25
Pepsin
enzyme that breaks down proteins into smaller peptides, it is produces in the stomach and is one of the main digestive enzymes
26
chief cells
cell in the stomach that releases pepsinogen and chymosin
27
parietal cells
secrete hydrochloric acid and intrinsic factor
28
gastric pit
indentations in the stomach which denote entrances to the tubular shaped gastric glands
29
Greater Omentum
large apron like fold of visceral peritoneum that hangs down from stomach, extends from the greater curvature of stomach
30
Lesser Omentum
double layer of peritoneum that extend from the liver to the lesser curvature of the stomach
31
Function of large intestine
absorb water from the remaining indigestible food matter and transmit the useless waste material from the body
32
Acinar cells
produce digestive enzymes
33
Hepatocytes
tissue of liver, involved in protein synthesis
34
Kupffer cells
specialized macrophages located in liver
35
Trachea
provides air flow to and from the lungs
36
Terminal bronchioles
air passes through the nose of mouth to the alveoli (air sacs) of lung
37
Respiratory bronchioles
to ensure that incoming air is supplied to each alveolus
38
Alveoli
gas exchange of oxygen and carbon dioxide
39
Macrophages
its job it to locate microscopic foreign bodies and eat them
40
Clara cells (club cells)
are dome-shaped cells with short microvilli, found in the small airways (bronchioles) of the lungs
41
Surfactant
lower the surface tension at the air/liquid interface within the alveoli of the lung
42
Herring-breuer reflex
reflex triggered to prevent over inflation of the lung
43
Respiratory control centers
located in the medulla and pons, they receive controlling signals of neural, chemical and hormonal nature and control the rate and depth of respiratory movements of the diaphragm
44
Carotid body
responds to stimulus and triggers action potential through afferent fibers of the glossopharyngeal nerve
45
Larynx
allows air to be directed into the respiratory organs for gas exchange and also is responsible for producing vocal sounds
46
Cricoid cartilage
provides attachments for the posterior & lateral cricothyroid muscle, ligaments, muscles, and cartilages
47
Arytenoid cartilage
allow vocal folds to be tensed, relaxed, or approximated
48
Glottis
several voicing sounds between vocal folds when they vibrate
49
Epiglottis
seals off the wind pipe during eating
50
Thyroid cartilage
forms the Adams apple, largest and uppermost of 9 cartilages within the larynx
51
Diaphragm
separates the thoracic cavity from abdominal cavity and as the diaphragm contracts, the volume of the thoracic cavity increases and air is drawn into the lungs
52
Partial pressure
rate of diffusion is determined by partial pressure
53
Carbonic anhydrase
aids in the conversion of carbon dioxide to carbonic acid & bicarbonate ions
54
Chloride shift
occurs in the cardiovascular system and refers to the exchange of bicarbonate and chloride across the membrane of red blood cells
55
Hemoglobin
transports oxygen from the lungs to the body’s tissues, then transports carbon dioxide out of the tissue back to the lungs
56
Pleura
two membranes that cover the lungs and line the chest cavity, purpose is to cushion the lungs during respiration
57
Cardiac notch:
lateral deflection of the anterior border of the left lung, accommodates the space taken up by the heart
58
Ciliated columnar
moves mucus and other substances via cilia and is found in the upper respiratory tract, the Fallopian tubes, the uterus, and central part of the spinal cord
59
Squamous cells:
in mouth, lips, and cervix,
60
black lung disease
long term exposure to coal dust
61
brown lung disease
caused by exposure to cotton dust
62
phrenic nerve
originates in neck and passes down between lung and heart to reach diaphragm. Important for breathing, passes motor information to diaphragm and receives sensory info from it
