What is afterload? Correct Answer-The pressure or resistance against which the ventricles must pump to eject blood What is preload (end-diastolic volume)? Correct Answer-Force exerted by the blood on the walls of the ventricles at the end of diastole What is a contraction? Correct Answer-Ability of cardiac cells to shorten, causing cardiac muscle contraction in response to an electrical stimulus What is venous return? Correct Answer-The amount of blood flowing into the right atrium each...

Normal Central Venous Pressure (CVP) range 2-8 mmHg Normal Pulmonary Artery Occlusion Pressure (PAOP) range 6-12 mmHg Normal Pulmonary Artery Systolic (PAS) range 20-30 mmHg Normal Pulmonary Artery Diastolic (PAD) range 5-15 mmHg Normal Pulmonary Artery Mean (PAM) 11-20 mmHg Normal Systemic Vascular Resistance (SVR) range 800-1200 mmHg Preload volume left in the left ventricle at the end of diastole What is preload affected by? venous retu...

minimum urine output for adult 0.5mL/kg/hr ADH (antidiuretic hormone) - water retainer - vasoconstrictor (also called Vasopressin) - produced by hypothalamus - store and released from posterior pituitary ADH pathway - hypothalamus senses low blood volumed and increased serum osmolality - signal pituitary to release ADH - ADH causes kidney to retain water - water retention increases blood volume and decreases serum osmolality ANP (atrial natriuretic peptide) -...

How does chronic aortic stenosis lead to left ventricular hypertrophy? Chronic aortic stenosis leads to left ventricular hypertrophy bc of increased workload of pumping blood through a narrow opening. The left atrium can also enlarge but mainly causes left ventricular hypertrophy. The right ventricle will remain normal for a period of time. That's why LHF happens first then leads to RHF. Chronic mitral stenosis will cause enlargement in which area? Left atria hypertrophy. In pt with Mitral v...
