What constitutes formed elements?
red blood cells
white blood cells
platelets
What are stem cells?
divide and give rise to all the formed elements
Where do all formed elements originate from?
stem cell in the red bone marrow
What is the function of Red Blood Cells (RBCs; erythrocytes)?
transport oxygen and carbon dioxide
What is the function of Neutrophils (a type of white blood cell)?
consume bacteria by phagocytosis
What is the function of Eosinophils (a type of white blood cell)?
consume antibody-antigen complex by phagocytosis: attack parasitic worms
What is the function of Basophils (a type of white blood cell)?
Release histamine, which attracts white blood cells to the site of inflammation and widens blood vessels
What is the function of Monocytes (a type of agranulocytes)?
give rise to macrophages, which consume bacteria, dead cells, and cell parts by phagocytosis
What is the function of Lymphocytes (a type of agranulocytes)?
attack damaged or diseased cells or disease causing organisms; produce antibodies
What is the function of Platelets?
play role in blood clotting
Red blood cells (RBCs) are also known as ____________
erythrocytes
red blood cells (RBCs) carry about 23%of the blood’s total _______ ________
carbon dioxide
each red blood cell is packed with ___________
hemoglobin
What is hemoglobin?
the oxygen-binding pigment responsible for the cells’ red color
the hemoglobin molecule binds 200 times more readily to ________ _________
carbon monoxide
What happens when carbon monoxide binds to the oxygen-binding sites on hemoglobin?
it blocks oxygen from binding to it, preventing the blood from carrying life-giving oxygen to the cells
the compound formed when hemoglobin binds with oxygen is called ____________
oxyhemoglobin
The structure of hemoglobin:
-each hemoglobin molecule consists of four __________ ______ (globins)
- each polypeptide chain contains a _____ _____ with an iron atom that binds to oxygen
- each hemoglobin molecule can carry up to ____ molecules of oxygen
polypeptide chains
heme group
four
The structure of hemoglobin:
-each hemoglobin molecule consists of ____ polypeptide chains (globins)
- each polypeptide chain contains a heme group with an _____ atom that binds to _______
- each hemoglobin molecule can carry up to four molecules of _______
four
iron
oxygen
the production of red blood cells is regulated by a negative feedback relationship between the oxygen-carrying capacity of the blood and the production of ____________
erythropoietin
What are the steps of erythropoietin?
(1) erythropoietin stimulates the red bone marrow to produce more red blood cells
(2) more red blood cells are produced
(3) increased oxygen delivery to tissues
(4) inhibits erythropoietin release
(5) decreased oxygen delivery to tissues
(6) a decreased oxygen delivery to the kidney stimulates the kidney to release erythropoietin
(7) increases erythropoietin release
the _____ and ______ are the “graveyards” where worn-out red blood cells are removed form circulation
liver
spleen
the remaining part of the heme is degraded to a yellow pigment, called ________, which is excreted by the liver in bile
bilirubin
White blood cells are also known as __________
leukocytes
Where are white blood cells produced?
in the red bone marrow
certain types of white blood cells may then engulf the “offender” in a process called ___________
phagocytosis
What are the 2 types of white blood cells?
(1) Granulocytes
(2) Agranulocytes
Is this a Granulocytes or Agranulocytes:
have granules in their cytoplasm
Granulocytes
Is this a Granulocytes or Agranulocytes:
lack cytoplasmic granules or have very small granules
Agranulocytes
What are the different types of granulocytes?

Which type of granulocyte is this:
immediately begin to engulf microbes by phagocytosis
neutrophils
Which type of granulocyte is this:
dead neutrophils make up pus
neutrophils
Which type of granulocyte is this:
important against parasites
eosinophils
Which type of granulocyte is this:
lessen allergies
eosinophils
Which type of granulocyte is this:
play a role in some allergic reactions
basophils
Which type of granulocyte is this:

basophils
What are the different types of agranulocytes?
monocytes
lymphocytes
What is the difference between B lymphocytes and T lymphocytes?
B lymphocytes- give rise to plasma cells, which, in turn, produce antibodies
T lymphocytes- specialized white blood cells that play roles in the body’s defense mechanism
What are platelets?
are essential to blood clotting
Platelets are also called __________
thrombocytes
What is anemia?
a condition in which the blood’s ability to carry oxygen is reduced, can result from too little hemoglobin, too few red blood cells, or both

Infectious mononucleosis (mono)
Leukemia
What are the symptoms of anemia?
