This is a specific response because in order to fight antigens, white blood cells, the most important cells of the immune system, must produce large, Y-shaped proteins known as antibodies to fight these invaders.

"what is total volume of the gas-exchanging region of the lungs?"

MrMuchimi

The total volume of the gas-exchanging region in the lung is called alveolar volume.

The alveolus is an air sack-like organ in the end of the respiratory airway. The alveolus is the site where gas-exchanging happens, so only air inside alveolus that will undergo actual exchange. Air in bronchus or trachea wouldn't do exchange

Energy Generation in Aerobic and Anaerobic Conditions

Ira Lisetskai [31]

I wanted to be with you alone

And talk about the weather

But traditions I can trace against the child in your face

Won't escape my attention

You keep your distance via the system of touch

And gentle persuasion

I'm lost in admiration, could I need you this much?

Oh, you're wasting my time

You're just, just, just wasting time

Something happens and I'm head over heels

I never find out until I'm head over heels

Something happens and I'm head over heels

Ah, don't take my heart, don't break my heart

Don't, don't, don't throw it away
