Document Summary

Temperature -> divergence of blood from superficial to deeper vessels regulates temperature of the body: protection: a) clotting -> mechanism against blood loss; b) immune -> leukocytes protect against pathogens. Blood vessels: arteries carry blood from the heart; veins carry blood towards the heart; capillaries are the smallest and most numerous blood vessels, permitting exchange of fluid, nutrients and waste: lymphatic: Lymphatic vessels: located in connective tissues around blood vessels, carries fluid called lymph. Lymph nodes: clean the lymph before it is returned to venous blood. Interstitial fluid (tissue fluid): blood plasma that passes out of capillary walls into surrounding tissue because of hydrostatic pressure. Arterial blood: blood leaving the heart; bright red because of the oxyhemoglobin complex. Venous blood: blood returning to the heart; darker because of the lack of oxygen. When centrifuged, plasma ( 55% of blood) separates to top and formed elements ( 45%) sink to the bottom.
