Answer 9

larynx

Question 10

podocyte cells are part of what?

Answer 10

GLOMERLUS CAPILARIES. cover the exterior surface of the glomerular capillaries and contribute to the glomerular filtration membrane

Question 11

which of the following blood vessels is directly associated with the nephron

Answer 11

corticil radiate vein

Question 12

The function of the respiratory system is to bring oxygen to the blood and to remove the carbon dioxide. The respiratory system is composed of two parts:

Answer 12

Conducting Portion

Respiratory Portion

Question 13

conducting Consists of a series of cavities and tubes conducting air to the lungs.

Answer 13

Nose 
Nasopharynx 
Larynx 
Trachea 
Bronchi 
Bronchioles (terminal; transition between the conducting and respiratory portions).

Question 14

Areas of respiratory gas exchange consisting of :

Answer 14

Alveolar ducts
Alveolar sacs
Alveoli

Question 15

Conducting parts provide a passageway air to reach the lungs and also for conditioning the air to make it suitable for the body by:

Answer 15

filtration (by hairs)
cleansing (by mucus and ciliary action)
moistening (by mucus)
warming or cooling (by heat exchange via blood vessels)

Question 16

cells that line most of the conducting regions.

Answer 16

respiratory epithelium

Question 17

Pharynx divided in 3 parts:

Answer 17

Nasopharynx
Oropharynx
Larngopharynx

Question 18

The nasopharynx

Answer 18

serves as only an air passageway, and contains the pharyngeal tonsil, which traps and destroys airborne pathogens.

Question 19

The oropharynx

Answer 19

is an air and food passageway that extends inferiorly from the level of the soft palate to the epiglottis.

Question 20

The laryngopharynx

Answer 20

is an air and food passageway that lies directly posterior to the epiglottis, extends to the larynx, and is continuous inferiorly with the esophagus

Question 21

The larynx has two functions:

Answer 21

1- phonation
(creation of sounds for speech)
2- control of the air pathway

Question 22

hyperventilation

Answer 22

increase in rate and depth of breathing that exceed the body’s need to remove CO2

Question 23

low CO2 levels in the blood

Answer 23

(hypocapnia)cerebral blood vessel constriction, brain perfusion reduction and cerebral ischemia results
low bp/hypoventilation

Question 24

low PCO2

Answer 24

inhibits respiration, makes it slow and shallow

raises bp/hyperventilation
