b) Testes are male reproductive organs which produce male hormone testosterone that regulates the secondary sexual characters in males.


c) The pancreas secretes insulin which regulates blood sugar level. It converts excess sugar into glycogen and stores it in the liver.


d) Adrenal gland secretes aldosterone which regulates the correct salt balance in our body. It balances sodium potassium levels in our body and helps in water retention.
