Their principal function is to transport oxygen from the atmosphere into the bloodstream, and to release carbon dioxide from the bloodstream into the atmosphere. This exchange of gases is accomplished in the mosaic of specialized cells that form millions of tiny, exceptionally thin-walled air sacs called alvioli

Hollow areas in the heart that receive incoming blood from the lungs and ship it out again?
Hollow areas in the heart that receive incoming blood from the lungs and ship it out again are called chambers. The human heart has four chambers.
How many lungs are in the body?
A human body only has 2 lungs inside a part of your ribs called a ribcage. That's where your lungs are located in your body.
What is the hollow space inside the head where air is warmed before entering the lungs and where nerves that detect smells are located?
The sinuses.
What is inside a snake?
A heart, lungs, liver, kidneys, stomach, intestines, bladder, bowel, brain - and a skeleton of around 800 bones !
Are lungs hollow or spongy?
Spongy.
How are the lungs designed in human beings to maximise the area for exchange of gases.?
Lungs consist of a series of tubes of ever-decreasing size, which carry air to and from the blood at the gas exchange surface in the 'alveoli'. These alveoli are microscopic hollow balls (at the ends of thousands of tubes) which are covered on the outside by blood capillaries (extremely narrow blood vessels) and a thin layer of mucus on the inside, which increases the speed at which the air diffuses into and out of the blood. The spherical shape of the alveoli, the microscopic width of these hollow balls (allowing more to fit within a small space) and the density of blood vessels inside the lungs all maximise the surface area. A last, important note: the lungs are NOT 'designed'; human lungs have evolved from simple gas exchange organs like the lungs of lungfish, becoming increasingly complex over a very long period of time.
When was Inside the Hollow created?
Inside the Hollow was created on 2006-08-29.
How our lungs work?
Our lungs are part of the human respitory system. The exchange of gases from the outside of the body to the inside of the body take place in the here.
Why do human beings cannot breath inside the water?
There isn't any oxygen to fill your lungs with.
In humans respiration takes place in the?

Is the lungs in the front or the back of the ribs?
