Intra-alveolar surface tension is due to the presence of surfactant molecules that reduce surface tension within the alveoli, preventing lung collapse by maintaining alveolar stability during breathing. Surfactant helps to reduce the work of breathing and facilitates gas exchange by preventing alveolar collapse at the end of expiration.
Yes, cilia are present on the apical surface of some cells. They serve various functions, such as moving substances along the cell surface or sensing the environment.

Intra-alveolar surface tension is caused by the presence of fluid lining the alveoli, mainly composed of surfactant molecules. Surfactant helps reduce surface tension by lowering the cohesive forces between water molecules, preventing alveolar collapse during exhalation and allowing for efficient gas exchange in the lungs.

Cilia and flagella are hair-like structures that protrude from the surface of cells and are involved in movement. They can help propel cells or move substances across the cell surface.

Short hairlike projections on a cell surface are called cilia. Cilia are specialized structures that act like tiny antennas, helping cells to sense their surroundings and move substances across the cell surface.

The loss of alveolar surface area is referred to as "alveolar destruction" or "alveolar collapse." This condition can occur in various respiratory diseases, such as emphysema, where the walls of the alveoli are damaged, leading to a reduction in gas exchange efficiency. This loss impairs oxygen uptake and carbon dioxide removal, contributing to respiratory complications.

Short hairlike projections that are used for locomotion are called cilia. Cilia are normally found on unicellular organisms and not multicellular organisms.
Cilia and flagella are hair-like structures found on the surface of some cells. They help with movement and can either propel the cell through its environment (flagella) or move substances along the cell surface (cilia).
