CARDIOVASCULAR SYSTEM
Lecture 4
State the relative abundance of each of the five leukocytes
5,000 to 10,000 WBCs/μL with conspicuous nucleus
Travel in blood then migrate to connective tissue
Five different types that protect against pathogens (grouped according to
presence or absence of cytoplasmic granules):
1. Never - Neutrophils
2. Let - Lymphocytes
3. Monkeys - Monocytes
4. Eat - Eosinophils
5. Bananas - Basophils
Type
Cytoplasmic granules
Granulocytes
Neutrophils (60-70%)
Eosinophils (2-4%)
Basophils (<1%)
Agranulocytes
Lymphocytes (25-33%)
Monocytes (3-8%)
Describe the structural characteristics and functions of each of the five
leukocytes
WBC
Structure
Function
Neutrophils
(Increase in
bacterial
infections)
Fine granules in cytoplasm; 3 to 5
lobed nucleus
Phagocytosis of bacteria
Release antimicrobial
chemicals
Eosinophils
(Increase in
parasitic
infections or
allergies)
Nucleus has two large lobes
connected by a strand
Phagocytosis of
antigen-antibody
complexes, allergens
and inflammatory
chemicals
Release enzymes to
destroy parasites such
as worms
