Describe the events of a cardiac cycle based upon contracting and relaxation phases.

Describe the activity of each chamber during cardiac systole and cardiac diastole. Be able to relate the electrical activity of the heart (depolarization, repolarization) to the corresponding electrical activity depicted on a typical ECG/EKG tracing. Label and define the waves.

Trace the depolarization pathway through the intrinsic conduction system components. Compare and contrast cardiac and skeletal muscle contraction.

Indicate whether each statement is true or false:

1. The intestinal mucosa produces most of the secretions that enter the small intestine, but the secretions of the spleen and the pancreas also enter the small intestine and play essential roles in digestion.   True  False
2. The mucus produced by the intestinal and duodenal glands and the goblet cells protects the wall of the intestine from the effects of the acidic chyme and from digestive enzymes.   True  False
3. Small molecules, which are breakdown products of digestion, are absorbed through the microvilli and enter the circulatory or lymphatic system.   True  False
4. Mixing, propulsion, and mass peristalsis are the primary mechanical functions of the small intestine. True False

For the following two questions, please provide a response of at least one paragraph (and you can certainly write more); question 1b, though technically part of question one, should rate two or three sentences separate from the response for 1a.While there are ‘correct’ answers to these two problems, the emphasis of this assignment is how well you can defend and support your response from the resources available to you.

  1. a) How are the glomeruli of kidney nephrons supplied with oxygen and nutrients? Support and defend your response. (It’s not the afferent arteriole.)

  2. b) Explain why the afferent arteriole is not the answer to part a.

  3. A particular substance can only be removed from the body via the urinary system. However, it is stipulated that there are no anatomical structures or physiological mechanisms within the nephron or its surrounding blood vessels capable of actively transporting the specified substance. Based on that fact, what is the maximum percent of the substance that can be removed from the blood per pass through the kidneys? Support and explain your response from the resources available to you.
