how fish seprat oxygen from water in respiration time |
| Answer» Fish are the aquatic vertebrates which respire through structures called as gills. This is called as branchial respiration.\tGills are present on either side of the head and are supplied by rich blood vessels.\tFish obtain oxygen dissolved in water.\tDuring respiration, water enters the body through mouth, passes through gills and comes out of the operculum.\tExchange of gases takes place in the gills of fish supplied by numerous blood vessels.\tThey accept oxygen into the body and expel out carbon dioxide.\xa0 | |
