vessel walls must be thin to allow ease to transfer of molecules to these tissues i had this on a test and i got it right :)
The capillaries found in the alveoli, nephrons, and vili are thin-walled and narrow. This size and construction makes it easier for nutrients, oxygen, and wastes to diffuse from body tissues.
Wherever capillaries are found, these are places where nutrients and wastes are exchanged.
smooth muscle
The capillaries connect arteries and veins. They are found throughout the body.
Alveoli are found within the lungs. The alveoli act as a specialised gaseous exchange surface in mammals. Another function of alveoli is the production of surfactant.
Simple Squamous are found in ventral body cavities, alveoli and capillaries in the lings, in the kidneys, capillaries where diffusion and osmosis occur, all vessels, and the heart.
you have 2 lungs. they are both located inside your rib cage, protected by the rib bones.
veins, arteries, and capillaries
Capillaries are located between arteries and veins. They are found throughout the body.
Veins don't have pulses, arteries have pulses. Arteries are blood supply tubes, veins are blood return tubes. Between the arteries and the veins blood passes through tiny tubes called capillaries. The pressure changes that cause the pulse can't pass through these tiny tubes.
The capillaries are the smallest blood vessels and are usually found between arteries and veins.
The three types of blood vessels in the body are veins, arteries, and capillaries. Arteries carry blood away from the heart. Veins carry blood to the heart. Capillaries are microscopic vessels that are found in the lungs and muscles.
