What is homeostasis and why is it important?

Homeostasis is the body's ability to maintain a stable internal environment, despite external changes. It keeps factors like temperature, pH, and blood sugar balanced so the body cells can function properly.

The anatomical position is standing upright, facing forward, arms at side, palms forward. Directional terms such as: superior, inferior, anterior and posterior helps explain the location of one body part in relation to another.

Atoms are the smallest units of matter that still have the properties of an element. They are made of protons, neutrons, and electrons.

What does the periodic table show?
