What are pharyngeal slits?
Pharyngeal slits are openings through which water is taken into the pharynx, or throat.
What does pharyngeal pouches mean?
it means slits it means slits
What functioned first does a chordate pharyngeal slits appear to have?
Chordate pharyngeal slits appear to have functioned first as suspension-feeding devices.
What is a pharyngeal gill?
Pharyngeal slits are not gill slits. They are filter-feeding organs in non-vertebrates, and are used to strain matter and food from water.
What organisms have pharyngeal pouches that are in the form of slits?
Fish
What types of embryos have pharyngeal slits?
all chordates
What is the function of pharyngeal slits?
The main function of the pharyngeal slits is to breathe. They are openings that allow breathing underwater using the throat. They are also necessary for some organisms to filter feed.
What do Pharyngeal pouches become in Fish?
gill slits
Do pharyngeal slits disappear before birth in all chordates?
yes or no
Why do fetuses develop pharyngeal slits?
The development of pharyngeal slits in fetuses is believed to be a call back to our evolutionary history. As I'm sure your aware humans and any living vertebrates belong to the phylum Chordate which is part of the Deuterostomes branch of the animal kingdom. You may have heard about the theory of how modern day mammals and so hence man evolved from fish. Well the presence of pharyngeal slits in fetuses is one piece of evidence for this theory. As pharyngeal slits are used in simple organism such as Hemichordates to filter feed in water. Organisms classified as Deuterostomes are done so by the presence of these pharyngeal slits at some stage during their development ( In fish embryos it is the pharyngeal slits which develop into the gills), amongst some other similar developmental patterns. I hope this helps to answer your question.
What are the characteristics of nonvertebrate chordate?
Chordates are the organisms that have a rod like cartilagenous structure called notochord which gives rise to nervous system. These have pharyngeal gill slits. Nonchordates are the organisms that do not have a notochord. These do not have pharyngeal gill slits.
What are the respiratory organs of chordates?
Gills I think, like pharyngeal gill slits ... maybe ....
