Question

the 12 body systems (skeletal, muscular, and integumentary system)
learning target:

success starter:

1. how does the respiratory system help the circulatory system?
2. why do you think muscles are important??

1.

1. muscles are important because

body system #1 : skeletal system
the skeletal system is the frame of the body that is held together by tendons, ligaments, and cartilage. the skeleton helps humans move and is involved in making blood cells (red and white) and storing calcium.
related disease: osteoporosis : lowers calcium in bones making them thinner and easier to break.
why is the skeletal system important?

body system #2 : nervous system
a system of nerves and the spinal cord that sends messages to the rest of the body.

Explanation:

1. For the respiratory-circulatory system question: The respiratory system takes in oxygen, which enters the bloodstream (circulatory system) to be delivered to body cells, and removes carbon dioxide waste carried by the circulatory system from cells.
2. For muscle importance: Muscles enable movement, support posture, aid organ function, and generate body heat.
3. For skeletal system importance: It provides body structure, enables movement with muscles, produces blood cells, and stores calcium for bodily functions.

Answer:

1. The respiratory system supplies oxygen to the blood of the circulatory system, which then transports oxygen to all body cells. It also removes carbon dioxide waste that the circulatory system carries away from cells.
2. Muscles are important because they allow body movement, support posture, help internal organs function (like the heart and digestive muscles), and generate body heat.
3. The skeletal system is important because it provides a structural framework for the body, works with muscles to enable movement, produces red and white blood cells, and stores calcium to support bodily processes.
