Identify the hormone with its correct matching of source and function:
A Oxytocin – posterior pituitary, growth and maintenance of mammary glands
B Melatonin – pineal gland, regulates the normal rhythm of sleep-wake cycle
C Progesterone – corpus luteum, stimulation of growth and activities of female secondary sex organs
D Atrial natriuretic factor – ventricular wall, increases the blood pressure

Detailed Solution

Melatonin is secreted by the pineal gland and regulates the 24-hour (diurnal) rhythm, including the sleep-wake cycle.
Atrial natriuretic factor comes from the atrial wall and lowers blood pressure.
