Question

How does our body respond when adrenaline is secreted into the blood?

Answer 1

Ans. Adrenaline hormone is secreted in large amounts when a person is frightened, or mentally disturbed. When it reaches the heart, it beats faster to supply more oxygen to our muscles.

Answer 2

If more adrenaline is released then the responses would be as follows :

(i) The glucose concentration of the blood would increase as the glycogen will be converted to glucose rapidly.

(ii) The muscles would gain more power due to availability of more glucose.

(iii) The heart beat will increase .

(iv) Thus more blood will be pumped.

(v) Thus the blood supply to muscles would increase .

(vi) The person would have perspiration .

The adrenaline is hence also called the emergency hormone as it helps either to fight danger or to run away from danger.
