Respiratory System

Sham sham sham sham sham!

12 to 20 respiratory cycles per minute.

the digestive system is obliviously for breaking and digesting food whereas the respiratory system is for breathing

Its a simple fact that in order to live we have to get oxygen into our blood. To this effect we inhale air into our lungs. But that in itself is not enough. Somehow the body has to get the oxygen that is in the air into our blood and in sufficient quatity. To do this our lungs have, over millenia evolved. each lung contains millions of liitle air sacs that look like bunches of grapes. These little air sacs are called alveoli. They act to increase the surface area of each lung and therefore increase the amount of blood that can absorb oxygen in one breath.

Together, the millions of alveoli of the lungs form a surface of more than 100 square meters. Within the alveolar walls is a dense network of tiny blood vessels called capillaries. The extremely thin barrier between air in our lungs and the capillaries allows oxygen to move from air in the alveoli into the blood and allows carbon dioxide to move from the blood in the capillaries into the alveoli. Without them the lungs would have to be many times larger than they actually are to absorb the amount of oxygen the body needs.

The hair in the nasal cavity also known as cilia keeps dust and other impurities out of you nose.

mucus helps prevent dust from going into your body. mucus stops that dust or other things that try to get in. that's why it is recommended to breath through your nose and not through the mouth when not necessary.

The circulatory system and respiratory system work together to provide the body's cells with oxygen and to carry away the carbon dioxide that cells generate as respiratory waste. The respiratory system gets air into lungs and in the small air sacs were oxygen is transported into the blood, and the circulatory system carries the oxygen in the red blood cells and delivers it to cells in need of oxygen. The oxygen is stored in the hemoglobin in the blood, and the blood is pumped around the bodily organs by the heart, releasing oxygen at the organs.

Yes. It is what we do and one of the ways we have of surviving.

sometimes

· Our body's cell continually use o2 for metabolic reactions the release energy from nutrient molecules and produce ATP.

· At the same time, reaction release co2

· Because an excessive amount of co2 produces acidity must be eliminated quickly.

· Cvs and resp system cooperate to supply o2 and eliminate co2

· Resp system

o provides gas exchanges

o Intake of o2 and elimination of co2

· Cvs system transports blood containing the gases between the lung and body cells.

whats prevents food from going down your lungs

Nares are the external openings of the nose (human, animal, or reptile). These are also known as nostrils or the nasal passages.

respiration rate would increase in order to blow off co2

decreased pH, increased temperature or increased levels of CO2

Basically the same as in other mammals, Air is breathed into the lung from where oxygen is absorbed into the bloodstream used by the body where Carbon dioxide is produced as a result, The carbon dioxide is returned to the lungs and exhaled along with water vapor and some other gases. This is a very simplistic description.

aerobic respiration

Death.

You can see how the respiraotry system works.

year 8 kid

all Produce 2 ATP and all go through Glycolysis thats my guess.

The Pharynx.

Lactic acid and oxygen debt

It's not - germs are.

But anemia (moderately severe) means you have to increase your cardiac output to maintain oxygen demand - so a tired heart, a heavy lung all make it easier for disease to take foothold.

False

Air is forced into the lungs.
