🗑
|
||||
| Trace the cell of a single RBC as it goes through the heart: | Superior vena cava -> right atrium -> right ventricle -> left atrium -> left ventricle -> aorta
🗑
|
||||
| Mitral (bicuspid) valve separates: | left atrium and left ventricle
🗑
|
||||
| Aortic Valve separates | left ventricle and aorta
🗑
|
||||
| Tricuspid valve separates | right atrium and right ventricle
🗑
|
||||
| Pulmonary valve separates | right ventricle and pulmonary trunk
🗑
|
||||
| Layers of the heart from most superficial to deep are: | Pericardium - myocardium - endocardium
🗑
|
||||
| Each atria has an ear-like (flap-like) conical muscular pouch that arises from it, which is visible when looking at the surface of the heart. Referred to as: | auricles
🗑
|
||||
| What is the first branch of the aorta as blood leave the heart? | Brachiocephalic artery
🗑
|
||||
| What muscle lines the inner surface of the atria, giving their walls a comb-like appearance? | Pectinate muscle
🗑
|
||||
| The tricuspid valve has [#] flaps while the mitral valve has [#] flaps. | 3 and 2
🗑
|
||||
| While the inner atria walls are lined by [blank], the inner ventricle walls are lined with [blank]. | pectinate muscle and trabeculae carneae
🗑
|
||||
| What two structures function together to help prevent backflow through the tricuspid and mitral valves? | Papillary muscles and chordae tendineae
🗑
|
||||
| The aortic and pulmonary valves are (AV or semilunar) valves, while the tricuspid and mitral valves are (AV or semilunar) valves. | semilunar and AV
🗑
|
||||
| What causes CAD? | a partial blockage of a coronary vessel, which can be caused by either a plaque buildup or a thrombus (blood clot) in the vessel
🗑
|
||||
| What causes an MI versus CAD? | MIs are caused by the complete blockage of a coronary vessel, while CAD is only a partial blockage
🗑

| Someone who has chest pain with exertion, and not at rest, is likely having an MI rather than CAD. True or False? | False, MI pain continues at rest
🗑
|
||||
| What is the purpose of ductus arteriosus in fetal blood circulation? | Allows blood to bypass the pulmonary circuit and go straight from the pulmonary artery to the aorta
🗑
|
||||
| What is the corresponding structure of ductus arteriosus in adults? | grows into ligamentum arteriosum, connective tissue string
🗑
|
||||
| While listening to your partner's apical and then radial pulse, you notice a large pulse deficit. What might this indicate? | cardiac impairment/ a weak heart that is unable to efficiently pump blood
🗑

🗑
|
||||
| How to calculate pulse pressure: | difference between systolic and diastolic pressures
🗑
