trachea
When we inhale air from the environment first enters the nasal cavity.Then it enters wind pipe to bronchi to bronchi-oles to alveoli.Alveoli are the terminal units of the lungs.
mouth and nose
nose or mouth
lung
Air enters the body when you inhale (Breathe in) air enters through the mouth and into the lungs. and then exhale (Breathe out) carbon dioxide (CO2)
No, bronchi is a passage of airway in the respiratory tract that conducts air into the lungs. No gas exchange takes place in this part of the lungs.
we inhale oxygen and exhale carbon dioxide. Oxygen enters the respiratory system through the mouth and the nose then to larynx-trachea- bronchi-bronchial tubes-lungs-alveoli-diffuses through the capillaries into the arterial blood, veins releases its carbon dioxide into the alveoli, then the carbon dioxide follows the same path out of the lungs when you exhale.
Air goes through the nostrils-pharynx-trachea-bronchus-bronchi(left and right) through bronchioles that keep branching, eventually to the alveoli. Alveoli are small sacs with a thin single cell layer. They are surrounded by capillary beds. Here, the oxygen diffuses into the capillaries and carbon dioxides diffuses into the alveoli. Oxygen enters the blood and CO2 is exhaled.diffusionrespiratoryAnswerHumans inhale oxygen and exhale carbon dioxide. Plants inhale carbon dioxide and exhale oxygen. Circle of life.
Mouth/nose, pharynx, larynx, trachea, bronchi, bronchioles, alveoli and capillaries.
Air is a mixture of gases.When we inhale we reduce pressure in our lungs and thus air is diffused in our lungs.This diffusion takes place inside the lungs and between the bronchities.Here the air passage is the trachea/wind pipe.
I smiled as I inhaled the beautiful rose scent. As you inhale, air enters your body. If you wear a mask, you won't inhale the toxic fumes. Smoke can kill those who inhale it.
The Process of the Respiratory System I am a Respiratory Therapist, so this is easy for me. During inspiration, air(gas) enters either through the nose or the mouth. As the air reaches the throat it becomes warmed and humidified and then passes into the trachea. It follows the trachea down into the bronchi then to the bronchioles(smaller versions of the bronchi) then into the alveoli. The alveoli are tiny sacs at the end of the bronchioles that look like clusters of grapes. After the air(gas) enters the alveoli, the oxygen from the air crosses the alveolar-capillary membrane and enters the blood. The blood then carries the oxygen to the organs of the body. During expiration, as the oxygen in the alveoli is entering the blood, carbon dioxide leaves the blood, enters the alveoli and is breathed out.
