Complementary Body Systems
The Digestive system supports the Circulatory system through the intake of nutrients. Food is taken down to the stomach by the esophagus.The stomach breaks down proteins and other food.The food is sent to the small intestine where most of the absorption of nutrients take place.
The nutrients that taken then they are then diffused through the walls of the small intestine and into the bloodstream. Thanks to the nutrients in the blood, the heart can pump oxygenated and nutrient rich blood to the body so that organs, tissues and muscles can receive proper nourishment.
Also there the Respiratory system contributes to the Circulatory system (and the rest of the body) by the transfer of oxygen and carbon dioxide. When you inhale, a muscle known as the diaphragm moves down to draw oxygen into the lungs. The oxygen enters the windpipe, or the trachea which branches into bronchus which branches into bronchioles. At the end of the bronchioles are small sacs known as alveoli which are surrounded by capillaries. Alveoli are responsible for the exchange in carbon dioxide for oxygen. Blood that was pumped to the lungs by the heart through the pulmonary artery picks up the oxygen that the lungs inhale and releases the oxygen into the blood flow through the pulmonary vein and back to the heart. The intervention of the Respiratory system is what causes oxygen enriched blood to be pumped to all cells of the body so that cellular respiration can occur for energy.
