Explanation / Answer

Question: 2. Why is protection and support of the skeletal system a vital function?

Answer: The skeletal system (skeleton) provides the structural framework which supports and protect the organs and tissues of the body. The skeletal system keeps the body upright and also maintains its shape. The skeleton helps to protects vital internal organs such as brain, heart, lungs and spinal cord.

Section B:

Question: 1. Explain how the skeletal system performs the following functions.

Function Explanation Support The skeletal system (skeleton) provides the structural framework which supports the body and maintains its shape. Bones provide the point of attachment for skeletal muscles. The vertebrae support the weight of the body, and keeps the body upright. Protection The skeleton helps to protects vital internal organs such as brain, heart, lungs and spinal cord. The skull protects the brain, The rib cage protects the heart and lungs, and the vertebrae protect the spinal cord. Movement Skeletal muscles are attached to bones. Muscles, bones, and joints between the bones allow movement. The skeletal system allows to move, strech, and bend our body. Storage The bones acts as a reservoirs storing vital minerals such as calcium and phosphorus. Also fat which is a source of energy, is stored in the yellow bone marrow. Hematopoiesis Haematopoiesis is the production of blood cells that takes place in the bone marrow. Hence the skeletal system is the site of the haematopoiesis
