Sir,
PDF bhi dijiye is lecture ka batch me
In Q18 Ncert says antero-posterior axis
In 17 exhalation + pressure and inhalation me to - pressure gradient hota ha an?
Sir, please recheck Q 21
Question no 17,
Exhalation occurs when pressure within lungs is more than the atmospheric air,, so there is positive pressure wrt to atmosphere in our lungs
Ya u r right
Um no. The direction of air is towards the side where there is -ve pressure gradient.
@@ankitapachung4408 don't get ittt
Airr moves from high pressure to low pressure
Exhalation occurs when pressure in lungs is more ,that means there is positive pressure in lungs at time of exhalation 🫁
🥺🥺
Yes you're right..
Question no 18, please check it again, according to NCERT
" Inspiration is initiated by the contraction of diaphragm which increases the volume of thoracic chamber in the antero-posterior axis"
Your concepts are not clear the meaning of axis is the line passing BOTH FROM ANTERIOR TO POSTERIORLY and in que only posterior is given which is wrong if it would not include only then statement would be correct
@@pranavsethi1904 yes agar posterior hota to bhi chl jata but only posterior n pura statement glt kr diya
@@pranavsethi1904 exactly
Then what will be the exact answer
3rd answer lgao bcz agr exam mei concept se jeyada ncert ki line schi maani jati hai so don't take risk ncert schi hai bss 🙂👍
I am yakeen 2.0 batch student
Amazing session sir thank you so much ♥️♥️♥️
Sir plzzz brahmashtra series ka pdf bhi upload Kara dijiye plzzzz sir 🙏🙏🙏🙏🙏
Ha sir plz plz 🙏🔥🙏🙏🙏🙏🙏🙏🙏🙏🙏
Ha sir
28:17 Here ig it should be A as a positive gradient During expiration
How?? Can u pls explain me
@@niharjariwala07300 During inspiration negative pressure is developed via increament 8n thoracic cavity volume.But during expiration volume is reduced that increases the pressure in lungs than atmosphere which is a positive gradient
it's negative during inspiration
yes....I was searching for the same 😥 got it crct
Option 1
Ya option 1
Brahmastra series is very helpful sir ...... really need such videos 🥺❤️
🥰🥰
SIR IN QUESTION 21 IT WAS WRITTEN INSPIRATION AND U READ IT NORMAL EXPIRATION.
IN QUESTION 26 U HAD NOT COMPLETELY READ THE QUESTION IN WHICH ADULT MALE WAS WRITTEN.
IN QUESTION 31 IT WAS WRITTEN EXPANDED AND U READ IT EXPELLED.
NO DOUBT, THE SESSION WAS VERY INTERESTING,USEFUL FOR US.THIS SESSION SAYS US HOW ATTENTIVELY WE SHOULD READ NCERT. THANK U SO MUCH FOR THIS BRAHMASTRA SERIES.KINDLY CHECK THE ABOVE MENTIONED QUESTIONS

Sir Kamal hai
Q16.According to ncert inspiration ke time negative pressure hoga toh expiration time automatically positive pressure hojayeya!!
Q. 17 bhi same explanation
Q. 18 increases in antero-posterior axis NCERT LINE!!
Q 21. Both a and b are correct 🥲
Q31. Option 1 according to ncert
Yss
antero posterior axis hai yr but posterior part me volume bdhta hai ncert ki line bilkul rat mt lo smjho concept brother
Q.4 - isn't 2 correct?

