How do the digestive circulatory and respiratory systems serve a body cell in big toe?

Digestive system:

- The digestive system provides nutrients and energy to the body cell in the big toe.

- The process begins with the ingestion of food, which is broken down in the mouth by teeth and saliva.

- The food then travels down the esophagus to the stomach, where it is further broken down by stomach acids and enzymes.

- The partially digested food then enters the small intestine, where it is further broken down by enzymes from the pancreas and bile from the liver.

- The nutrients from the food are then absorbed into the bloodstream through the walls of the small intestine.

- Undigested food moves into the large intestine, where water and electrolytes are absorbed, and the remaining waste is eliminated as feces.

Circulatory system:

- The circulatory system transports the nutrients, oxygen, and hormones from the digestive system to the body cell in the big toe.

- The heart pumps oxygenated blood from the lungs through the arteries to the capillaries, which are small blood vessels that surround the body's cells.

- The nutrients and oxygen from the blood diffuse into the body cell, while the waste products of cellular metabolism diffuse out of the cell and into the capillaries.

- The deoxygenated blood then flows back to the heart through the veins.

Respiratory system

- The respiratory system provides oxygen to the body cell in the big toe and removes carbon dioxide, a waste product of cellular metabolism.

- During inhalation, air is drawn into the lungs through the nose or mouth.

- The air travels down the trachea and into the bronchi, which are the smaller branches of the trachea.

- The bronchi lead to the alveoli, which are tiny sacs in the lungs where the exchange of oxygen and carbon dioxide takes place.

- Oxygen diffuses from the alveoli into the bloodstream through the capillaries, while carbon dioxide diffuses out of the bloodstream and into the alveoli.

- During exhalation, the carbon dioxide-rich air is expelled from the lungs through the nose or mouth.
