Study Notes
Lung Structure and Function
- Lungs are situated in the chest cavity, one on the left and one on the right side of the body.
Oxygen Transport
- Oxygen from the lungs is carried by the blood to the tissues through a process called oxygenation.
Pleura Function
- The pleura, a thin membrane covering the lungs, reduces friction between the lungs and chest cavity during breathing.
Lung Shape
- The lungs are cone-shaped organs.
Respiratory Process
- The stage of the respiratory process that involves the distribution of oxygen-rich inspired air with the air already present in the lungs is called ventilation.
