How Does The Circulatory System Interact With The Digestive System | How to Reset Our Digestive System?

The circulatory system transports blood in the human body. Blood supplies water and nutrients from the digestive system and oxygen from the respiratory system to all cells in the human body. Blood also transports wastes from body cells to the organs that remove wastes.


The circulatory system, the heart, pumps blood. The heart is a fist- muscle divided into two upper chambers called atria, and two lower chambers called ventricles.

Oxygen-poor blood from the body begins on the right side of the heart. Next, the right atrium or right ventricle pumps oxygen- and poor blood to the lungs.

While in the lungs, the blood taking oxygen gas and releases excess carbon dioxide gas it has taken away from body cells. 

The oxygen-rich blood passes to the left side of the heart from the lungs. The left atrium and left ventricle pump oxygen-rich blood to the rest of the body. 

When it reaches body cells, the oxygen-rich blood gives up its nutrition, and oxygen picks up carbon dioxide gas. So the blood back to the right atrium, and the cycle continues.

There are three blood vessels inside the body: arteries, capillaries, and veins. In general, arteries carry oxygen and blood away from the heart.

How does the circulatory system interact with the digestive system

Does not matter what you eat; our body’s digestive system processes everything that goes into your mouth. Processes occur within the digestive system: digestion, elimination, and absorption. 

  • Digestion is the breakdown of food, which are molecules that your body’s cells can use.
  • Absorption is the nutrients from the digestive system into the bloodstream, where they can be given to all parts of the body.
  • Elimination is the removal of undigested supply from the body.

It happens in a series of organs called the digestive tract. 

Digestion starts you put food in your mouth. Chewing breaks, and smaller pieces and enzymes in your saliva help to break down food chemically. In addition, smooth muscle in the digestive tract moves food into the digestive system.

Partially digested food passes from the stomach into the small intestine, where absorption happens. 

Digested nutrients or water pass through the walls of the small intestine and the bloodstream. Likewise, waste materials continue through the small intestine and move into the large intestine. 

However, food does not move through the liver, gallbladder, and pancreas, the main parts of the digestive system. 

Three organs digest in the small intestine. The liver is the largest physical organ of the body and holds many functions.  

Excess bile makes the liver is stored in a small gland called the gallbladder. Then, it is releases bile into the small intestine as required. 

The pancreas produces digestive enzymes. It is the pancreas are proteins that speed up effects. The enzymes the pancreas produces help break down proteins and carbohydrates, and fats in the small intestine.

Processes within cells result in waste products. It is waste products must be removed from your body to maintain your systems in balance. The excretory system is the removes liquid, gas, and solid wastes from the body.

How to reset your digestive system?

Investigation shows that the bacteria living in our intestinal track could have more power on our health than we realize, says Lifestyle and Disease Management Center.

The microbiome inside our bodies is still evolving, but analysis has linked changes in intestinal bacteria with mental illnesses, autoimmune diseases, and more.

Recent studies have also shown that the bacteria in our bellies may be controlling which foods we need. So that’s right—your craving for potato chips may not be all in your energy after all.

Research recommends that our diet, as other factors stress and antibiotic use, affects whether our intestinal tract is “good” or “bad” bacteria.

And it takes dietary changes to a whole new level—in addition, to provide the nutrients our bodies want, the food we eat is feeding our microbiome, which could directly affect resilience against infection, and high risk for a host of other illnesses.

What constitutes an optimal bacteria is also still a question, but most studies agree that a diet of lots of fiber helps promote a more healthy stomach microbiome.

The good guys among your stomach bacteria thrive on all kinds of fiber, cellulose, the insoluble fiber that gives vegetables their think celery, or broccoli stalks. Another kind of fiber, called fructan, acts as a prebiotic and helps good bacteria to grow.

Foods to help digestion

  • Asparagus, especially the stalk
  • Garlic
  • Wheat bran
  • Nectarines
  • Watermelons
  • Bananas
  • Pears
  • Chicory roots
  • Leeks
  • White onions
  • Raspberries
  • Artichokes
  • Cooked beans

Remember that when you make a food change, even a healthy digestive system requires time to adjust. Adding fruits and vegetables can help avoid intestinal distress, such as gas and bloating.


A healthy, low-stress lifestyle emphasizing exercise, sleep, and plant-based foods are the best way to maintain a healthy stomach.

But if you’re only one thing: Change your diet to include more whole foods and vegetables.

While your microbiome may change immediately with what you eat, there are no quick fixes or overnight miracle workers for a healthy stomach. Instead, it’s about sticking to the small changes that add up.
