioles are small blood vessels that carry oxygenated blood away from the heart to the capillaries, while venules are small blood vessels that collect deoxygenated blood from the capillaries and carry it back to the heart. Arterioles typically have thicker walls and are more muscular than venules to help regulate blood flow and pressure, while venules have thinner walls and lower pressure.
Arterioles are smaller vessels that carry blood away from the heart, while venules are smaller vessels that carry blood back to the heart. By observing the direction of blood flow and the presence of valves (which venules have), one can distinguish between arterioles and venules in the frog's foot vasculature.
Double circulation consists of pulmonary circulation, where blood circulates between the heart and the lungs to pick up oxygen and release carbon dioxide, and systemic circulation, where oxygenated blood circulates between the heart and the rest of the body to deliver oxygen and pick up carbon dioxide.

The venules draining the small intestine combine to form the superior mesenteric vein.
Yes, blood can flow through shunts when precapillary sphincters are closed, allowing for blood to bypass the tissue cells. Shunts are direct connections between arterioles and venules that can help regulate blood flow, especially in situations where blood flow needs to be redirected.

Capillaries are the tiny connecting bridges between arterioles and venules. They are responsible for the exchange of gases, nutrients, and waste products between the bloodstream and surrounding tissues.
Capillaries are microscopic blood vessels that connect arterioles to venules. These blood vessels facilitate the movement between the blood and the tissues.
To exchange oxygen and nutrients between arterioles and venules
capillaries
any of the fine branching blood vessels that form a network between the arterioles and venules.
Arterioles are the small arteries that lead into the capillaries, which connect to cells in the body. Venules are the small veins that the capillaries flow back into, leaving the cells.
No; arteries (and arterioles) depend on smooth muscle contraction, whereas veins (and venules) have valves.
Arteioles are blood vessels that connect arteries and capillaries. Capillaries are blood vessels that connect arterioles and venules
