Digestive System

Question 1

What path does food take when you eat?

Answer 1

Mouth, Esophagus, Stomach, Small Intestine, Large Intestine, Rectum

Question 1

Ingestion

Answer 1

eating and drinking, location: mouth

Question 2

digestion

Answer 2

chemical or mechanical breaking down of food, mouth, small intestine, large intestine, stomach

Question 3

Absorption

Answer 3

The transport of water and digested food into the bloodstream and tissues, small intestine, large intestine, stomach

Question 4

Elimination

Answer 4

Removing wastes or unusable materials from the body, rectum

Question 5

enzymes

Answer 5

functional proteins that break down food (digestive enzymes)

Question 6

saliva

Answer 6

contains enzymes that begin chemical digestion in mouth

Question 7

liver

Answer 7

digestive and excretory organ that produces bile, secrete enzymes into the small intestine to aid with the breakdown of fats and any remaining proteins and carbohydrates.

Question 8

gallbladder

Answer 8

digestive organ that stores bile

Question 9

pancreas

Answer 9

gland that produces digestive enzymes and insulin, secrete enzymes into the small intestine to aid with the breakdown of fats and any remaining proteins and carbohydrates.

Question 10

water absorption

Answer 10

occurs in the large intestine

Question 11

bile

Answer 11

enzyme that breaks down fat into small fat droplets in the small intestine, allows fat to be produced by liver,

Question 12

esophagus

Answer 12

A muscular tube that connects the mouth to the stomach.

Question 13

peristalsis

Answer 13

involuntary wavelike, muscular movements that move food through the digestive system, Waves of smooth muscle contractions that move food through the esophagus toward the stomach are called peristalsis.

Question 14

stomach

Answer 14

chemical digestion by acid, leads to small intestine

Question 15

small intestine

Answer 15

enzymes digest foods, major absorption location, most chemical digestion takes place here, Other organs, including the liver and pancreas secrete enzymes into the small intestine to aid with the breakdown of fats and any remaining proteins and carbohydrates.

Question 16

large intestine

Answer 16

final section of digestive system, bacterial digestion, water absorption, last stage of digestion occurs in the large intestine, ctually shorter than the small intestine—1.5 m versus 6–8 m. water from food is reabsorbed and waste products are compacted and prepared for elimination from the body, many bacteria are involved here, not dangerous

The last section of the large intestine is called the rectum. This is where waste collects until it is time for elimination. The solid waste products leave the body through an opening called the anus.

Question 17

4 tasks of digestive system

Answer 17

ingestion, digestion, absorption, elimination

Question 18

organs that create enzymes for digestion

Answer 18

salivary gland, liver, pancreas, stomach

Question 19

Why does the gallbladder need to be close to the liver?

Answer 19

Liver makes the bile, and gallbladder holds it, so they need to be close

Question 20

Why can you live without a gallbladder?

Answer 20

The bile is just passed further down into your digestive system instead of being collected in the gallbladder.

Question 21

carbohydrate

Answer 21

An energy-rich organic compound, such as sugar or a starch, that is made of the elements carbon, hydrogen, and oxygen (Simple carbohydrates, such as the ones shown in Figure 2, are smaller molecules and taste sweet. Complex carbohydrates, such as fiber, are larger molecules. )

Question 22

Proteins

Answer 22

body needs protein for growth and body repair, made of smaller components called amino acids

Question 23

Fats

Answer 23

provide a concentrated energy source and the body also uses fats for long-term energy storage, Saturated fats usually come from animal products, such as lard. They are solid at room temperature. Unsaturated fats usually come from plant products and are oils, such as olive oil. They are liquid at room temperature.

Question 24

Vitamins

Answer 24

nutrients that help your body with chemical reactions. They do not provide any energy or building materials, but without them, you would not be able to function, ( Fat-soluble vitamins, such as A and K, are stored in the fatty tissues of the body and released when needed. Water-soluble vitamins, such as vitamin C, dissolve in water and are not stored in large amounts by the body. Citrus fruits, such as oranges, are high in vitamin C.)

Question 25

Mineral

Answer 25

nutrients that are not made by the body, but are needed to carry out chemical processes, (Calcium for bones and iron for blood are two examples of minerals that are taken in through the diet.)

Question 26

Water

Answer 26

most important nutrient for survival

Question 27

Mechanical Digestion

Answer 27

The mouth and stomach are the main places, movement of the food through the esophagus and the intestines is also part of, Waves of smooth muscle contractions that move food through the esophagus toward the stomach are called peristalsis.

Question 28

Chemical Digestion

Answer 28

starts in the mouth, which is shown in Figure 3, with an enzyme found in saliva. acts specifically on the carbohydrate starch. Saliva also moistens the food, continues in the stomach, where other enzymes and hydrochloric acid further break down food, The partially-digested material then passes into the small intestine, where most chemical digestion takes place.
