What can transport monoglycerides and long-chain fatty acids through the intestine to the microvilli of cells?
Chylomicrons
What else can I help you with?
Are fats absorbed by active transport or passive transport?
Fats are absorbed mainly by passive transport in the small intestine. This process involves the diffusion of fatty acids and monoglycerides across the intestinal epithelium and into the bloodstream without the need for energy input.
What is the role the microvilli?
Microvilli are finger-like projections on the surface of cells that increase the cell's surface area for absorption of nutrients. They are found in cells of the small intestine, kidney, and other tissues involved in absorption or secretion. Microvilli also contain enzymes and transport proteins that aid in nutrient absorption.
Water and certain vitamins are absorbed here from the undigested food?
The small intestine is responsible for absorbing water and vitamins from undigested food through its large surface area and specialized cells such as villi and microvilli. Villi increase the absorptive surface area, while microvilli on the surface of enterocytes further enhance nutrient absorption by increasing surface area and facilitating transport.
How do the microvilli help in the absorption of nutrients?
Microvilli increase the surface area of the small intestine, facilitating the absorption of nutrients by providing more space for nutrients to be absorbed into the bloodstream. They also contain enzymes that help break down nutrients into smaller molecules for easy absorption. Additionally, microvilli have transport proteins that assist in moving the absorbed nutrients across the intestinal lining and into the bloodstream.
What plasma membrane extensions create the most surface area for the cell?
Microvilli are plasma membrane extensions that create the most surface area for the cell. These finger-like projections are found in cells involved in absorption, such as the cells lining the small intestine, and increase the cell's ability to transport nutrients.

What is the difference between a villi and microvilli?
Both are found inside the small intestine, are microscopic, and are used to increase the surface area of the small intestine. Villi are tiny microscopic folds in the small intestine lining. Microvilli are little hairlike projections from individual epithelial cells of the small intestine. They have capillaries and a lacteal that lead to the circulatory and lymph systems to transport nutrients that are absorbed.
What are the major roles of the villi and microvilli in the small intestine?
Villi are responsible for absorbing nutrients from the small intestine into the bloodstream, for transport to the liver and other cells. In order to increase the amount of nutrients taken into the bloodstream, each villus itself has dozens of microvilli, to increase greatly the surface area.
Which part of the alimentary canal does absorption takes place?
In humans absorption takes place in the small intestines. In the small intestines are tiny structures called villi. Each villi has microvilli. These villi increase the surface area for absorption. Inside a microvilli, there is a network of capillaries and lacteals. Lacteals absorb amino acids and transport it to the liver via the subclavian vein which leads into the back of the neck, from there it gets distributed to the rest of the body. Back to the microvilli. The microvilli contains capillaries which absorb fatty acids and glycerols. These are transported to the liver via the heptic portal vein.

Can long-chain fatty acids be absorbed directly into the blood?
No, long-chain fatty acids are broken down into smaller molecules called monoglycerides and free fatty acids in the small intestine before they can be absorbed into the bloodstream. They are then reassembled into triglycerides and packaged into chylomicrons for transport.
Texture of Inner lining of small intestine?
The inner lining of the small intestine is characterized by its numerous finger-like projections called villi and microvilli that increase the surface area available for nutrient absorption. Additionally, the lining contains specialized cells such as enterocytes, goblet cells, and Paneth cells that help with digestion and absorption of nutrients. The small intestine lining also has a rich blood and lymphatic supply to transport absorbed nutrients to the rest of the body.
What does the intestine of a mollusk do?
transport food
How are fats absorbed in the small intestine?
Fats are broken down into fatty acids and monoglycerides by enzymes in the small intestine. These small molecules are then absorbed into the intestinal lining and formed into larger structures called chylomicrons. These chylomicrons are released into the lymphatic system and eventually transported to the bloodstream for distribution to the body's cells.
