👉 The term "hypotonicity" refers to a state or condition in which a substance is too dense (i.e., heavier) than its surroundings. In other words, when an object is more dense than its surroundings, it is said to be "hypotonic." This can occur due to factors such as increased water content in the body's fluid compartments like blood and cerebrospinal fluid, or by a decrease in the concentration of solutes in the surrounding environment.
