- Which component of blood is likely to transport most of the oxygenin an icefish?SOURCE: Gills are the main site of gas exchange in almost all fishes. The gills consist of bony or cartilaginously stiffened arches that anchor pairs of gill filaments. In sharks, the pairs of gill filaments are separated by a fleshy septum. The numerous, minute lamellae that protrude from both sides of each filament are the primary sites of gas exchange; however, not all the blood flow in the gills is directed to the lamellae. "Nonrespiratory basal blood channels or venolymphatic simuses may carry a significant fraction of the gall blood found that resting rainbow trout perfused approximately 58% of their lamellae with blood. Trout in hypoxic (low dissolved oxygen) water or injected with epinepherine (eg. simulating stress or excitement) perfused more than 70% of their lamellae. Conversely, injections of acetylcholine decreased perfused lamellae to approximately 43%. These results indicate that rainbow trout can increase the number of lamellae that are used in respiration as the…Name structures P and Q that help humans and fish in gaseous exchange.
- 1) Electric eels are dependent on air breathing. They take up oxygen from the air that they gulp into their mouths and then blow back out. In what way are their mouths similar to gills? A) They both bring oxygen against its concentration gradient from the lower levels in the water or air to the higher levels in the blood. B) They both have large numbers of capillary beds very close to the skin. C) They both have large numbers of microvilli in their respiratory membrane to provide ATP for active transport of oxygen. D) ALL of these are correct. 2) Which of these accurately describes the buccopharyngeal pumping mechanism teleosts use to breathe? A) The volume of oral cavity is rapidly expanded with the mouth closed and the operculum open. B) The volume of the oral cavity is rapidly compressed with the mouth closed and the operculum open. C) Water from the surroundings is sucked into the gills during inspiration and blown back out during expiration. D) ALL of these are correct.what are 2 factors that contribute to the efficiency of gas exchange in fish gills and why are they the most efficient respiratory organ?1) A diver decides to take a balloon with him on a scuba diving excursion to a depth of 10m. The size (volume) of the balloon would _____. A) remain the same throughout the dive B) decrease on the way down and return to its original size on the way back up C) increase on the way down and shrink back to its original size on the way back up 2) How does the size of the air bladder compare between freshwater and salt water fish? A) freshwater fish have larger air bladders because they need to be less dense B) freshwater fish have smaller air bladders because they need to be less dense C) saltwater fish have larger air bladders because they need to be less dense D) freshwater and salt water fish have the same size air bladders because the air bladders play no role in osmoregulation or maintaining salt balance 2) Physoclistous fish fill their air bladders by _____.

Using Fick's law, identify the MAIN factor that is different between these two environments? a) Everything is different in water b) Barrier thickness c) Diffusion coefficient d) Diffusion rate 2. Gills are used by most aquatic invertebrates for gas exchange. What are some of the characteristics they have that make them and ideal gas exchange organ? Select all that apply. a) They are highly folded (increasing surface area) b) They are never used in hypoxic environments (increasing concentration gradient) c) They are only possessed by small organisms (decreasing length) d) They are thin-walled (decreasing barrier thickness).How are diving animals able to remain submerged for extended periods of time without suffering the effects of oxygen deprivation?Define the term “exchange surface” and list four common features of gas-exchange organs in animals.
