H.W.ans. alveoli are balloon like structure which have thin walls and have lots of capillaries in it and as they are thin high in number which provides large surface area which maximises the exchange of gases

[@neelammaurya4555]

13:07
1) one cell thin walls[easily diffusion can take place]
2) balloon like in shaped [ more n more amount of O2 can be utilized for respiration
3) rich in supply of blood capillaries.

[@spifix22]

Alveoli designed to maximize the exchange of gases because rather than one big alveolus, millions of alveoli can increase the surface area for gaseous exchange and transportation of O2 can happen efficiently.

[@parthiban3074]

alveoli are designed to be in balloon shaped so that the area of gaseous exchange increases and also it becomes easier.

[@rohanpreetsingh9015]

Alveoli are balloon like in structure and have thin walls .
They are more in number which helps in high amount of exchange in gases
Thanks for the amazing session and for the fast-track Revision

[@yasin1622]

O2 is transported by RBC ... Which parts of the cell is responsible for transportation of carbon dioxide???

[@instadevi9876]

Blood capillaries

[@sruthi6236]

H.W.
The alveoli are balloon like structures which are filled with fine blood capillaries which help in the exchange of gases through the process of diffusion.

[@sruthi6236]

There are millions of alveoli which increase the surface area for exchange of gases.

[@holiday_hw_expert]

U know what maam actually tomorrow I have my pa1 of science and this video could be a savoir and a quick recaptulation video for me.
Thanks !

[@AyushKumar-wi3ue]

[@nisharajesh4798]

HOMEWORK ANSWER:-
In our body there are millions of alveoli and not just one big single alveoli this increases the surface area for gaseous exchange so that more oxygen can enter and can be transported to different parts of body.
Also alveoli contains blood capillaries for the diffusion of gases easily.

[@mithun-g2o]

❤🎉best s ssion ever. Thankyou aishwarya mam 🎉🎉

[@prabhusampath1764]

Alveoli are balloon shaped and have thin walls which facilitate the exchange of gases

[@vartikaarora4669]

Homework Ouestions
One Celled Thick
Large Surface Area
Supplied With Blood Vessels

[@JaiAditya-me1ql]

Alevoli is a sac like structure where exchange of gases takes place. It is surrounded by blood vessels where oxygen and carbon dioxide is exchanged.During this continuous process carbon dioxide is given out. It helps in increase the surface area.

[@Edit_foryou226]

alvioli are small sac like structures maximised in no. to increase the surface area for gaseous exchange they are heavily supplied by blood vessels and have thin walls for change of gasses in blood and alvioli

[@sikharanipradhan7733]

Thanks mam🥰🥰😍❤💝

[@Once_In_A_Blue_Moon111]

Alveoli are balloon like structures which are present at the end of bronchioles. They are millions in number and they are thin walled which contains blood capillaries which help in the diffusion of oxygen.This helps to maximize the exchange of gases.

[@udaychaubey1807]

I have a doubt.....
So why do the exchange of gases are simultaneously in alveolus but not separately if the co2 and oxygen are coming one by one??

[@parth1290]

'Each gas acts independently and diffuses down its own partial pressure gradient'.
A partial pressure gradient is the difference in the concentration of a gas in a mixture of gases, in which the gas is at a higher pressure in one location and a lower pressure in another location. A gas will diffuse from a higher pressure to a lower pressure down the gradient.
This is how oxygen and carbon dioxide diffuse into and out of our bodies.
Gas exchange occurs in the alveoli (air sacs) in our lungs, which contain capillaries. The partial pressure of oxygen is greater in the external environment than in the capillaries, so oxygen diffuses into the capillaries. The partial pressure of carbon dioxide is higher inside the capillaries than in the external environment, so carbon dioxide diffuses out of the capillaries.

[@by_justice242]

Hw: There are millions of alveoli which increase the rate or surface area for gaseous exchange. These alveoli are supplied with blood vessels which help in transporting of gases around in the body.
Thank you mam for covering this topic in such a short video. :)

[@jishnajnair7713]

Alveoli are balloon shaped to increases the surface area for gases exchange thereby maximizing the exchange of gases

[@shahidabano7171]

Alveoli have thin walls and a close network of blood arteries to allow gaseous exchange between blood and alveoli. They have a balloon-like structure to maximize surface area in exchange for gas.

[@dreammbbsaiims]

Very nice explanation mam😊

[@yaafiahkasim7902]

Millions of alveoli are present in our body........to increase the surface area of gaseous exchange , also alveoli has a thin layered covering and is a balloon like structure. they are well connected to the bloodstream

[@sakshi1121]

Thank u ma'am for this session😊
Answer of homework question
Alveoli are balloon in shape there are many alveoli in our lungs to increase area of respiration.
Thank u

[@Payal-7.08_]

Thank you so much mam😊💖...
Homework Q&A:
Alveoli have small sac like structure which helps in gas exchange. They have thin walls and are supplied with blood vessel for gaseous exchange between blood and air filled alveoli. They have balloon like structure to maximize surface area in exchange for gas.

[@divaj477]

Hw answer
The bronchi within the lungs divide into smaller tubes called bronchioles and finally terminate in balloon like structures called alveoli the alveoli are made up of thin moist membranes which are richly supplied with blood and provide a very large surface area for the gaseous exchange

[@user-vb5re3ll5x]

Thank you mam for saving my time❤

[@SUGUNAAYINAVILLI-or2eh]

While exchanging of gases increased

[@tinagaur7838]

What is buccal cavity?

[@rameshpalagiri742]

Plzzz provid the notes link medam

[@ShouryaKumarSingh]

Krish a ❤

[@rajeswari960]

Mam do part 3 in geography chapter 1 for class 10

[@Sathwik_shyamsunder314]

They have a balloon like structure

[@Kiranshree-nm1iv]

Mam plese teach the full chapter as usual u take 2 hour detailly

[@kriti12309]

Thanku mam 💫✨💫

[@DivyanshuJha-fg6ob]

Alveoli are balloons shaped so that surface area increases and gaseous exchange becomes easy
The session was amazing as always it was really helpful

[@tinagaur7838]

Hello mam

[@mohammadsuhail7471]

Very irritating lecturing

[@Pihu_449]

Kis kisko ye lecture dekhne ke phle lagta tha ki respiration mtlb Breathing Hi hota hai😆

[@Muskanyadav98126]

Mughe😮

[@zoya438]

Why we think that it is breathing 😂
