Gross Respitory Organs/ Histology Of Restitory Organs/anatomy And Physiology Of Digestive Organs

Front 1

nassal cavity function

Back 1

to warm, moisturize, and filter air entering the body before it reaches the lungs.

Front 2

paranasal sinuses function

Back 2

Decreasing the relative weight of the front of the skull, and especially the bones of the face. Increasing resonance of the voice. Providing a buffer against facial trauma.

Front 3

pharynx function

Back 3

in the process of swallowing and it serves as a pathway for the movement of food from the mouth to the esophagus.

Front 4

hyoid bone function

Back 4

is to serve as an anchoring structure for the tongue.

Front 5

larynx function

Back 5

houses the vocal folds (vocal cords), which are essential for phonation. The vocal folds are situated just below where the tract of the pharynx splits into the trachea and the esophagus.

Front 6

epiglottis function

Back 6

It is normally pointed upward during breathing with its underside functioning as part of the pharynx, but during swallowing, elevation of the hyoid bone draws the larynx upward; as a result, the epiglottis folds down to a more horizontal position, with its superior side functioning as part of the pharynx.

Front 7

vocal folds function

Back 7

They are structures which open for breathing, come together during swallowing, and vibrate as air passes between them during speaking or singing.

Front 8

trenchea function

Back 8

is essentially an air-conducting tube (commonly known as your windpipe) that connects your larynx to the rest of your respiratory system. Though the cylindrical tube is only about three-quarters of an inch in diameter and 4 to 5 inches long, you wouldn't be able to survive without it.

Front 9

diaphragm function

Back 9

The muscle that separates the chest (thoracic) cavity from the abdomen. The diaphragm is the main muscle of respiration. Contraction of the diaphragm muscle expands the lungs during inspiration when one is breathing air in.

Front 10

bronchus function

Back 10

are extensions of the windpipe that shuttle air to and from the lungs. Think of them as highways for gas exchange, with oxygen going to the lungs and carbon dioxide leaving the lungs through them

Front 11

bronchiole function

Back 11

passageways by which air passes through the nose or mouth to the alveoli (air sacs) of the lungs, in which branches no longer contain cartilage or glands in their submucosa. They are branches of the bronchi, and are part of the conducting zone of the respiratory syst

Front 12

alveolus function

Back 12

Gas exchange of oxygen and carbon dioxide takes place in the alveoli. Oxygen from the inhaled air diffuses through the walls of the alveoli and adjacent capillaries into the red blood cells. The oxygen is then carried by the blood to the body tissues

Front 13

what tissue are found in the nasal cavity

Back 13

is lined with ciliated pseudostratified columnarepithelium (also called respiratory epithelium).

Front 14

what tissue is found in the Tanchea

Back 14

epithelium

Front 15

what tissue is found in the Bronchus

Back 15

epithelium

Front 16

what tissue is found in the Bronchiole

Back 16

They are lined with respiratory epithelium, which is classified as ciliated pseudostratified columnar epithelium

Front 17

what tissue is found in the Alveolus

Back 17

epithelial

Front 18

oral cavity function

Back 18

is to begin the process of digestion.

Front 19

pharynx function

Back 19

For the digestive system, its muscular walls function in the process of swallowing and it serves as a pathway for the movement of food from the mouth to the esophagus.

Front 20

esophagus function

Back 20

to carry food, liquids, and saliva from the mouth to the stomach

Front 21

esophageal sphincter function

Back 21

is a bundle of muscles at the top of the esophagus. The muscles of the UES are under conscious control, used when breathing, eating, belching, and vomiting. They keep food and secretions from going down the windpipe.

Front 22

stomach function

Back 22

Partial digestion of the food takes place here. The churning action of thestomach muscles physically breaks down the food. The stomachreleases acids and enzymes for the chemical breakdown of food. The enzyme pepsin is responsible for protein breakdown.

Front 23

rugae function

Back 23

is to allow the stomach and other tissue to expand as needed to assist in the digestion of food.

Front 24

pyloric sphincter

Back 24

it plays an important role in digestion, where it acts as a valve to controls the flow of partially digested food from the stomach to the small intestine.

Front 25

small intestines

Back 25

absorption of nutrients and minerals from foo

Front 26

villi function

Back 26

are specialised for absorption in the small intestine as they have a thin wall, about one cell thick, which enables a shorter diffusion path. They have a large surface area so there will be more efficient absorption of fatty acids and glycerol into the blood stream.

Front 27

ileocecal valve function

Back 27

to limit the reflux of colonic contents into the ileum.

Front 28

large intestine function

Back 28

is to absorb water from the remaining indigestible food matter and transmit the useless waste material from the body.

Front 29

salivary glands function

Back 29

produce saliva, which keeps the mouth and other parts of the digestive system moist. It also helps break down carbohydrates (with salivary amylase, formerly known as ptyalin) and lubricates the passage of food down from the oro-pharynx to the esophagus to the stomach.

Front 30

pancreas function

Back 30

t is part of the digestive system and produces important enzymes and hormones that help break down foods. The pancreas has an endocrine function because it releases juices directly into the bloodstream, and it has an exocrine function because it releases juices into ducts.

Front 31

liver function

Back 31

filters and processes blood as it circulates through the body. It metabolizes nutrients, detoxifies harmful substances, makes blood clotting proteins, and performs many other vital functions.

Front 32

gall bladder function

Back 32

is to store and concentrate bile, a yellow-brown digestive enzyme produced by the liver
