The shark kidney excretes urea that is needed for the shark to have in its system so the shark does not become dehydrated from living in seawater. [14] Sharks hearts have two chambers. The shark heart's main importance is providing oxygenated blood to the entire body while filtering out the deoxygenated blood. [15]
The spiracle is often located towards the top of the animal allowing breathing even while the animal is mostly buried under sediments. [5] As sharks adapted a faster moving lifestyle some became obligate ram ventilators , breathing exclusively by forcing water through their gills by swimming; among these are requiem sharks and hammerhead sharks ...
The respiratory system (also respiratory apparatus, ventilatory system) is a biological system consisting of specific organs and structures used for gas exchange in animals and plants. The anatomy and physiology that make this happen varies greatly, depending on the size of the organism, the environment in which it lives and its evolutionary ...
Also present on the lower jaw are two fleshy barbels, chemosensory organs which help the nurse sharks find prey hidden in the sediments. Behind each eye is a very small, circular opening called a spiracle, part of the shark's respiratory system. The serrated teeth are fan-shaped and independent; like other sharks, the teeth are continually ...
A shark, also called a "selachimorph", can be described as all of the following: Animal – multicellular, eukaryotic organism of the kingdom Animalia or Metazoa. An animal's body plan eventually becomes fixed as it develops, although some types of animal undergo a process of metamorphosis later on in their life.

In birds, some temperature control occurs in the respiratory system. [16] Water vapor heats cool air during inhalation in the trachea, and increases its humidity. [16] The resulting evaporative water loss varies greatly and depends on several factors including air sac pressure and the subsequent rate of air flow through the trachea.
