The kidneys are two bean-shaped organs, each about the size of a fist. They are located just below the rib cage, one on each side of your spine. Healthy kidneys filter about a half cup of blood every minute, removing wastes and extra water to make urine.
*Micturation*
Urination; the act of urinating.
Osmoregulation
Osmoregulation refers to the physiological processes that maintain a fixed concentration of cell membrane-impermeable molecules and ions in the fluid that surrounds cells.

Answer:
(a) Excretion: The process of removal of chemical wastes especially nitrogenous waste from the body is known as excretion.
(b) Kidney: Kidneys are primary excretory organs eliminating nitrogenous wastes mainly urea from the blood and throwing it out of the body in the form of urine.
(c)micturation: Micturition, or urination, is the act of emptying the bladder. When the bladder is full of urine, stretch receptors in the bladder wall trigger the micturition reflex. The detrusor muscle that surrounds the bladder contracts. ... It must be relaxed for urine to flow through the urethra and outside the body.
(d)Osmoregulation: the maintenance of constant osmotic pressure in the fluids of an organism by the control of water and salt concentrations.
