to move nutrients to the individual cells of the body
It is called the hepatic portal circulation. A portal system is a system of blood vessels that begin in capillaries and end in capillaries without passing through the heart. The hepatic portal system begins in the capillaries in the digestive tract wall and ends in the capillaries in the liver.
There are many capillaries in your lungs, digestive system and muscles because each of these locations require blood to be transfered to individual cells snd capillaries are the smallest vessels that can do this.In your lungs capillaries connect to the alveoli and enable gas exchange within the body.In your digestive system capillaries enables food to be passed through the walls of the intestines.In your muscles capillaries deliver a fresh supply of oxygen to each cell and remove any bi-products enabling you to move sufficiently.
Capillaries are crucial to the digestive system because they facilitate the exchange of nutrients and waste products between the blood and the digestive organs. After food is broken down in the intestines, capillaries absorb essential nutrients, such as glucose and amino acids, and transport them to the bloodstream for distribution throughout the body. Additionally, they help remove waste products from the digestive process, ensuring efficient metabolism and overall health. This close network of capillaries supports the body's ability to utilize nutrients effectively.

Alveoli exchange Oxygen with blood in capillaries
Capillaries in the digestive system are tiny blood vessels that are part of the microcirculation, connecting arterioles and venules. They have thin walls composed of a single layer of endothelial cells, allowing for efficient exchange of nutrients, gases, and waste products between the blood and surrounding tissues. In the digestive system, capillaries are particularly dense in the villi of the small intestine, facilitating the absorption of nutrients from digested food into the bloodstream. This specialized structure ensures that nutrients are quickly delivered to cells throughout the body.
Some important questions to ask about the digestive system include: How does the digestive system break down food? What role do enzymes play in digestion? How does the digestive system absorb nutrients? What are common digestive disorders and how are they treated?
Lymph capillaries are small, thin-walled vessels that play a crucial role in the lymphatic system. They collect excess interstitial fluid, proteins, and waste products from tissues, which helps maintain fluid balance in the body. Once collected, this fluid, now called lymph, is transported to larger lymphatic vessels and eventually returned to the bloodstream. Additionally, lymph capillaries assist in the absorption of fats and fat-soluble vitamins from the digestive system.
digestive system throw the waste and dirt from the body and nutrients enters the circulatory system through capillaries.
It passes through the wall of the digestive system, then into the blood.
the nutrients absorbed in small intestine carried by the blood. the fats and few proteins escape through the capillaries and enters into the lymph which carry these to the lumphatic system.
