|---|---|---|---|---|---|
| which valve is aslo called tricuspid valve, opening ifrom right atrium to right ventricle has 3 cusps, prevents backflow | right atrioventricular (AV) valve
🗑
|
||||
| a 2 cusp bicurspid valve or mitral valve that when open allows blood to flow from left atrium to left ventricle | left atrioventricular valve
🗑
|
||||
| have 3 cusps support like tripid, no muscular support, prevent back flow into ventricles from aorta or pulmonary trunk | semilunar valves AKA pumonary adn aortic tricuspid valves
🗑
|
||||
| which coronary artery supplies blood to right atrium, portions of both ventricles, cells of SA and AV node, marginal arteries at surface of right ventricles adn posterior interventricular artery | right coronary artery
🗑
|
||||
| which coronary artery supplies blood to left ventricle, left atrium and interventricular septum/ has two main branches consisting of cirumflex artery and anterior interventricular artery | left coronary artery
🗑
|
||||
| atria depolarization corresponds to what wave | P wave
🗑
|
||||
| Ventricular depolarization correspond to what wave of the ECG | QRS complex
🗑
|
||||
| ventricular repolarization conrresponds to what wave on teh ECG | T wave
🗑
|
||||
| AV nodal DELAY /which time interval is from atrial depolarization (contraction) to the QRS complex (time it takes the for the depolarization to reach the AV node) | P-R interval
🗑
|
||||
| time from end of ventricular depolarization to the beginning of ventricular repolarization | ST segment
🗑
|
||||
| time from ventricular depolarization to repolarization | QT interval
🗑
|
||||
| time during which ventricles are relaxing and filling | TP interval

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
