lab exam 2 Flashcards
what is the size of a lymph node
1 cm in diameter or smaller
list the 4 parts of a lymph node
lymphatic nodule
germinal center
capsule
trabecula
what is the function of lymph nodes
primary function is to filter lymph
how does lymph fluid gain entry into the lymph node
afferent lymphatic vessels
what cells are multiplying in the germinal centers
B-cells
why are these cells important in Acquired adaptive immunity
plasma cells produce antibodies
what is another name for a lymphatic follicle
lymphatic nodules
active natural immunity
the ANTIGEN is transferred
the individuals immune system is responsible for immunity
ex. exposure to polio virus
active artificial immunity
the ANTIGEN is transferred
the individuals immune system is responsible for immunity
ex. DPT + MMR injections
passive natural immunity
the ANTIBODY is transferred
the individuals immune system is NOT responsible for immunity
ex. mothers milk pased through the placenta
passive artificial immunity
the ANTIBODY is transferred
the individuals immune system is NOT responsible for immunity
ex. anti-snake venom bodies
lab 5 KNOW THE MODELS
midsagittal head
human torso
larynx
lung
how many ways can air travel through the respiratory tract on the way to the lungs
2 - mouth and nose
is the trachea anterior or posterior to the esophagus
anterior
where are the cilia located
trachea
is the trachea anterior or posterior to the esophagus
anterior
mucus is produced specifically by what glands
submucosal glands
which way does CO2 travel between the capillaries and alveoli
CO2 moves out of the capillaries and into the alveoli
the ___________is loacted between the parietal and visceral membrane
pleural space
be able to identify the parts of the trachea/esophagus
cartilage
pseudostratified ciliated columnar epithelium
seromucous glands in submucosa
be able to identify the parts of the lung
capillary
alveolar sac
alveoli
why are pseudostratified ciliated columnar epithelium and the seromucous glands important for healthy lung function
they trap and sweep dust particles
what function does the cartilage in the trachea serve
it provides structural support and prevents collapse of the trachea (keeps airway open)
what crosses the alveolar capillary wall (respiratory membrane)
O2 + CO2
why is smooth muscle important around bronchioles
they control the diameter of the brochiole thus regulating airflow to lungs
