How are the skeletal system and muscular system related or similar in function?
A The skeletal system provides mineral storage, while the muscular system functions in the absorption of minerals.
B They both function in support within the human body.
C They both function in blood formation.
D They both produce heat.
The correct answer and explanation is :
The correct answer is:
B. They both function in support within the human body.
Explanation (300 words):
The skeletal and muscular systems work closely together to support and enable movement in the human body. This relationship is known as the musculoskeletal system. Each system has unique roles but they collaborate to maintain posture, stability, and body function.
The skeletal system consists of bones, cartilage, and ligaments. One of its main functions is to provide structural support for the body. It serves as the framework that supports organs and muscles. Bones also protect vital organs—for example, the skull protects the brain, and the rib cage protects the heart and lungs.
The muscular system, composed of muscles and tendons, also contributes to body support. Muscles are attached to bones via tendons, and when they contract, they pull on bones to produce movement. Muscles also help maintain posture and body position by continuously making small adjustments to counteract gravity.
Although both systems have additional roles, support is a shared and fundamental function. The skeletal system provides the rigid framework, while the muscular system enables that framework to move and remain stable.
Let’s briefly address the other options:
- A is incorrect because the skeletal system does store minerals like calcium and phosphorus, but the muscular system does not absorb minerals. Muscle tissue uses minerals but does not absorb or store them in the same way bones do.
- C is incorrect because only the skeletal system—specifically, the bone marrow—plays a key role in blood formation (hematopoiesis). Muscles do not form blood.
- D is incorrect because only the muscular system, especially skeletal muscles, contributes significantly to heat production through muscle contraction (thermogenesis). The skeletal system does not produce heat.
Thus, B is the best answer as both systems work together to provide support to the human body.
