What are two events occurring in the body that aids in venous return?
Skeletal muscle contractions which pulls the blood back and valves which close after blood has passed through it.
What is venous thrombosis prevention?
Venous thrombosis prevention is a means to prevent blood clots from forming in veins within the body.
What exchanges blood between the arterial and venous systems?
The arterial and venous systems are connected in the body tissues by capillaries, and also in the heart.
What is a plasmapheresis process?
Two venous lines are used. This method requires slightly less blood volume to be out of the body at any one time.
How does elevation of the damaged ankle decrease inflammation?
Elevation of any edematous (swollen) body part, especially an appendage, decreases inflammation by using gravity to aid venous return of blood back to the heart. In damaged tissue, blood will flow to the area for healing. When the damaged part is elevated, it promotes venous return. For elevation as a purpose of edema reduction to be truly effective, the elevated body part must be higher than the heart. In other words, if you are sitting on a couch with your ankle on a coffee table, that is not true elevation.

What two things aide venous return within the body?
wht?
What is the medical term meaning abnormal circulatory condition characterized by decreased return of venous blood from the legs to the trunk of the body?
venous insufficiency
Name two events occuring within the body that aid in venous return?
1. Respiratory "Pump". Pressure changes that occur in the thorax during breathing. 2. Muscular "Pump". Contraction and Relaxation of skeletal muscles surrounding the veins.
What two events aid in venous return?
Venous blood does not have the relative advantage of high pressure that arteries have. Therefore, veins utilize two mechanisms to return the blood to the heart. First, veins have valves in them to keep the flow in one direction. This important especially when blood in the lower body must move upwards against gravity. Second, veins bone muscle contractions assist in pressuring the veins to move the blood along.
How does the pressure in the astronaut's suit help the body work?
The pressure in an astronaut's suit helps venous return; in other words, it helps blood get from body tissues back to the heart.
How does venous return impact the quality of performance?
venous return is the blood returning to the heart. Which means that the more blood is pumped out, the more returns. Starling's Law states that stroke volume is dependent upon venous return, therefore, if VR increases, SV increases, or, if VR decreases, SV decreases as well. So, the healthier the heart is, it pumps more blood providing the oxygen needed in the body for muscles to work. The faster the blood provides the oxygen, your body would have more oxgyen, this means that there would be less oxygen debt at the end of the event or game.
Explain why venous return uses the superficial veins in the skin as the return route when an individual is exercising.?
By using superficial veins more heat is able to be radiated from the body, this helps maintain a lower core temperature.
What is central venous pressure in medical terms?
The central venous pressure or right atrial pressure is the pressure of the blood in the thoracic vena cava near the right atrium. The pressure reflects the amount of blood that return to the heart and can be pumped back through the body.
Explain why arterial blood flow is pulsatile and venous flow is not?
Venuous is return blood to the heart. The passage through the body has slowed down and evened out the blood pressure.
What is venous varicoses?
A varicose vein is an enlarged, twisted superficial vein. They can occur pretty much anywhere on the body, but mostly on the back of the lower legs.
What is venous thrombosis prevention?
Venous thrombosis prevention is a means to prevent blood clots from forming in veins within the body.
