We don't have Gil filaments but fish do.
Oh honey, let me set the record straight for you. Teeth are as important to the respiratory system as a bicycle is to a fish. In other words, they have absolutely nothing to do with each other. Teeth are for chewing your food, while the respiratory system is all about breathing in that sweet, sweet oxygen. So, no, teeth are not part of the respiratory system - case closed.
An organ system would be composed of all the other options listed: cells, tissues, and organs. Organ systems are made up of organs, which are made up of different types of tissues, which are in turn composed of cells.
Gills have a large surface area covered by thin, moist membranes that are highly vascularized, allowing for efficient exchange of gases (oxygen and carbon dioxide) between water and a fish's bloodstream. The gill's structure and counter-current flow system in fish enhances the exchange of gases by maintaining a steep concentration gradient across the respiratory membrane, facilitating efficient gas exchange.
The operculum is part of the respiratory system in fish. It is a bony flap that covers and protects the gills, helping with the process of obtaining oxygen from water.
Humans primarily use air as their respiratory medium, extracting oxygen from the air and releasing carbon dioxide. Fish, on the other hand, use water as their respiratory medium, extracting oxygen from the water through their gills.
gills which are their lungs
vascular system of star fish
Lungs for land (or air breathing) animals, Gills for fish, pores for insects.
gills
There are many similarities between fish and humans. Fish and humans have many of the same organs. We both have a digestive system and a reproductive system.
respiratory system of gold fish
a organ systems are shared by both fish and birds because they have the same respiratory system, nervous system and reproductive system.
Internal Gills
why man and fish both supplies a large amount of blood
The spelling of the plural noun is gills (organs that extract dissolved oxygen from the water).
cos day breathe in H2O innit and there trachea is more complex and blood vessels spread out on the gills to create a bigger surface area. :)
amphibians breath with the help of both gills and lungs. example frog. frog in its larval stage is called a tadpole and its respiratory organ is gills. in its later stages of life (adult) its respiratory organs changes into lungs
