cardiac output can be determined by the following formula
The lungs do not normally collapse during expiration because they are held open by the negative pressure in the pleural space, created by the pulling force of the diaphragm and intercostal muscles. This negative pressure helps maintain the alveoli's shape and prevents them from collapsing completely. Additionally, the presence of surfactant in the alveoli helps reduce surface tension and keeps the alveoli inflated.
Rings of cartilage.
Their rotation.
It prevents you from collapsing like a blob of jello.
The pressure of the fusing gasses
Rings of Cartilage prevents the windpipe from collapsing.cartilage ringsIt is constructed of inflexible cartilage that always maintains it's shape.
This stops air from entering the chest cavity, and prevents collapsing the lung.
The pressure within a protostar counters gravity and prevents the star from collapsing further.

The trachea is bolstered by cartilage tissue, which prevents it from collapsing.
It is a rigid frame that prevents the car from collapsing and crushing car occupants in a roll-over crash
