Question 1

Eosinophil

Answer 1

2-4% of white blood cells
Nucleus dark blue w/ two lobes (bi-lobed)
Cytoplasmic granules large (red/orange)
Destroy parasitic worms; high during allergies
Made in bone marrow by myeloblasts

Question 2

Basophil

Answer 2

0.5-1% of white blood cells
Nucleus w/ U-shape
Cytoplasmic granules large (purple/blue)
Release histamine to vasodilate
Made in bone marrow by myeloblasts

Question 3

Monocyte

Answer 3

3-8% of white blood cells
Large nucleus w/ C-shape
No Cytoplasmic granules 
Become macrophages (phagocytic)
Made in lymphatic tissue by monoblasts

Question 4

Lymphocyte

Answer 4

25-45% of white blood cells
Nucleus dark/round and fills much of the cell
No Cytoplasmic granules
Made in lymphatic tissue by lymphoblasts

B lymphocytes = humoral immunity (antibodies)
T lymphocytes = cellular immunity (T-cells)

Question 5

Neutrophil

Answer 5

50-70% of white blood cells
Nucleus dark blue w/ 3 or more lobes
Small Cytoplasmic granules
Phagocytic
Made in bone marrow by myeloblasts
