Cardiovascular System 5

Question 1

– Is a reoccurring sequence of mechanical electrical events during a single heartbeat

Answer 1

The cardiac cycle

Question 2

— Is the relaxation of the heart chamber While — is the contraction of the heart chamber?

Answer 2

-Diastolic
- Systole

Question 3

A graphic record of heart activity measured via electrode placed on the skin

Answer 3

ElectroCardiogram

Question 4

The atrial will be repolarizing when the ventricles are contracting, true or false?

Answer 4

True

Question 5

— measures the sound produced by the heart or valves

Answer 5

Phonocardiogram

Question 6

Phases of the cardiac cycle

Answer 6

• Ventricular filling
• Atrial systole
• Isovolumetric contraction
• Ventricular ejection
• Isovolumetric relaxation

Question 7

The lub sound occurs in the — phase while the dub sound occurs in the — phase

Answer 7

• Isovolumetric contraction
• Isovolumetric relaxation

Question 8

How to measure a cardiac output

Answer 8

Stroke volume x heart rate

Question 9

How to measure a stroke volume

Answer 9

End diastolic volume - end systolic volume

Question 10

— is the measure of the amount of blood pumped by the heart every minute while — is the amount of blood ejected from the heart in the single contraction?

Answer 10

• cardiac output (The average cardiac output is 5 L of blood pumped by the heart per minute)
• stroke volume (roughly on an average of 70 mL)

Question 11

The process in which the autonomic nervous system affect the timing of the heart rate is known as the?

Answer 11

Chronotropic effects

Question 12

The sympathetic nervous system increases the heart rate, while the parasympathetic nervous system decreases the heart rate

Answer 12

True
