Blood

1. Make a concept map of components of blood and the functions of blood and characteristics of blood.  For example, write down blood and draw a square or circle around.  Then draw a line attached to the square going away from the circle.  Write plasma at end of it and then draw branches off that line with all the characteristics and functions of plasma.  Draw a line for each of the formed elements and list the characteristics and functions for each of the elements (Visual).

2. Create a mnemonic for each of the hemopoietic stages for erythrocyte, the different leukocytes and platelets. (Aural, Read/write)

3. Draw a hormone feedback loop for EPO similar to what we did in 2113 lab. (V, Kinesthetic)

4. Write “Hemostasis: The Play” with four acts.  Characters or props could include: nociceptors, serotonin, ADP, thromboxane, platelets, Factor III or XII, fibrinogen, and fibrin. (R, A)

 

Heart

1. Draw a typical action potential of a neuron and label it with what gates are opening and closing and the direction of ion flow at the different stages.  Now draw and label the action potential that occurs in contractile cardiac muscle and conducting contractile muscle.  Make a list of differences between the different action potentials. (V, R)

2. Make a stack of cards each with a different event that occurs during the cardiac cycle, e.g., AV valves open, pressure in ventricles > pressure in arteries.  Make up a separate set of cards of the five different stages, e.g., quiescent period, atrial systole, etc. Mix up the event cards and lay the stage cards in a row.  Place the event cards under the correct stage card and order correctly under the stage. Ex: AV valves open under isovolumetric relaxation but placed last.  Try to do this without looking at the book or notes and thinking about why each event goes under each event. (V, K)

3. Imagine you are a red blood cell (Erin or Eric Erythrocyte).  Write or tell your story as you go through the heart during the cardiac cycle. (R, A)

4. Draw feedback loops for control of heart rate that involves input to the cardiac center from propioceptors, baroreceptors, chemoreceptors, and emotional stimuli.  (V, K)

 

Blood vessels

 

1. Draw a concept map of the different blood vessel types (arteries, capillaries and veins) with information on the branches about histology for each type. (V)

2. Write a poem for each of the blood vessel types. Possible styles: limericks (There once was vessel called artery…), haiku (3 lines: 5 syllables, 7 syllables, 5 syllables) or iambic pentameter (ask an English professor). (R) Read them out loud. (A).

3. Draw a mind map showing the different factors affecting blood flow.  Start with blood flow in middle with circle around it and then draw the factors that affect blood flow (blood pressure and peripheral resistance) around it. Draw arrows connecting these to blood flow and indicate whether they positively affect it or negatively affect it.  Then draw in any factors that affect these factors connecting whatever they affect and whether it is a positive or negative relationship. (V)

4. Capillary Exchange Critical Thinking: Predict what would happen to net movement of water, blood volume and/or fluid accumulation in tissues under the following situations:

   

a) A tumor in the liver resulted in the release of more plasma proteins than normal.

 

b) A person became hypotensive.

 

c) The lymphatic vessels became blocked.

 

5. Draw the normal flow of blood through the heart.  Now draw the flow of blood through the fetal heart.  (V)
