- defense
3
Q
transport function of blood
A
- gases to facilitate gas exchange (O2 to CO2)
- products of digestion to tissues where they will be metabolized or assimilated
- waste products of catabolism to the excretory organs
- hormones and other endocrine secretions that regulate cell functions
4
Q
buffering action of blood
A
- blood assists in the preservation of an almost neutral reaction in the tissues
- helps maintain normal water balance and fluid distribution
