Cardiovascualr Power Point - Exam 2

Question 1

____ is the period of ventricular contraction

Answer 1

systole

Question 2

_____ is the period of ventricular relaxation

Answer 2

diastole

Question 3

During _____ the pressure in the left atrium slightly exceeds pressure in the L ventricle, so blood flows from the L atrium to L ventricle through the open mitral valve.

Answer 3

diastole

Question 4

As systole begins, the L ventricle contracts causing ventricular pressure to exceed L atrial pressure closing the mitral valve (produces ______). L ventricular pressure continues to increase causing blood to flow through the open aortic valve.

Answer 4

heart sound 1, S1

Question 5

During _____ the pressure in the left atrium slightly exceeds pressure in the L ventricle, so blood flows from the L atrium to L ventricle through the open mitral valve.

Answer 5

diastole

Question 6

As systole begins, the L ventricle contracts causing ventricular pressure to exceed L atrial pressure closing the mitral valve (produces ______). L ventricular pressure continues to increase causing blood to flow through the open aortic valve.

Answer 6

heart sound 1, S1

Question 7

The left ventricle ejects most of its blood, L ventricle pressure begins to fall, and the aortic valve closes (produces _________).

Answer 7

heart sound 2, S2

Question 8

Similar events with regard to valve closure are simultaneously occurring on the R side of the heart. Right sided heart pressures are much _______ than left side however, and right sided events occur slightly _____.

Answer 8

lower

later

Question 9

Additionally, R heart filling time is increased during ______ increasing R ventricular stroke volume and duration of R ventricular ejection. All of this contributes to slightly ______ closure of the of the pulmonic valve during inspiration, creating what is called a physiologic split of the s2 heart sound: instead of one smooth sound audible, there are two audible sounds A2 and P2. During expiration, just the smooth singular s2 is audible.

Answer 9

inspiration

delayed

Question 10

You may also hear extra heart sounds in certain conditions (s3, s4 referred to as gallops): S3, kentucky, which comes directly after S2 and can be present as a pathologic condition in older adults due to changes in ______ (volume overload, decreased L ventricular compliance).

Answer 10

ventricular compliance

Question 11

Heart Murmurs

Answer 11

Review

Question 12

Right internal jugular vein connects with the right subclavian vein to then form into the ______ which leads directly into the R atrium.

Answer 12

superior vena cava
