HUMAN ANATOMY AND PHYSIOLOGY (BBTC 1063) Tutorial 9: Chapter 8-9 1. List major components of the heart. 2. State FOUR (4) major functions of the heart. 3. Name TWO (2) valve that prevent backflow in the heart. 4. Describe the flow of blood through the cardiac veins. 5. Explain the conducting system of the heart 6. Explain why Sa node is the pacemaker of the heart 7. How does the polarization pacemaker cells differ from the depolarization of other cardiac muscle cells? 8. What does ECG measure? 9. List the waves produces by an ECG. Draw the diagram of ECG graph. 10. Define systolic and diastolic. 11. Differentiate between intrinsic and extrinsic regulation of the heart. 12. Discuss the role of mean arterial pressure in causing blood flow 13. State the function of hepatic portal system. 14. What part of the brain regulates the heart? Describe the autonomic nerve supply to the heart. 15. What effect do parasympathetic have on the heart rate, force of contraction and stroke volume? 16. Name TWO (2) hormones that affect the heart. 17. Define plasma. State the functions of albumin, globulins and fibrinogen in plasma. 18. Name the general types of formed elements in the blood. 19. Discuss how the blood helps to maintain body homeostasis. 20. What is hematopoiesis? 21. How does the RBC acts to exchange gases and move through blood vessels? 22. Describe the basic parts of hemoglobin. 23. Discuss about erythropoiesis. 24. List TWO (2) major functions of WBC 25. Describe the major roles of platelets in preventing blood loss? 26. Describe the process of platelet plug formation 27. Explain the physiology of capillary exchange.Explanation / Answer
1ans-4 chambers: the right atrium, left atrium, right ventricle, and left ventricle,Muscular walls, called septa or septum,volves of the heat and conduction system.
2 ans-pumps nutrients and waste throughout the body.
Pumps blood that carries gases i.e CO2 and O2.
Pumps blood that Carries hormones (endocrine).
Maintain homeostasis.
3 ans-Tricuspid volve, bicuspid or mitral volves.
4 ans-In the right side of the heart Blood enters the heart through two large veins, the inferior and superior vena cava, emptying deoxygenated blood from the body into the right atrium and the Left side of the heart the pulmonary veins empty oxygenated blood from the lungs into the left atrium.
5 ans-The cardiac conduction system comprises of the:
Sinoatrial (SA) node
Atrioventricular (AV) node
Bundle of His
Bundle branches
Purkinje fibres
6-ans-SA node is a mass of cell in the right atrial wall and main generator of electrical impulses called pacemaker because it's originate the impulses at first, maintain the normal cardiac rhythm and conduct electrical impulses.
