Question

part iii. (3 pts ea) fill in the blank with the term that best fits the description.

a. ____________________ oxygen and carbon dioxide carrying cell

b. ____________________ plasma protein that forms a clot to help the body stop bleeding

c. ____________________ name of factor that promotes rbc formation

d. ____________________ element forming \core\ of heme group

e. ____________________ most common plasma protein

f. ____________________ large cells that develop into platelets

g. ____________________ a deficiency in number of rbcs or decreased hemoglobin content of blood

h. ____________________ a deficiency in platelets

i. ____________________ vitamin required for proper clotting to occur

j. ____________________ process of blood cell breakdown

Explanation:

Identify blood cells and proteins

• Item a asks for the oxygen and carbon dioxide carrying cell. These are red blood cells, scientifically known as erythrocytes.
• Item b asks for the plasma protein that forms a clot to stop bleeding. This is fibrinogen, which is converted to fibrin during coagulation.
• Item e asks for the most common plasma protein. This is albumin, which maintains osmotic pressure.

Identify regulatory factors and elements

• Item c asks for the factor promoting red blood cell (RBC) formation. This hormone is erythropoietin (EPO).
• Item d asks for the element forming the "core" of the heme group. This is iron (\(\text{Fe}\)), which binds oxygen.

Identify platelet development and disorders

• Item f asks for the large cells that develop into platelets. These precursor cells are megakaryocytes.
• Item g asks for a deficiency in RBCs or decreased hemoglobin. This condition is anemia.
• Item h asks for a deficiency in platelets. This condition is thrombocytopenia.

Identify clotting vitamins and breakdown processes

• Item i asks for the vitamin required for proper clotting. This is Vitamin K, essential for synthesizing clotting factors.
• Item j asks for the process of blood cell breakdown. This is hemolysis.
