13. 3/19 • Review 3 Functions of the Circulatory System • Review Heart Structure • 3 types of Blood Vessels • Blood Vessel Flipbook • #Closure : 3 things you learned today 2 things you clarified 1 question you still have

14. Review Continued • List and describe the three functions of the cardiovascular system. • Define: • Valve • Pacemaker • Septum

15. Answers • Functions • Deliver needed materials, such as oxygen and glucose, to the cells of the body. • Remove waste products, such as carbon dioxide, from the cells. • Fighting diseases by transporting white blood cells throughout the body.

16. Answers • Define: • Valve – a Flap of tissue that separates the atria and ventricles, and prevents blood from flowing backward • Pacemaker - a group of nerve cells in the right atrium that signal the heart muscle to contract • Septum – a wall of tissue that separates the right side of the heart from the left side of the heart

17. The Heart • The heart is a hollow, muscular organ that pumps blood throughout the body. • It is located behind the sternum, inside the rib cage • It is made of cardiac muscle, which can contract over and over without getting tired

18. Heart Structure • The right side of the heart is completely separated from the left side by a wall of tissue called the septum • Each side has two compartments, or chambers • Atrium (atria = plural) – the upper chamber that receives blood coming into the heart • Ventricle – the lower chamber that pumps blood out of the heart • Flaps of tissue called valves, separate the atria and ventricles, and prevent blood from flowing backward. • In the right atrium, there is a group of nerve cells known as the pacemaker, that signal the heart muscle to contract

19. Wednesday’s Quiz • List and describe the three functions of the cardiovascular system • Matching definitions – valve, septum, pacemaker, atrium, ventricle • Label the three types of blood vessels • Compare and Contrast the structures of the three blood vessels. • Explain how the structures of each blood vessel are related to their functions.

20. Blood Vessels – 3 Types • Arteries – carry blood away from the heart • Capillaries – tiny vessels (only one cell thick) where materials are exchanged between the blood and the body’s cells • Diffusion – the process by which molecules move from an area of high concentration to an area of low concentration • Veins – carry blood back to the heart

21. Blood Vessels • The walls of arteries and veins have three layers. The walls of capillaries are only one cell thick.

22. Getting back… • When blood reaches the veins, the heart has very little effect on it. • Contractions of skeletal muscles next to the veins, squeeze the blood back towards your heart. • Also, large veins in the body have valves to prevent the blood from flowing backwards.

23. In this photo, you can compare the wall of an artery with the wall of a vein. Arteries are thick and have 3 layers Arteries & Veins Veins also have 3 layers but they are much thinner.

24. Blood Pressure • Blood pressure - the force blood exerts against the walls of blood vessels • Caused by the contracting of the ventricles • Decreases as it moves away from the heart.

25. Path of Blood Flow: • On the back of the Heart Structure and Blood Flow Handout, using your handout and page 536 in your book, list the path blood takes through the heart/body/lungs (in order). • Begin and end at the right atrium.

26. Path of Blood Flow • Right Atrium • Right Ventricle • Pulmonary Arteries • Lungs • Pulmonary Veins • Left Atrium • Left Ventricle • Aorta • Body • Veins from body • Right Atrium

27. On Assignment 34a, put the following in order. Beginning and ending in the Right Atrium. (Just use the letters.) A. Lungs B. Left Atrium C. Right Atrium D. Veins from body E. Pulmonary Veins F. Body G. Pulmonary Arteries H. Left Ventricle I. Aorta J. Right Ventricle K. Right Atrium

28. Answers • C, K • J • G • A • E • B • H • I • F • D • C, K

29. Two Loops • Loop 1 - blood travels from the heart to the lungs and then back to the heart. • Loop 2 - blood is pumped from the heart throughout the body and then returns to the heart.

30. 4/2 • Review the Path of Blood #34a 5 min • Class Opener #34b • Blood Notes • Heart Function and Blood Vessels Quiz Make-up Tomorrow Learning Goal: Students will understand that blood is a specialized fluid that has four main components. Each component has a unique function. Students will apply their understanding of components of blood to discuss how this impacts receiving blood from a donor.

31. Heading 34: Components of Blood videoClass opener: • Using your book, find the 4 components of blood. • What percentage of your blood is plasma? Cells?

33. Blood • Blood consists of liquid plasma and three kinds of cells—red blood cells, white blood cells, and platelets. • Plasma – the liquid portion of blood – 90% water & 10% glucose/fat /vitamins/minerals • Red Blood Cells – carry oxygen from lungs to body and carbon dioxide away from body, back to lungs • White Blood Cells – find and destroy disease causing organisms • Platelets – fragments of red blood cells that help form blood clots

34. Blood Red Blood Cell White Blood Cell Platelet

35. 4/3 • Review the heart anatomy • Class Opener • Blood Typing Notes (#34 continued). • Finish Blood Worksheet side 1 only • Heart Function and Blood Vessels Quiz Make-up Today Learning Goal: Students will understand that blood is a specialized fluid that has four main components. Each component has a unique function. Students will apply their understanding of components of blood to discuss how this impacts receiving blood from a donor.

36. Blood Types • Blood types are determined by proteins known as marker molecules that are on RBCs. • Blood type A has the A marker • Blood type B has the B marker • AB has both A & B markers • O has no markers

37. Plasma contains clumping proteins that don’t recognize RBCs with different markers. • If you have blood type A and get a transfusion of type B blood, your plasma will clump the B blood together. • The markers on your blood determine the type(s) of blood you can safely receive.

39. Rh Factor • Rh factor is also determined by a marker on the RBCs. • Rh+ means you have the marker • Rh- means you don’t have the marker • Rh- blood will develop Rh clumping factor if it receives Rh+ blood

40. - Blood and Lymph • The percentage of each blood type found in the United States population • Reading Graphs: • What does each edge of the graph represent?

41. - Blood and Lymph • AB (4%), B (11%), A (40%), O (45%) • Interpreting Data: • Rank the four major blood types—A, B, AB, and O—from least common to most common. What is the percentage of each type?

42. - Blood and Lymph • 84%; 16% • Calculating: • According to the graph, what percentage of the population is Rh positive? What percentage is Rh negative?

43. - Blood and Lymph • O negative or B negative blood; 9% • Predicting: • What type of blood can someone who is B negative (blood type B and Rh negative) receive? What percentage of the population does that represent?

44. Lymphatic System • Sometimes the fluid leaks out of the blood vessels as it travels throughout the body. • The lymphatic system is a network of vein-like vessels that returns the liquid to the bloodstream. • Lymph – fluid that consists of water, glucose, and WBC • Lymph nodes – filter lymph, trapping bacteria and other disease causing organisms

45. Prime Time: • Using your textbook, read pages 548 – 550. Start at “Blood Types” and stop at “The Lymphatic System.” • On a clean sheet of paper with heading #16, answer questions 1-4 on the top pf page 550.
