Zoology 315 Mammalian Physiology
Introduction:
List the four basic tissues and the function each perfoms.
Water is a key factor in the internal environment. In which compartments of the body is water found? What portion of total body water is found in each compartment.
Be able to draw a general model of the human body that will show in simplified form how the cardiovascular, respiratory reanl, and digestive systems work in the organism. Indicate what substances move into or out of these organs.
What governs whether or not a substance moves between the different compartments of the body?
What is the difference between diffusion and osmosis?
What type of internal conditions does your body regulate? (give examples)
Define homeostasis.
List some examples of how the internal environment can be perturbed.
Explain how a positive feedback system--a negative feedback system work and give an example of each.( an example in your body and an example not related to your body)
What is the advantage of a positive feedback system? Its disadvantage?
Hemostasis
What are the four parts of hemostatis.
What is the purpose of vasospasm?
What are the events that lead to formation of the platelet plug? Be able to draw a flow diagram of the process. Know what the initiating event is and where positive feed back occurs.
Where do platelets come from? (cell type and where this cell is
found)-
what hormone regulates production?
What role does thrombaxane play in platelet plug formation?
What type of drug can interfere with platelet plug formation?
What normally stops platelet plug formation in the body?
What is coagulation?
What is the general model of the coagulation pathway.
Which components are always present in the blood?
What is the difference between the intrinsic and extrinsic pathways?
What is the benefit of a cascade type response?
What role does thrombin play in coagulation?
What role does vitamin K play in clotting?
Where are clotting factors produced? Where are they normally found?
Know the clotting cascade from factor X to clot formation.
List all the things that could be found in a clot.
List three ways your body prevents inappropriate clotting from occuring in your body. If a factor is invovled where did that factor come from?
What is involved in clot retraction and wound repair?
What is fibrinolysis? show a flow diagram of factors found in blood and the role they play.?
What is the problem in Hemophelia A? Why is this a problem?
Why do chronic alcoholics have hemostasis problems?
To demonstrate your understanding of hemostasis explain
