The human body is a very complex and well organized machine packed with so many systems that interact with one another in a bid to maintain life. One of the most significant systems is the one of the skeletal systems. The question that appears to be indispensable in the biology as well as the anatomy is:
Fill-in-the-Blank Question:
One reason the skeletal system is important is because __________.
A) It pumps blood through the body
B) It helps digest food
C) It provides structure and support to the body
D) It filters waste from the bloodstream
Correct Answer: C) It provides structure and support to the body
Explanation:
The first fact which makes the skeletal system significant is that it makes the human body to have structure and support. Without the bones, we could not stand, sit, or walk not to mention move purposefully.
The skeletal system however does much more than just support. It affects several crucial functions in the soundness and functionality of the body in many ways. These are some more reasons why it is so necessary:
- Protection of internal organs: Ribs and the other bones protect the most important body organs. To give an example; the skull covers the brain, the ribs protect heart and lungs, and the spinal column does the same for spinal cord.
- Movement and mobility: Bones, in conjunction with the muscles, provide movement. Joints and muscles together coordinate to make us move, as well as in everyday activities, including walking, lifting, writing, and dancing. The muscles connect with the bones, and when there is contraction of those muscles, they exert pressure on the bones, hence causing them to move.
Understanding the Skeletal System
The skeleton of the adult human body consists of 206 bones and that is divided into two important sections:
- Axial skeleton: It includes the skull, the vertebral column, the rib cage. It gives central support and supports the internal organs.
- Appendicular skeleton: It constitutes pelvic bones, shoulders, arms, and legs. It enhances transport and dialogue with the environment.
FAQs
Q1: How does the skeletal system protect the body?
Skeletal system is a tough shield surrounding important organs. An example of such protection is like the rib cage protects the heart and lungs and the skull surrounds the brain and the two are therefore covered to protect against any injury.
Q2: Can bones repair themselves after an injury?
Yes. Bones are able to their injury with a great healing power after fracture. The joint takes several weeks to months to heal, which depends on the severity as well as the age of the individual, involving inflammation, bone production, and bone remodeling.
Q3: What is the role of bone marrow in the skeletal system?
Red blood cells, white blood cells and platelets are produced by the bone marrow located in the empty center of select bones. This is an important role of transporting oxygen and protection against disease.
Q4: Why is calcium important for bones and how is it stored?
Calcium supports the existence of strength as well as hardness in bones. The bone is a reserve of superfluous calcium that resorts at certain times of need and ensues a balance that is very essential to both the muscles and the nerves.
Final Thoughts
Skeletal system is not only the rigid structure that supports us. Among the reasons why it is important is the fact that it provides structure and support to the body, enabling us to maintain posture and carry on the necessary physical activity. Simultaneously, it is the body guard, a blood cell maker, and a mineral bank.
Knowledge about the skeletal system is not only a pleasure to observe the biological wonders of the human organism, but it is also a reminder that taking care of bones, eating well, and doing exercise is essential to maintain health.
