Human Body Systems and Cells

The powerhouse of the cell, responsible for producing energy through cellular respiration.

The outer layer of a cell that acts as a barrier, controlling what enters and exits the cell.

The process by which cells reproduce, creating two identical daughter cells.

The sum of all chemical reactions occurring within a living organism, converting nutrients into energy and eliminating waste.

A type of tissue that provides support, protection, and binds other tissues together. Examples include bones, cartilage, ligaments, tendons, blood, and fat.

A type of connective tissue that provides structural support and flexibility.

A type of connective tissue that connects bones to bones.

A type of connective tissue that connects muscles to bones.

Connective tissue that stores energy and makes the body smooth and contoured.

A protein fiber that provides strength and elasticity to connective tissue.

A protein fiber that gives tissues flexibility and the ability to stretch.

This tissue provides a protective lining for cavities and surfaces of the body. It forms skin, mucous membranes, and linings of organs.

Tissue that contracts and allows movement of the body.

This specialized tissue transmits messages throughout the body, coordinating all functions.

The colorless, gel-like fluid within a cell that contains nutrients for growth, reproduction, and repair.

The genetic material of a cell, found in the nucleus, determines traits like eye, skin, and hair color.

The largest organ in the body, responsible for protection, temperature regulation, sensation, vitamin D production, and absorption.

Provides the body's framework, protects vital organs, and allows for movement.

Consists of muscles that allow for movement, shape the body, and support skeletal tissue.

Carries messages and coordinates bodily functions through the brain, spinal cord, and nerves.

Delivers blood throughout the body, working with the lymphatic system to maintain health and fight infections.

Protects the body from disease by fighting toxins and foreign substances. Includes the spleen and lymph.

Controls growth, development, and other bodily functions through hormones produced by specialized glands.

Responsible for sexual reproduction and passing on genetic information.

The study of the structure of organisms and their parts.

The study of how the different parts of an organism function together.

The study of tissues and cells under a microscope.

The dense, active protoplasm in the cell center

The basic unit of living organisms. Cells are responsible for all life processes.

The process of breaking down food for absorption of nutrients.

The system of organs and tissues that takes in oxygen and eliminates carbon dioxide.

The process of converting nutrients into energy for cell function and removing waste.

A collection of tissues that work together to perform specific functions.
