HUMAN ORGANS

Human organs:

The 11 organ systems include the integumentary system, skeletal system, muscular system, lymphatic system, respiratory system, digestive system, nervous system, endocrine system, cardiovascular system, urinary system, and reproductive systems.

The main systems of the human body are:

1. Circulatory system / Cardiovascular system:

Circulates blood around the body via the heart, arteries, and veins, delivering oxygen and nutrients to organs and cells and carrying their waste products away.

Keeps the body's temperature in a safe range.

2. Digestive system and Excretory system:

System to absorb nutrients and remove waste via the gastrointestinal tract, including the mouth, esophagus, stomach, and intestines.

Eliminates waste from the body.

3. Endocrine system:

Influences the function of the body using hormones.

4. Integumentary system / Exocrine system:

Skin, hair, nails, sweat, and other exocrine glands

5. Immune system and lymphatic system:

Defends the body against pathogens that may harm the body.

The system comprises a network of lymphatic vessels that carry a clear fluid called lymph.

6. Muscular system:

Enables the body to move using muscles.

7. Nervous system:

Collects and processes information from the senses via nerves and the brain and tells the muscles to contract to cause physical actions.

8. Renal system and Urinary system

The system where the kidneys filter blood to produce urine and get rid of waste.

9. Reproductive system:

The reproductive organs are required for the production of offspring.

10. Respiratory system:

Brings air into and out of the lungs to absorb oxygen and remove carbon dioxide.

11. Skeletal System:

Bones maintain the structure of the body and its organs.
