The mouth, you eat food with them in.
Nutrients are the substance in foods that the body needs to promote growth and repair body, tissues, and to get energy. The body needs nutrients including protein to regulate bodily functions.

"digestive"
Oxygen plays a massive role in the human body. Oxygen is responsible for delivering nutrients to the cells in the human body.

your body
Nutrients enter the body through the digestive system, primarily in the small intestine. They are absorbed into the bloodstream and transported to cells throughout the body to support overall health and well-being.
Nutrients from the digestive system enter the circulatory system. From there, they are transported to all body cells.
Nutrients enter the body through a process called absorption, where they are taken in by the cells for energy and other functions. Waste leaves the body through a process called excretion, where it is removed from the body to maintain a healthy internal environment.
That function is done by the liver
The nutrients and O do not come from the plasma to the body cells. They came from the red blood cells that deliver them (or so I thought). They then enter the capillaries and give the nutrients and O to the other cells and get the waste products like CO2.
The capillaries are the site of diffusion of wastes, oxygen, and nutrients. This allows these materials to enter and leave body tissues.
Absorption is the process that takes nutrients through the small intestine wall. These nutrients then enter the circulatory system, which carries the nutrients to all body cells.
Examples of substances that enter the body include nutrients from food, oxygen from the air we breathe, and medications. Substances that leave the body include carbon dioxide when we exhale, waste products such as urine and sweat, and toxins removed by the liver.
The digestive system extracts nutrients from food and releases them into the bloodstream for transport to cells around the body. Nutrient absorption primarily takes place in the small intestine, where nutrients are absorbed through the intestinal wall and enter the bloodstream through tiny blood vessels called capillaries.
Your body is composed entirely of nutrients, or of substances that were made from nutrients.
