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. Hand copy onto heading 15 and return this paper to the folder.
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. Arteries & Veins Arteries are thick and have 3 layers
In this photo, you can compare the wall of an artery with the wall of a vein.
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

27. On Assignment 34a, put the following in order
On Assignment 34a, put the following in order. Beginning and ending in the Right Atrium. (Just use the letters.)

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.

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 video Class opener:
Using your book, find the 4 components of blood.
What percentage of your blood is plasma? Cells?

33. Hand copy onto heading 15 and return this paper to the folder.
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

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.

38. blood typing video

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

- Blood and Lymph
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?
O negative or B negative blood; 9%

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.
