Organ Systems

1. Circulatory 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.
   • Equalizes temperature in the body
   • Platelets ensure that the blood can clot and heal over time, while red blood cells ensure that oxygen reaches vital organs.

2. Digestive system:

   • Mechanical and chemical processes that provide nutrients via the mouth, esophagus, stomach and intestines.
   • Eliminates waste from the body.

3. Endocrine system:

   • Provides chemical communications within the body using hormones.

4. Integumentary system/Exocrine system:

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

5. Lymphatic system/Immune system:

   • The system comprising a network of lymphatic vessels that carry a clear fluid called lymph.
   • Defends the body against pathogenic viruses that may endanger the body .

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/Urinary system/Excretory system:

   • The system where the kidneys filter blood.

9. Reproductive system:

   • The sex organs required for the production of offspring.

10. Respiratory system:

    • The lungs and the trachea that bring air into and out of the body.

11. Skeletal system:

    • Bones supporting the body and its organs.

Bone to bone connection - ligament

Bone to muscle connection - tendon

Both ligament and tendon are made up of collagen (specially type-1 collagen and type-3 collagen and elastin)
