Blood
FUNCTIONS of blood:
- Transport
- Buffering action
- Maintenance of constant body temperature
- Defense
Transport of:
(?) to facilitate gas exchange (O2 and CO2)
(?) to tissues where they will be metabolized or assimilated
(?) to the excretory organs
(?) that regulate cell functions
gases
products of digestion
waste products of catabolism
hormones and other endocrine secretions
Blood assists in the preservation of an almost neutral reaction in the tissues
Buffering action
Helps maintain normal water balance and fluid distribution
Buffering action
Circulating blood minimizes variations in local temperature
Maintenance of constant body temperature
Phagocytosis
Defense
Blood contains proteolytic enzymes and antibodies that help destroy foreign bodies.
Defense
Color:
Normally red as imparted by hemoglobin.
Viscosity:
3 - 5 x more viscous than water
Circulates in
liquid state
Coagulates between (?) after removal from the body
5 10 minutes

Liquid portion of an unclotted blood

Solid Portion
Solid Portion:
RBC (erythrocytes, erythroplastids, normocytes)
WBC (leukocytes; leukoplastids)
Platelets (thrombocytes; thromboplastids)
: small refractive colorless particles in the blood that are probably granules from blood cells or minute fat globules.
Hemoconia
Portion where exchange between O2 and CO2 for normal respiration occurs.
