Which of the following is transported via facilitated diffusion in the small intestine?

Which of the following is transported via facilitated diffusion in the small intestine?

Small fat-soluble molecules, such as free fatty acids and fat-soluble vitamins, are absorbed through facilitated diffusion in the small intestine. Amino acids are absorbed through the process known as active transport.

What is the physical and chemical breakdown of complex nutrients into simpler water soluble substances the body can use?

Digestion is the mechanical and chemical break down of food into small organic fragments. In chemical digestion, enzymes break down food into the small molecules the body can use.

What are two advantages of a longer alimentary canal for processing plant material that is difficult to digest?

What are two advantages of a longer alimentary canal for processing plant material that is difficult to digest? The increased time for transit through the alimentary canal allows for more extensive processing, and the increased surface of the canal area provides greater opportunity for absorption.

Which mechanism for absorption is described as requiring energy and a carrier molecule?

True – Active transport, which requires the combination of energy and a carrier to promote absorption against a concentration gradient, is the process by which nutrients such as amino acids and glucose are absorbed.

How are the nutrients absorbed in the small intestine?

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.

How do nutrients absorbed in the small intestine travel to the individual cells of the human body?

The small intestine Nutrients are absorbed from the ileum, which is lined with millions of finger-like projections called villi. Each villus is connected to a mesh of capillaries. This is how nutrients pass into the bloodstream.

What is an advantage of an alimentary canal compared to a Gastrovascular cavity?

Gastrovascular cavity is functions in both digestion and distribution of nutrients that has a single opening. Alimentary Canal is (digestive tube with mouth and anus) allows for more complete digestion of food.

When a nutrient requires a carrier protein and energy in order to be absorbed this is called?

The correct answer is Active transport . The movement of molecules from one side of the cell membrane to the other side is achieved by…

Where does the absorption of nutrients take place in the digestive system?

The process of converting complex food particles into simpler substances in the presence of enzymes and acids secreted by different digestive organs. This process begins in the small intestine where most of the nutrients and minerals are absorbed. The excess water in the indigestible matter is absorbed by the large intestines.

Which is the first part of the digestive system to release food?

The pylorus releases a small amount of food at a time. Small intestine comes next in the order of digestive system. The digestion will continue even when your food has entered your duodenum, the first section of your small intestine.

What is the role of the digestive system in nutrition?

Human Digestive System and Nutrition involve the intake of food by an organism and its utilization for energy. This is a vital process which helps living beings to obtain their energy from various sources. The food which we eat undergoes much processing before the nutrients present in them are utilized to generate energy.

Where does food go after it enters the small intestine?

The food will enter the small intestine through a valve called the pylorus. The pylorus releases a small amount of food at a time. Small intestine comes next in the order of digestive system. The digestion will continue even when your food has entered your duodenum, the first section of your small intestine.
