The Excretory System

Function:

The job of the excretory system is to remove the waste from the body that is not needed, and also rids the body of natural gases that can be fatal if not released. Wastes that are removed are water, carbon dioxide, salt, urea, and uric acid.

Organs:

Kidney

Skin

Ureter

Bladder

Urethra

More about Skin:

The skin removes the body of wastes such as salt, urea, and uric acid through sweat. Along with ridding the body of waste, the skin's other function is to keep water inside the body.

Reasons for having skin:

• Keeps foreign particles that could cause diseases out of your body.
• Lets you touch and feel things around you.
• Helps you regulate your body temperature.
• Gets rid of waste.

Tissues that make up skin:

Elastic Tissue

Connective Tissue

Epithelial Tissue

Interactions with other systems:

• Interacts with integumentary system, because the integumentary system uses skin as an organ and so does the excretory, because it is one way to remove wastes.
• Interacts with digestive system. After food is digested it makes its way out the body through a process called excretion, which is the whole process of the excretory system.

Diseases, Disorders & Other Problems:

• Gout is a disorder involving the excretory system in which there is an excess amount of uric acid that the kidney is not getting rid of.
• Kidney failure is also relevant in the excretory system, and the only cure would be a kidney transplant.
