Hematology

Question 1

Components of blood in a hematocrit

Answer 1

Red blood cells, white blood cells, platelets, plasma

Question 2

Hematocrit

Answer 2

red blood cells in blood 45%

Question 3

Functions of blood

Answer 3

transports oxygen, nutrients, waste
regulates Ph, buffer
protects- prevents blood loss, infection
maintain temperature

Question 4

Hemoglobin

Answer 4

Protein in red blood cells, carries oxygen

Question 5

Importance of Iron

Answer 5

component of hemoglobin, this helps carry oxygen

Question 6

Life of erythrocytes

Answer 6

120 days

Question 7

What organs dispose/destroy old erythrocytes.

Answer 7

Spleen

Question 8

Plasma components

Answer 8

plasma proteins
albumin- osmotic pressure
globulins- attack foreign proteins and pathogens
fibrinogen- assists in blood clotting
lipoproteins- transport cholesterol to cells
83% water
1% other solutes (electrolytes)

Question 9

Formed elements of blood

Answer 9

Red blood cells (45%)
White blood cells
Platelets
Plasma(45%-65%)

Question 10

Types of Leukocytes

Answer 10

Never let monkeys eat bananas
Neutrophil, leukocyte, monocyte, eosinophil, basophil (most to least abundant)

Question 11

Platelets

Answer 11

Thrombocytes, Adhere to damaged site forming plug,

Question 12

What is hemostasis?

Answer 12

A. vascular spasms- constricts damaged blood vessel, seratonin enhances this
B. Platelet plug information- sticks to damaged endothelium and collagen, prostacyclin
C. COagulation- calcium dependent, prothrombin activator formed then converted to prothrombin into thrombin, thrombin catalyzes joining of fibrinogen molecules- mesh

Question 13

basophils

Answer 13

0.5% of WBC’s, histamine granules, 2-3 lobed, in connective tissues

Question 14

eosinophils

Answer 14

1-4% of leukocytes, 2 lobed, red granules, increased in allergic and parasitic responses

Question 15

monocytes

Answer 15

largest WBC, gray blue cytoplasm, kidney shaped nucleus, go into macrophages

Question 16

macrophage

Answer 16

Found in WBC, especially at sites of infection

Question 17

lymphocytes

Answer 17

in lymph tissues, T cells act against infection cells + tumor cells, B cells help to produce antibodies, increased in infections

Question 18

plasma

Answer 18

non-living fluid matrix, has fagl (fibrinogen- helps with clotts, albumin- osmotic pressure, flobulins- attacks foreign proteins, lipoproteins- transport cholesterol)

Question 19

hematopoiesis

Answer 19

red blood cells made in red bone marrow, life span of 100-120 days, removed by spleen, liver macrophages destroy, degraded to bilirubin

Question 20

red bone marrow

Answer 20

where red blood cells are made

Question 21

phagocytosis

Answer 21

ingestion of bacteria by phagocytes and protozoans, eliminating foreign substances

Question 22

neutrophils

Answer 22

cytoplasm stains pale lilac, 3-6 lobed nucleus, increased in
bacterial infection

Question 23

plasma proteins

Answer 23

fagl (fibrinogen- assists in blood clot, albumin- osmotic pressure, globulins- attack foreign proteins, lipoproteins- transport cholesterol)

Question 24

embolus

Answer 24

moving thrombus, coumadin (prevents blood clots)

Question 25

thrombocytes

Answer 25

blood clotting proteins

Question 26

leukocytes

Question 27

fibrinogen

Answer 27

Protein produced in liver that helps clotting

Question 28

hemostasis

Answer 28

blood clotting, vascular spasms, platelets stick to collagen and damaged andotheleum, then calcium dependent reaction, prothrombin activator made and converts prothrombin into thrombin

Question 29

Where are red blood cells made?

Answer 29

Red bone marrow

Question 30

Where are white blood cells made?

Answer 30

Bone marrow

Question 31

Red blood cells are destroyed in....

Answer 31

Spleen
