College Circulatory and Immune Systems
Would you expect the RBCs of a blue whale (Balaenoptera musculus) to look more like the typical mammalian RBC, or would you expect differences like those seen in the even-toed ungulates (camels etc.)? Why?
  1. Typical - There's no particular reason a blue whale would look different from the typical mammal
  2. Different - They should have RBCs with nuclei and organelles like fish RBCs, since they are also aquatic and breathe water.
  3. Different - They should have much larger RBCs, since RBC size scales with body size.
  4. Different - They might look more like an ungulate's RBCs since they are closely related species (Super Order: Cetartiodactyl).
College Circulatory and Immune Systems
What are the two phagocytic white blood cells of the innate immune system?
  1. neutrophils and monocytes
  2. B-lymphocytes and eosinophils
  3. eosinophils and monocytes
  4. monocytes and B-lymphocytes
College Circulatory and Immune Systems
Which event occurs first during atrial and ventricular diastole in the human heart?
  1. Blood flows into the relaxed atria while the ventricles contract.
  2. The atria and ventricles are relaxed, and blood flows into the atria all four chambers.
  3. The atria contract while blood flows into the relaxed ventricles.
  4. The atria and ventricles contract simultaneously.

College Anatomy and Physiology
The "all-or-none" law refers to the observation that an action potential
  1. will diminish to near zero when transmitted down a long axon.
  2. is conducted more rapidly down the axon as it reaches the axon terminal.
  3. is produced whenever the membrane potential reaches threshold.
  4. fires at the same rate regardless of the inputs to the neuron.
  5. travels only in one direction.
