PE - venouse return

HideShow resource information
what is venouse return
it is the amount of blood entering the heart
1 of 7
what are the 4 venouse return mechanisms
skeletal pump -- pocket valves -- inspiration (breathing mechanism) -- suction pump of the heart
2 of 7
what is the skeletal pump
muscle contractions compress veins = blood is pushed up towards the heart
3 of 7
in relation to the skeletal pump, why is it important to do a cooldown
active coolddown after exercise mans that blood is still getting to the worked muscles
4 of 7
what are pocket valves and where are they located -- whay are they important
one - way valves -- lie inside the veins -- assist the direction of blood flow and prevent backflow
5 of 7
what is the respiratory pump / breathing mechanism / inspiration
greater breathing movments alter the pressure in the thorax , compressing the veins which assist the flow of blood.
6 of 7
what is the suction pump
pumping action of the heart causes blood to flowinto replace the blood pumped out = suction action in veins close to the heart
