Main Organ Systems of the Human Body
-
Circulatory System/Cardiovascular System
- Transports blood throughout the body using the heart, arteries, and veins.
- Delivers oxygen and nutrients to organs and cells while removing waste products.
- Helps maintain body temperature within a safe range.
-
Digestive System/Excretory System
- Absorbs nutrients and eliminates waste.
- Comprises the gastrointestinal tract including the mouth, esophagus, stomach, and intestines.
-
Endocrine System
- Influences body functions through hormones.
- Regulates metabolism, growth, and mood among other bodily functions.
-
Exocrine System
- Secretes substances through ducts for various physiological functions.
- Includes systems such as sweat and salivary glands.
-
Integumentary System
- Consists of the skin and its appendages: hair, nails, sweat glands, and oil glands.
- Protects the body, helps regulate temperature, and facilitates sensory perception.
-
Immune System/Lymphatic System
- Defends against pathogens that can cause illness.
- Contains lymphatic vessels that transport lymph, a fluid that plays a role in the immune response.
-
Muscular System
- Facilitates movement via skeletal, smooth, and cardiac muscles.
- Enables the body to perform a wide range of physical activities.
-
Nervous System
- Collects and processes sensory information through a network of nerves and the brain.
- Coordinates physical actions by signaling muscles to contract.
-
Reproductive System
- Comprises organs necessary for producing offspring.
- Includes reproductive organs like ovaries and testes.
-
Respiratory System
- Facilitates the exchange of gases by bringing air into and out of the lungs.
- Absorbs oxygen and removes carbon dioxide from the body.
-
Skeletal System
- Provides structural support for the body and protects vital organs.
- Consists of bones, cartilages, and ligaments.
-
Urinary System/Renal System
- Filters blood through kidneys to produce urine.
- Eliminates waste and helps regulate blood pressure and electrolytes.
