Front

What is Internal Respiration?

Internal Respiration is the process of gas exchange between the blood and the body's tissues, where oxygen is delivered to cells and carbon dioxide is removed.

Front

What is the Pleural Space?

Back

The Pleural Space is the thin fluid-filled space between the two pleurae (visceral and parietal) that allows for smooth movement of the lungs during breathing.

Front

What is the Visceral Pleura?

Back

The Visceral Pleura is the inner membrane that directly covers the lungs.

Front

What is External Respiration?

Front

What are C-shaped cartilage rings?

Back

C-shaped cartilage rings are structures that provide support to the trachea, preventing it from collapsing during breathing.

Front

What is Surfactant?

Back

Surfactant is a substance produced in the lungs that reduces surface tension in the alveoli, preventing their collapse and aiding in lung expansion.
