The respiratory mucosa is

Pseudostratified cilated columnar epithelium

The upper respiratory system consists of all the following except

larynx

Functions of the nose are all of the following except

none of the above

(functions include: warms the air, humidfies the air, filters the air)

Bronchial tree consists of

-primary bronchi

-secondary bronchi

-bronchioles

The bronchioles

control of airflow resistance and or distribution in the lungs.

Boyle's law

for a gas in a closed container and at a constant temperature, pressure is inversely proportional to volume

Cellular respiration

is the intracellular reaction of O2 with organic molecules to produce CO2, water, and ATP

External respiration is subdivided into the following integrated processes except:

Exchange of gases between blood and the lungs

Dalton's Law

each of the gases contributes to the total pressure in proportion to its relative abundance

Gas exchange at the respiratory membrane is efficient for the following reasons except

the total surface area is small

Local vasodilators accelerate blood flow in response to

decreased temperature

Kinins

cause contraction of visceral smooth muscle, but they relax vascular smooth muscle via NO, lowering blood pressure

Inhibits platelet aggregation and promotes vasodilation

prostacyclin

The chordae tendonae and papillary muscles play important roles in the normal function of the AV valves.

true

The factors that affect tissue perfusion are all the following expcept

autoregulation

monitor the degree of stretch in the walls of carotid and aortic sinuses

baroreceptors

Theories of autoregulation are the following except

temperature theory

The P wave

accompanies the depolarization of the atria

Phases of the cardiac cycle

-atrial systole

-atrial diastole

-ventricular systole

-ventricular diastole

The atrioventricular (AV) valves prevent backflow of the blood from the ventricles to the atria when the ventricles are contracting.

true

Cardiac output is the amount of blood pumped by the left ventricle in one second

false

Isovolumetric contraction period

lasts approximately 270 msec

Ventricular conducting cells consist of the AV bundle, bundle branches, and

Purkinje fibers.

Connective tissue fibers of the heart function to do the following except

stabilizes the heart valves

There are two atrioventricular valves

bicuspid (mitral), tricuspid

End diastolic volume is

130

S2 is caused by the

closing of the semilunar valves
