Monocytes
Lymphocytes

Question 10

6-12hes

Question 13

What is the half life of platelets

Answer 13

6-8 days

Question 14

What is the half life of RBCs

Answer 14

110-120 days

Question 15

What is the stem cell that produces all blood cells called

Answer 15

Hemocytoblast

Question 16

What does a hemocytoblast divide into

Answer 16

Common myeloid progenitor
Common lymphoid progenitor

Question 17

What does the common lymphoid progenitor produce

Answer 17

Lymphocytes

Question 18

Thrombocytes
Platelets
Erythrocytesnast cell
Basophils
Neutrophils
Eosinophils
Monocyte

Question 19

What is the marrow transit time for granulocytes

Answer 19

1 week

Question 20

What is the marrow transit time for erythrocytes

Answer 20

3-5days

Question 21

Where is b lymphocytes produced in birds

Answer 21

Bursa of fabricius

Question 22

What is endomitosis

Answer 22

Nuclear duplication without cell divisor

Question 23

What is the process of thromvopoiesis

Answer 23

Endomitosis happens and cell volume increases with each nuclear doviok
Megakaryocyte then forms, and pinches of it can come off from cytoplasm to form platelets

Question 24

What are the two neutrophil activities

Answer 24

Chemotaxis
Phagocytosis and killing

Question 25

How does oxygen independent killing of neutrophils work

Answer 25

Occurs at poor blood flow/ abscess

Uses lysozymes

Question 26

How does oxygen dependent killing of neutrons;hills work

Answer 26

Generates reactive oxygen species that damages bacterial membrane to kill them

Question 27

How re neutrophils involved in chemotaxis

Answer 27

Neutrophils have selection receptors that interact with selectins on endothelial cells so they express ICAM- 1 and VCAM- 1
Slows down the neutrophils passage
So the neutrophils can escape blood vessel and get to site of inflammation

Question 28

What species have heterophils

Answer 28

Rabbits
Reptiles
Avian

Question 29

What are heterophils

Answer 29

Functionally equivalent to neutrophils
Granules stain red

Question 30

What are the 6 stages of neutrophil development names

Answer 30

Myeloblast
Promuelocyte
Myelocyte
Metamyelocyte
Band neutrophil
Segmented neutrophil

Answer 31

Allergies
Parasites
Fibrosis

Answer 32

0-300

Question 33

When do you get most basophils

Answer 33

Allergy

Question 34

Where are mast cells found

Answer 34

Tissues

Question 35

Where are monocytes found

Answer 35

In blood not tissue
