In this manner, how many types of excretion are there?

Based on the excretory product, five modes of excretion are known in animals. They are: Ammonotelism (Type of excretion- ammonia) Ureotelism (Type of excretion – urea)

Furthermore, what are the three substances that the excretory system removes from the body? Excretion

Organ(s) Function
Lungs Remove carbon dioxide.
Skin Sweat glands remove water, salts, and other wastes.
Large intestine Removes solid waste and some water in the form of feces.
Kidneys Remove urea, salts, and excess water from the blood.

Thereof, what are the forms in which waste products are excreted?

All the metabolic wastes are excreted in a form of water solutes through the excretory organs (nephridia, Malpighian tubules, kidneys), with the exception of CO2, which is excreted together with the water vapor throughout the lungs. The elimination of these compounds enables the chemical homeostasis of the organism.

What is the mechanism of excretion?

Excretion is a process by which metabolic waste is eliminated from an organism. In vertebrates this is primarily carried out by the lungs, kidneys and skin. This is in contrast with secretion, where the substance may have specific tasks after leaving the cell. Excretion is an essential process in all forms of life.
