The body’s way of keeping internal conditions stable, like temperature and blood sugar, even when the environment changes.

The smallest unit of matter that makes up all substances. Atoms combine to form molecules, which build cells and tissues.

A type of tissue that covers body surfaces and lines organs, protecting the body and helping with absorption and secretion.

Tissue made of fibers that contract to produce movement. There are three types: skeletal, cardiac, and smooth.

A nerve cell that sends electrical and chemical messages through the nervous system to control body functions.

The small space between two neurons where neurotransmitters carry signals from one cell to another.

A chemical messenger made by glands that travels through the bloodstream to regulate body functions like growth or metabolism.

Tiny air sacs in the lungs where oxygen passes into the blood and carbon dioxide leaves the body.

The functional unit of the kidney that filters blood, removes waste, and makes urine.

Homeostatic Imbalance

When the body can’t maintain stable internal conditions, leading to illness or disease (like dehydration or diabetes).
