NEET PG DENTAL EXAM

Detailed explanation-1: -Venules are the smallest veins and receive blood from capillaries. They also play a role in the exchange of oxygen and nutrients for water products. There are post-capillary sphincters located between the capillaries and venules. The venule is very thin-walled and easily prone to rupture with excessive volume.

Detailed explanation-2: -Your blood enters your venules before joining up with your veins. Your veins then carry your blood back to your heart where it can refuel. This oxygen-poor blood enters your heart through two large veins called your superior vena cava and inferior vena cava.

Detailed explanation-3: -They provide a connection between arteries and capillaries, acting as a “middle man” when the larger arteries and tiny capillaries want to trade oxygen, nutrients and waste. Venules (small veins) taking blood back to your heart join capillaries to take part in these exchanges.
