Humans have two eyes which allows us to. Properly working healthy eyes are able to perform the following functions. It is one of the important human eye facts that they help us view our surroundings. Our eyes enable us to see colors. Certain organisms, such as dogs, cannot see colors and, so, their world is black and white.
Eyes help us see near as well as distant objects. The sense organs are eyes, otocysts (organs of balance) and rhinophores or osphradia (olfactory organs). In addition to these organs there are special sensory tracts in various regions of the body which have a less defined and less complex structure.
The eyes are found upon or. Vestigiality is the retention during the process of evolution of genetically determined structures or attributes that have lost some or all of their ancestral function in a given species. Assessment of the vestigiality must generally rely on comparison with homologous features in related species.
The emergence of vestigiality occurs by normal evolutionary processes, typically by loss of. Continued. Three organs play a pivotal role in helping the stomach and small intestine digest food: Pancreas. Among other functions, the oblong pancreas secretes enzymes into the small intestine.

It is seen by both eyes (called binocular vision). An object is seen from slightly different angles by each eye, so the information the brain receives from each eye is different, although it overlaps.
The brain integrates the information to produce a complete picture. This process is the basis of stereo vision or depth perception. GHS Classification Criteria in A Single Page.
