Lab Report: Cardiovascular Anatomy

Please fill out this report and submit it to the dropbox. Do not hand in your own form. It will not be graded and you will receive a zero for the lab.

You must get all parts of the question correct to get credit for the question

* Please note that although you do not hand in items in observations, it is very important to do these as you may see some of these items on future/associated lab quizzes or be asked about some of these concepts on unit assignments. It is strongly recommended that you draw, label, diagram, etc. your observations or examples of the subjects covered in this lab as this encourages the learning process.*

Observing Blood

Observations: Please pay special attention to the shape, size, color, and any other distinguishing features of blood.


A.What are the components of blood?
The components of blood are plasma, platelets, red blood cells, and white blood cells. (Vass, 2007 pg. 63)

B.What are the functions of red blood cells? Name one blood cell disease and give a brief explanation the disease.
Red blood cells also known as Erythrocytes have a function to get oxygen to the cells and get the carbon dioxide out of the cells. (Vass, 2007 pg. 64) One blood cell disorder/disease is anemia. The most common type of anemia, also what I have, is iron-deficiency anemia. This is caused from losing to much blood and not eating enough iron. Iron is used in the body to make hemoglobin. Hemoglobin gives the red color to blood. Iron helps to carry the oxygen from the lungs to the rest of the body. (Saladin, 2010 pg. 694). C.List the five types of leukocytes and describe the function of each. (Saladin, 2010 pg. 701-704) Neutrophils- Destroy bacteria and to release antimicrobial chemicals. Eosinophils- Secrete chemicals that destroy parasites. They also destroy and get rid of foreign antigens that create allergies. Basophils-Secrete histamine and heparin. Histamine is used to speed up the flow of blood to injured tissue and heparin allows the flow of WBC’s to the area, while not allowing blood clots. Lymphocytes- Destroys foreign cells like cancer cells, allows for the immune system to remember things, secretes antibodies, and coordinates the action of the other immune cells. Monocytes- Destroy dead or dying foreign objects, cells, and matter. Alert the immune system of a pathogen being present.

Blood Typing

Observations: Pay attention to what happened when you mixed your blood with each of the antisera. Based on your results, what is your blood type? NO SUBMISSION


A.Describe how the ABO blood typing system works (be specific about the basis for ABO blood types, not how to do the experiment). Your blood type is determined by the presence of hereditary antigens. A person’s blood type is determined by genetics. If a person has a A type blood they have A agglutinins on the red blood cell surface and they have B type agglutinins as plasma antibodies. If a person has type B blood they have B agglutinins on the red blood cell surface and they have A type agglutinins as plasma antibodies. If a person has AB blood type they have both A and B agglutinins on the surface of the red blood cells and they have no plasma agglutinin. If a person has type O blood type they have no proteins on the red blood cell but the plasma antibodies are A and B agglutinins. (Vass, 2007 pg. 69)

B.Describe what would happen if type A blood were transfused into a person with type B blood (be specific). If a person with type A blood got transfused with type B blood, they would have a tranfusion reaction. This means that the red blood cells could block small blood vessels, hemolyze, and also can release their hemoglobin which can block the kidney tubules. (Saladin, 2010 pg. 698) C.What happens in the blood of an Rh-negative individual who is exposed to...
