Alveoli are similar to cells in the sense that they have a large surface area to volume ratio. This is advantageous since they depend on there surface to allow as much oxygen as possible to diffuse through.

Therefore, the correct answer would be something like this :

Since alveoli's have a large surface area to volume ratio, it oxygen to diffuse through. More oxygen can be absorbed. If the alveoli had a smaller surface area to volume ratio, it would be very difficult for oxygen to diffuse through. Therefore, it is advantageous for the alveoli to be small in volume, but great in surface area.

Gas is exchanged by diffusion.

We have followed the path of the air and of the oxygen into the bloodstream. But breathing is a two-way street: we breathe in and then we breathe out. When we breathe in, or inhale, oxygen is removed from the air. Breathing also removes waste from the lungs and from our noses and mouths. How does this waste material get into the air that we breathe out, or exhale?

The thin walls of the alveoli actually have two purposes. When we breathe in, oxygen passes through the walls of the alveoli and into the blood. Carbon dioxide and water vapor then travel the opposite direction. They are the main waste products that pass from the blood vessels (arteries) in the lungs, into the alveoli, through the windpipe and out the nose and mouth.

In the alveoli, oxygen crosses over into the blood stream and carbon dioxide leaves the blood stream and enters the alveoli to be expelled through the lungs.

We breath in oxygen then it travels through the respiratory system ending to alveoli. Oxygen passes through the blood stream by using capillaries as a place to swap with carbon dioxide so that the alveoli gets the oxygen. Then the carbon dioxide leaves the body when we exhale.

They increase the surface area and hence the rate of reaction is increased...

So gas exchange can be much quicker, especially as the bloodstream flows very close to them

A small percentage of babies are born with one lung. This can result from birth defects such as congenital diaphragmatic hernia, where the diaphragm is incompletely formed.

The condition is not uniformly fatal, except where the lung is not the only organ with a serious defect (heart, liver, kidneys). Many children who survive infancy with one lung can lead normal, active lives. There are usually medical problems that can be worsened, however, in the absence of two complete functioning lungs.

Conjoined twins are often separated, and in some cases may have only one lung each after surgery.

My grandmother's house used to have drainage for her washer that was piped out of the house and onto the ground. She lived on a farm with a well, so there were no city ordinanced regarding water. Problems with this that I can think of as a non-professional: 1) The water might run close to the house and cause water to pool close to the foundation causing flooding issues. 2) Substances on clothes (any oils, chemicals, etc.) could go directly into ground water and grass unfiltered. I'd call a pro and ask about this one.

The verb to seize means to grab and hold.

Example:

"I pulled away before he could seize the phone from me."

"The enemy troops prepared to seize the city."

"Moving parts will often seize, or become stuck together, unless lubricated."

Expiratory reserve volume is decreased in a patient with emphysema. This patient will struggle to breathe out because air is getting trapped within the lungs. There is also an increase of co2 in the blood because of the inability for the patient to exhale.
