Question
Chapter 36, Problem 7TY
Summary Introduction
Introduction:
The fishes possess a specialized respiratory structure called internal gills. These are covered by a bony plate called an operculum. The space beneath the operculum protects the gills and assist in streamlining the body.

You receive animal care and use committee approval to catch a fish, prop open its
operculum (gill cover), tie a string around its tail, and tow it backwards through the
water for experimental purposes. The fish is then released unharmed. This action
forces water to flow backwards over the gill filaments and in between the gill
lamellae. What effect would this backwards water flow have on respiration?
It would reduce efficiency of gas exchange between water and blood
The only effect would be due to the fish's discomfort from this treatment.
O It would improve efficiency of gas exchange between water and blood
Swim bladders in fish and lungs in terrestrial animals have a common evolutionary origin, but have
evolved to perform different functions. What is the primary function of swim bladders in fish?
They serve as buoyancy control organs.
They filter toxins from the water.
They allow fish to absorb most of their oxygen.
They help in the digestion of food.
If a fish close to the surface swam down to a depth of 10m below the surface it would need to ______ to maintain neutral buoyancy.
let air out of its swim bladder to keep the volume constant
let air out of its swim bladder to reduce the volume constant
put air into its swim bladder to keep the volume constant
put enough air into its swim bladder to double the volume

- Because flight is metabolically demanding, birds have very efficient systems that help to meet these demands. Look at the following list of characteristics and choose those that contribute to the physiological demands of flight. One-way airflow respiration Endothermy Large heart Nucleated red blood cells Slow heart rate Two-cycle lung ventilation Air sacs Separate pulmonary / systemic circulation Air capillariesarrow_forwardFigure 39.7 Which of the following statements about the mammalian respiratory system is false? When we breathe in, air travels from the pharynx to the trachea. The bronchioles branch into bronchi. Alveolar ducts connect to alveolar sacs. Gas exchange between the lung and blood takes place in the alveolus.arrow_forwardWhat causes air to enter human lungs? The contraction of the diaphragm increases the volume of the lungs, decreasing the pressure relative to the air outside the body. Smooth muscle in the trachea guides the flow of air into the lungs. Air diffuses into the lungs due to the decreased O2 content relative to the air outside our body. The cilia in the trachea guide the flow of air into the lungs. The decreased concentration of O2 in the lungs decreases the density of that air and denser air outside the body "sinks" into the lungs.arrow_forward
- Which of the following is NOT an example of where the surface area to volume ratio is increased to improve diffusion: microvilli in the small intestine of a human alveoli in the lungs of a mouse o air sacs in the respiratory system of a bird long intestine in an earth worm lamallae in gills of fisharrow_forwardSOURCE: 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…arrow_forwardPut the following in order by numbering from 1 to 5 - Diaphragm contracts and flattens and ribs elevate - The diaphragm returns to its dome shape resting position - The thoracic cavity increases in volume - Air inters the lungs due to a lower pressure gradient than atmospheric pressure - A subatmospheric pressure is created in the lungsarrow_forward
- a) Gill lice infections result in lowered surface area to volume ratios in fish gill structure. True False Levels of carbon dioxide in the blood will not differ between infected and uninfected fish. Question options: True False The branched nature of capillaries in fish gills increases surface area, and thus the efficiency of exchange into/out of the blood stream lation. Question opti True Falsearrow_forwardWhich of the following statements about oxygen transport is TRUE. Increases in temperature and decreases in pH cause myoglobin to release oxygen to improve delivery to the hemoglobin in muscles. A molecule of myoglobin has higher oxygen binding capacity than a molecule of hemoglobin. Myoglobin has a higher oxygen affinity than does hemoglobin. Fetal hemoglobin has a lower affinity for oxygen than maternal hemoglobin, which makes it better suited to extract oxygen from the maternal circulation.arrow_forwardDiscuss Tidal, residual, minimal air in Gaseous Exchange in Animalsarrow_forward
