,stenosis - correct ans:turbulent flow can be caused by blood flowing rapidly in the usual direction
through an abnormally narrowed valve.
insufficiency - correct ans:blood flowing backward through a damaged, leaky valve.
MAP - correct ans:Mean arterial pressure - average pressure during the cycle (MAP = DP + 1/3 (SP-DP)
SP - systolic pressure - correct ans:maximum arterial pressure reached during peak ventricular ejection
DP - diastolic pressure - correct ans:the minimal arterial pressure occurs just before ventricular ejection
begins
Pulse Pressure - correct ans:the difference between systolic and diastolic pressures.
The most important factors determining the magnitude of the pulse pressure. - correct ans:1) stroke
volume
2) speed of ejection of stroke volume
3) arterial compliance
capillaries - correct ans:permeate every tissue of body (except cornea). major sites of nutrient,
metabolic end product, and fluid exchange between blood and tissues.
hemoglobin - correct ans:erythrocytes contain large amounts of this protein with which O2 and CO2
reversibly combine. Oxygen binds to iron atoms Fe2+ in the hemoglobin molecules.
iron - correct ans:gets stored mainly in liver, bound up in a protein called ferritin
, ventilation - correct ans:exchange of air between atmosphere and alveoli by Bulk Flow
exchange of O2 and CO2 - correct ans:between alveolar air and blood in lung capillaries by Diffusion
transport of O2 and CO2 - correct ans:through pulmonary and systemic circulation by Bulk Flow
Exchange of O2 and CO2 between blood and tissue capillaries - correct ans:by Diffusion
cellular utilization - correct ans:of O2 and production of CO2
Hypoventilation - correct ans:defect anywhere along the respiratory control pathway from the medulla
through the respiratory muscles
hypoventilation may be caused by: - correct ans:severe thoracic cage abnormalities
hypoventilation may be caused by: - correct ans:major obstruction of the upper airway.
Increased arterial PCO2 - correct ans:the hypoxemia of hypoventilation is always accompanied by a ?
diffusion impairment - correct ans:results from thickening of the alveolar membranes or a decrease in
their surface area. it causes blood PO2 and alveolar PO2 to fail to equilibrate.
shunt - correct ans:an antomical abnormality of the cardio system that causes mixed venous blood to
bypass ventilated alveoli in passing from the right side of the heart to the left side of the heart.
shunt - correct ans:an intrapulmonary defect in which mixed venous blood perfuses unventilated alveoli.
Arterial PCO2 generally does not increase because the effect of a shunt on arterial PCO2 is counter
balanced by the increased ventilation reflexively stimulated by the hypoemia.
ventilation perfusion inequality - correct ans:is by far the most common cause of hypoxemia. It occurs in
congestive obstructive lung diseases and many other lung diseases.
