Epithelial tissues.
An exchange surface is in direct contact with the external environment in the respiratory and digestive systems. In the respiratory system, the alveoli in the lungs act as exchange surfaces for oxygen and carbon dioxide. In the digestive system, the lining of the small intestine serves as an exchange surface for the absorption of nutrients.
The capillaries have direct contact with cells in the body. They are tiny blood vessels where the exchange of oxygen, nutrients, and waste products occurs between the blood and the surrounding tissue cells.
External forces can generally be classified into two categories: contact forces, which act through direct physical contact between objects (such as friction or tension), and non-contact forces, which act over a distance without physical contact (such as gravity or electromagnetic forces). Both types of forces can influence the motion or interactions of objects.
Contiguous tissue refers to tissues that are physically connected or adjacent to one another without an intervening gap. This term is commonly used in medical contexts to describe tissues in the body that are in direct contact with each other.
Probably because you can visualize the same from out side. You can list the same in internal body cavity and you wont be wrong. Mostly because the mouth and the anus both lead to the external environment.
distinguish between direct& indirect environment
An exchange surface is in direct contact with the external environment in the respiratory and digestive systems. In the respiratory system, the alveoli in the lungs act as exchange surfaces for oxygen and carbon dioxide. In the digestive system, the lining of the small intestine serves as an exchange surface for the absorption of nutrients.
The are six uncontrollable direct forces of the external environment. The six forces are competition, government policies, natural forces, technological changes, demographic changes, and social/cultural forces.

because their body have a direct contact with the environment
The capillaries have direct contact with cells in the body. They are tiny blood vessels where the exchange of oxygen, nutrients, and waste products occurs between the blood and the surrounding tissue cells.
The direct external environment for an internet cafe includes factors like competition from other cafes, customer preferences, technology trends, and regulatory requirements. The indirect external environment encompasses broader influences such as economic conditions, cultural shifts, social trends, and technological advancements that might impact the industry as a whole. Both of these environments can significantly affect the success and operations of an internet cafe.
Most of its cells are in direct contact with a watery environment

Yes, applied force is a type of contact force. Contact forces are forces that result from physical contact between two objects, where one object applies a force on the other through direct contact. Applied force is a type of contact force where an external force is applied to an object by another object through direct physical contact.
External forces can generally be classified into two categories: contact forces, which act through direct physical contact between objects (such as friction or tension), and non-contact forces, which act over a distance without physical contact (such as gravity or electromagnetic forces). Both types of forces can influence the motion or interactions of objects.
