What sequence correctly shows the path of carbon dioxide during respiration?
External respiration is the exchange of oxygen and carbon dioxide between the lungs, body and the outside environment; the breathing process known as inhalation and exhalation. Upon inhalation, air enters the body and is warmed, moistened, and filtered as it passes to the alveoli of the lungs. Oxygen diffuses from the alveoli to the bloodstream, then into the red blood cells. Simultaneously, carbon dioxide in the blood is diffused from the blood to the alveoli, and exhalation expels the carbon dioxide from the alveoli.
How do alveoli work?
The alveoli are located in the lungs. They are used to move carbon dioxide and oxygen between the lungs and the bloodstream.
Why are people with emphysema more weak then others?
Emphysema is a long-term, progressive disease of the lungs that primarily causes shortness of breath due to over-inflation of the alveoli (air sacs in the lung). In people with emphysema, the lung tissue involved in exchange of gases (oxygen and carbon dioxide) is impaired or destroyed. Emphysema is included in a group of diseases called chronic obstructive pulmonary disease or COPD (pulmonary refers to the lungs). Emphysema is called an obstructive lung disease because airflow on exhalation is slowed or stopped because over-inflated alveoli do not exchange gases when a person breaths due to little or no movement of gases out of the alveoli.
What happens in the alveoli-?
Gaseous exchange takes place in the alveoli where carbon dioxide from the bloodstream diffuses into the air.
What are the small air tubes that lead to the alveoli called?
The tubes that connect the bronchi with the alveoli are the bronchioles.
The surface tension exerted by water in the alveoli prevent collapse of the alveoli during exhalation?
False
Why do alveoli die in emphysema?
Destruction of alveoli reduces the surface area for gas exchange
What disease is referred to the destruction of the alveoli?
Emphysema.
What is a hyper aerated?
or hyperinflation it is where the lung volume is abnormally increased with increased filling of alveoli.
How can air pollution cause emphysema?
The dust particles comes from air pollution and the concentration of carbondioxide is higher in it...so,when they enter in human body it start the destruction of the walls of alveoli...and the low concentration of oxygen disturb the gaseous exchange between alveoli and the capillries... By this exhalation process can't be done..In sever cases it can cause death...

How does air move into the lungs during exhalation?
Nasal cavity Pharynx Larynx Trachea Bronchus Bronchioles Alveoli
Air is expelled from the alveoli during exhalation due to the effects of?
Air is expelled from the alveoli, as well as the lungs in general, during exhalation when the diaphragm relaxes and rises up. This creates pressure on the thoracic cavity, and since there is more air pressure inside than outside, the air is exhaled to relieve the pressure.
What is the destruction of alveoli due to age or by respiratory irritants called?
emphysema
What happens to the carbon dioxide in the blood when it flows through the capillares in the aveoli?
CO2 diffuses from the blood to the alveoli and the exhalation removes the CO2 from the body.
How do alveoli work?
The alveoli are located in the lungs. They are used to move carbon dioxide and oxygen between the lungs and the bloodstream.
Reduced gas diffusion because of the destruction of alveoli is a medical condition known as?
emphysema
