The human respiratory system is designed for efficient gas exchange, allowing for the intake of oxygen and the expulsion of carbon dioxide, which supports high metabolic activity and energy production. In contrast, a fish respiratory system utilizes gills to extract oxygen from water, allowing fish to thrive in aquatic environments where oxygen levels can be lower. Both systems are highly specialized for their respective environments, enabling each organism to maximize oxygen uptake and maintain metabolic functions effectively. This adaptation illustrates the diversity of life and the evolutionary solutions to respiratory challenges in different habitats.
gills
Because a dolphin is a mammal, and not a fish. A dolphin's respiratory system is similar, for the most part, to a human's respiratory system.
Most fish use gills for gas exchange instead of lungs

Humans must first dissolve the gasses in water (in the alveolii of the lungs) before we can extract it, whereas fish only can get the gasses already dissolved. Also - fish have a one-way respiratory system whereas humans have an in and out respiratory system.
respiratory system of gold fish
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.
Internal Gills
gills which are their lungs
suck my dick
yes it does LOL!
