One way to expand your butt is too eat a lot of grass. Believe it or not, licking dog poo works as well. But some people take the simple route and just lick their own butt 5 times a day. it works like a charm.

By the way, why would you even want a big butt? Weirdo.

carbon dioxide

The larynx (voicebox) is responsible for speech in humans, due to vibrations from exhaled air.

a open type it is also a cold blooded animal it system is 5 chambered nd help it to circulation in blood.

Three factors are ideal for high gas exchange between bloodstream and alveoli: # Large surface area- Hundreds of thousands of alveoli, each one shaped as a spherical sac, increase the surface area massively to increase the volume gases that can be taken up. # Large concentration grad.- fast-moving blood flow maintains a steep conc. gradient. # Small diffusion distance-The distance for O2 and CO2 is roughly two cells thick ie. 40 micrometres.

Seasonal Affective Disorder

You know, the factors of partial pressure

it is tranfered through the alveoli to the red blood cells which Carrie it throughout the human body . when it gets back they remove the CO2 and send it back through the bronchials to be exhaled

Aveoli are part of your respitory system and are located in your lungs, and their function is to give Carbon Dioxide to your lungs (for you to exhale) and take Oxygen from your lungs (to give to the capillaries-your blood). So, the aveoli's, in a sense, filter your bloods oxygen.

Nephrons are part of the excretory system and are located in your kidneys. Their function is to filter your blood by taking out excess salts and waste. So, the nephrons also filter out your blood, but instead of filtering the gasses in your blood, the nephrons filter out the metabolic wastes.

A large surface area

Yes, Oxygen diffuses through the wall of the alveoli then through the walls of the capillaries. :)

pericadium

The round shape increases the contact surface area, so more air can be exchanged.

3oo million alveoli

gas exchanging

If we think of the lungs as trees branching out, the alveoli are at the end. They are made of up clusters of small delicate sacs. This is where the oxygen you breathe in seeps across into the blood and the carbon dioxide (a "waste product" of all the things the body makes and does) comes out of the blood (and is then breathed out). It is the delicate structure and nearness to the blood vessels that allow this passage of oxygen in and carbon dioxide out. Pretty cool!

The larynx or voice box provides a passage. but the alveoli help

The bronchi continue to divide into smaller and smaller branches until they end in air sacs. The air sacs in the lungs are called alveoli.

the walls of the alveoli are very thin but strong layers of elastic tissue lines with a single layer of flattened epithelium.

gas exchange is the intake of the oxygen and the let out of the carbon dioxide
