Organ System Working Together - Waste Removal

Vocabulary flashcards covering dissolved and solid waste removal, the urinary system, and the excretory system based on the lecture notes.

Body Wastes

Substances that the body no longer needs, produced after nutrients are used for energy, growth, and repair.

Dissolved Wastes

Waste products such as urea, excess salts, and extra water that mix with water in the blood and travel through the bloodstream.

Solid Wastes

Materials from undigested food that the body cannot digest or absorb.

Urinary System

The body system made up of the kidneys, ureters, bladder, and urethra that removes dissolved wastes from the blood and regulates body fluids.

Kidneys

The main organs of the urinary system that act as filters to clean the blood, remove waste substances, excess water, and salts, and form urine.

Urine

A liquid waste product formed when the kidneys filter blood, containing collected wastes and extra water.

Ureters

Tubes that connect the kidneys to the bladder and transport urine away from the kidneys.

Bladder

An organ that temporarily stores urine and expands as it fills to allow controlled waste release.

Urethra

The tube that carries urine out of the body during the process of urination.

Urination

The process of releasing urine from the body through the urethra.

Excretory System

The body system including the large intestine, rectum, and anus that eliminates solid wastes from the body.

Large Intestine

The main organ for solid waste formation that absorbs water from undigested food to turn waste into solid feces, while housing helpful bacteria that aid digestion.

Rectum

The organ that temporarily stores solid waste (feces) until the body is ready to eliminate it.

Anus

The final opening of the excretory system surrounded by muscles that control the release of solid waste.

Defecation

The process of eliminating solid waste from the body through the anus.

Homeostasis

The internal balance maintained in the body by regulating water, salts, and toxins.
