Ancient chinese medicine blood linked to energy flow. Ancient greece advocated bleeding as treatment for diseases (get rid of harmful blood) Medieval western medicine blood inhabited by good and evil spirits. Excretory (metabolic waste: nutritive, hormone transport (regulation) Temperature regulation: acid-base balance: normal ph range is very constant 7. 30-7. 45, protective: against microbs etc bad things. Comprised of ecf (plasma) and icf (inside blood cells) accounting for -7% of body mass (about 5l) May be studied in vivo or in vitro. Key terms: in vivo: inside the body, in vitro: removed from the body, normovolemia: normal blood volume, hypovolemia: lower blood volume, hypervolemia: higher blood volume. Hematocrit: percentage of blood volume occupied by rbc. 70 kg male should be about 45% (see diagram to the right)
