Quick Answer: Which Of The Following Statements Is/are True Regarding Mechanical And/or Chemical Digestion?

How are mechanical and chemical digestion related?

Chemical and mechanical digestion are the two methods your body uses to break down foods. Mechanical digestion involves physical movement to make foods smaller. Chemical digestion uses enzymes to break down food.

What is the difference between mechanical and chemical digestion quizlet?

Mechanical digestion involves breaking the food up physically, and chemical is breaking it up using the body’s substances. It is responsible for most of the chemical digestion/absorption inside the body.

Which statement is true about digestion?

Digestion is a form of catabolic activity because it involves the breaking down of food into smaller sizes that can be absorbed as nutrients by the body while releasing energy through the process. The statement about digestion which is true is that, gastric juice helps to process food into chyme.

Which type of digestion happens in the stomach mechanical or chemical or both?

Proper digestion requires both mechanical and chemical digestion and occurs in the oral cavity, stomach, and small intestine.

What are the similarities and differences between mechanical and chemical digestion?

Mechanical digestion involves physically breaking the food into smaller pieces. Mechanical digestion begins in the mouth as the food is chewed. Chemical digestion involves breaking down the food into simpler nutrients that can be used by the cells. Chemical digestion begins in the mouth when food mixes with saliva.

What are examples of mechanical digestion?

Mechanical digestion is a purely physical process that does not change the chemical nature of the food. Instead, it makes the food smaller to increase both surface area and mobility. It includes mastication, or chewing, as well as tongue movements that help break food into smaller bits and mix food with saliva.

Where does mechanical and chemical digestion begin quizlet?

What is the difference between mechanical and chemical digestion where does each begin?

The main difference between mechanical and chemical digestion is that the mechanical breakdown of large food particles into small food particles occur in the mechanical digestion whereas the chemical breakdown of compounds with a high molecular weight into compounds with a low molecular weight occurs in the chemical

What is the difference between mechanical digestion and chemical digestion in the mouth?

Mechanical digestion is the mechanical breakdown of food into small particles. It occurs from mouth to stomach. Chemical digestion is the chemical breakdown of food into small chemical substances. It occurs from mouth to the intestine.

What are the three phases of gastric activity?

The process of gastric secretion can be divided into three phases ( cephalic, gastric, and intestinal ) that depend upon the primary mechanisms that cause the gastric mucosa to secrete gastric juice.

Where does digestion start?

Digestion begins in the mouth. The food is ground up by the teeth and moistened with saliva to make it easy to swallow. Saliva also has a special chemical, called an enzyme, which starts breaking down carbohydrates into sugars.

Where are enterocytes found?

Enterocytes, or intestinal absorptive cells, are simple columnar epithelial cells which line the inner surface of the small and large intestines. A glycocalyx surface coat contains digestive enzymes.

What are the two main processes of the digestive system?

Key Points Two important functions of the digestive system are digestion and absorption. The nutrients that come from food are derived from proteins, fats, carbohydrates, vitamins, and minerals. These complex macromolecules must be broken down and absorbed in the gastrointestinal (GI) tract.

What is digestion and absorption?

Digestion is the chemical breakdown of the ingested food into absorbable molecules. Absorption refers to the movement of nutrients, water and electrolytes from the lumen of the small intestine into the cell, then into the blood.
