How do the respiratory system and circulatory system work together?

Answer 1

The circulatory system transports oxygen through the body and the respiratory system supplies that oxygen. The respiratory system performs a process known as gas exchange that releases carbon dioxide from the body and brings in oxygen. This occurs in the lungs, and the circulatory system then transports the oxygen to tissues that used internal respiration to burn fuel in the form of ATP (adenosine triphosphate) for energy, thus creating more carbon dioxide. The alveoil transport oxygen from the lungs into the circulatory system. You breathe in oxygen into your lungs. The oxygen diffuses across the thin walls of the alveoli in the lungs and the thin walls of the blood vessels in the lungs into the blood stream. Here it attaches to the hemoglobin molecules inside red blood cells. The red blood cells are carried by the blood vessels to all parts of the body. The hemoglobin releases oxygen in the periphery, and picks up carbon dioxide (CO2). The CO2 attached to the hemoglobin molecules in the red blood cells is then transported to the lungs, where it diffuses across the walls into the alveoli, and is breathed out.

Respiratory System - GETS the oxygen needed for cells

Circulatory System - DELIVERS the oxygen to cells
The respiratory system is related to your circulatory system because your respiratory system helps you breathe in oxygen. Your blood is pumped to the lungs to pick up oxygen, then flows back to the heart to be pumped to the rest of your body to meet the needs of your body. I hope that helped! :P
