10 Questions
In pneumonia, air passages in the lungs are not obstructed.
False
90% of the lung's capacity is affected by the obstruction in pneumonia.
True
The blood flows to the entire lung and not to a part of it.
False
Pneumonia is a condition where the air passages in the lungs are fully open.
False
The blood flow to the lung is not affected in pneumonia.
False
Pneumonia affects only a small part of the lung's capacity.
False
The lung's capacity is completely unaffected in pneumonia.
False
In pneumonia, the blood flow is normal and unaffected.
False
Pneumonia causes a complete blockage of the air passages in the lungs.
False
Pneumonia is a condition where the blood flow to the lung is normal.
False
Study Notes
Respiratory System
- The respiratory system helps maintain fluid balance in the body and humidifies the air we breathe.
Voice Production
- The respiratory system plays a role in voice production.
Dust Removal
- The respiratory system helps remove dust particles stuck to the moist lining of airways.
Breathing Rate
- We breathe approximately 6 liters of air per minute.
- At rest, men breathe approximately 12 times per minute.
- At rest, women breathe approximately 20 times per minute.
- At rest, infants breathe approximately 60 times per minute.
Air Composition
- The air we inspire is approximately 80% N2 and 20% O2.
Oxygen and CO2 Diffusion
- Oxygen diffuses from the alveolus into the red blood cells.
- CO2 diffuses from the blood into the air in the alveoli.
Ventilation
- Ventilation involves getting air to the alveolar surface.
- Ventilation can be obstructed in conditions like pneumonia, affecting approximately 90% of lung capacity.
Blood Flow
- Blood flows through the pulmonary capillaries surrounding the alveoli, allowing for gas exchange.
This quiz covers the functions of human body systems, including balance of fluids, respiration, and voice production.
