Atrio-ventricular Valves 6 of 40 What does SAN stand for? Sino Atrial Node 7 of 40 Which side of the heart recieves deoxygenated blood? Right 8 of 40 Why is there lower pressure in the right side of the heart? Because the blood has less distance to travel 9 of 40 Where does the Aorta take the blood? Away from the heart and around the body 10 of 40 What does ECG stand for? Electrocardiogram 11 of 40 What does an ECG monitor do? It monitors the heart, to observe how the heart is functioning 12 of 40 What does the Purkyne tissue do? Carries a wave down the septum 13 of 40 Where is the apex situated? At the bottom tip of the heart 14 of 40 What is stroke volume? The amount of blood pumped out of the left ventricle in one cardiac cycle 15 of 40 What is cardiac output? The amount of blood pumped out of the left ventricle in one minute 16 of 40 What is the formula for cardiac output? Cardiac output = stroke volume x heart rate 17 of 40 What is tachycardia? A fast irregular heart rate 18 of 40 What is bradycardia? A slow irregular heart rate 19 of 40 Why is the heart myogenic? The heart can make itself contract and does not need any stimulation from a nerve 20 of 40 What is the name for the valve that allows blood to pass through to the pulmonary artery? Pulmonary Valve 21 of 40 What is myocardial infarction? Heart Attack 22 of 40 Where does an impulse in the heart first start? Atrio-centricular Node (AVN) 23 of 40 After the AVN where is the impulse sent? The Sino Atrial Node (SAN) 24 of 40 What is the Ventricular Spetum? The muscle between the left and right ventricles 25 of 40 Which vein brings deoxygenated blood into the heart? The Vena Cava 26 of 40 What is the plural form for Vena Cava? Vena Cavae 27 of 40 What are the two parts of the Vena Cava called? Inferior and Superior 28 of 40 Roughly how many times will the cardiac cycle repeat itself every minute? 75 29 of 40 What phase would the atria be in, if the ventricles were in systole? Diastole 30 of 40 What phase would the ventricles be in, if the atria were in Diastole? Systole 31 of 40 How can heart rate be measured? By counting how many pulses are felt in an artery per minute 32 of 40 What part of the body can a pulse be measured? Anywhere, where there is an artery next to a bone 33 of 40 Why should you not use your thumb to measure your pulse? It has its own pulse 34 of 40 Which artery is the pulse usually measured when using the fingers? The Radial Artery 35 of 40 What is the measurement of heart rate? Beats per minute 36 of 40 What other instruments can be used to measure the heart rate? Blood Pressure Monitor or Stethoscope 37 of 40 Whre can pulse also be measured? The carotid arterty (neck) or the brachial artery (upper arm) 38 of 40 What are the units of measurement for stroke volume? Cm3 39 of 40 What are the units of measurement for cardiac output? dm3 min-1 40 of 40
