Solution 8

(i) Hormone - The secretions of endocrine glands which are carried by blood to the target organs are called hormones.
(ii) Endocrine gland - The glands without ducts which secrete hormones are called endocrine glands.
(iii) Exocrine gland - The glands with ducts which secrete enzymes are called exocrine glands.
(iv) Hypothyroidism - It is the under secretion of thyroxine by thyroid gland which leads to retarded growth and mental development in infants.
(v) Hyperglycemia - Increase in blood sugar level is called hyperglycemia.
(vi) Hypersecretion - The over activity of any gland leads to over secretion of hormones called hypersecretion.

Solution 9

Solution 10

(i) Diabetes mellitus - Diabetes mellitus is a disease caused by the deficiency of insulin hormone.
(ii) Beta cells - Beta cells are the cells of pancreas that secrete insulin.
(iii) Exophthalmic goitre - The over activity of thyroid gland leads to its enlargement, producing a big swelling in the neck region called exophthalmic goiter.  
(iv) Releasing hormones - A substance produced by the hypothalamus that is capable of accelerating the secretion of a given hormone by the anterior pituitary gland.

Solution 11

Solution 12

Insulin secreted by pancreas controls the level of glucose in blood.

Solution 13

Adrenaline is called an emergency hormone because it brings rapid physiological responses to emergencies like danger, fear or other situations requiring vigorous action.

Solution 14

Solution 15

Solution 16

Solution 18

Insulin is a protein hormone and if it is given orally it would be digested upon by the protein digesting enzymes in the alimentary canal.

Solution 19

(i) The endocrine cells present in pancreas are: alpha cells, beta cells and delta cells.
(ii) Insulin and glucagon.
(iii) Insulin - It lowers the glucose level in the blood.
