Developmental Biology
Arterioles are small blood vessels that branch from arteries and lead into capillaries, playing a critical role in regulating blood flow and pressure within the circulatory system. They are muscular and can constrict or dilate, allowing them to control the distribution of blood to various tissues and organs based on their metabolic needs. This regulation is essential for maintaining homeostasis and is closely linked to the processes of vasculogenesis and angiogenesis.
