Mouth esophagus, rumen, reticulum, mouth, omasum, abomasum b. Mouth, esophagus, reticulum, mouth, rumen, abomasum, omasum c. Mouth, esophagus, abomasum, omasum, mouth, reticulum, rumen d. Mouth, esophagus, rumen, reticulum, omasum, abomasum, mouth Blood moves through the heart in the following order (there may be steps missing, you should still be able to answer this): a. R atrium, L atrium, pulmonary artery, pulmonary veins, L ventricle, R ventricle, aorta b. R atrium, R ventricle, pulmonary veins, pulmonary artery, L atrium, L ventricle, aorta c. R atrium, R ventricle, pulmonary artery, pulmonary veins, L atrium, L ventricle, aorta d. Aorta, R atrium, R ventricle, pulmonary artery, pulmonary veins, L atrium, L ventricle A decrease in which of the following would decrease the rate of gas exchange a. Surface area. b. Pressure distance between the two sides c. Distance over which diffusion occurs d. Both b and c e. Both a and b

Explanation / Answer

Answer:

1) Organisms that are ruminants have a very different method of processing food prior to its arrival in the intestines. Which of the following is the correct path of the food?

a) Mouth, esophagus, rumen, reticulum, mouth, omasum, abomasum -  Correct Order

b) Mouth, esophagus, reticulum, mouth, rumen, abomasum, omasum

c) Mouth, esophagus, abomasum, omasum, mouth, reticulum, rumen

d) Mouth, esophagus, rumen, reticulum, omasum, abomasum, mouth

2) Blood moves through the heart in the following order:

a) R atrium, L atrium, pulmonary artery, pulmonary veins, L ventricles, R ventricles, aorta

b) R atrium, R ventricle, pulmonary veins, pulmonary artery, L atrium, L ventricle, aorta

c) R atrium, R ventricle, pulmonary artery, pulmonary veins, L atrium, aorta - Correct Order [After L atrium it will go to Left Ventricle (missing step) and then to aorta.]

d) Aorta, R atrium, R ventricle, pulmonary artery, pulmonary veins, L atrium, L ventricle

3) A decrease in which of the following would decrease the rate of gas exchange.

a) Surface area

b) Pressure distance between the two sides

c) Distance over which diffusion occurs

d) Both b and c

e) Both a and b - Correct Answer (Explanation: Decrease in surface area of membranes significantly impedes the exchange of gas, decrease in pressure difference decrease the rate of exchange of gas)

Please note: Instead of pressure distance between the two sides - *term could be be "pressure difference between the two sides")
