Respiratory System

pharynx, larynx, trachea, bronchi, bronchioles, alveoli

No. It is an autonomic reflex. You brain doesn't even resister that you sneezed for a millisecond after it happened.

its in the middle of your upper chest.. mostly including your lungs :)

Starting from the left and right bronchi, bronchus for singular, these branch down from the trachea. Then the bronchi branch off to smaller bronchi and these branch off to bronchioles. The bronchioles contain air sacs at the end called alveoli and alveolus for singular.

Many things are important, among them include a good diet, and plenty of rest.

"most important" is carbon dioxide

also oxygen and H+ concentration

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.

Inhalation means breathing in, and exhalation is breathing out.

Images of the human respiratory system can be viewed on several websites. Among these is Teach PE. Google Images also has many images of the human respiratory system.

Your respiratory system draws in air, which is vital to life. However, the circulatory system gets the air to where it needs to go.
A respiratory system is used to draw oxygen into the lungs. The circulatory system, however, sends the oxygen to where it needs to go.
Transports Oxygen, minerals and proteins to the cells and organs that require them in order to respire and remove wastes generated by respiration such as carbon dioxide, lactic acid in the case of muscles etc.

breathing

*IT* Doesnt

Emphyesma is when alveoli die.

how does it affect them...

Well it would affect them like it affects every other cell in the body.

(decreased O2)

but it acually doesnt affect the alveoli

it just happens

when they die

Human body hair might seem to be useless on today's modern man, but it could help us detect parasites, researchers suggest, adding there's a chance our female ancestors preferred a bug-free mate, and so opted for hairier guys.

the oxygen we inhale will reach lungs . the hemoglobin will bind with oxygen through iron present in hemoglobin as (Fe2+).and it will reach blood cells. the myoglobin present in the cells will bind with the oxygen which is already bonded with the hemoglobin. coz myoglobin have greater affinity than hemoglobin.then hemoglobin picks up co2 from myoglobin will reach lungs ,finally we exhale.

In fast twitch muscles.Aerobic respiration occurs in the mitochondria.

cardiac output can be determined by the following formula

Me and your mother had sex last night it was the best

its false

While exercising the muscles use oxygen and produce carbon dioxide. The lungs and heart respond by supplying extra oxygen. Breathing increases and you breath deeper to maximize intake. Heart rate increase to transport the oxygenated blood to the muscle.

To allow the air to enter the body. The air can enter through either the nose or through the mouth.

The diaphragm below the lungs, which one of the body's strongest muscles, lowers and raises again, drawing air into the lungs and pushing it back out again. "Hiccups" (hiccoughs) are caused when a stimulus of the vagus nerve triggers a sudden lowering of the diaphragm, drawing air in and forcing the vocal cords closed in the larynx.

The nasal cavity

so that they can breath. If you do not know the respiratory system is used for breathing
