ACIDS, BASES AND BUFFERS
An acid is defined as a substance that releases protons or hydrogen ions (H+), e.g. hydrochloric acid (HCI), carbonic acid (H2CO3).
base is a substance that accepts protons or hydrogen ions, e.g. bicarbonate ion (HCO3-), and HPO4- -
Buffer is a solution of weak acid and its corresponding salt which resists a change in pH when a small amount of acid or base is added to it.
By buffering mechanism a strong acid (or base) is replaced by a weaker one.
Normal pH Of The Body Fluids
The normal pH of arterial blood is 7.4
pH of venous blood and interstitial fluids is about 7.35
The pH of blood is maintained within a remarkable constant level of 7.35 to 7.45.
Regulatory Mechanisms to maintain normal Blood pH
Buffer mechanism: First line of defense
The respiratory mechanism: Second line of defense
Renal mechanism: Third line of defense.

Short, crisp and on to the point. Just what I was looking for.
Thank you for simplifying the topic sir.
Glad to hear that ☺️
This was so helpful for me!!!!!!! Thank you so much may allah bless you ❤️💕💕💕💕💕💕💕💕💕💕💘💘💘💘💘💕💕💕💕💕💘💘💕💘💕💘💕💘💕💕💕💕💘❤️❤️❤️❤️💕❤️💕❤️💕❤️💕❤️💕❤️💕❤️

**02.26 wrong explanation**
Increasing Of PH is “Acidosis” Decreasing of PH is “Alkalosis”
No, increase in pH is alkalosis and decrease in pH is acidosis
I’m so confused! I thought 💭 Acidosis is a condition in which there is too much acid in the body fluids. It is the opposite of alkalosis (a condition in which there is too much base in the body fluids). Am i right? Or wrong ? Let me know about this?
@@arungaliyt9186 You are absolutely correct. Normal physiological pH of blood is 7.35-7.45. If pH is less than 7.35 dn it's acidosis and if it is greater than 7.45 dn it is Alkalosis
Oh sry! I’m about to tell that increasing on H+ ions in blood plasma is Acidosis and it indicates decreased PH and decreasing of H+ ions is Alkalosis and it indicates increased PH. (Thanks for your response 🙏👍🏻👍🏻🤝🤝)
@@arungaliyt9186 Yes dear. My pleasure
Buffer is a solution..... Not a substance
NYC presentation and clearly explained
☺️🙏
Thank you ...
I have a question
Does phosporic acid act as a buffer ?
Inorganic Phosphates act as a buffers
Ok thanks
Phosphate is the major Intracellular buffer and Bicarbonate is the major extracellular buffer
Sir pdf format ah send panringala please🙏🏻
07:29 blood buffers starts
please what is relationship between HP and potassium K ??
Sir can you please share the ppt?
It's there on the website
Thank you sir ❤️😌
Sir, please provide notes of all lecture video on the website 🙏🙏🙏🙏🙏🙏🙏 please sir
Yes half of them are already uploaded. Remaining one I will update in the few days.
@@Biochemistrybasics THANK YOU so much sir🙏🙏, i request to you provide notes as soon as possible, because my 1st year exam hold on January
@@prashantgupta9777 no issues
So so much thank you sir.
Was looking for this since the begining and finally understood the concept. ☺
Most welcome dear
So helpful thank you sir .
In bicarbonate buffer system can we use weak acid as carbonic acid and strong base salt as sodium bicarbonate??
Thank you sir... it's really helpful 👍
You are welcome 😊. Keep loving biochemistry and do spread the word about the channel 😊
So easily explained .Must watch
Thanks Evelyn. ✌️🙏
Thank you sir
You are welcome tushar. Please spread the word. Tk cr 😇
thank you very much it is the most detailed video which I encountred
Glad to hear that
Thank 🙏 u soo much sir
Sir is there notes for ur lectures
Dts on the website
thank you so much for making the things very easy.
Glad you liked it. Keep loving biochemistry
Thank u sir
🙏😇
👍🏻 Great sir
Short and easy
Thanks dear
thanks
✌️😊
Thanks
🙏😀
Sir ppt bhetel k
🙏🙏🙏🙏🙏👏👏👏👏👏😍😍
Thank you
Thanks sir...l will follow the other videos for you to get more and more informations...thank you again
You are most welcome dear. Keep loving biochemistry
Thanks sir i understood the topic thoroughly
🙏😇
i guess it is quite off topic but do anyone know a good site to stream newly released movies online?
@Hayes Jamie try Flixzone. Just search on google for it =)
@Landon Jay definitely, I've been watching on FlixZone for years myself =)
@Landon Jay Thanks, I went there and it seems to work :D I really appreciate it!!
Sir could you please share this lecture note? Please sir 😇 It was awesome lecture
It's on my website
@@Biochemistrybasics which text book sir
@@monishads9213 it's mention at the end of the video
