Blood Basics
These are the two main components of blood
What are plasma and formed elements?
This protein, found in red blood cells, is responsible for transporting oxygen
What is hemoglobin?
Unlike red blood cells, all white blood cells have this cellular structure
What is a nucleus?
Platelets are fragments of these large cells
What are megakaryocytes?
This membrane surrounds and protects the heart
What is the pericardium?
This is the percentage of water in blood plasma
What is over 90%?
This is the approximate lifespan of a red blood cell
What is 120 days?
These are the two categories of leukocytes, based on the presence of cytoplasmic granules
What are granulocytes and agranulocytes?
This hormone regulates the production of platelets
What is thrombopoietin?
These are the upper chambers of the heart
What are the atria?
This is the approximate temperature of blood in Fahrenheit
What is 100.4 degrees?
This is the term for the production of red blood cells
What is erythropoiesis?
This type of white blood cell is the most abundant and functions to phagocytize bacteria
What are neutrophils?
This is the first step in hemostasis
What is vascular spasm?
Blood passes from the right atrium into the right ventricle through this valve
What is the tricuspid valve?
This is the process by which white blood cells slip out of capillaries to mount an immune or inflammatory response
This is the process by which white blood cells slip out of capillaries to mount an immune or inflammatory response
This hormone regulates red blood cell production
What is EPO (erythropoietin)?
These are the three types of granular leukocytes (granulocytes)
What are neutrophils, eosinophils, and basophils?
This vitamin is required for the synthesis of four clotting factors by hepatocytes
What is Vitamin K?
The left atrium receives blood from these vessels
What are the pulmonary veins?
This is the term for a high white blood cell count
What is leukocytosis?
This condition results from having too many red blood cells
What is polycythemia?
This type of leukemia is characterized by the accumulation of mature white blood cells that do not die
What is chronic leukemia?
This is the term for a clot that forms in an unbroken blood vessel
What is thrombosis?
This groove on the surface of the heart contains the largest coronary blood vessels
What is the sulcus?
