Hematologic System Review of the Components 1) What is Plasma? What is Serum? Plasma is an aqueous liquid containing organic and inorganic elements, such as sodium and potassium, whereas serum is plasma that has been allowed to clot in the lab in order to remove things such as fibrinogen and other clotting factors that could possibly interfere with diagnostic tests 2) What is Plasma Protein? Albumin and globulins are the two major groups of plasma proteins that are produced by the liver and can be found in the plasma. 3) What is Albumin? Albumin makes up more than half of our plasma protein and serves as a carrier molecule for the abnormal and normal components found in blood and drugs that plays a vital role in regulating water and solute passing through capillaries. Albumin also serves to maintain the critical colloid osmotic pressure that is needed to regulate fluid and electrolyte passage. 4) What are globulins? Globulins are considered the remaining plasma proteins and are classified by their properties in an electric field and by their movement related to albumin. 5) Cellular Components of Blood (What are they and what are their main functions) A. Erythrocytes Erythrocytes are the red blood cells that are responsible for gas transportation to and from the tissue cells and lungs B. Leukocytes Leukocytes are our white blood cells that serve as our body’s defense mechanisms. Structure : a. Granulocytes Have many membrane bound granules in the cytoplasm that contain enzymes used for killing and catabolizing organisms during phagocytosis, as well as containing mediators with digestive enzymes released during specific stimuli. They move by migrating through vessel walls and then to sites where they are needed.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
