Body System Overview

Body systems consist of groups of organs that collaborate for specific tasks.
An organ is a structure made up of various tissues working together for a designated function, such as the heart or brain.
An organism represents a fully functioning living system.

Digestive System

The digestive system breaks down food into smaller components for absorption into the bloodstream.
Nutrients from digested food provide energy for all body cells.

Excretory System

Responsible for waste removal from the body.
Helps maintain water balance, ensuring necessary substances exit the system.

Nervous System

Comprises a network of nerves that communicate signals between the brain and other body parts.
Functions as the control and communication system, regulating movements and sensory information.

Circulatory System

A vital system that transports essential materials, like oxygen and nutrients, to cells.
Removes waste products generated by cellular processes, ensuring homeostasis.

Respiratory System

Consists of organs that facilitate oxygen intake and carbon dioxide expulsion.
Plays a crucial role in maintaining respiratory health and supporting cellular respiration.

Skeletal System

The framework of bones and connective tissues that provides structure and support to the body.
Essential for movement, protection of organs, and storage of minerals.

Muscular System

Comprises tissues that facilitate movement of body parts and function of internal organs.
Muscle tissue is crucial for voluntary and involuntary movements, allowing the body to perform various activities.
