Homeostasis definition and why its important

Homeostasis is the body’s ability to maintain a stable internal environment despite changes outside the body. It’s essential because it keeps body functions like temperature, pH, and glucose levels within a normal range so cells can work properly.

4 main types of biomolecules found in the body

carbohydrates lipids proteins nucleic acids

proteins act as enyzmes, hormones, and structural materials

main function of epithelial tissue

to cover body surfaces, line organs and cavities, and to provide protection, secretion, and absorption.

tough, protective protein found in the outer layer of the skin which helps prevent water loss/protects against injury

2 main components of skeletal tissue

bone tissue and cartilage, provides structure, protection, and support.

moves: forms part of the structure that slides during muscle contraction

pulls: uses energy from ATP to pull on actin filaments.