Q 21 A/c to ncert We have the ability to increase the strength of inspiration and expiration with help of additional muscles in the abdomen
For question 21, it is given in ncert pg no.271 that "we have the ability to increase the strength of inspiration and expiration with the help of additional muscles in the abdomen". In that case the answer should be (2) ?
Ha yrr mai bhi confuse hu
Yess.... It should be( 2)
sir lecture ka pdf note provide kara dijiye please....and by the way sir thank u for this awesome session ...pura ncert revise hogaya aur concept ek dum BRAIN MEIN SET ho gaya
Question no 31 according to NCERT 1st statement is correct 💯💯💯💯💯💯
yes.............................
Absolutely ...sir ne expand ko expell padh liya
Absolutely....sir ne galti se question ko galat padh liya
sir in ques 17 ans should be option 1 because intrapulmonary pressure is negative during INSPIRATION but positive during EXPIRATION and the assertion has stated about expiration ...so technically answer should be 1... sir i alao hv doubt in quex 35
Correct option should be 2
Because for this reason should be during exhalation there is high pressure in lungs as compared to atmospheric air and air moves from high to low pressure
Correct me if I am wrong
@@pokegamer4403 but positive pressure means the same bro
Sir in question no. 17 exhalation is carried during positive pressure in lungs whereas during inspiration there is negative pressure in lungs
Then answer should be 1 n🤔?
Yes
48/52 THANKYOU MY FAVOURITE SIR❤️✨
58:33 sir 2 option hoga na bcoz blood aur tissues ke bich exchange kyu hota hai iska explanation to nahi diya hai bus process passive hai bata diya agar process passive na batake pressure difference ki baat karta tab na reason correct explanation hota, simple diffusion of gas to kahi bhi hoti hai likin blood aur tissues ke bich kyu hoti hai iska answer nhi mil rha na, please correct me 😞
Amazing 😀 session
Crystal clear
MD sir=Concept of bio
Who one agree's?
#*PWkaisaareTeacherAwesomeHai*..
Great lecture really enjoyed and revised almost the entire chapter just some pathology and remaining stuff was left that much we could handle by our own thank you sir your energy motivates me to study even harder
NOTE:-Q.53 is not removed from syllabus because it is given in 12th ncert microbes in human welfare and answer of that que is vitamin B12 (option1)
Thank you so much 🎉
Question no 18
NCERT me antero - posterior diya hai .
Sir question no -17 me doubt hai sir air high pressure to low pressure move Karti hai na to during exhalation pulmonary pressure atmospheric pressure se jyada hoga (means- positive pressure hona chahiye na ) tabhi to air release hogi or negative pressure to inhalation me hota hai??????????¿ Please sir reply ☺️🥺🥺🥺🥺🥺🥺🥺
Sir please discuss Q.31 also in next session.
Statement l mei ' expanded ' hai ( not expelled )
TV, ERV and RV to already lungs me hai. IRV lene ke baad lungs me maximum expansion ho jaega i.e., TLC.
Thank you sir 🙏🙏🙏
same doubt
Q.18 is wrong option 2 is correct NCERT page 270 last third line
Yes sir please try to convince others teachers also to conduct this type of lecture. It is really helpful
Question 16
Both are correct
Because
The pressure gradient is negative during inhalation and positive during exhalation.
Yeah u are right
Ques-21 : NCERT says "we have the ability to increase the strength of INSPIRATION and EXPIRATION with the help of additional muscles in the abdomen."
Ques-31 : *Expelled* nhi "Expanded" hai na wo...
Sir in question number 18 answer should be 3 because in ncert it is clearly mentioned that increases in anterio posterior direction.....
Q31 ka 1st hona chaiye.... ? 1st bhi to correct h
For question 18,
NCERT mein mechanism of breathing ke last third line mein likha hua h ki - “Inspiration is initiated by contraction of diaphragm which increases the volume of the thoracic cavity in the anterio-posterior axis.”
Ha
Haaan sir se mistake ho gyi h
Hn yhi mai pdrhi thi
Sir sach m maza aa gya . dropper ke liye aese session bhut hi imp hai sir.. Puri ncert ki lines revise ho rhi h .. Thanku sir aese osm session ke liye aar apke efforts ke liye jitna thanks kre kam hai 😊
Sir in question 31 answer should be option 1 ... 56:58 Since it's written that TLC IS THE MAXIMUM VOLUME TO WHICH LUNGS CAN BE EXPANDED TO THE GREATEST POSSIBLE EFFORT At RHE END OF FORCED INSPIRATION.
Haa
Miss You Sir ...❤🥺
3:00 missing those days😢❤
Plzzz provide PDF sir✨...so that we again practice the AR type of questions and CI type of questions
Yes Bhai
Bhai screen shot lekar ek pdf khud bana lo naah..! 😅😅
21 no problem mein according to ncert the ability to increase the strength of inspiration and expiration with the help of additional mussels in the obdomin mentioned haii
Sir please 17,18 question please check it again your session is very helpful thank you so much sir 🥰🥰❤️❤️❤️❤️🙏🙏🙏🙏
I also felt that
41:08 sir 21 ka 2 ans he ncert me dono ka likha he
SIR IT HELPS US ALOT .
THE QUESTIONS YOU FRAME ARE EXACTLY SAME AS IN 2022
THANK YOU SIR
17th question.. Both the statements are crrct... Option :A
BMS 🧠💯 brahmastra series is very helpful... amazing session
Sir in ques 17 2nd statement can be right because in ncert it is given that during inspiration there is a negative pressure in lungs so indirectly their will be positive pressure in lungs during expiration???
Questions 17 reason can be correct becoz... expiration me volume dec but pressure increase so we can say it positive in comparison to atmosphere
Hmm u are right, i also noticed this.
👍
20:58
Aapne bahut achha kiya ye batake guruji
Mujhe confusion tha ki 300 million alveoli present in each lung or both
But jb me Google kiya to shocked ho gya 🤐
Sir is besttttttttt we cant impress how he is a good teacher
In NCERT .,, we have ability to increase.the strength of inspiration and expiration with the help of additional muscle in abdomen Q21 me 1st incorrect kase h
Sir 🧠 me set hogya (bms)
Bramhastra series is amazing 👏👏
Outstanding super level content 💯💯💯💯💯💯💯
Sir❤️Q18 according to NCERT:-contraction of diaphragm which increases the volume of thoracic chamber in the anteri-posterior axis..???🙄
thank you sir
this is an amazing series please never end it until our exam 😍
In question no 18 ...sir ncert m anterior and posterior dono axis mention h ...
@Competition_Wallah
Sir the answer of questions no 17. Has to be A
As if we are talking about the pressure gradiant between lungs and atmosphere then it will give a positive integer which is +2 but for P.G between atmosphere and lungs it will be -2........
Sir in question 31 pls see there is expanded as compared to expelled therefore the answer should be option1 pls check
The session was very helpful from Arjuna neet 1
Sir ji 🙏
Question no. 17 ko ek baar check kriyega phir se
Kyuki usme Assertion me diya hai ki Air lung se bahar nikal rhi hai!!!
Aur Reason me diya hai due to positive pressure gradient !!
To isme both correct and reason is correct explanation of assertion hoga.
Check krke bta dijiyega..
Aapka Ykeenian 😊
Start at 4:16🙏🏻🙏🏻
Tnq sir 🫀🙏✍️🔥😇
Full BMS 🧠
Yakeen 2.0 💫💯
Sir que no. 18 mai statment -2 ka NCERT ka according incorrect hoga
Haan mujhe bhi wahi lagta h
sir question no. 17 me reason bhi correct h or answer 1 option aayega because (((( inspiration negative pressure ki wjh se hota h or expiration me positive pressure hoga )))) kyunki ques. me between lungs and atmosphere likha hua h to lungs ka pressure jyada hota h or atmosphere ka kam hota h isliye positive pressure gradient ban gaya na sir ji
ques. 31 bhi glt bataya h sir 1 option aayega sir 👍
No words for true and real hero of all students ❤️❤️ guru ji❤️❤️
Sir 21 question ka answer 2 hoga both are correct "NCERT" 42:42

