All the following are functions of the skeleton EXCEPT:
A Protection of internal organs
B Support the weight of the body against the force of gravity
C Transport of nutrients throughout the body
D Storage of fat and minerals
The correct answer and explanation is:
The correct answer is C: Transport of nutrients throughout the body.
The skeleton has several important functions in the human body, but nutrient transport is not one of them. The main functions of the skeleton include protection, support, storage, and blood cell production.
- Protection of internal organs: The skeleton provides a protective framework for vital organs. For example, the rib cage protects the heart and lungs, while the skull shields the brain from injury.
- Support the weight of the body against the force of gravity: The bones of the skeleton, particularly the spine, support the body’s weight and provide the structure needed to stand upright and move.
- Storage of fat and minerals: The bones store important minerals like calcium and phosphorus. These minerals can be released into the bloodstream as needed. Additionally, the bone marrow stores fat, which serves as an energy reserve.
- Production of blood cells: Bone marrow, located inside certain bones, is the site of blood cell production, including red blood cells, white blood cells, and platelets.
On the other hand, the transport of nutrients is a function performed by the circulatory system, not the skeleton. The circulatory system, consisting of the heart and blood vessels, is responsible for carrying oxygen, nutrients, hormones, and waste products throughout the body. Blood vessels, including arteries, veins, and capillaries, are the primary channels through which nutrients and other substances are transported to cells and organs.
In conclusion, while the skeleton plays a crucial role in structural support, protection, and storage, nutrient transport is outside its scope of responsibilities. The circulatory system is the main system involved in the transport of nutrients.
