Which vessels are responsible for gathering blood from capillaries into veins?

Venules are small blood vessels that play a crucial role in the circulatory system by collecting blood from the capillaries. After blood has passed through the capillary beds, where nutrient and gas exchange occurs, it is collected by the venules. These vessels then gradually converge to form larger veins, ultimately returning the deoxygenated blood back to the heart.

Understanding the role of venules in this process is important for grasping how the circulatory system functions as a whole. They serve as a vital link between the capillaries, where oxygen and nutrients are delivered to tissues, and the veins that carry the blood back toward the heart. This ensures efficient circulation and helps maintain proper blood flow and pressure throughout the body.
