  • 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.
