Delivering O2 and nutrients to body cells; Transporting metabolic wastes to lungs
and kidneys for elimination;
Transporting hormones from endocrine organs to target organs
Question:
12. Regulation functions of blood
Answer:
Maintaining body temperature by absorbing and distributing heat; Maintaining
normal pH using buffers; alkaline reserve of bicarbonate ions; Maintaining
adequate fluid volume in circulatory system with presence of plasma proteins and
sodium
Question:
13. Protection functions of blood
Answer:
Preventing blood loss due to plasma proteins and platelets initiating clot
formation
Preventing infection due to antibodies, complement proteins, WBCs
Question:
14. How does blood regulate pH levels?
Answer:
Blood plasma contains bicarbonate and proteins which act as buffers that may be
used to maintain pH; 7.4 needed for normal functioning
Question:
15. How does the blood regulate body temperature?
Answer:
Plasma absorbs and distributes heat. Blood vessels in dermis dilate to cool body
and to conserve heat.
