I:  leukocytes, volume, erythrocytes, suspended, thrombocytes,  tissue, plasma

   Blood is a specialized biological fluid (technically a ______________^1) consisting of red
   blood cells (also called RBCs or ______________^2), white blood cells (also called WBCs
   ______________^3) and platelets (also called ______________^4) suspended in a complex fluid
   medium known as blood ______________^5 - it is the liquid component of blood, in which the
   blood cells are ______________^6. It makes up about 55% of total blood ______________^7.

   II: clotting, hemoglobin, pathogens, oxygen, prevent, immune

   Erythrocytes (45.0% of blood volume) contain the blood's ______________^1 which (when
   oxygenated) gives blood its red color. They distribute ______________^2.

   Leukocytes (1.0% of blood volume) are part of the ______________^3 system; they destroy and
   remove old or aberrant cells and cellular debris, as well as attack infectious agents
   (______________^4) and foreign substances. 

   Thrombocytes (>1.0% of blood volume) are responsible for blood ______________^5 
   (coagulation), which stops blood from leaving the body and also helps to ______________^6
   bacteria from entering the body.

   III: pressure, banks, transfusion, hemorrhage, compatible, arteries, obstruct, conditions,
   wounds, deficiency

   Disorders of volume: ______________^1 can cause major blood loss. Damage to the internal
   organs can cause severe internal bleeding or ______________^2.  Anemia is a ______________^3
   of red blood cells and/or hemoglobin; it can require blood ______________^4. Several countries
   have blood ______________^5 to fill the demand for transfusable blood. A person receiving a
   blood transfusion must have a blood type ______________^6 with that of the donor.

   Disorders of circulation: atherosclerosis reduces the carrying capacity of ______________^7.
   It is a potential consequence of high blood ______________^8 (hypertension), excess of
   circulating lipids (hyperlipidemia), and diabetes mellitus. Thrombosis is unregulated
   coagulation which can ______________^9 vessels. The consequences of circulatory insufficiency
   can create many medical ______________^10 such as ischemia, tissue necrosis and gangrene.

   IV: sepsis, transmitted, hemophilia, malaria, hepatitis, minor

   Disorders of coagulation: ______________^1 is a genetic illness that causes dysfunction in one
   of the blood's clotting mechanisms. This can allow otherwise ______________^2 wounds to be
   life-threatening.

   Infectious disorders of blood: HIV, the virus which causes AIDS, is ______________^3 through
   contact between blood, semen, or the bodily secretions of an infected person. ______________^4
   B and C are transmitted primarily through blood contact.

   Bacterial infection of the blood: this is bacteremia or ______________^5. Viral infection is
   viremia. ______________^6 is blood-borne parasitic infections.
