Question

How do the circulatory system, muscular system, and respiratory system work together to bring oxygen to the cells?

Answer 1

Hint: Different organs that are involved in similar functions makes the organ system that works together for carrying out respiration, breathing, excretion, circulation, etc.

Complete answer:
1)The circulatory system comprises the heart and different blood vessels, the heart consists of different chambers that are involved in purification or oxygenation of the deoxygenated impure blood that comes from the body. Hence the circulatory system helps in the oxygenation of blood which is then transferred to all the cells of the body.
2)The muscular system also works to bring oxygen to the cells, as the different muscles attached to the hearts are involved in the contraction and relaxation of heart chambers and blood vessels that help in oxygenation and purification of blood.
3)The diaphragm is also regulated by muscles that help in enlargement by stretching of lungs This increases the volume of lungs that helps the oxygen to enter the lungs and the oxygen is also diffused among different capillaries that is facilitated by the respiratory system.
4)The circulatory, respiratory, and muscular system works together to bring oxygen to the impure deoxygenated blood after which the blood is transported to all the cells, tissues, and organs of the body.

Note: The most important system among the circulatory system, respiratory system, and muscular system brings oxygen to the cells in the circulatory system because the function of the muscular system is to facilitate the entry of oxygen into the blood by stretching and relaxing different muscles and the respiratory system also supplies oxygen to the blood by diffusion. The circulatory system is the main system that transports the oxygenated blood to the cells.