Sir qn no. 16 me breathing k respect m pucha hai ..
To breathing m expiration and inspiration dono ayenge , jisme ek me negative pressure hoga or ek me positive pressure hoga to sir ans . Dono hi ho skte h
Question 27 is it that TV = 500 ml in adult male? And what if women written in place of male? We have to consider it right or wrong?

Q17 is wrong ..bcz in ncert it is clearly mentioned negative pressure gradient only when inspiration is occurring..
In expiration intra pulmonary press is higher than atm pressure..
Also in Q21 , ans should be option 2 ..as per ncert .. we can increase strength of inspiration and expiration with the help of additional muscle present in abdomen .
Q31 , statement 1 is right .. the same statement is given in ncert .. so ans should be option 1
29 question is right.... Check video properly

Sir please continue brahamastra 🙏🙏🙏🙏
Thankx a lot sir for your efforts ❤
Isn't it that ans for 18 question is (3) bcz diaphragm increase volume in both anterior and posterior axis? Please tell 😊
Yes
According to NCERT diaphragm increases volume in anterio-posterior axis it means that it increases the volume from anterior axis to the posterior axis
So 2nd is correct
Another explanation is that diaphragm can only move in anterior and posterior axis but when its move in anterior axis volume decreases and question is asking about the increase in volume so volume increases when diphragm moves in posterior axis
@@soulLunoX thankx a lot, stay blessed🙏
Sir Q23 me woh pulling kaise hoga !! As that air is preventing the lungs to collapse so it should be pushing rather than pulling !! Acc to alakh sir's phy 😄😄
