Your answer is here:-
Explanation:
(a)- •Thyroid gland. location:base of throat. hormone secreted:thyroxine.
•adrenal gland. location:near the kidneys. hormone secreted:adrenaline.
•pancreas. location:near the liver. hormone secreted:insulin.
•testes. location:male genital orange. hormone secreted:testosterone.

(b)- Endocrine glands release chemical substances directly into the bloodstream or tissues of the body. The chemical substances released by the endocrine glands are known as hormones. Exocrine glands release chemical substances through ducts to outside the body or onto another surface within the body.
(c)- The flow of blood into the skin and digestive system reduces. As a result of the contraction. The arteries related to these muscles tend to an increased flow of blood to the skeletal system. As all these activities happen during stressful situations Adrenaline hormone is known as the Emergency hormone.
(d)- Lack of iodine can cause an abnormal enlargement of the thyroid gland, known as a goiter, and other thyroid problems.
(e)- If a person accidentally injects more insulin than required, e.g. because they expend more energy or eat less food than they anticipated, cells will take in too much glucose from the blood. This leads to abnormally low blood glucose levels (called hypoglycaemia).
