What percentage of blood is plasma? - ANS 55%
What are the three main blood cell types? - ANS Erythrocytes (RBCs), Leukocytes (WBCs),
Thrombocytes (platelets)
Where does hematopoiesis occur? - ANS Bone marrow
What does a CBC measure? - ANS RBCs, WBCs, platelets
What is primary hemostasis? - ANS Vessel constriction, platelet aggregation, plug formation
What is secondary hemostasis? - ANS Activation of clotting factors, fibrin mesh, stable clot
Which test monitors heparin therapy? - ANS aPTT(activated partial thromboplastintime)

, What labs are in a CMP(Complete metabolic panel)? - ANS BMP(basic metabolicpanel) +
Liver Function Tests, Albumin, Calcium
What is homeostasis? - ANS The ability of the body to maintain a stable internal
environment.
What major components does the CBC(Complete blood count) measure? - ANS RBCs, WBCs,
platelets, hemoglobin, hematocrit.
What are the body's first-line defense mechanisms? - ANS Physical barriers such as skin and
mucous membranes.
Which immune system response is fast but nonspecific? - ANS Innate immunity (neutrophils,
macrophages)
Which immune cells provide long-term memory and specific response? - ANS Lymphocytes
(B cells and T cells).
What is the function of red blood cells? - ANS Transport oxygen, carry CO■, maintain acid-
base balance
What is the function of white blood cells? - ANS Defend against infection and foreign
substances.
What is Hemostasis? - ANS Hemostasis is the process of preventing blood loss from intact
vessels and of stopping bleeding from a severed vessel, which requires adequate numbers of
functional platelets. Platelets nurture the endothelium and thereby maintain the structural
integrity of the vessel wall. Two processes are involved in arresting bleeding: primary and
secondary hemostasis
