Answer 1

1. Oxytocin

2. Calcitonin

Calcitonin secreted by parafollicular cells of the thyroid gland in humans, and in many other animals. Its function is to decrease calcium levels in the blood and thus acting as antagonist of parathyroid hormone (PTH).

3. Thyroid gland

The thyroid gland consists of two lobes which surrounds the cricoid and tracheal cartilages.

4. Adrenal glands

The adrenal glands are also known as suprarenal glands, being endocrine in nature that produce a many hormones including adrenaline and the steroids aldosterone and cortisol. These are located above the kidneys.

5. Hormone

these are special chemical messengers which are synthesized in glands, transported to their target via blood where they perform their specified function

6. Beta cells

Pancrease has three different types of cells viz

Alpha which secrete glucagon

Beta cells secrete insulin

Delta cells secrete somatostatin.

7. Endocrine glands are glands of the endocrine system that secrete their products, hormones, directly into the blood rather than through a duct. Example the pineal gland, pituitary gland, , thyroid gland, adrenal glands. parathyroid gland, hypothalamus,pancreas, ovaries, testes

8. tropic hormone

9.thyroxine

10. thymus

Aldosterone	steriod	Aldosterone regulates the balance of water and electrolytes in the body, encouraging the kidney to excrete potassium into the urine and retain sodium, thereby retaining water.
Thyroxine	Derivatives of the the amino acid tyrosine	It plays vital roles in digestion, heart and muscle function, brain development and maintenance of bones.
Vasopressin	peptide	Stimulates reabsorption of water, conserves water
Adrenaline	catecholamine.	Helps body to adapt to long term stress, mobilizes fat and increases blood sugar level
ACTH	Peptide	The function of ACTH is to regulate levels of the steroid hormone cortisol, released from the adrenal gland.
Epinephrine	catecholamine.	Helps body to adapt to long term stress, mobilizes fat and increases blood sugar level. It is also called stress hormone.
oxytocin		Stimulates uterine contractions
