2/3 ap poll: The predominant driving force that moves blood back to the heart in the veins is skeletal muscle or ventricular contractions?
It's like you are writing these polls with my anatomy curriculum. We just finished the heart.
This is like the third time this has happened too
I'll try to keep it up.
You better ;-) . We're moving on the immune system
I have a 30 year old very healthy patient who got a blood clot after surgery. Good reason to move.
Skeletal muscle. This is one of the reasons people who have sedentary jobs NEED to get up and move around. The blood flow back to the heart from the legs is primarily dependent on muscle contractions in your calves and thighs. Fluid displacement and
and venous valve failure are likely conditions for those who sit for extended periods on a regular basis.
Oooohhhh, tricky! 😜
I'm up, I'm UP!!!
Sedentary "Я" Us! I'm mostly confined to a medical lift chair, getting up every few hours to walk about fifteen steps (with a walker) to the bathroom. I try to move my legs more frequently while in the chair to pump blood and lymph.
Tough stuff, Tom. I appreciate how hard you work despite your issues.
Thanks. And great poll series!
