Pneumocyte Type I

Thin, flattened epithelial cells forming the majority of the alveolar surface, specialized for efficient gas exchange.

Key Functions:

• Forms the primary barrier for gas exchange in the alveoli.
• Provides a large surface area for diffusion of oxygen and carbon dioxide.
• Highly permeable to gases.

Interacting Systems & Components:

• Alveoli (forms part of)
• Lung (located in)
• Respiratory System (facilitates gas exchange)
• Epithelial Cell (type of)
