There are 4 excretory organs in human: The skin, the lungs, the liver, and the kidney (Urinary system). The skin excretes the sweat outside the body through numerous pores in the surface of this organ. Sweat is a mixture of three metabolic wastes: water, salts, and urea.

What is excretion short answer?

Excretion, the process by which animals rid themselves of waste products and of the nitrogenous by-products of metabolism . Through excretion organisms control osmotic pressure—the balance between inorganic ions and water—and maintain acid-base balance.

What is the filter unit of the kidneys called?

The kidneys remove urea from the blood through tiny filtering units called nephrons . Each nephron consists of a ball formed of small blood capillaries, called a glomerulus, and a small tube called a renal tubule.

What are the 7 functions of the kidney?

A – controlling ACID-base balance.
W – controlling WATER balance.
E – maintaining ELECTROLYTE balance.
T – removing TOXINS and waste products from the body.
B – controlling BLOOD PRESSURE.
E – producing the hormone ERYTHROPOIETIN.
D – activating vitamin D.

How do kidneys remove waste products?

What color is urine when your kidneys are failing?

When kidneys are failing, the increased concentration and accumulation of substances in urine lead to a darker color which may be brown, red or purple .
