Select the answer which correctly matches the endocrine gland with the hormone it secretes and its function/ deficiency symptom.

Endocrine gland	Hormone	Function/ deficiency symptoms
(A) Anterior pituitary	Oxytocin	Stimulates uterus contraction during childbirth
(B) Posterior pituitary	Growth Hormone(GH)	Over-secretion stimulates abnormal growth
(C) Thyroid gland	Thyroxine	Lack of iodine in diet results in goitre
(D) Corpus luteum	Testosterone	Stimulates spermatogenesis

i. A
ii. B
iii. C
iv. D

Hint: The glands in the human body are of two types-endocrine and exocrine. The exocrine glands are the one which pours their secretions into the blood via ducts whereas the endocrine glands are the ones which pour their secretions into the blood directly. The system in humans is created from the endocrine glands and their secretions called hormones. Examples of these are as follows:
Endocrine: GH, FSH, LH, TSH, ACTH, ADH, etc.
Exocrine: sweat gland, salivary gland, mammary gland, ceruminous gland, etc.

Complete step by step answer: The (ductless gland) anterior pituitary secretes hormonal secretion like the Growth hormone(GH), thyrotropin (TSH), ACTH (ACTH), Luteinizing Hormone (LH), Follicle stimulating (FSH), and gonadotropic hormone(GH).
 The second endocrine gland which is the posterior pituitary secretes the Antidiuretic secretion (ADH), additionally, it is known as vasopressin which acts as a vasoconstrictor or in other words, is vasoconstrictive in nature. This hormone helps the kidneys to extend water absorption within the blood.
The progestogen is secreted by corpus luteum.
 The thyroid gland which is an endocrine gland secretes thyroid hormone thyroxine that helps to maintain the regulation of the body's rate, heart, and organic process functions, etc. The body wants iodine to form thyroid hormones. So, this lack of iodine in diet ends up in a malady known as goiter.
So, the proper answer is (iii) Thyroid gland- Thyroxine- Lack of iodine in diet results in goitre.

Note: The body's hormones, and also the glands that turn out for them, form up the system. There are about eight major glands, and their job is to control the body's metabolism, growth, and sleep. Just like the systema Nervosa, the system is associated with a data signal system. If endocrine glands were absent with the hormones they unharness our cells would not apprehend to try and do vital things. As an example, take your bones they would not get the message that it is time for you to grow and get larger.
