How the Organs Get Nutrients:

The organs in the human body collect nutrients through a complex process that involves several systems. The digestive system breaks down food into smaller molecules that can be absorbed by the villi in the small intestine. The nutrients are then transported to the liver, by way of the capillaries, which travel everywhere in the body where they are processed and distributed to the rest of the body. The circulatory system plays a crucial role in this process by carrying the nutrients to the cells that need them. The kidneys filter waste products from the blood and excrete them in urine, while the lungs remove carbon dioxide and other gases from the body.
