Functions of Hormone

 

A) Adrenaline :

1. Increase cardiac output
2. Vasoconstriction of blood vessel supplying gut,skin,reproduction organ, Vasodilution of blood vessel supplying skeletal muscle
3. Relaxation of smooth muscle of gut  and dilution of brochiole -> Enlargment of thorax to increase ventilation volume and oxygen uptake rate
4. Promote break down of glycogen to glucose by releasing ACTH
5. Increase sensitity of nerve system
6. Save heat by vasoconstriction of skin arteries

B) Noradrenaline :

1. Increase cardiac output
2. Vasoconstriction of all arteriole

C) Thyroxine :

1. Regulate growth and development
2. Increase metabolic rate
3. Produce heat
4. Increase cardiac output
5. Decrease blood glucose by increaseing metabolism
