14 Questions
What happens during the inhalation process?
Oxygen is inhaled from the atmosphere
What is the main function of Hb?
To deliver oxygen and carbon dioxide
What increases inside the Alveoli after the inhalation process?
Partial Pressure of oxygen (PO2)
What happens if we don't inhale oxygen?
The Alveoli collapse
What is the main function of Hb?
Delivering oxygen and carbon dioxide
What happens when the partial pressure of oxygen (PO2) increases inside the Alveoli?
The level of oxygen (O2) is increased
What happens if the alveoli do not receive oxygen (O2)?
The alveoli collapse, leading to lung collapse
Where are red blood cells (RBC) found inside the lung?
Inside the capillaries surrounding the alveoli
What is the structure that surrounds the alveoli and is surrounded by capillaries?
Alveoli
What happens to the partial pressure of oxygen (PO2) inside the alveoli after inhalation?
It increases
Why do we have millions of alveoli in the lung instead of one large alveoli?
To maximize the surface area for oxygen exchange
What is the main consequence of an increase in partial pressure of oxygen (PO2) inside the alveoli on the partial pressure of oxygen inside the red blood cells (RBCs)?
PO2 inside RBCs decreases
How does hemoglobin (Hb) change in the presence of oxygen (O2) inside the red blood cells (RBCs)?
Hemoglobin changes to oxyhemoglobin (HbO2)
What is one of the most important criteria for the separation of oxyhemoglobin (HbO2)?
pH level
This quiz tests your knowledge of the respiratory system and the process of gas exchange. It covers topics such as inhalation, alveoli structure, capillaries, and the transport of oxygen and CO2 by hemoglobin.
