Which of the following is NOT true about the absorption of fats?
babunello [35]

Answer:

The best choice from the answer options for the question: Which of the following is NOT true about absorption of fats, would be: C: The chylomicrons enter the blood in the villi capillaries.

Explanation:

Because of the characteristics of fatty acids, and fats in general, they are not able to either pass the intestinal enterocytes, and enter the bloodstream, as easily as glucose, or other molecules, can. Instead, they first must be passed into the enterocytes, the intenstines´ cells, by their combination with bile. Once inside the intestine, the enterocytes take up the fats and combines them with lipoproteins and cholesterol in order to create the chylomicrons. But before these chylomicrons can make their way to the blood, first they must be taken up by the lymphatic vessels present in the villus of the intestinal epithelium, not the blood capillaries. It will be the lymphatic system which will be reponsible for passing the fats to the bloodstream, who will then distribute them to the appropriate cells in the body as energy is required. Or they will be taken for storage by the liver.

What is the function of a circulatory system? a) It brings a transport liquid into close contact with all cells in the body. b)
Tomtit [17]

Answer:

The correct answer is a) It brings a transport liquid into close contact with all cells in the body.

Explanation:

The circulatory system helps in bringing the blood which is a transport liquid in close contact with the cells present in our body. This helps in gas exchange between cells and blood. The circulation of blood in the body occurs by the pumping of blood by the heart into arteries, veins, and capillaries.

This circulation of blood plays many other vital functions like transport of nutrients to the cells, transport of waste products from the cell to outside the body, transport of hormones, maintenance of body temperature, etc.  

So all these processes become possible when transport liquid comes in contact with the cells. Therefore the right answer is a.
