Dalton’s Law which describes the contribute of individual gases in a mixture to the total gas pressure is helpful in explaining:

oxygen diffusion into blood

this is a diagram of the Hemoglobin Saturation curve: What condition would cause the curve to “Shift” as it shown here (arrows show direction of shift):

low pH or high PC02

Normal arterial blood pH is:

7.35-7.45

According to the process of ventilation-perfusion coupling, when there is obstructed ventilation in a portion of the lung, what will occur as a response to that:

decreased perfusion in that portion

Standard atmospheric air pressure at sea level is:

760 mm Hg

Boyle’s law which relates volume and pressure of a gas is helpful in explaining:

ventilation

Each lung contains about 150 million tiny sacs that provide the surface area for gas exchange. These tiny sacs are termed:

alveoli

The upper and lower respiratory tracts are separated at this structure:

larynx

This “flap” covers the opening into the larynx during swallowing food or fluids:

epiglottis

The structural separation of the primary bronchi at the distal portion of. The trachea is lined with any nerve endings that trigger spasmodic coughing. this structure is termed the:

carina

The majority of cells in the alveoli are:

macrophages

Typically, when the diaphragm contracts, when occurs in the lungs:

air enters the lungs

Air entering the intrapleural cavity causes:

pneumothorax

Slow, shallow or obstructed breathing is termed:

hypoventilation

At increaseing elevation, which of the following would NOT be decreasing:

actual % of 02 in air

what percentage of air is composed of oxygen

21%

What condition must be maintained to allow for typically expansion of the lungs and prevent pneumothorax:

intrapleural pressure must be lower than intrapulmonary pressure

hypercapnia results from:

high blood PC02

which of the following will NOT decrease oxygen diffusion into blood at the respiratory membrane:

thinning of the respiratory membrane

which of the following typically has highest P02:

blood in pulmonary veins

according to the mechanism of ventilation-perfusion coupling, if P02 of alveolar air is low, what compensatory response will be triggered by this mechanism:

pulmonary vest constriction

typically, where in the body is PC02 the highest:

at the systemic tissue

According to the mechanism of ventilation-perfusion coupling, if pulmonary blood flow is high, what compensatory response will be triggered by this mechanism:

bronchodilation

In the process of ventilation-perfusion coupling, what are the two factors that are being “coupled”? (More than one answer, check all that apply)

alveolar air flow, pulmonary blood flow

Typically, high blood pH causes____Hb 02 binding:

greater

Typically, decreased Hb-02 binding at the alveoli leads to:

decreased oxygen delivery to tissues

Typically, low arterial blood PC02 causes___Hb-02 binding:

stronger

Respiratory acidosis can be compensated by:

increased bicarbonate retention by kidneys

Typically, high arterial blood PC02 causes what change in blood pH:

low pH

Typically, a high level of HC03 in blood causes____alkalosis:

metabolic

Metabolic alkalosis can be compensated by:

hypeventilation

Typically, having a low blood pH will cause what change in breathing:

hyperventilation

Hypoventilation causes what change in arterial blood PC02?

increase

hyperventilation causes what change in arterial blood PC02?

decrease

low arterial blood PC02 causes what change in blood?

alkalosis

respiratory alkalosis can be compensated by:

increased bicarbonate excretion into urine by kidneys

Typically, high arterial blood PC02 causes____:

respiratory acidosis
