Homework Answers
1.- e) C and D. Branching always increases surface area, and surface are needs to be increased to more efficiently undergo the gas exchange.
2.- b) The renal medulla. This is because this tissue is closely related to water reabsorbption to concentrate the urine, and high salinity supports this water movement in the correct direction.

NAME SID__ 31. Which of the following is a correct statement when comparing Open Circulatory Systems and Closed Circulatory Systems? a. Open Circulatory Systems generally require MORE energy to operate, since it is less efficient to circulate the entire amount of interstitial fluid in the body cavity. 8. Arthropods and Insects generally use a Closed Circulatory System, while vertebrates generally use an Open Circulatory System Both systems utilize some form of the following three components: (1) circulatory fluid, (2) vessels...

It is 4 hours later, and Karena checks Mr. Ross's respiratory system at bedside with his vital signs. Her unlicensed assistive person reported an axillary temperature of 100.3' F, respiratory rate of 29 breaths per minute and labored, blood pressure of 150/82 mm Hg, and pulse of 104 beats per minute and a pulse ox reading of 89% on O, per nasal cannula at 3 L.

One of the major transitions that we see tied to the movement of the continents, climatic changes, and a series of evolutionary events is the appearance of the first terrestrial vertebrates. Which of these correctly matches a challenge terrestrial vertebrates faced with the solution? Oxygen availability is lower in the terrestrial realm and the evolution of lungs increases surface area to overcome this. Temperature variation decreases and so endothermy evolves as a result, Gravity has a much larger impact and...

answer this question
BLOOD AND FLUID QUESTION 1 (0A patient's blood pressure taken at the arm is 120 mmHg systolic and 70 mmHg diastolic. What would you expect the blood pressure (systolic and diastolic pressures) to be at the top of the head given that this point is 40 cm above the measurement point? Remember blood pressure is a gauge pressure and that 1 kPa = 7.5 mmHg. (The density of blood is about 1060 kg/m.) Choose one: a. 89...
