How many beats does the heart avg.? mL?

75 beats per minute; 70-80 mL per beat!

2

Right atrium has? receives? which valve?

right auricle (little ear)
pectinate muscles
crista terminalis
- recieves deoxygenated blood from IVC
- tricuspid valve going from RA to RV

3

Right ventricle has?

is most of anterior surface
has trabeculae carnae
-receives from RA
-blood goes through semilunar valve to pulmonary arteries (deoxy. blood) to the lungs

4

Left atrium receives? valve?

has oxygen rich blood from lungs via 4 pulmonary veins
most of posterior surface of heart
bicuspid valve to LV (mitral valve)- chorda tendinea, Papillary muscles

5

Left ventricle has? pumps to?

Apex of heart
Inferior surface of heart
trabeculae carnae
pumps to Aorta- therefore rest of body
