Functions of skeletal system
1. Support -It forms a rigid framework and supports the weight of the body against gravity.
2. Shape – It provides and maintains the shape of the body.
3. Protection – It protects the delicate internal organs of the body.
4. Acts as reservoir – It stores minerals such as calcium and phosphate. Fat (triglyceride) is stored in yellow bone marrow and represents a source of stored energy for the body.
5. Locomotion – It acts as lever along with the muscles attached to it.
6. Strength – It can withstand heavy weight and absorbs mechanical shock.
7. Asa haemopoietic tissue – Red and white blood cells are produced in the bone marrow of the ribs, spongy bones of vertebrae and extremities of long bones.
