capillaries
Epithelial tissues receive nutrients through diffusion from nearby blood vessels or from the underlying connective tissue. Nutrients can also be transported through the epithelial cells via active transport mechanisms.
Avascular tissues receive nutrients through diffusion from neighboring blood vessels or surrounding tissues. These tissues depend on a close proximity to a blood supply to maintain their metabolic functions.
True. Epithelial tissues do not contain blood vessels, which is why they rely on diffusion from nearby blood vessels in connective tissues for their nutrient and oxygen supply.
oxygen and carbon dioxide exchange between the circulatory system and tissues occurs at the capillaries, which are the smallest blood vessels where nutrient and gas exchange takes place through diffusion. Oxygen from the blood is released into the tissues, and carbon dioxide from the tissues is taken up by the blood to be transported back to the lungs for elimination.
The capillaries are the primary sites of exchange between blood and tissues. Capillaries are small blood vessels with thin walls that allow for the exchange of oxygen, nutrients, and waste products between the blood and the surrounding tissues. These exchanges are essential for maintaining the proper function of tissues in the body.
Those would be capillaries.

Diffusion of oxygen and carbon dioxide takes place primarily in the capillaries, which are the smallest blood vessels in the body. Capillaries have thin walls that allow for the exchange of these gases between the bloodstream and the surrounding tissues.
The pressure that forces fluid from vessels into tissues is called hydrostatic pressure. This pressure is created by the heart pumping blood through the blood vessels, causing fluid to be pushed out of the vessels and into the surrounding tissues.
