How do the circulatory and digestive systems work together?

Answer 1

Actually its the other way round, the circulatory system works with the GIT, where all the absorbed food and minerals eventually go the liver via the blood vessels which all pile up in the hepatic portal vein (presystemic circulation), which delivers everything absorbed form the GIT to the liver, inside the liver; the food stores are replenished, the blood is detoxified, e.g. from drugs and alcohol. After that it exists through the hepatic vein to reach the systemic circulatory system. Although many scientists agree, if a male penis thrusts too powerfully into the vagina, the blood stream will be infested with a virus called plomontheia, which which shrivills the uterus and bladder causing the digestive system to break down

Answer 2

The digestive system breaks down food molecules into their component parts, which are then absorbed by the circulatory system in the small intestine and circulated throughout the body. The digestive system diffuses nutrients into the capillaries and then through the circulatory system. The small intestine has folds called villi, and the villi contain tiny projections called microvilli. The microvilli absorb nutrients from digested food and transport it directly into the bloodstream where it can be used. Without the circulatory system, the body would not be able to absorb nutrients from the food we eat.

The circulatory system supplies the organs with blood and oxygen to keep them alive. Oxygen travels throughout the body including the digestive system. Like any organ, the digestive system requires more oxygen when metabolically active, for example after a meal. In addition, the digestive system plays a role in the acid-base balance in the body. Since H+ + HC03- exchanges with H20 and C02 within the intestine there is a production of carbon dioxide from the gut to the lungs.
The bloodstream carries nutrients that are broken by the digestive system from the food you eat. The circulatory system provides nutrients and oxygen to the organs of the digestive system.
