Excretory_system

The Excretory System is the system of an organism\'s body that performs the function of excretion, the bodily process of discharging wastes. It is responsible for the elimination of wastes produced by homeostasis. There are several parts of the body that are responsible for this process, such as the sweat glands, the liver, the lungs, and the kidney system. It removes wastes of the organism, balancing and regulating the chemical composition of its body fluids. The excretory system eliminates excretory products from the body, collects water and filters body fluids. Its parts include anything that aids in depleting wastes and unneeded substances. Without a properly functioning excretory system. the accumulated wastes cause damage to the body.

Outline of the excretory system

• Foreign Cells
• Malphigian tubule system (Arthropod excretory system)
• Menses

Functions

The Excretory System:

• Gets rid of wastes.
• Eliminates useless by-products excreted from cells.
• Eradicates harmful chemical build-ups.
• Develops early in the womb.
• Maintains a steady, balanced chemical concentration.

Lungs

Lungs are two-sponge like organs localized in each side of the thorax. They are constituted by pulmonary alveoli. They are not responsible for converting Oxygen into Carbon dioxide, but to maintain life supporting levels of these two gases in blood stream by excreting the extra carbon dioxide and keeping a regular supply of oxygen. Each and all organism\'s cells can take the oxygen through passive diffusion from the bloodstream and use it in its own metabolism, thus producing carbon dioxide that will be further excreted when passing through alveoli circulation.

Skin

The skin is another part of the system, containing sweat that help regulate the concentration in one’s body while also keeping him or her cool. The salt helps evaporate the water, cooling off the skin. Sweat is excreted through sweat glands. There are two types of sweat glands: Eccrine sweat glands and Apocrine sweat glands. The basic purpose of skin is to provide a waterproof, protective, covering for the body\'s complex internal environment.The skin also plays a key rules in helping to maintain the circulatory and nervous system.

Eccrine

The Eccrine glands secrete mostly water and salt and are used by the body for temperature control. These glands are located all around the body but are most profuse around the soles of the feet, palms of the hands, and the forehead. They look like coiled tubes, spiraling towards the exterior of the skin.

Liver

The liver - a vital part of the excretory system, and the human body. It regulates glycogen storage, plasma protein synthesis, and drug detoxification. The liver secretes bile, a base used for breaking down fats. Therefore, it helps get rid of unneeded wastes in the body. It changes toxic ammonia, which is a poisonous gas , to urea, a harmless fluid.The kidney filters urea(a mix of sugar and waste) into a liquid called urine. The liver is the largest gland in the body.
