Please describe how human breathe including the following terms:?

Question

include the terms diffusion, aveoli, capillaries, diaphragm, intercostal muscles, CO2, breathing rate O2, hemoglobin, brain stem, pH, carbonic acid, thoracic cavity, trachea, bronchiole, and lung.

Once again, knee deep in homework and no relief in sight.....appreciate the help!

lol....tell that to my biology teacher

Answer 1

The primary function of the respiratory system is to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body. The respiratory system does this through breathing. When we breathe, we inhale oxygen and exhale carbon dioxide. This exchange of gases is the respiratory system's means of getting oxygen to the blood.

Respiration is achieved through the mouth, nose, trachea, lungs, and diaphragm. Oxygen enters the respiratory system through the mouth and the nose. The oxygen then passes through the larynx (where speech sounds are produced) and the trachea which is a tube that enters the chest cavity. In the chest cavity, the trachea splits into two smaller tubes called the bronchi. Each bronchus then divides again forming the bronchial tubes. The bronchial tubes lead directly into the lungs where they divide into many smaller tubes which connect to tiny sacs called alveoli. The average adult's lungs contain about 600 million of these spongy, air-filled sacs that are surrounded by capillaries. The inhaled oxygen passes into the alveoli and then diffuses through the capillaries into the arterial blood. Meanwhile, the waste-rich blood from the veins releases its carbon dioxide into the alveoli. The carbon dioxide follows the same path out of the lungs when you exhale.

The diaphragm's job is to help pump the carbon dioxide out of the lungs and pull the oxygen into the lungs. The diaphragm is a sheet of muscles that lies across the bottom of the chest cavity. As the diaphragm contracts and relaxes, breathing takes place. When the diaphragm contracts, oxygen is pulled into the lungs. When the diaphragm relaxes, carbon dioxide is pumped out of the lungs.

This was to long so here is the site

I don't know exactly what you wanted but here are some sites that should help. I went through nursing school and I know that the homework sucks.

Answer 2

You have presented a huge list of terms. Description of these terms can fill several books. Go get a personal tutor or a senior to help you out. no one can describe whole respiratory system here

Answer 3

Aren't you ashemed to ask someone else to do your homework for you? girl go ahead and read your book you will find the answer there1
