   1. Kidney

   2. Hypothalamus

   3. Uterus

   4. Adrenal gland

   5. Pituitary gland

Answer 1

1. The part that does not secrete hormones as a part of the endocrine system is Muscle and bones.

The hypothalamus, pituitary, and pineal gland in the brain works as endocrine glands and secretes hormone. The ovaries and test-es also secrete hormones as estrogen and progesterone in females and testosterone in males. Pancreas also work as endocrine gland as well as exocrine. This secretes insulin and glucagon. Kidneys secrete renin and erythropoietin.

2.Calcitonin is a hormone of the thyroid gland

3. The adrenal medulla is the outer layer of adrenal gland. It secrets the corticoids i.e Mineralo,Glucocorticoids,Androgens And Adrenalins. So the correct answer is all of the above.

4. The main link between the nervous and endocrine systems is the Hypothalamus. It links the nervous system and endocrine system via pituitary gland. The pituitary gland is the master gland that is controlled by hypothalamus.

5. The target organ for ADH is tubular cells of kidney. It increases epithelial permeability to water, allowing increased water reabsorption.
