NUR3196 - Module 12 Test| Questions
and 100% Correct Verified Answers
erythrocytes, leukocytes, platelets - Answer cellular components of in the hematologic
system (3)
Erythrocytes - Answer -red blood cells, most abundant cells in blood
-responsible for tissue oxygenation
-bioconcavity and reversible deformity
-life cycle is between 100-120 days
Leukocytes - Answer -white blood cells
-defend against infection and remove debris
-act in the tissues but are transported by circulation
-many diff types, each with their own important action.
Thrombocytes - Answer -platelets
-they are irregularly shaped cytoplasmic fragments and are essential for
blood coagulation and control of bleeding
metabolism
microorganisms
acid-base - Answer Chief function of the cells in the hematologic system:
-deliver substances needed for cellular ___
-remove wastes
,-defense against ___ and injury
-maintenance of ___ balance
bone marrow - Answer Soft, spongy tissue found in the cavities of bones, primarily
responsible for the production of blood cells through a process called
hematopoiesis. Red ___ produces red and white blood cells, as well as platelets.
lymphatic system - Answer Comprises lymph nodes, lymph vessels, and lymphoid
organs. It plays a crucial role in filtering and draining lymph (a clear fluid containing
white blood cells) from each region of the body, helping to remove waste products
and pathogens.
spleen - Answer Acts as a blood filter, removing damaged blood cells and foreign
particles. The spleen also stores platelets and white blood cells and is involved in
the immune response.
anemia
polycythemia vera - Answer RBC (erythrocytes): 4.2-6.2 million/ mm3
decreased = ?
increased = ?
leukopenia (immunocompromised)
leukocytosis (infection) - Answer WBC (leukocytes): 5000-10,000/ mm3
decreased = ?
increased = ?
thromocytopenia
thrombocythemia - Answer platelets (thrombocytes): 150,000-400,000/ mm3
, decreased = ?
increased = ?
blood clot - Answer a meshwork of protein strands that stabilizes the platelet plug and
traps other cells, such as erythrocytes, phagocytes, and microorganisms
Fibrinolysis
major
Plasmin - Answer The Fibrinolytic System:
-___ is initiated by the binding of plasminogen to fibrin.
-Although tissue plasminogen activator (t-PA) initiates intravascular fibrinolysis,
urokinase plasminogen activator (u-PA) is the ___ activator of fibrinolysis in tissue
(extravascular).
-___ digests the fibrin into smaller soluble pieces (fibrin degradation products). u-
PAR, Urokinase-like plasminogen activator receptor.
fibrinolytic system - Answer
homeostasis - Answer once the ___ is obtained, the clot is no longer needed.
shorten
platelets - Answer Clot retraction:
-fibrin stands ___; become denser and stronger to approximate the edges of the
injured vessel and site of injury
-facilitated by large numbers of ___ within the clot
clot degradation - Answer This occurs when the body naturally produces t-PA
(tissue plasma antigen) to break up the clot overtime.
