Alveoli
Alveoli are the small air bags present in lungs that help in gaseous exchange.

Can you simply drain a clothes washer through an outside wall and onto the ground?
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.
How are the gills of a fish the same as alveoli?
The gills of a fish are like alveoli in that they give oxygen to blood and take the carbon dioxide from the blood along with other nutrients in the water. The alveoli in humans do the same thing except for they give nutrients fromt he air.
What are the similarities between the villi and the alveoli?
To understand the structural similarities, one has to understand the functional similarities. The most obvious similarity is that they are both involved with transport via diffusion. So the structural similarities would be those that facilitate this. eg. thin epithelium, large blood supply.
Is a mixtures of oxygenated blood with some deoxygenated blood. It results in reduction of arterial PO2 by 2mmHg and reduction of arterial oxygen saturation by 0.5% compared to oxygenated blood coming from alveolar capillaries
Gaseous exchange takes place in the alveoli where carbon dioxide from the bloodstream diffuses into the air.
What is the route taken by oxygen particles when they pass into the mouth and travel to the cells?
They pass through mouth to the pharynx which is connected with trachea
What commonly causes fluid on the right lung?
had pain in right lung,had xray and anti biotics amoxicillan,pain gone but lung feels slightly gravely
Why do leaves have a large surface area?
Leaves are broad, thin and flat to provide a large surface area, to absorb sunlight for photosynthesis. :)
What happens when blood reaches the vein?
Blood flows through veins after delivering oxygen to the body.
How the purge-dip system works by refering to the concept of hydrostatic pressure?

Why does surfactant reduce surface tension?
It prevents a pleural friction rub. Its like a lubricant for the lungs to move up and down without any friction.
At the peak of the inspiratory phase the alveoli contain how much of oxygen and carbon dioxide?
More oxygen than carbon dioxide.
Alveoli.
How co2 particles move from the blood to the alveoli?
They diffuse through the membrane.
Diffusion is the movement of gaseous particles from a high concentration of particles, to a low concentration.
Using your example of CO2, there is a high ammount of CO2 in de-oxygenated blood, so it travels to the alveoli through the membranes, where there is a lower concentration of CO2.
Remember, near every alveoli there is a capillary, which makes this possible.
