The alveolar sac, also called an alveolus, is lined by cells called type I pneumocytes.

The typical cell making up the alveolar wall is the type I pneumocyte. These cells are thin and delicate, allowing for efficient gas exchange between the alveoli and the blood vessels. Type II pneumocytes are also present in the alveolar wall and play a role in producing surfactant to reduce surface tension and prevent alveolar collapse.
The most common cell making up the alveolar wall is the alveolar type I cell. The result of inspiration is increased alveolar volume causes decreased alveolar pressure.
Thin but strong layers of elastic tissue, with a layer of flattened epithelium, which is one of the four primary body tissues.
Typical plant cells have cell walls, chloroplasts, and large central vacuoles, which are structures that are not typically found in animal cells. These features help plants to support their structure, perform photosynthesis, and store nutrients and waste products.
A typical plant cell has a cell wall, chloroplasts for photosynthesis, and a large central vacuole, while a typical animal cell does not have a cell wall, chloroplasts, or a large central vacuole. Additionally, plant cells have plasmodesmata for communication between cells, while animal cells have gap junctions.
The three types of alveolar cells are type I pneumocytes, type II pneumocytes, and alveolar macrophages. Type I pneumocytes are involved in gas exchange, type II pneumocytes produce surfactant to reduce surface tension in alveoli, and alveolar macrophages help to remove debris and pathogens.
The cell wall is the outer supportive structure of a plant cell. It provides rigidity and support to the cell, helping the plant maintain its shape and structure. The cell wall is made up of cellulose, a complex carbohydrate that gives strength to the cell.
No, a typical plant cell is generally larger than a typical animal cell. Plant cells are usually between 10 to 100 micrometers in size, while animal cells are typically between 10 to 30 micrometers. This size difference is due to the presence of a rigid cell wall in plant cells that provides structural support and allows them to grow larger.
