1
functions of blood
transport of oxygen and carbon dioxide
carries nutrients from GIT to diff tissues
brings waste products to kidneys
distributes hormones to their target organs
2

composed of water, organic and inorganic substances, hormones and enzymes
Plasma
3
Blood w/o fibrinogen content
Serum

Consists 40-50% of blood volume
Solid elements
