Blood Components and Blood Tests Quiz

An Overview of Blood Components and Blood Tests

Plasma makes up 55% of total blood, consisting of 91% water, 7% proteins, and 2% other components.
Albumin, comprising 58% of plasma proteins, maintains water balance, while globulins (38%) help the immune system and fibrinogen (4%) aids in clot formation.
Formed elements, which make up 45% of total blood, consist of cells and cell fragments, including erythrocytes, leukocytes, and thrombocytes.
Hematopoiesis is the process that produces formed elements, occurring in various fetal tissues and red bone marrow after birth.
Stem cells called hemocytoblasts differentiate into different cell lines, eventually forming particular types of formed elements.
Red blood cells (RBCs) are disk-shaped with thick edges and live for 120 days; they lack nuclei and contain hemoglobin, which transports oxygen.
White blood cells (WBCs) lack hemoglobin, are larger than RBCs, and contain nuclei; they fight infections and include granulocytes (neutrophils, eosinophils, and basophils) and agranulocytes (monocytes and lymphocytes).
Clots are networks of fibrin proteins that trap blood and fluids, activated by clotting factors produced in the liver and requiring vitamin K.
Anticoagulants, such as heparin and antithrombin, prevent clots from forming and spreading.
Blood groups are named according to antigens on the surface of erythrocytes; type O is a universal donor, while type AB is a universal recipient.
Rh positive blood indicates the presence of Rh antigens, which can cause hemolytic disease of the newborn if a Rh- mother is exposed to Rh+ blood; this can be prevented by treating the mother with RhoGam.
Blood tests, such as a complete blood count (CBC) and prothrombin time (PT), provide information on blood components and their functions, as well as potential disorders such as anemia, leukopenia, and leukocytosis.
