Removal of metabolic waste products to maintain homeostasis.

Bean-shaped organs filtering blood and producing urine.

Remove carbon dioxide and water vapor through breathing.

Excretes sweat containing water, salts, and urea.

Removes toxins and old red blood cells via bile.

Eliminates solid waste (feces) from the body.

Functional units of kidneys responsible for filtering blood.

Regulation of blood pH by kidneys.

Sweat contains water, salts, urea, and ammonia.

Hypothalamus detects temperature changes and triggers sweating.

Liver can regenerate even if up to 75% is damaged.

Liver plays a central role in metabolism, detoxification, and excretion.

Bile contains bilirubin and bile salts, secreted for digestion.

Urea is formed during the breakdown of amino acids.

Feces consist of undigested food, bacteria, and metabolic waste.

Peristalsis moves feces to the rectum for elimination.

Process where blood is filtered for waste in the glomerulus.

Initial liquid consisting of water, salts, glucose, and waste products.

Process of nutrients like water and glucose being taken back into the bloodstream.

Final product of kidney processing; contains waste, excess water, and toxins.

Mainly carbon dioxide and water vapor expelled during breathing.

Sweat glands transport waste from blood to the skin for elimination.

Substances including ammonia, urea, uric acid, carbon dioxide, and excess salts and water that are eliminated from the body.

Organs like kidneys, lungs, skin, and liver that are responsible for excretion.

Regulate the excretion process through filtration, reabsorption, and secretion.

A reflex triggered when the rectum is stretched, prompting waste elimination.

Hormones like ADH, aldosterone, and ANP help maintain water and electrolyte balance in the body.

The method by which waste products are separated from blood in the kidneys.

The maintenance of stable internal conditions in the body, which excretion helps support.
