excretory sistem

The excretory system is a passive biological system that removes excess, unnecessary materials from an organism, so as to help maintain homeostasis within the organism and prevent damage to the body.

It is responsible for the elimination of the waste products of metabolism.

As it involves several functions that are only superficially related, it is not usually used in more formal classifications of anatomy or function.

Are healthier functioning bodies produce metabolic and other waste throughout the body depends on the system function; However, only bodies specifically for the excretion process are considered a part of the excretory system.

THE PARTS ARE :

Kidneys

The kidneys are bean shaped organs which are present in each of the sides of the vertebral column in the abdominal cavity. Humans have two kidneys and each kidney is supplied with blood from the renal artery. The kidneys remove the nitrogenous wastes such as urea from the blood, and salts.

Liver

The liver detoxifies and breaks down chemicals, poisons and other toxins that enter the body. For example, the liver transforms ammonia. The liver also produces bile, and the body uses bile to breakdown fats into usable fats and unusable waste.

Bile

 It`s then secreted within the small intestine where it helps to break down ethanol, fats and other acidic wastes including ammonia  into harmless substances.

Large intestine

The large intestine collects waste from throughout the body. It extracts any remaining usable water and then removes solid waste.
