Thank u sir ....bahut achcha video bnaya ....samjh nhi aa rha tha cardiovascular response ......mera master in physiotherapy me kal exercise physiology ka exam hai
It is today I found your channel.. you are doing a great work.. I have been confused about these things so far.. Now only I can understand the theory.. Thank you..🙏
mercy thomas The two types of blood pressure are systolic and diastolic. When heart goes in systole, LV creates a certain force/pressure and pumps the blood into the arterial system. The arterial systolic pressure would thus be proportional to that force generated by the LV. However, when heart goes in diastole, now LV isn’t creating any force. Blood is already there in the arterial system; it will already have some pressure that will exerted on the vessel wall. This then (diastolic BP) will depend on what? It will depend on the state of the vessel (for e.g., constricted or dilated). If the vessel is constricted, then as a result of an equal and opposite force, the pressure (diastolic) in blood will also be correspondingly higher. A constricted vessel or a narrowed lumen, on the other hand is the contributor of the peripheral resistance. Hence, by correlation, diastolic BP becomes the indicator of peripheral resistance.
I really love your videos and I always find new ideas even when I watch something I already know about! You explain from a broad view and connect everything amazingly and smoothly! and I LOVE IT! However, you rarely show up in my searches on TH-cam!! and I search a LOT about the same subject over and over. Yet, It is only two times that your video has shown up in my search, today and a year ago! I believe it's the way you write your titles. TH-cam advice to make titles as straightforward as possible and short with extra care of the initial words. I took a quick look at your titles and they're really long and filled with unrelated words "like the first sentence in this video for example". Think like a student. The only thing we will type on the search engine is the concept we're studying or a specific problem in a short sentence. Any extra details/hashtags can be added in the description box or maybe not. Start with this adjustment and learn more about it, it's really a game-changer! Wish you the best
Hi. First of all, Thanks. For the kind words of appreciation. I see myself as a humble servant of the subject (physiology) and want to give best to the students of medicine. Yes, TH-cam has its own algorithm. I am slowly coming to terms with it. So, in coming days, content put out by me will be easily gettable. I am thankful to you for all these suggestions. Regards,
Ver well explained, Sir. May I ask if these physiological changes constantly occurring every time one exercise or they can be differ in long term exercising/ athletics? 2nd question, in isotonic exercises, there is decrease in peripheral vascular resistance, decrease in diastole and decrease in afterload. Each of these three indicating the same. Right?
1. The changes explained here are mostly applicable to short term, or let's say, one episode of exercise. It does not take into account the compensatory changes that may occur (over a period of time) with regular exercise. 2. In isotonic exercise, basically there is a decrease in peripheral resistance. And yes, the other effects are colinear with this decrease in peripheral resistance.
Sir , as of now ( in 1st year ) we know that resistance vessels are capillaries , so will the muscle contraction have effect on those arterioles ? If on the arteries as well than we know that blood is an incompressible liquid , so the blood has to go somewhere , where it will go in case arteries are constricted?
In the first sentence , you mentioned capillaries and in the second, you have said arterioles. Arterioles are the resistance vessels, not the capillaries. If the muscle goes into a sustained state of contraction, then the vessels inside the muscle will be compressed so that, some of the blood may be pushed forward, but after that the fresh blood may not be able to enter the muscle. You might have read that the running, jogging are called AEROBICS; why? Aren’t all exercises aerobic? Answer is no. The isometric sustained tension development will compress the vessel, hinder the blood entering the muscle . The muscle will metabolize anerobically. So, some of the blood which was already there, will be pushed forward, in the form of venous return, and new blood will not be able to enter.
@@VivekSirsPhysiology sry sir , that was a typo .I meant arterioles .So inside muscle arteriole is what gets compressed right ? Ok, I got the aerobics part
@@P25125 Not only the arterioles; all vessels tend to get compressed within a contracting muscle. Especially if it’s a sustained contraction. So, two different things may be sorted out - Arterioles are the resistance vessels as they offer greatest resistance to blood flow. That’s one thing. Second, various vascular beds (in various organs and tissues) offer resistance to blood flow. The total peripheral resistance is the sum of these resistances in various organs/tissues. Over here, skeletal muscle vascular bed contributes maximum peripheral resistance due to its contractile property. (And, it’s not ONLY the arterioles within a skeletal muscle; all the vessels within the muscle will be compressed during contraction, thereby contributing to peripheral resistance).
Sir i didnt understand why in isotonic contraction peripheral resistance decreases, cs as u said when muscle contracts the vessel there experiences more resistance
In isotonic type exercises, there are alternate rhythmic contractions and RELAXATIONS of the muscle groups. (Compare this with isometric exercises with sustained type of contractions.) Consider any aerobic (isotonic) type of exercise. There are rhythmic contractions and relaxations in agonist & antagonist muscle groups. Since muscles are allowed to relax intermittently, it will allow the opening up of the blood vessels within those muscles. The metabolites released by the muscle will cause those vessels to dilate, resulting in a decrease in peripheral resistance.

I have never seen a teacher that explained this way...
Really appreciate
Thanks ! Thanks for the comment. Regards.
Totally!!
The way you are teaching is awesome.. I got each and every point you taught..
Thank you again..👍👍
Thank u sir ....bahut achcha video bnaya ....samjh nhi aa rha tha cardiovascular response ......mera master in physiotherapy me kal exercise physiology ka exam hai
Excellent sir
In viva,they had asked me this ,thankusomuch sir😊
Good to know that it was of help. Regards,
Wow nice sir ye video u tube PR khi nhi mili thank you sir ye convey clear krne k liye 😊
Superb!! U make hard topics so easy👏👏
Nice👍
Usefull 🙂
What a beautiful explanation sir, maza aa gya ❤
@@kartik6805 Really? Thanks….!
Thanks for all the efforts for us 🙏😊u made the topic crystal clear
Best explanation
I got the concept crystal clear
@@art_junction9386 Thanks..!
Crystal clear concept. Thank you Sir
Best teacher .. thanks alot for wonderful lectures
Thank.you.so.much.for.your.informative.lectures.
thank you vivek sir !!!
Thanks sir 😃
Nice explanation sir 🎉❤❤❤
Very well explained sir..to the basics.. tq 🙏
Thank You Sir❤️.
thanks so much. This lecture is very hopeful with me
It is today I found your channel.. you are doing a great work.. I have been confused about these things so far.. Now only I can understand the theory..
Thank you..🙏
Helpfull🙌🏻🙌🏻
Nice work sir👏👏,
Sir is there any relation prooving that peripheral resistance directly proportional to diastolic bp...

👍👍👍👍
Thnk u sir
Is their any difference between 2 question,, cardiovascular change during exercise or Effect of exercise on cardiovascular system?
No difference. It's the same.
@@VivekSirsPhysiology Thanks a lot sir , you clear my doubt.

He makes easy topics difficult 😖🥴🥵😵
Which part? I mean, which part or topic was easy and was made difficult?
Most of the videos.. I get more confused after watching the videos
Ok. I take the point; the teaching style should change or improve. I’ll try.
Regards,
Not at all sir! You make the topics a lot easy and logical imo @@VivekSirsPhysiology
Thank you so much
