Document Summary

Delivering o2 lungs + nutrients [gi] to cells. Metabolic waste [cells] to lungs (co2), kidneys, liver. Hormones [endocrine glands] to target cells: regulation. Temperature: distribute heat to body skin (heat loss) Blood proteins prevent fluid loss to tissue spaces. Blood clotting (platelets) prevent blood loss if blood vessel damaged. White blood cells and antibodies in blood prevent infection. Dr. frank feiner: erythrocytes are 45% of whole blood (hematocrit, most dense component, healthy males: 47 +/-5%, healthy females: 42 +/-5% Blood plasma is 90% water but more than 100 dissolved solutes: nutrients, gasses, hormones/wastes/other cell product, electrolytes (sodium, chloride), proteins, proteins. Variety of functions but unlike nutrients (ex: glucose, fatty and amino acids), not for cell fuel. Acts as a carrier to shuttle certain molecules through the circulation. The major blood protein contributing to the plasma osmotic pressure (the pressure that helps to keep water in the bloodstream: composition varies continuously: cells add/remove stuff.
