I believe the correct answer is that they all are connected to one another.

<h2>Explanation:</h2>

The digestive system is optimized in order to ensure there is minimal wastage of the much needed nutrients obtained after the process of digestion. One of this optimization is witnessed in the small intestines (ileum). The following are ways the small intestines are optimized:

<h2>Further Explanation:</h2>

The ileum is very long and convoluted in order to slow down the movement of food through it which in the end ensures that absorption takes place effectively since this is the site of absorption of food that has been chemically and mechanically broken down in the mouth, stomach and duodenum.
It has numerous epithelial cells that have been convoluted into troughs and crests forming pits that maximize absorption of food in the small intestines. The epithelial cells of the small intestines also specialize into cells called goblet cells that produce mucus which ensures that the food in the intestines is well lubricated as it goes through it.
The epithelium is also thin enough to ensure that nutrients are absorbed easily into the neighbouring capillary beds through the cell junctions.
The ileum is well vascularized by capillary fenestrations that pick up the already digested food and then the capillaries distribute food to the rest of the body through the circulatory system.
Glucose is part of food that is produced during the process of digestion and diffuses through the epithelium of the small intestines into the capillary bed and to the rest of the body through the circulatory system. In the body, cells convert the energy stored in glucose molecules into ATP via cellular respiraation that the body uses to perform daily activities such as movement.

The small intestine comprises of an external layer called epithelium, from which originates microvilli that are the extensions of the small intestine, which projects in the form of tubes and their prime activity is to give a large surface area of absorption to obtain the majority of nutrients.

The nutrients obtained by the microvilli are included into the circulatory system, the prime activity of the circulatory system is to carry different constituents like amino acids, glucose, proteins, and other complex components like oxygen and hormones. It also helps in the conduction of various metabolic wastes discharged from the tissues.

The circulatory system comprises many kinds of capillaries, the most essential of which are arterial capillaries, venous capillaries, and fenestrated capillaries. The fenestrated capillaries are characterized by the pores present in the endothelial cells, which permits small molecules and restricted concentrations of proteins to pass through.

The most essential nutrient carried during the whole process is glucose. It has been considered as the prime source of energy, which is further hydrolyzed to produce two molecules of ATP. The ATP is known as the energy currency of the cell as it provides energy for different cellular and metabolic procedures essential for life.
