How are the alveoli designed to maximize the exchange of gases ?
The bronchus, within the lungs, divides into smaller and smaller tubes (bronchioles) and finally terminates 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.
