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.
Answer:
Explanation:
by the environment around us, we breath
The inaccurate statements are:
- Warm, moist air goes up the mountain on its leeward side, where its water content condenses to precipitate as rain or snow;
- This side is called the windward side and, compared with the leeward side, receives hardly any rainfall;
In the description, the windward and the leeward sides of the mountain are mistaken, or rather have switched positions.
The windward side is the side where the warm, moist air where the water condensates and results in rainfall or snow. Thus this is the side of the mountain that is wetter and is covered with denser vegetation.
The leeward side is the side that doesn't receive warm and moist air, and the amount of precipitation is usually very low. This makes the leeward side very dry in most cases, and very often it is the reason for the formation of arid and semi-arid areas.
