Albumin and globulin are the two major proteins found in the blood. Albumin is produced in the liver and is important for transporting many molecules in the blood and making sure that the blood does not leak into the tissues of the body.lbumin and globulin are the two major proteins found in the blood.

The arterioles then divide further into capillaries. Capillaries are the smallest blood vessels and their walls are only one cell thick which allows diffusion between the blood and cells to occur. Nutrients and oxygen from the blood diffuses through the capillary walls into the tissues that need it. This is aided by the relatively high blood pressure that also squeezes the oxygen and nutrients through the capillary wall and into the cells of the tissue. At the same time carbon dioxide and other waste products re-enter the capillary in order to be processed and removed from the body.
3. Arterioles-smallest arteries, these carry blood into capillaries. a. When these constrict, they shut off blood to specific tissues. When they dilate, blood flow increases greatly into tissues. III. CAPILLARIES-microscopic blood vessels. Are the smallest vessels in the body.rterioles carry blood into capillaries (capillary beds) which. carry blood into body tissues. B. Blood returning from the capillary beds empties into venules that merge to form veins. Veins. ultimately empty into the heart. II. ARTERIES-carry blood away from the heart.
