Which of the following statements is correct in relation to the endocrine system?
1 Only (i) and (iii)
2 Only (ii)
3 Only (iii) and (iv)
4 Only (i) and (ii)
Explanation:
(b) Hormones are non-nutrient chemicals which act as intercellular messengers and are produced in trace amounts.
Gastrointestinal tracts secretes four major peptide hormones - gastrin, secretin, cholecystokinin (CCK) and gastric inhibitory peptide (GIP) while juxtaglomerular cells of kidney secretes erythropoietin, a peptide hormone. Releasing and inhibitory hormones are produced by hypothalamus. Neurohypophysis or posterior pituitary is under direct neural regulation of the hypothalamus.

Explanation:
(c) Adrenal Medulla is called emergency gland and secretes adrenaline (epinephrine) and nor-adrenaline (nor-epinephrine) hormones.
Adrenaline (epinephrine) is commonly called as 'emergency hormone' or 3F-hormone (For fear, fight & flight). It stimulates sweating, heart beat and breathing rate. It causes the dilation of coronary artery (supplying blood to the heart muscles), bronchioles (for increasing inspiratory volume) and pupil (for better vision).

Explanation:
(b) Oxytocin, a neurohypophysial hormone, is produced by the hypothalamus and stored and secreted by the posterior pituitary gland. It stimulates contractions of the smooth muscle tissue in the wall of the uterus during childbirth. Progesterone is a female hormone produced by the ovaries during release of a mature egg from an ovary (ovulation). Progesterone helps prepare the lining of the uterus (endometrium) to receive the egg if it becomes fertilized by a sperm. If the egg is not fertilized, progesterone levels drop and menstrual bleeding begins. Atrial natriuretic factor is a hormonal substance produced by the right atrium of the heart that stimulates the excretion of sodium and water by the kidneys and helps regulate blood pressure.
