Humita (from Quechua humint'a) is a Native American dish from pre-Hispanic times, and a traditional food in Argentina, Bolivia, Chile, Ecuador and Peru, although their origin is unclear. In Argentina, Chile, Ecuador and Peru they are known as humitas, in Bolivia as humintas, in Brazil as pamonha, and in Venezuela as hallaquitas. It consists of masa harina and corn, slowly steamed or boiled in a pot of water.
A greater intensity of light causes the pupil to constrict (miosis/myosis; thereby allowing less light in), whereas a lower intensity of light causes the pupil to dilate (mydriasis, expansion; thereby allowing more light in). Thus, the pupillary light reflex regulates the intensity of light entering the eye.
Pupil. The visible black center of the eye is the pupil. The pupil works like the aperture or opening of a camera to regulate the amount of light entering the eye. In bright light, the pupil closes down to limit how much light comes into the eye. In dim light the pupil opens up and becomes visibly larger. This allows the eye to receive more light.
