MICROANATOMY

Detailed explanation-1: -Broadly, here’s how the respiratory system interacts with the digestive system: Breathing provides oxygen to help your digestive tract function, and digestion provides nutrients to fuel your respiratory system, according to Texas A&M University.

Detailed explanation-2: -Your respiratory system takes in oxygen from the air. It also gets rid of carbon dioxide. Your digestive system absorbs water and nutrients from the food you eat. Your circulatory system carries oxygen, water, and nutrients to cells throughout your body.

Detailed explanation-3: -The respiratory system is primarily used to transport air, while the digestive system is used to transport fluids (such as water) and solids (such as food particulates). The respiratory and the digestive systems share the region of the mouth and upper throat, where air, fluids, and solids can be mixed.

Detailed explanation-4: -The glucose needed for cellular respiration comes from the digestive system via the cardiovascular system. The oxygen needed for cellular respiration comes from the respiratory system also via the cardiovascular system. The carbon dioxide produced in cellular respiration leaves the body by the opposite route.

Detailed explanation-5: -The heart, blood and blood vessels work together to service the cells of the body. Using the network of arteries, veins and capillaries, blood carries carbon dioxide to the lungs (for exhalation) and picks up oxygen. From the small intestine, the blood gathers food nutrients and delivers them to every cell.
