LOW blood pressure needs to be recognized as the devastator it is. More accurately, low blood VOLUME. When blood flow to tissues is reduced, so is supply of oxygen and nutrients, and removal of wastes That means every single tissue and organ is underserved, and collapse is inevitable. Low muscle tone results in inability to stand on feet for any length of time, as well as POTS upon standing up from sitting or reclining, and general weakness, lassitude and incoherence at other times. as the brain suffers from the deficit as well. Inadequate O2 supply to tissues results in chronic anxiety and insomnia, as all is not really well in this domain, and hypervigilance is necessitated. Since kidneys cannot process nitrogenous wastes quickly enough, bladder instability results and high-protein foods are poorly tolerated. Since there is not enough water in the system, constipation results. Heat is poorly tolerated because blood vessels dilate and lower blood volume further. Cold is poorly tolerated because blood in conserved for internal organs, leaving subject's muscles more dysfunctional than the norm. And then there is the social isolation of never having quite the capacity of others around you, yet not being helpless enough in any given category to qualify for accommodation. A public education campaign is called for.

So the episode that is about the greatest problem in American healthcare (cardiovascular disease due to high blood pressure) is also one of the least watched of the series. So spread this out! People really need to stop eating so much.

So question: If having a strong heart can be dangerous in that a stronger heart requires more oxygen it doesn't get, does that mean the stronger hearts of endurance athletes is ultimately a dangerous thing?

I butter my bacon. I even butter my coffee. I liked learning about the flow, steps and processes. The visuals were very helpful but I don't agree on the information about sodium and butter.

Intelligent but lacks teaching and communication skills, your teaching could also raise students blood pressure trying to pick all the contents of your teaching. Take it slow doc

Why hasn't anybody commented on 2: 15 -Or had any other hands on experience with fluids. then flow can change depending on a number of factors- Hank, you nasty xD

When you rearranged the blood flow equation to basically be the MAP=CO x TPR my brain had a eureka moment and was very happy. Thank you Hank from 4 years ago.

So how do energy drinks and excess caffeine affect these things? Messing with the hormones that make the heart work harder repeatedly?
