Digestive system

Question 1

What is the Digestive system?

Answer 1

The process that breaks down breaks down food.

Question 2

What is the first part of digestion

Answer 2

Ingestion: It starts when you put food in your mouth. The process of eating involves chewing (mastication) and mixing food with saliva, which contains enzymes that begin breaking down carbohydrates.

Question 3

what is the second part of digestion

Answer 3

Propulsion: After chewing, the food is swallowed and travels down the esophagus through a process called peristalsis, which is a series of wave-like muscle contractions.

Question 4

what is the third par of digestion

Answer 4

Stomach: Once the food reaches the stomach, it’s mixed with gastric juices, including hydrochloric acid and pepsin, which help break down proteins and kill bacteria. The stomach churns the food into a semi-liquid substance called chyme.

Question 5

What is the fourth part of digestion

Answer 5

Small Intestine: The chyme moves into the small intestine, which is the primary site for digestion and nutrient absorption. The small intestine has three parts: the duodenum, jejunum, and ileum. Enzymes from the pancreas and bile from the liver further break down the chyme. Nutrients are absorbed through the walls of the small intestine into the bloodstream.

Question 6

what is the fifth part of digestion

Answer 6

Large Intestine: After passing through the small intestine, the remaining material enters the large intestine (colon). Here, water and salts are absorbed, and the material is formed into stool.

Question 7

What is the sixth part of digestion

Answer 7

Excretion: Finally, the waste products are expelled from the body through the rectum and anus during defecation.

Question 8

Mouth: Is teeth breaking down food into smaller pieces Mechanical or chemical

Answer 8

Mechanical

Question 9

Mouth: is Saliva softens, provides an enzyme to start breaking nutrients Mechanical or chemical.

Answer 9

Chemical

Question 10

Oesophagus: Is Food that is transported to stomach by wave like contractions
(Peristalsis) Mechanical or chemical.

Answer 10

Mechanical

Question 11

Stomach: Is acid that acts on food to break down nutrients mechanical or chemical

Answer 11

Chemical

Question 12

Stomach: is Churning Mechanical or chemical.

Answer 12

Mechanical

Question 13

Small intestine: is enzymes acting to convert all nutrients get absorbed into blood stem Mechanical or Chemical.

Answer 13

Chemical

Question 14

what is Mechanical Digestion.

Answer 14

Mechanical digestion: Is a physical change because no new substances are made.
Example: Is when the food is sliced, torn and crushed by your teeth, breaking it down into smaller pieces.

Question 15

What is Chemical Digestion.

Answer 15

Chemical digestion: Is a Chemical change because new substances are produced.
Example: The large complex substances in the food are broken down into simpler chemicals by saliva in your mouth and gastric juice in your stomach. This produces new, smaller chemicals that the body can absorb.

Question 16

what is the difference between Mechanical and chemical digestion.

Answer 16

Mechanical digestion involves physical movement to make foods smaller. Chemical digestion uses enzymes to break down food.

Question 17

what is the digestive system?

Answer 17

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)

Question 18

What are the seven main parts of the digestive system.

Answer 18

mouth, esophagus, stomach, small intestine, large intestine and anus.

Question 19

What is the mouth

Answer 19

The digestive system starts in your mouth.
Ingestion: The mouth is where food and liquids enter the digestive system. Teeth help break down food into smaller pieces, and saliva starts the process of digestion.

Question 20

what is the esophagus

Answer 20

It transports foods and liquid. The esophagus does not participate in digestion, its role is to move food into the stomach.

Question 21

what is the stomach

Answer 21

An organ with strong muscular walls, the stomach holds the food and mixes it with acid and enzymes that continue to break the food down into a liquid or paste.

Question 22

what is the small intestine

Answer 22

The small intestine has three parts: the duodenum, jejunum, and ileum. It helps to further digest food coming from the stomach. It absorbs nutrients (vitamins, minerals, carbohydrates, fats, proteins) and water from food so they can be used by the body.

Question 23

what are glands

Answer 23

Glands in your mouth pump out saliva? store saliva

Question 24

what happens before you have even eaten food.

Answer 24

glands inside your mouth start to pump out saliva, before even eat food.

Question 25

what in the first stage of digestion in the mouth

Answer 25

chewing food combines with the saliva. Which turns food into a moist lump called the bolus. Enzymes present in the saliva break down any starch

Question 26

what happens in the digestive system once food travels to the esophagus.

Answer 26

your food then travels from the mouth to the into the esophagus. There are nerves in the surrounding esophageal tissue sense the bolus's presence and trigger peristalsis. Which is a series of defined muscular contractions. That propels the food to the stomach.

Question 27

what happens to food once in the stomach. the first part of digestion in the stomach.

Answer 27

Once in the stomach it is left at the mercy of the muscular stomach walls, which bound the bolus, breaking it into chunks. Hormones, secreted by cells in the lining, trigger the release of acids and enzyme rich juices from the stomach wall that start to dissolve the food and break down its proteins. These hormones also alert the pancreas, liver and gallbladder to produce digestive juices and transfer bile in preparation

Question 28

what is the second part of digestion in the stomach.

Answer 28

after three hours inside the stomach the once shapely bolus in now a frothy liquid called chyme and then it move to the small intestine.

Question 29

what happens in the digestive system once food in travels to the small intestines.

Answer 29

the liver sends bile to the gallbladder which secretes it into the first portion of the small intestine called the duodenum. The duodenum dissolves the fats floating in the slurry of chyme, so they can be easily digested by the pancreatic and intestinal juices that have leached into the scene. These enzyme rich juices break the fat molecules down into fatty acids and glycerol for easier absorption into the body. the enzymes also carry out the final deconstruction of proteins into amino acids and carbohydrates into glucose. This happens in the small intestines lower regions the jejunum and ileum.

Question 30

what is bile

Answer 30

A yellowish-green liquid that digest fat,
