Answer:
Arteriole is a small branch of an artery that leads in to a capillary.
Explanation:
Arteriole:
- The connections between your arteries and capillaries are known as arterioles, which are tiny blood channels that transport blood out from your heart.
- Through the use of their muscles, they may adjust their diameter to regulate your blood pressure and blood flow throughout your body.
- They connect to capillaries as well to exchange waste, nutrients, and oxygen.
Function of Arterioles:
- Capillary beds, which serve as the locations of exchange with bodily tissues, receive blood from arteries.
- Capillaries exit the body and return to venules, which are tiny blood arteries that eventually enter larger veins and return blood to the heart.
- Arterioles are considered as the main resistance veins because they distribute blood flow into capillary beds.
- The majority of the body's overall blood flow resistance and 80%, is provided by arterioles.
