What factors affect waves?

Wave height is affected by wind speed, wind duration (or how long the wind blows), and fetch, which is the distance over water that the wind blows in a single direction. If wind speed is slow, only small waves result, regardless of wind duration or fetch.

What creates a wave in physics?

It is for this reason, that a wave is said to involve the movement of a disturbance without the movement of matter. The particles of the medium (water molecules, slinky coils, stadium fans) simply vibrate about a fixed position as the pattern of the disturbance moves from one location to another location.

What does the villi absorb?

Villi that line the walls of the small intestine absorb nutrients into capillaries of the circulatory system and lacteals of the lymphatic system. Villi contain capillary beds, as well as lymphatic vessels called lacteals. Fatty acids absorbed from broken-down chyme pass into the lacteals.

What will happen if there is no villi in the small intestine?

If you don’t have functioning intestinal villi, you can become malnourished or even starve, regardless of how much food you eat, because your body simply isn’t able to absorb and make use of that food.

What are villi how are they important in absorption?

The function of the plicae circulares, the villi, and the microvilli is to increase the amount of surface area available for the absorption of nutrients. The epithelial cells of the villi transport nutrients from the lumen of the intestine into these capillaries ( amino acids and carbohydrates) and lacteals (lipids).

What is the main function of villi?

The villi of the small intestine project into the intestinal cavity, greatly increasing the surface area for food absorption and adding digestive secretions.

What are the two functions of villi?

Functions. Their function is to increase the surface area of the small intestinal wall for absorption of the digested food. These projections absorb the protein molecules and help in the transfer of the proteins to all cells and tissues.

What is the function of villi where are they present?

Question 5 Solution 5: Villi are small finger-like projections found inside the inner walls of the small intestine. They v increase the surface area for absorption of the digested food.

What is Lacteal and its function?

A lacteal is a lymphatic capillary that absorbs dietary fats in the villi of the small intestine. Triglycerides are emulsified by bile and hydrolyzed by the enzyme lipase, resulting in a mixture of fatty acids, di- and monoglycerides. At this point, the fats are in the bloodstream in the form of chylomicrons.

Where is Lacteal found?

In the intestine, lymphatic capillaries, or lacteals, are located exclusively in intestinal villi, whereas collecting lymphatic vessels are present in the mesentery. 7 The term gut lymphatics used throughout this review refers to both lacteals in the intestinal villi and lymphatic vessels in the submucosa.

What do you mean by Lacteal?

Lacteal, one of the lymphatic vessels that serve the small intestine and, after a meal, become white from the minute fat globules that their lymph contains (see chyle).
