WebbThe rectal gland is the principal salt-secreting organ in elasmobranchs, yet its functional response to normal physiological variation (e.g., due to feeding, stress) has only recently been examined. To complement studies on acid-base, digestive, and osmoregulatory physiology in response to Webb3) Cl- diffuses down its concentration gradient into the lumen of the rectal gland. 4) Na+ moves down their electrochemical gradient into the lumen of the rectal gland. Fish that change from fresh to saltwater Use a Na+/Cl-/K+ cotransporter to help move ions either in or out of the gills, depending on the water environment

WebbThese animals that secrete urea are called ureotelic animals. TMAO stabilizes proteins in the presence of high urea levels, preventing the disruption of peptide bonds that would occur in other animals exposed to similar levels of urea. Sharks are cartilaginous fish with a rectal gland to secrete salt and assist in osmoregulation. WebbThe morphology of the rectal gland was examined in spiny dogfish ( Squalus acanthias L, 1758) sharks fasted (1 week) or 6 and 20 h postfeeding. The morphology of the fasted gland showed a pattern reflecting a dormant physiology, with thick gland capsule, thick stratified epithelium, and secretory parenchyma with tubules of small diameter and lumen. how can i stop my streaming from buffering

WebbThe Shark Inside. The inside of the shark is designed for maximum efficiency, just like its outside. Sharks have large J-shaped stomachs that can expand considerably. When prey is captured, it is usually swallowed whole or in large pieces. The stomach produces an acid that is strong enough to dissolve metal. Large bones and other indigestible ...
