great video, thank you!

as oer heart rate if someone in supine has 66-70 heart rate im sitting 72-78 and in standing 85-90 is consider normal?i mean supine to standing 15-20 heart beat difference are normal?Also if we stand for 1 hour heart rate will up more or will go down?

Interesting

wth

What condition (ie combo of carbs/fats) causes large amounts of superoxides and especially hydroxyls to be generated in people with Metabolic Syndrome?

You can be the best if improve to explain what is going on in your mind best of luck

Dear Mr. Daniel. In the most of modern textbooks dedicated to cardiovascular physiology one can find that Frank-Starling relationship is defined as a stroke volume (SV) plotted against preload, so that SV is monotonic and increasing function of preload; is also stated that preload can be presented as left ventricular end-diastolic volume or pressure (!) implying that reader can use them interchangebly. The latter seems quite strange, because first of all we talk about volumes in Frank-Starling relationship only, aren't we? And for the second, such interchangeability (i.e. LVEDP and LVEDV) neglects the concept of compliance. Compliance represensts the first derivative dLVP/dLVV (left ventricular pressure and volume respectively) and is not constant for full possible range of left ventricular pressure values, suggesting that is also the function of pressure. For example in article of Noble (doi.org/10.1042/cs0540001), the idea of SV as function of LVEDV is criticised, because: "... stroke volume/end-diastolic volume curve describes a different property of the heart (i.e. the constancy of end-systolic volume for a given end ejection pressure) from the length-tension curve of the muscle". The same author concludes "... the relationship between stroke volume and end-diastolic volume gives no information about the pressure-volume or length-tension curves" . So my question is which variable should we use, when describing the preload? Thank you!

When you are explaining what would happen in pipes, shouldn’t the pressure in the arteries that is in level with the heart (like a. Brachialis) change when lying down vs standing. Because when you lie down you’re heart will loose the 0.5 meters to the head (roughly 40 mmHg). I agree with you that this is not the case in humans because the baroreceptor reflex will kick in (and the receptors are very close to the heart and have the same height)

Thank you. I have a very bad professor for a grad course, and I could NOT understand how to do systems of ODEs with multiple variables. I was missing just one piece of such simple information. If my own professor had just done a tutorial like this for us, I would be enjoying this course so much more. THANK YOU for saving me in my class!!!

Thank you for this video but I have a question: what is the value of pression in the right atrium and in the left atrium?

thank you, but what is k1,k2 and Km, please

Very nice and interesting video ! Thank you !

great work. we enjoyed....

I’ve been struggling for 5 months,and you made it simple in 15 minutes god bless you

Tech itch - feel the pressure drop, feel the pressure drop ..

So increasing gravity kill more people than nuclear bomb no wonder north Korea move people into underground or mountain and increase gravity

Interesting

I will verify the potency of the , Notovα Shocking Plan (look it up on Go ogle) that works with blood pressure level. Several other products I`ve tried only reduced the blood pressure for the moment. There is no other treatment on the market that accomplish what it reveals. After a couple of weeks, my blood pressure level has kept the 145/90 line. With Perfect Pressure its now working at 120/70.

Some resources on quantitative analysis of oxidative phosphorylation can be found here: beards-lab.github.io/QAMAS_book/Abstract.html

super helpful, very informative!

A close friend closed to me have used also this , Notovα Shocking Plan blood pressure level alternative I uncovered on Go ogle. His hypertension was stroke level 158/120. A result of this method is so visible instantly specially if you eat the ideal foodstuff. It has gradually dropped and Fourteen days later with healthier eating his blood pressure is 128/84..

Thank you so much! I have mock exams tomorrow for my second year medical course, and I am definitely weakest in physiology. Not sure watching this today will save my grade tomorrow, but I'm going to come back and study it in more detail after the mock because it was really helpful :)

I have experienced high blood pressure & consuming prescriptions from the time that I was 26 years old. Right here is the very first high blood pressure solution that has ever really worked to reduce my pressure the natural way. The medicinal drugs prescribed to me to take weren`t of used anymore after having a four week period of making use of this guideline. I researched about this tip by Google. This guide is Jason Cυnobroke With thanks

Nice video, Dan!

Several times in the text I mistakenly refer to "Sarnoff and Braunwald", where the correct reference should have been to "Sarnoff and Berglund", as referenced in the slides.

Why when we wound in our foot we feel heavy in wounds like presure on wound area, but when we make horizontal position like rest in bed, the presure on wound like disappear

Sir, How to compute the k values if the concentration time curve is given.

Could u explain the effects of twice the amount of Earths gravity on larger planets on the muscles, skeleton, skin and organs?

Winner of a video, I been tryin to find out about "how to get high blood pressure back to normal" for a while now, and I think this has helped. Ever heard of - Tenaniel Wonderful Eventuality - (do a search on google ) ? Ive heard some pretty good things about it and my neighbour got great success with it.

and for a headstand www.ncbi.nlm.nih.gov/pubmed/31219304?fbclid=IwAR0-vCJ_1HcIVb_kB0zQIykP2aNb1oyNy61Q-9ZNY5ZQSE_sWKK6HAvcg00

There is a much faster way to do all this in Simulink, I personally suggest you can explore that.

Helpful!

thank you so much for this valuable tutorial...

Thanks for the video. I come back to this every time I have to do kinetic modeling.

Thank you for you explanations, it made more clear view of what steps I should take to build a biological model.

Hello, What about inhibitor kinetics? I + HMGR (E) ----> K2 K-2 ---> EI

Hi Daniel. It is a great video clip. Thank you. But, could you please explain a little bit about the PLUS and MINUS signs in the differential equations? I'm not 100% sure the signs. Gabriel, if you can help, it is appreciated too. Thanks.

Very helpful!

Awesome video!

Awesome video! Super informative.

Hii.. today's is my exam and i really wanted to know as soon as possible the initial values for n, m, h ??? and also, the V(m) value that is membrane potential value ? will it be -70mV or will it change for three of n, m , h? please answer..

Really thanks you

What is the unit of Y axis and why we have to put initial conditions as 1? thank you

Thank you a lot for help in understanding this material.

Hi, We have a big problem in simulation for the kinetic reaction. The problem is in the ode function with the comment : undifinded function with double and arguments. Can you help us please ! Best of regards.

thanks alot sit 😃

This is a rat model you've used, do I understand correctly? So there's probably no provision in it for gravitational hydrostatic column delta P, is there?

Thank you, very helpful videos that made the concept easier for me!
