Blood

Question 1

A fluid connective tissue consisting of blood cells and platelets

Answer 1

Blood

Question 2

(Blank) transports gases (O2 and CO2) while (Blank) fight off infection

Answer 2

Red Blood Cells; White Blood Cells

Question 3

55% of whole blood; Least dense; contains water, proteins(albumins, globulins, fibrinogen) other solutes (electrolytes, nutrients, gases, waste products)

Answer 3

Plasma

Question 4

Contains platelets and leukocytes; <1% of whole blood

Answer 4

Buffy Coat

Question 5

44% of whole blood; Most dense component

Answer 5

Erythrocytes

Question 6

Percentage of volume all formed elements in the blood, which is attributed mainly by the percentage of volume of red blood cells

Answer 6

Hematocrit

Question 7

The most abundant of the plasma proteins, they help retain water in the blood and also help transport hormones

Answer 7

albumins

Question 8

Transport lipids but the immunoglobulins are produced by defense cells to help protect the body from pathogens that may cause disease

Answer 8

globulins

Question 9

Helps with clot formation

Answer 9

Fibrinogens

Question 10

Lack nuclei and organelles; Contain hemoglobin (binds oxygen and carbon dioxide) ; average lifespan is 120 days (Usually broken down in liver)

Answer 10

Erythrocytes

Question 11

(Blank) produce antibodies to surface antigens not found on an individuals red blood cells

Answer 11

White Blood Cells (B-lymphocytes)

Question 12

antibodies bind to the surface antigen of the transfused erythrocytes and clumps of erythrocytes and bind together

Answer 12

agglutination

Question 13

Also called white blood cells; able to move out of blood vessels and into tissue (via diapedesis); divided into two groups granulocytes and granulocytes

Answer 13

Leukocytes

Question 14

leave the blood vessels and enter tissue spaces where they phagocytize infectious pathogens (especially bacteria); Most abundant

Answer 14

Neutrophils

Question 15

They phagocytize antigen-antibody complexes and release chemical mediators that attack parasitic worms; 2nd to the last in abundance

Answer 15

Eosinophils

Question 16

release histamine (Vasodilator) and heparin (anti-coagulant) during an inflammatory or allergic reaction; least abundant

Answer 16

Basophils

Question 17

Three types- T,B and Natural Killers; attack pathogens and abnormal/ infected cells. They also coordinate immune cell activity and produce antibodies; 2nd most abundant

Answer 17

Lympocytes

Question 18

They can exit blood vessels (becoming macrophages) and phagocytize pathogens (bacteria, viruses and cellular debris; 3rd most abundant

Answer 18

Monocytes

Question 19

Along with fibrin, form clots in response to damage, a low (blank) thrombocytopenia- makes one prone to bleeding; megakaryocytes, found in red bone marrow

Answer 19

Platelets

Question 20

Production of blood cells; occur in red bone marrow; can produce myeloid or lymphoid stem cells; myeloid stem cells produce all other blood cells than lymphocytes

Answer 20

Hemopoiesis
