what are the composition of blood?
55% plasma
44% erythrocytes
<1% buffy coat
what are the functions of blood?
-Carries oxygen from lungs to tissues and carbon dioxide from tissues to lungs -Carries waste products for elimination -Conveys raw materials -Transfers hormones -regulates water content, temperature and alkalinity -Protects against infection -Contains coagulation factors
what are the major plasma proteins?
ALBUMIN GLOBULIN IMMUNOGLOBULINS, FIBRINOGEN COMPLEMENT PROTEINS
what do you call a plasma that leaves the circulatory system or in vitro
serum
-it is composed of nutrients, respiratory gases, nitrogenous waste products,
hormones and electrolytes
plasma
it is a solvent where the formed elements are suspended and proteins and solutes are dissolved
water
exert osmotic force to retain the fluid w/in the microvasculature
albumin
transports lipid, iron ions, metal ions in bloodstream?
alpha & beta globulins
antibodies w/ various immune functions
gamma globulins
- precursor of fibrin
- participates in blood coagulation
fibrinogen
all proteins serve to buffer againts pH changes
plasma proteins
consists of enzymes, proenzymes, hormones & complement system
regulatory proteins
