Answer (1)
The skeletal system gives shape to our body. This system is made up of bones and cartilage which not only gives structure and support but also facilitates movement, protects organs, and produces blood cells.
Thirty-three vertebrae make a backbone. The backbone, or spine, is a crucial structure that offers support and flexibility to our body. It is divided into different sections known as cervical, thoracic, lumbar, sacral, and coccygeal regions.
The heart pumps blood to all parts of the body. It is a muscular organ responsible for circulating oxygen and nutrients to cells and removing carbon dioxide and other wastes through the blood.
The liver produces bile juice. Unlike organs that store substances, the liver secretes bile, which helps in the digestion of fats. It also plays essential roles in metabolism and detoxification.
The excretory system helps to remove the waste matter from the body. This system includes organs such as the kidneys, bladder, and urethra that work together to eliminate waste products and help maintain the body's chemical balance.
