When oxygen is being carried back to blood cells?
Oxygen is transferred to blood cells in the capillaries around the alveoli. It diffuses from the alveoli into the bloodstream, and to the hemoglobin molecule.
What is the pathway of an oxygen molecule from the atmosphere to its combination with a hemoglobin molecule?
Oxygen reaches the hemoglobin in the blood cells by entering the lungs. The key area of the lungs where the transfer of oxygen and carbon dioxide is made is called the alveoli. The Alveoli has very thin cell walls which allow oxygen and carbon dioxide to pass freely in and out of the blood stream.
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 is the path of an oxygen molecule when it enters the human body?
Nostrils-Pharynx-Trachea(Wind Pipe)-Bronchi-Bronchioles-Alveoli
What gas enters the alveoli?
Oxygen is removed from the alveoli by the cappillaries.
Oxygen diffuse into the blood at the alveoli?
Carbon dioxide does.
Why oxygen diffuses from the alveoli into the blood?
Oxygen diffuses from the alveoli into the blood because of a concentration gradient. The partial pressure of oxygen in the alveoli is higher than in the blood, so oxygen moves across the thin membrane of the alveoli into the blood to reach equilibrium.
How can the oxygen you bring into your body get to your circulatory system?
your lungs have structures called alveoli. The alveoli are surrounded by capillary beds which carry blood. The oxygen enters the alveoli when you inhale. The oxygen then diffuses from high concentration in your alveoli to low concentration the blood in the capillaries surrounding the alveoli.
Where is the oxygen in greater concentrations in the alveoli or in the blood?
alveoli son..
How does partial pressure affect the movement of oxygen from the alveoli to the blood?
Partial pressure affects the movement of oxygen from the alveoli to the blood because it is the main driving force for oxygen movement in the lungs.Oxygen passes from the air to the fluid within the alveoli, into the cell of the alveoli.
What does the Alveoli and the capillaires do?
Alveoli takes oxygen in and brings out carbon dioxide.
Does oxygen move from the alveoli into the bloodstream?
i dont noww , alveoli is stupid
