Where does the exchange of oxygen and carbon dioxide between the air and blood occur in humans?
The exchange of oxygen and carbon dioxide between the air and blood occurs in the alveoli of the lungs. Oxygen from the air diffuses into the blood in the capillaries surrounding the alveoli, while carbon dioxide from the blood diffuses into the alveoli to be exhaled.
A drop of blood is releasing oxygen and picking up carbon dioxide what type of blood vessel does this occur in?
capillaries
Why does exhalation occur in the human body?
To remove Carbon Dioxide which is dissolved in our blood stream. Dissolved Carbon Dioxide forms Carbonic Acid which is toxic to us.
Why does tachycardia occur w asthma?
fast breathing rate In asthma or other lung diseases, the ability to expire carbon dioxide decreases, resulting in buildup of carbon dioxide in the blood, resulting in respiratory acidosis (decreased pH in the blood). Acidosis stimulates the respiratory centers in the brain, causing the respiratory rate to increase (tachypnea) to attempt to normalize the pH of the blood.
Where does the diffusion of oxygen and carbon dioxide occur?
In the lungs, the diffusion of oxygen occurs from the alveoli (air sacs) into the blood capillaries, while the diffusion of carbon dioxide occurs from the blood capillaries into the alveoli for exhalation. This exchange process is facilitated by differences in partial pressures of oxygen and carbon dioxide between the air in the alveoli and the blood in the capillaries.
What happens when carbon dioxide levels in the blood increases?
When carbon dioxide levels in the blood are too low hyperventilation can occur. Hyperventilation can have voluntary or involuntary causes.
What is the medical term meaning lack of carbon dioxide?
Acapnia is the medical term meaning lack of carbon dioxide
Why does pulse rate go up with exercise?
Exercise causes an increase in carbon dioxide in the blood. The raise in carbon dioxide alerts the respiratory center in the brain, which then causes the lungs to breathe harder/faster in order to keep a good balance of oxygen and carbon dioxide. The exchange of carbon dioxide and oxygen occur in the alveoli in the lungs by the process of diffusion. Since the heart and lungs function together, the heart must pump blood faster to keep up with the needs of the lungs. The blood must be oxidized faster, so the heart makes the blood flow faster throughout the body so the lungs can put oxygen in the blood and the carbon dioxide can be expelled.
When oxygen is produced more than carbon dioxide?
When oxygen is produced more than carbon dioxide, it leads to an increase in oxygen levels in the atmosphere. This can occur during processes like photosynthesis in plants, which convert carbon dioxide into oxygen. The excess oxygen can benefit organisms that rely on it for respiration.
What gas leaves the blood in pulmonary capillaries and enters the alveoli?
carbon dioxide
When does aerobic occur?
in the presence of CO2 (Carbon dioxide)
How can the respiratory system put oxygen into the blood and carbon dioxide out of the blood?
Oxygen and carbon dioxide are both gases, which makes them easier to pass through the cell. In addition, the site of trading the respiratory gases occur at alveoli, which has capillaries attached to it. The membranes in these regions are each one cell thick, which enables the respiratory gases to pass through easier. When the blood reaches the lungs, simple diffusions then take the carbon dioxide out of the cell and oxygenates the blood.
