What 2 ways can blood enter the heart?
Ans- →Superior vena cava
→Inferior vena cava
Blood enters the heart via SVC and IVC but there is another exception. What is
it?
Ans- Azygous veins
The Azygous vein drains where?
Ans- SVC
,What part of the heart is this?
→ P-wave starts at sinoatrial node in crista terminalis
→ impulse travels to AV node
Ans- Right Atrium
What happens when there is a SA node impulse to AV node and delayed (P-R)
interval?
Ans- AV Nodal Delay
What part of the heart is this?
→end of diastole 120ml
→tricuspid valve closes S-1
→heart sound: isovolumetric contraction
Ans- Right ventricle
,Name this EKG:
→ QRS complex (ventricular contract)
Ans- Ventricular depolarization
What part of the heart is this?
→ mid-systole (halfway through)= enough pressure to blow open pulmonic
semilunar valves
Ans- pulmonary artery
What part of the heart is this?
→ blood exits via 2 pulmonary arteries to lungs
Ans- pulmonary artery
What carries DE-O2 blood?
Ans- pulmonary artery
What carries DE-O2 blood?
, Ans- umbilical artery
Ventricular filling is % passive and % active
Ans- 80% passive
20% active from atrial contraction
SA node impulse to AV node is shown as what on an ECG?
