Name the main hormone secreted by adrenal glands? Give its function.

Answer :

Adrenaline is the hormone secreted by adrenal glands.

Following are its functions:

It acts on heart and due to this heart starts beating faster. Due to this fast beating more blood is supplied to muscles and ultimately they get more oxygen.

The blood supply is diverted from digestive system and skin due to contraction of muscles around these small arteries.

Breathing rate is also increased due to contraction of diaphragm and ribs.

All these functions then contribute to fight a person with difficult situations and to deal with them.
