Question

Which of the following sequences correctly lists structures in order of decreasing oxygen content (from to lowest)? tissues. capillaries. blood. gill. water water, blood, gill. capillaries. tissues blood, gill, capillaries, tissues, water gill, blood. tissues, capillaries, water water, gill, blood, capillaries, tissues Find volume refers in the volume of blood in the aorta when the heart is relaxed. heart immediately prior to contraction. aorta during filling. diastome, heart immediately after contraction. Filtration of fluid from the blood to the extracellular space occurs at which portion of a capillary bed arterial end venous end all along the capillary bed What is the P50 for hemoglobin represented by curve C to the right? 35 mmHg 50 mmHg 18 mmHg 255 mmHg cannot be determined from the graphed data Which is the most accurate description of energy expenditure in a poikilotherm? As temperature rises, metabolic rate rises, and oxygen consumption rises As temperature rises, metabolic rate rises, and oxygen consumption falls As temperature rises, metabolic rate falls, and oxygen consumption rises As temperature rises. metabolic rate falls and oxygen consumption falls Which of the following terms is a correct expression for average daily metabolic rate? (which correct units?) ml O2/g/km ml O2/g/hr ml O2/kg J/m/kg km/hr/g Referring to the graph here, the resting metabolic rate of the white mouse is: between 34 ml O2/g/h (6-3.2 ml O2/g/h)/(1 km/h) not specified by these data dependent on running speed greatest when the animal is thermoregulating

Explanation / Answer

24. Structures in order of decreasing oxygen content from highest to lowest is water, gill, blood, capillaries, tissues.

Correct sequence is E.

25. End diastolic volume of blood is preload of blood before systole that is volume of blood in left/right ventricle immediately prior to contraction of heart for systolic motion.

Correct answer is b.

26. Filtration of blood in capillaries take place via hydrostatic force (force due to blood flow in capillaries) and oncotic or sterling force( due to plasma proteins). At venous end reabsorption of fluid takes place and at arterial end filteration of blood takes place. In mid of capillaries these forces are nominal and no filteration occurs in mid of capillaries.

So correct answer is a that is arterial end.

27. P50 indicates the partial pressure of gas required to achieve 50% enzyme saturation. It is analogous to Michaelies - Menten constant km .

Here graph is not readable clearly and hence presuming that on Y axis of graph km is gvn which is nearby 35.

28. Most accurate description of energy expenditure in poikilotherms is

Temperature rises leads to increase in their metabolic rate which increases consumption of oxygen.

Hence A is correct.

29. As rate refers to w.r.t. time comparison so correct answer is b that is correct expression for metabolic rate represented by ml O2/g/hr

30. On x axis graph shows running speed of different animals and on Y axis their respective metabolic rate with respect to their running speed.

Here white mouse metabolic rate shown w.r.t. it's running speed is 6-8 ml O2/g /h and we know that metabolic rate in rest is less than running. Hence a is Correct.
