How does gas exchange take place?
Gas exchange takes place at a respiratory surface-a boundary between the external environment and the interior of the organism. For unicellular organisms the respiratory surface is governed by Fick's law, which determines that respiratory surfaces must have:a large surface areaa thin permeable surfacea moist exchange surface.
What is an abnormal passage from an internal organ to the body surface or between two internal organs is called?
An abnormal passage from an internal organ to the body surface or between two internal organs is called a fistula.
What covers the most exposed surface of the eye?
retina
Differentiate between interoceptors and exteroceptors relative to location and stimulus source?
interoceptor: responds to stimuli arising within the body exteroceptor: reacts to stimuli in external environment, and typically they are found close to the body surface.
Is gas exchange the same thing a respiration?
inhalation and exhalation takes place in respiration.Gas exchange takes place at a respiratory surface-a boundary between the external environment and the interior of the organism.therefore they both are same things.
What is free surface?
An epithelium always has on surface where the cells are exposed either to the external environment or to an internal passageway or cavity; this surface is called the free surface of the epithelium.

What is the difference between a external parasite and a internal parasite?
An internal parasite feeds with his entire body inside the surface (epithelium, for animals) of the host, while an external parasite feeds with part of, or whole body standing outside the host's surface.

Why the epithelium is much better suited for the body's external surface than mucosa?
Mucus epithelium is very delicate. It can not protect your body from the rough external environment. You need the tough stratified squamous epithelium to protect you from the rough external environment.
