Yes, the circulatory system is responsible for carrying nutrients such as oxygen, glucose, amino acids, and fatty acids to the cells. These nutrients are transported in the blood and distributed to various tissues and organs to support their metabolic functions.
Oxygen is transported first by air down the trachea and then transform to the hemoglobin of the blood to the cells. This is the pathway of oxygen in the human system.
The circulatory system is responsible for transporting blood throughout the human body. It consists of the heart, blood vessels, and blood itself. It delivers oxygen, nutrients, and hormones to cells, and removes waste products.
Its not digested as it is easily small enough to be absorbed directly. It Moves through channels called aquaporins that are present on the intestinal villus cells following the osmotic gradient set by sodium.
Because it is in a form which is already digested e.g honey. Honey is already digested by bees so it is far more easier for the human digestive system to absorb.
The cells hereditary system is the DNA of the human body.
Oxygen is transported in the human body by binding to hemoglobin in red blood cells. Hemoglobin carries oxygen from the lungs to tissues in the body, where it is released for cells to use in cellular respiration. The carbon dioxide produced is then transported back to the lungs to be exhaled.
Cellulose fiber is not digested by the human digestive system, but also bear in mind that digestion does not work with 100% efficiency, so even nutrients that we digest are not completely digested. Anything not digested will, in due course, be eliminated in the form of a bowel movement.
There are so many structures in the digestive system because the the food can be digested very easily and broken down into soluble food material and absorbed by the finger like projections villi and absorbed into the human cells.

Human cheek cells are part of the integumentary system, which includes the skin and its associated structures. Cheek cells are found on the surface of the skin lining the inside of the cheeks.
