Air enters trachea (wind pipe) via nostrils. From trechea it goes into left and right bronchus. It is then channeled into progressively narrower channels and finally it reaches alveoli where gaseous exchange occurs. This whole event is assisted by movement of diaphragm and of ribs.
What else can I help you with?
What is the path of air from outside of the body to the location where oxygen and carbon dioxide are exchanged?
Air enters the body through the nose or mouth, travels down the trachea into the bronchial tubes, and finally reaches the alveoli in the lungs where gas exchange occurs. Oxygen is absorbed into the bloodstream from the alveoli, and carbon dioxide is released from the bloodstream into the alveoli to be exhaled.
Describe the path that a molecule of oxygen takes as it moves form the air outside your body into the alveolar?
A molecule of oxygen enters the body through the nose or mouth, travels down the trachea, passes through the bronchi and bronchioles, and finally reaches the alveoli in the lungs where oxygen diffuses into the bloodstream through the thin walls of the alveoli.
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.
What is the path of an oxygen molecule when it enters the human body?
Nostrils-Pharynx-Trachea(Wind Pipe)-Bronchi-Bronchioles-Alveoli
What path does oxygen take throughout the body?
Oxygen enters the body through the respiratory system by inhaling air through the nose or mouth. It travels through the trachea, bronchi, and bronchioles to reach the alveoli in the lungs. From the alveoli, oxygen diffuses into the bloodstream and binds to hemoglobin in red blood cells. The oxygenated blood is then pumped by the heart to various tissues and organs in the body where it is used for cellular respiration.
Do alveoli have C shaped rings around them?
Alveoli are surrounded by capillaries so that the oxygen can diffuse into the blood and carbon dioxide can diffuse out. I think it depends on the shape of the alveoli to the path of the capillary.
What path does oxygen take as it enters the body?
Oxygen enters the body through the mouth or nose and travels down the trachea into the bronchial tubes, which then lead to the lungs. In the lungs, oxygen diffuses across the alveoli walls into the bloodstream where it binds to hemoglobin in red blood cells. The oxygen-rich blood is then pumped by the heart to the rest of the body's tissues and organs.
Is the alveoli comprised of millions of cells?
No, alveoli consist of flattened epithelial cells which make the diffusion rate faster (by the reducing the distance the path that oxygen has to diffuse through).
What is the process of oxygen flowing through the alveoli's walls?
The answer is diffusion. 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.
Which sequence correctly shows the path of carbon dioxide respiration?
body cells, capillaries, alveoli
How will you describe the path way of oxygen and the breathing system?
Oxygen enters the body through the nose or mouth, then travels down the trachea into the lungs via the bronchial tubes. In the lungs, oxygen is exchanged with carbon dioxide in the alveoli, where it is absorbed into the bloodstream. The oxygen-rich blood is then pumped by the heart to the rest of the body's cells and tissues for energy production.
What is the path that a molecule of oxygen takes as it moves from the air outside into the alveoli?
Oro (or Naso)Pharynx, Palate, Pharynx. Epiglottis, Hypopharynx, Larynx. Trachea, Carina, Right or left mainstem bronchus. Bronchi, Bronchioles, Alveoli. If you are using a textbook for a course, the terms may be a little different than what I have listed here.
