Question

Describe how the respiratory system and circulatory system work together to supply the body with oxygen and to remove waste from the body.

Answer 1

The Circulatory system pumps blood around the body, and the respiratory system facilitates the gas exchange that keeps the blood fresh. The heart is connected to the lungs via the pulmonary arteries and veins.

The circulatory and respiratory systems work together to deliver oxygen and other important nutrients to every cell in our bodies. All of our body cell require oxygen to conduct cellular respiration. In this process, oxygen burns the nutrients from foods w eat, providing energy for the cells. The respiratory system is responsible for bringing oxygen into the body and removing waste gasses.

Answer 2

The circulatory system helps in pumping of blood to all parts of the body. The circulatory system is connected to the respiratory system by pulmonary arteries and veins. The lungs help in gaseous exchange and oxygenating the blood when the blood is returned to it from the heart.

Further Explanation:

The circulatory system of the human body is that system which is necessary for the blood circulationto each cell of the body. Blood is the carrier of oxygen toeach cellof the body. Different blood vessels of the heart have different functions. The deoxygenated blood to the lungs from the heartis carried by the pulmonary arteries for oxygenation. The pulmonary vein carries deoxygenated blood to the heart from the lungs. Deoxygenated blood from the heart is pumped to all parts of the body by the aorta.

The Respiratory system of the human body is responsible for the exchange of gases. The deoxygenated blood from the heart is carried to the lungs via pulmonary arteries. The lungs have several sac-like partscalledalveoli. Alveoli responsible for the real exchange of gases. The deoxygenated blood is oxygenated by the process of diffusion and is returned to the heart. The cellular respirationtakes place presence of oxygen where oxygen burns the nutrients from the food that we eat to provide energy for the cells to work. All the metabolic activities are possible only because of the presence of oxygen. The respiratory system is responsible for removal of waste gases and purification of the deoxygenated blood.

Both these systems work together simultaneously and help in transport of oxygen throughout the body. Failure of any of these systems might lead to collapse of the body.
