Subtitle: Ways Waste is Excreted from the Body
The body consists of many systems that work together to keep us healthy and functioning properly. One of these systems is the waste excretion system, which is responsible for eliminating excess waste from the body. Waste is excreted from the body in four ways: through the urine, feces, sweat, and respiration.
Urine: Urine is the most common way the body excretes waste. Urine is composed of water, electrolytes (such as sodium and potassium), urea, and other wastes. Urine is produced in the kidneys and stored in the bladder until it is excreted.
Feces: Feces is the solid waste that is eliminated from the body through the digestive system. It is made up of undigested food, bacteria, and other waste products. Feces is produced in the large intestine and stored in the rectum until it is excreted.
Sweat: Sweat is a liquid composed of water, electrolytes, and other wastes that is excreted through the skin. Sweat is produced in the sweat glands and is released through the pores in the skin.
Respiration: Respiration is the process of inhaling oxygen and releasing carbon dioxide. Carbon dioxide is a waste product of cellular respiration and is excreted through the lungs.
