Which statement best describes the breakdown of food in the digestive system Brainly?

Which statement best describes the breakdown of food in the digestive system Brainly?

Answer: The correct answer is option B: Carbohydrate digestion starts in the mouth and protein digestion starts in the stomach.

What does the digestive system break down food into?

The digestive system converts the foods we eat into their simplest forms, like glucose (sugars), amino acids (that make up protein) or fatty acids (that make up fats). The broken-down food is then absorbed into the bloodstream from the small intestine and the nutrients are carried to each cell in the body.

What are 3 major organs of the digestive system?

The liver, pancreas, and gallbladder are the solid organs of the digestive system. The small intestine has three parts. The first part is called the duodenum. The jejunum is in the middle and the ileum is at the end.

What organs are chemical digestion?

Most chemical digestion takes place in the duodenum by chemicals secreted by the liver, pancreas and small intestine. The other two sections of the small intestine, the jejunum and the ileum, absorb food molecules by way of the villi directly into the blood stream.

What are some examples of chemical digestion?

Chemical digestion breaks down different nutrients, such as proteins, carbohydrates, and fats, into even smaller parts:

• Fats break down into fatty acids and monoglycerides.
• Nucleic acids break down into nucleotides.
• Polysaccharides, or carbohydrate sugars, break down into monosaccharides.

What chemical digestion occurs in the stomach?

Protein digestion occurs in the stomach and the duodenum through the action of three primary enzymes: Pepsin, secreted by the stomach. Trypsin, secreted by the pancreas.

What is digestion absorption?

Absorption refers to the movement of nutrients, water and electrolytes from the lumen of the small intestine into the cell, then into the blood. In this article, we will look at the digestion and absorption of carbohydrates, protein and lipids.

Where does absorption begin in the digestive system?

Absorption begins in the stomach with simple molecules like water and alcohol being absorbed directly into the bloodstream. Most absorption takes place in the walls of the small intestine, which are densely folded to maximize the surface area in contact with digested food.

Where is absorption in the digestive system?

The small intestine is the part of the gastrointestinal tract between the stomach and the large intestine where much of the digestion of food takes place. The primary function of the small intestine is the absorption of nutrients and minerals found in food.

What is the process of digestion step by step?

The processes of digestion include six activities: ingestion, propulsion, mechanical or physical digestion, chemical digestion, absorption, and defecation. The first of these processes, ingestion, refers to the entry of food into the alimentary canal through the mouth.

How digestion works step by step?

Your digestive system, from beginning … to end

1. Step 1: Mouth. To more easily absorb different foods, your saliva helps break down what you’re eating and turn it into chemicals called enzymes.
2. Step 2: Esophagus.
3. Step 3: Stomach.
4. Step 4: Small Intestine.
5. Step 5: Large Intestine, Colon, Rectum and Anus.

What’s the process of absorption?

The process of absorption means that a substance captures and transforms energy. The absorbent distributes the material it captures throughout whole and adsorbent only distributes it through the surface. The process of gas or liquid which penetrate into the body of adsorbent is commonly known as absorption.

What is absorption system?

: a refrigerating system in which refrigeration is effected by the expansion in evaporating coils of liquid ammonia into gas which is then absorbed by water and used again after the water is evaporated.

Where are absorption chillers used?

Absorption chillers are being used around the globe as an efficient solution wherever waste heat recovery or a low-cost thermal driving heat source are available, especially as part of a natural-gas or a combined heat and power (CHP) system.

How do absorption chillers work?

In short, the absorption chiller chills water via sudden change of pressure. When the water heats up in the generator, the air pressure is high. Water releases the heat and becomes vapor. Then, a pipe leads the vapor to the evaporator, where the air pressure is low.

Which of the following is absorption unit?

Explanation: Cyclone collector, Gravitation settling chamber and Dynamic precipitator are used to remove particulate matter, whereas Plate tower is used to remove gaseous matter and is an absorption unit.

What is VARS system?

Vapour Absorption Refrigeration Systems (VARS) belong to the class of vapour cycles similar to vapour compression refrigeration systems. Since these systems run on low-grade thermal energy, they are preferred when low-grade energy such as waste heat or solar energy is available.

What is the function of absorber and rectifier?

6) Rectifier or the reflex condenser: The rectifier is a sort of the heat exchanger cooled by the water, which is also used for cooling the condenser. Due to cooling the remaining water vapor mixed with the ammonia refrigerant also gets condensed along with some particles of ammonia.

What is Vapour absorption cycle?

Simple Vapour Absorption Cycle: The most commonly used fluids in the absorption system are water as absorbent and ammonia as refrigerant. The vapour from the evaporator is allowed to be mixed and absorbed in the absorber.

What is simple Vapour absorption system?

The simple vapour absorption system, as shown in fig. 2.1, consists of an absorber, a pump, a generator and a pressure reducing value to replace the compressor of vapour compression system. The other components of the system are condenser, receiver, expansion value and evaporator as in the vapour compression system.

What is simple Vapour compression cycle?

Simple vapour compression cycle is a system where the suitable working substance is used, called as a refrigerant. It evaporates and condenses at pressure and temperature closes to atmospheric conditions. The refrigerant used is carbon dioxide, ammonia etc.

How does Vapour absorption machine works?

The vapor gets readily absorbed into the absorbent, due to its strong affinity for the refrigerant. The cooling water flowing through the cooling coils within the absorber absorbs the heat load from the evaporator and, unavoidably, some of the residual heat from the concentrated solution.
