The cardiac cycle, heart sounds and Blood pressure

A network of specialized muscle cells is found in the heart's walls
Cardiac Conduction System
Respiratory System
Cardiovascular System
Heart Sound
There are three phases in the cardiac cylce: they are "the diastole of the chambler of the heart", "the systole of the atria" and "the systole of the ventricles"
True
False
During this phase, all chambers are relaxed.
Diastole Phase of the Chamber of the Heart
Systole Phase of the Atria
Systole Phase of the Ventricle
The atria contact briefly for only about 0.1 second. This brief concentration completely fills the ventricle with blood
Diastole phase of the Chamber of the Heart
Systole Phase of the Atria
Systole Phase of the Ventricle
At this point, the "Atrioventricular valves" opens while the "Semilunar valves" are closed
Diastole Phase of the Chamber of the Heart
Systole Phase of the Atria
Systole Phase of the Ventricle
During this systole phase of the ventricle, the "Atrioventricular valves" closes and the "Semilunar valves" opens
Diastole Phase of the Chamber of the Heart
Systole Phase of the Atria
Systole Phase of the Ventricle
Tool to detect the heart sound
Stethoscope
Sphygmomanometer
As the chambers of the heart alternately contract and relax, distinctive heart sounds produced
Heart Sound
Blood Pressure
Pulsse
Is the force exerted by the circulating blood upon the walls of the blood vessels
Heart Sounds
Blood Pressure
Pulse
Blood pressure is obtained using instrument called ________
Stethoscope
Sphygmomanometer
An impulse can be felt over "artery" -> from "alternate" expansion -> beating of the "heart" -> heart pushes "blood" into the "aorta" -> elastic walls creates a "pressure wave" -> This impact is the "pulse"
Pulse
Heart Sound
Blood Pressure
What is the normal pulse rate?
60 to 100
10 to 50
110 to 50
160 to 200
