The document provides an overview of the major body systems, including the integumentary, digestive, nervous, reproductive, muscular, skeletal, renal, respiratory, and circulatory systems. Each system is comprised of different organs and tissues that work together to perform important functions like protection, movement, waste removal, nutrient transport, and maintaining homeostasis. The body systems coordinate to keep the human body functioning properly.

1. Overview of Body Systems

2. Body Systems
• Body systems are organ systems within the body that
work together to help the organism grow, develop, and
maintain homeostasis.
• They include:
– Integumentary system
– Digestive system
– Nervous system
– Reproductive system
– Muscular system
– Skeletal system
– Renal system
– Respiratory System
– Circulatory system

3. Integumentary system
• Protects the body against damage and water loss,
regulates body temperature, removes wastes,
senses things
• Contains:
– Skin – largest organ in the body
– Hair or fur
– Scales
– Feathers
– Nails
– Hooves

4. Digestive System
• Breaks down food for use by
the body
• Contains
– mouth
– Esophagus
– Stomach
– Spleen
– Liver
– Pancreas
– Small intestine
– Large intestine
– Rectum
• Food particles are absorbed
into the blood and travel
throughout the body.
• Removes waste

5. Nervous system
• Coordinates all movement and
sensory information for the
entire body
• Controls, interprets, and reacts
• Contains:
– Brain
– Spinal cord
– All other nerves

6. Reproductive System
• Contains sex organs and glands that influence
gender, reproduction, maturity, and all
changes that happen in the body during
adolescence.
• Female – ovaries, fallopian tubes, uterus,
vagina
• Male – testes, penis, urethra, prostate

8. Muscular system
• Responsible for all movement of
the body
• Controlled by the nervous system
• Contains all muscles within the
body, including:
– Skeletal muscles
– Heart (cardiac muscles)
– Smooth muscles (in digestive and
other systems)

9. Skeletal system
• Provides structure and
protection for the body
• 206 bones in a human adult
• Contains all bones in the
body

10. Renal system
• Removes waste from the
body
• Regulates blood volume,
blood pressure, controls
electrolyte levels, regulates
blood pH
• Contains:
– Kidneys
– Ureters
– Bladder
– urethra

11. Respiratory system
• Regulates the intake and exchange of Oxygen
and Carbon Dioxide
• Contains:
– Lungs
– Trachea
– Diaphragm
– Mouth and nose

12. Circulatory system
• Circulates blood
throughout the body
• Transports nutrients to
every part of the body
• Contains:
– Heart
– Veins
– Arteries
– capillaries
