Mam I have watched you for the first time and feel blessed to be your student. You are so real, a commedia and a kind hearted teacher, Who is passionate too.. Tq mam😊😊💐💐
I have done almost all my biology in class 12th from you and I was in love with your teaching style 💜and now also..... I was from a residential school(jnv) that's why due to lockdown I was able to learn from you. Now I am a dropper, and again when I see you, literally I get emotional 💗 Sachm wo puraane din yaad aa jaate h mam😓🤎
She lets you get addicted in what she teaches and the day whenever you'll complete a video of hers you will not be able to understand that much as easiest way from others as she teaches!!!!!🔥🔥🔥🔥
When i will crack neet and become a doctor you will always be a part of my life. Wonderful teacher. Amazing learining experince. Can't thank you more.✌✌😊😊

Very good.. Very great lecture.. Plse i haved one doubt... R. B. C mean red blood cells and R. B. C red blood corspule... What is the different... Hire cells, corspule... Y calling different name???? Any explian me
Why veins are blue bcoz... 1. Our blood is red bcoz of Hb.. and it is due to iron present in it.. In form of fe2+ 2. When oxygen reacts with fe2+ it forms fe2O3.. Which is bright red in colour.. 3.but when cells use that oxygen they again come back as fe2+.. Which is light green.. Bluish colour... It doesn't become completely blue or green but some amt of it... Bcoz of deoxygenation it's blood vessel looks blue. Neela bakore mam had explained it in her youtube channel...
Apko kbi kch n hoga mam🥺love uh so much...u r god of biology...36:00🤣🤣🤣mam....apki acting nd words...abi main apse kota m mili...we r blessed to hv uh as our bio teacher mam❤️
Veins appear blue because blue light is reflected back to our eyes. This may seem odd, since veins contain deep, dark red blood. There are several factors that lead to our seeing veins as blue rather than red. Blue light does not penetrate human tissue as deeply as red light does. As a result, veins that are close to the surface of the skin will be more likely to reflect blue light back to the eye.
Mam hb jb oxygen se react krega tbhi to red colour provide hoga blood ko.. otherwise jb ye oxygen se react nhi krega tb to ye purple colour provide krata h ...Qki jb koi prsn poison leta h tb wo blue ho jata h 🙄🙄🙄????
