Procedure 1:
•Coloured pencils
•Blank paper Procedure
2: •https://www.youtube.com/watch?v=yE3Y-XR8Ax4‘What’s inside a heart?
Heart Dissection We the Curious’ Procedure 3:
•Internet for research
Procedure 4: •Drug store blood pressure station METHODS This lab is a series of activities that you will be doing. After you have completed the activities, write the results up in a formal lab report.
Procedure 1:1.Draw a simple heart diagram andlabel showing attached blood vessels, chambers,and valves (make sure to add a Figure # and a descriptive title).On your heart diagram, usearrows to show the path of blood as it moves through the heart. Colour the pathways of deoxygenated blood blue,and oxygenated blood pathways red.
2.Write a flow chart listing the direction of blood flow through the heart.
Procedure 2: In this activity you will be watching a video of a heart dissection to help you learn the parts and the direction of blood flow by better understanding the anatomy of the heart. In the discussion part of your lab report include the answers to the following questions:
1.As the narrator describes the path of blood through the heart, he fails to mention the first heart valve, what is the name of this valve and where is it?
2.As he continues with his story he talks about the heart strings; what is another name for these?
What are they used for?

What is the last valve on the path of blood through the heart, which he again fails to talkabout –and where is it?
4.He compares the muscle walls of the right and left ventricle; what is the difference between the right and left and why?
Procedure 3: 1. Research how blood pressure, osmotic pressure, and concentration gradient,contribute to exchange in the capillaries of our cardiovascular system.
Describe your findings making sure to properly cite all sources(use sources other than your notes) using the proper citation style as described in Sections 1-3 lab activities.
Procedure 4: Blood pressure is measured in millimeters of mercury (mm Hg). A typical blood pressure is 120/80 mm Hg, or “120 over 80.” The first number represents the pressure when the heart contracts and is called the systolic blood pressure. The second number represents the pressure when the heart relaxes and is called the diastolic blood pressure.
