Front 1

List some metabolic factors that enhance cerebral blood flow?

Back 1

CO2/hydrogen ion(decreased pH) and adenosine.

Front 2

What causes the typical cardiac sounds?

Back 2

First- Closing of the A-V valves.
Second- closing of the pulmonary and aortic valves.
Third- associated with inrushing of blood into the ventricles during early diastole.
Fourth-inrushing of blood in the ventricles caused by atrial contraction.

Front 3

Stenosis in one kidney results in what?

Back 3

The release of renin and the formation of angio. 11 from the affected kidney. Angio. 11 stimulates aldosterone production and increases total peripheral resistance by constricting the majority of blood vessels.

Front 4

What is the significance of blowing murmers?

Back 4

These murmers of high pitch are usually associated with valvular insufficiency. For diagnosis, systolic and diastolic pressures should be identified.

Front 5

What would be the result of infusing histamine into the brachial artery?

Back 5

H. is a vasodilator that is released by mast cells and basophils. In this case, it would decrease arterial resistance and increase blood flow. this would also result in an increase in capillary hydrostatic pressure and the capillary filtration rate.
