PNB 2265 Lab Practical 1 | STUDY GUIDE
transport oxygen and nutrients to and from tissues
Blood
functions
removes cellular waste
formed elements of blood RBCs, WBCs, platelets
extracellular matrix of plasma
blood
What is the most RBCs
abundant cell type in the
blood?
RBCs
erythrocytes biconcave cells that deliver oxygen to tissues in the
body
Basophil nucleus type multi-lobed
Basophil function release chemicals that change blood pressure
Neutrophil nucleus type multi-lobed
respond to the site of an acute injury or infection and
Neutrophil function perform phagocytosis
Platelet nucleus type no nucleus
Platelet function cell fragment that helps form blood clots
Eosinophil nucleus type bi-lobed nucleus
, responds to allergens and chronic inflammation by
Eosinophil function releasing chemicals that change blood pressure
Eosinophil nucleus bi-lobed nucleus
WBCs are organized into 2 1)granulocytes
categories which are... 2)agranulocytes
contain many dark staining granules in the
granulocytes cytoplasm of the cell
Which WBCs are neutrophils, eosinophils, basophils
granulocytes?
Which WBCs are lymphocytes (B, T, NK cells) and monocytes
agranulocytes?
Agranulocytes don't contain granules
What percentage of 60%
WBCs are neutrophils?
What percentage of 25%
WBCs are lymphocytes?
What percentage of 10%
WBCs are monocytes?
What percentage of 3%
WBCs are eosinophils?
What percentage of
<1%
WBCs are basophils?
What is sickle cell
a hereditary condition in which abnormal hemoglobin
anemia?
is produced and results in the misfolding of RBCs
Why is sickle cell rigid & sticky sickle cells can get stuck in small
anemia problematic? blood vessels which can block blood flow and
oxygen to parts of the body
