justify that pancreas and gonads perform dual function .
Pancreas are known to have a dual function because it acts as both an endocrine gland and exocrine gland i.e. it is a part of both the hormonal and digestive system of the body respectively. So, it is also called heterocrine gland.
It secretes hormones insulin and glucagon as well as digestive enzymes.
Gonads perform dual functions one is the production of gametes, in addition to this they also show endocrine function by producing sex hormones. for example ovary is the primary reproductive organ and performs dual function.
1. Production of female gamete: Ovum
2. Secretion of female sex hormones: estrogen and progesterone.
