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.
The pupil acts as an entry point for light to enter your eye. Surrounding muscles in the iris, called the pupillae, adjust the pupilâs size automatically depending on light conditions. In light conditions, your pupil will probably be around 3mm in diameter. In total darkness, this diameter can extend to over 6mm.
