A comprehensive set of questions and answers covering key concepts related to the cardiovascular system, particularly focusing on conditions like aortic aneurysms, aortic dissection, venous disorders, hypertension, and heart function. It includes explanations of various cardiovascular terms, mechanisms, and clinical manifestations, making it a valuable resource for students studying cardiovascular physiology and pathology.

Don't miss anything!
Aortic aneurysms - ANS ✓-weakness in the wall of the aorta that makes it susceptible to rupture
predisposition to varicose veins
Ejection fraction - ANS ✓-measurement of the volume percentage of left ventricular contents ejected with each contraction
Pre load vs after load vs inotropy - ANS ✓-pre-load: ventricular filling/end- diastolic pressure; volume of blood prior to systole, largely determined by venous return to heart
L atrium: receives oxygenated blood from lungs Fibrous skeleton of the heart - ANS ✓-4 interconnecting valve rings
Stable vs unstable plaque - ANS ✓Unstable plaque - white/grey, platelet rich; large lipid core with a thin fibrous cap made of smooth muslce -- can easily rupture Stable plaque - red; small lipid core with a thick fibrous cap made of smooth muscle -- doesn't easily rupture Pericarditis - ANS ✓-inflammation of the sac surrounding the heart; associated w/ increased capillary permeability
ST-segment elevation MI: s/s + tx - ANS ✓-ischemic death of myocardial tissues; usually abrupt, or chronic is progressed from unstable angina/NSTEMI
R side; prolongs closure of pulmonary valve and produces separation of aortic + pulmonary components
Extends from the terminal portion of phase 3 until the beginning of phase 4 Cardiac arrhythmias develop EKG: what each segment represents - ANS ✓P: SA node P-Q: delay in AV node tranmission QRS: ventricular contraction/purkinje S-T: repolarization of ventricles
normal sinus rhythm, origin=SA node can be d/t fever, blood loss, anxiety, exercise, SNS stimulation, loss of vagal tone Supraventricular vs ventricular arrythmias - ANS ✓-supraventricular=dx of atrial rhythm or conduction above the ventricles (ex: afib, a flutter, PAC)
Third degree AV block - ANS ✓-atria and ventricles function independently
Larynx - ANS ✓voice box; passageway for air moving from pharynx to trachea; contains vocal cords Tracheobronchial tree - ANS ✓branching structures of the respiratory system that resemble an upside-down tree trunk and its branches; includes trachea, bronchi, and bronchioles. Function of lungs vs lobules vs alveoli - ANS ✓-lungs: gas exchange, inactive vasoactive substances (bradykinin), convert angiotensin I to II. reservoir for blood storage.
