    for me, it's equally important to have someone with a clear speaking voice explaining each lecture. Dr. John Campbell has a great voice for this. Coupled with his knowledge, I am learning better here then in class... ;)

    1. All veins have one way valves which prevent back flow
    2. Two systems of veins (superficial and deep) Deep veins are inside muscle so when muscle contract high pressure is imposed on the deep vein which propels them back to the RA. Superficial veins usually feed into deep veins. Lack of muscle contraction could cause DVT (Stasis of blood leads to thrombus which travels in to RA then into lungs where it leads to a pulmonary embolism)
    3. Varicose veins: when valves fail blood regurgitates from deep back into superficial and keeps back flowing as more valves fail. Keep muscle active, but some component is genetic

    thank you so much for this information. please continue with the information as i am now seeing varicose veins that are moon shape in my thighs. i conveyed this to my regular doctor and she said i should see a vascular doctor. not enough information is given about this topic. i see many females particularly that have problems with veins and valves.

    Did you mention SUCTION? Yep. Newly discovered relatively, or newly recognized, there is an actual UPDRAFT in the secondary cycle. The blood is not left with zero pressure from above, but with negative pressure, assisting or assisted from positive pressure by musculature of the calf and thigh - but it really a good question, isn't it. And it raises additional questions about venous disease progression, which cascades suddenly from simple edema and lack of reversal treatment - which by its nature must be a home medicine. And many other factors of blood, muscle, posture, and medicinals in therapy.

    Venous return. Can an injury flare up and accompanying inflammation cause this?
    If so, could this set off a veritable flood of sweating and a tingling, fizzing sensation?

  • @awesome4life633
    @awesome4life633 6 лет назад

    One thing I don’t get- how is venous return equal to cardiac output with so much lower pressures? Also, if muscles are not contracting, does cardiac output have to decrease since venous would decrease?

  • @psalmsraj188
    @psalmsraj188 4 года назад

    but sir, while walking the muscles are contracted and relaxed causing veins to draw blood towards Inferior vena cava.
    but while sleeping there is no muscle activity in out muscles and what causes the blood to go forward towards heart.

      I wish there was something simple I could tell you SRP, but what you have told me are just descriptions, so there is nothing I can specifically say. The most important thing is to see a local specialist doctor who will be able to assess you on n individual basis. Have you done this? I wish you well.
