1. In the aortic arch, there are special cells called baroreceptors. These connect to a nerve which sends up signals to the medulla oblongata- what is the name of this exact nerve for the aortic arch? 2. What in the heart allows for coordinated contraction of the anterior papillary muscle? 3. Fibrin is well known for reinforcing platelet clots. But which clotting factor forms the cross links of the fibrin, reinforcing that as well? 4. What is the name of the hypotenuse of the Triangle of Koch, and where is this located? 5. A man has the blood type of iBiB, and is homozygous for the rH factor. He has a child with a woman with the blood type of iAiB, who is also homozygous for the rH factor. What is the percent chance that their child will be AB+? 6. What is the most common cofactor needed for the next clotting factor activation? 7. What are the two main cardiovascular centers? 8. Define the RAAS and how it regulates blood pressure.1. Vagus nerve?? 2. Chordae tendineae 3. Factor XIII (fibrin stabilizing factor) 4. No clue 5. 50% 6. Thrombin? 7. In the medulla are the accelerator and inhibitor centers 8. The renin-angiotensin-aldosterone system in the kidneys regulates blood pressure because Angiotensin II causes vasoconstriction that leads to an increased blood pressure.
1. Yes
2. No, it's moderator bands. Chordae tendineae help to stabilize valves while these have branches that cause for more synchronized conduction.
3. Yes
4. It's a triangular structure in the right atrium, with it's boundaries being the coronary sinus orifice, tendon of Todaro, and septal leaflet of the right atrioventricular valve. The longest side is the Tendon of Todaro.
5. Yes
6. Close, that's actually just the last factor before fibrinogen is activated to fibrin. The correct answer is Factor IV, calcium ions
7. I guess that could be counted right, but in actuality the cardioacelerator and cardiodecelerator/inhibitor make up the cardiovascular center, the other one is the vasomotor center.
8. Yes
Go ahead, your turn!
