Gastrointestinal System Flashcards
(88 cards)
1
Q
What is the main role of the digestive system?
A
It regulates the energy breakdown for the cells of the body
2
Q
What is the definition of digestion?
A
The process in which substances are changed into forms that can be absorbed through the cell membranes
3
Q
Where does the process of digestion begin, and how?
A
In the mouth. The teeth macerate the food and saliva binds it
4
Q
What are the pharynx and the esophagus?
A
The pharynx (in which are included the nasopharynx, ornpharynx, laryngopharynx) and esophagus combined makeup the passageway to the stomach. No digestive process happens here.
5
Q
What are the four parts of which the stomach is composed?
A
The cardiac, the fundus, the body, and the pyloric regions
6
Q
What are the functions of the stomach?
A
To receive food via the esophagus, mix it with gastric juices, initiate digestion of proteins, carry on a small amount of absorption, move food into small intestine
7
Q
What are the ten main organs that makeup the digestive system?
A
Mouth Pharynx Esophagus Stomach Small intestine Large intestine Liver Gallbladder Pancreas
8
Q
What are the four types of gastric juices secreted in the stomach and where are they secreted from?
A
Chief cells secrete digestive enzymes
parietal cell secrete hydrochloric acid
Mucous cell secrete mucous to protect walls against pepsin
Chief cells secrete pepsin in form of pepsinogen. Pepsin is a protein splitting enzyme and most efficient in acidic environments.
9
Q
What is the mixture of gastric juices and food called?
A
Chyme
10
Q
What are the main functions of the small intestine?
A
Receives secretions from liver and pancreas, finalizes digestion of nutrients from chyme, absorbs different products of digestion, moves remaining residues to large intestine
11
Q
What are the three pieces of the small intestine called?
A
The duodenum
The ileum
The jejunum
12
Q
What are the finger like projections in the small intestines called and what do they do?
A
Villi, they increase the surface area of the intestinal lining while glands release a watery fluid that keeps the chyme moving. The increased surface area maximizes absorption of nutrients.
13
Q
How long does it take for food to pass through the small intestine?
A
3-10 hours
14
Q
What are the five main parts of the large intestine called?
A
cecum colon Ascending colon Transverse colon Descending colon Sigmoid colon, rectum and anal canal
15
Q

16
Q
What’s the only organ that will regenerate itself if part of it is damaged?
A
The liver, up to 25 percent can be removed
17
Q
What are some of the functions of the liver?
A
Conversion of glucose to glycogen
Conversion of non-carbohydrates to glucose
Oxidation of fatty acids
Synthesis of lipoproteins phospholipids and cholesterol
Conversion of carbs and proteins into fats
Conversion of hormones like insulin thyroxin adrenaline estrogen, etc
Dissemination of amino acids
Synthesis of urea
Sunthesis of blood proteins
Interconversion of amino acids
Stores glycogen vitamins a, d, b13 and iron
Remove damaged blood cells and foreign substances by phagocytosis
Alters chemical composition of toxins to try to expel them from body
Secretes bile which is necessary for digestion of fats, absorption of fat soluble vitamins (a d e f and k) and helps to assimilate calcium
18
Q
What does the gall bladder excrete?
A
Bile and bile salts which enhance absorption of fatty acids and some fat soluble vitamins. It breaks down the fat globs that they form when they clump together which are hard to digest. This is called emulsification
19
Q
What does the pancreas excrete and what do they do?
