BSC 2011 Dr. Presley Hints for Exam 3 Hints for Exam 3 1 HINTS FOR EXAM 3 Exam 3 date is ______________. Check your syllabus or assignment calendar for exact date. Exam 3 covers the second portion of the animal/human physiology section (Chapters 50, 42, 51, 52, 43). Eventually you will be studying these systems in your pig during the laboratory. There is no chart or materials that will be allowed during the testing. You need to pay particular attention to my chapter notes and keep updating your animal chart as it relates to the various systems. You will want to study not only the human system but also maintain a comparative physiology study of the phylogenetic development of these systems. (This is where additional work on your Animal Kingdom chart may help and then pay off especially for study for the final exam). Use the publisher’s website and the WebCT chapter quizzes for study. The following is a study guide to some of the most commonly missed questions. Study each of these. Contact your classmates for their suggestions of answers or study helps for these topics. 1. Circulation . What is a gastrovascular cavity? What are some organisms that possess a gastrovascular cavity? What are the functions of the gastrovascular cavity? What is hemolymph and how does it flow? What organisms have an open circulatory system? Describe the flow in a double circuit closed circulatory system. Give examples of animals with the double circuit system. How many pumps does this double circuit system have? How many capillary beds must the blood go through in a typical double circuit? Explain the advantage observed in animals that have a double circuit system with 3, incomplete 4, and 4 chambered hearts. Which of these are homeotherms? What are the functions of the mammalian cardiovascular system? Follow a drop of blood through the heart naming every chamber and valve it passes from the return from the systemic circulation, through the pulmonary circulation and pumping into the systemic circulation. Where is the hepatic portal system and why is it important? What happens during ventricular diastole? What heart structure initiates the heartbeat? How is this message for contraction spread through the heart? What two systems can have an affect on the heart rate in order to meet homeostatic needs? How do you compute cardiac output? If you have a blood pressure of 120 over 70, what does the bottom number refer to? What does that top number represent? Name the five types of blood vessels. Compare the structure of arteries and veins: thickness of smooth muscle middle layer, thickness of outer connective tissue layer, will vessel collapse when empty, pressure on blood flowing through, presence of valves. What prevents the blood from flowing through the entire capillary bed of inactive tissues? Blood hydrostatic pressure is the main force for filtration at the arterial end of the capillary. What is the principle force for reabsorption at the venous end of the capillary? Describe the three
