(2) Fetal- at 2–4 years old, fetal hemoglobin makes up less than 2% of the hemoglobin
(3) Adult- Only fetal hemoglobin remains

○ Transports carbon dioxide;
Carbaminohemoglobin
a relatively stable compound of hemoglobin
Carboxyhemoglobin
__ is produced by the incomplete combustion of gasoline, binds very strongly to the iron of hemoglobin.
Carbon monoxide
a disorder in which red blood cells
become sickle-shaped.
Sickle-cell disease
When will the red bone marrow produce red blood cell?
When there is a decrease in blood oxygen level
process by which new red blood cells
are produced.
Erythropoiesis
-rose from myeloid stem cells, derived from hemocytoblasts.
-produce red blood cells
Proerythroblasts
regulates red blood cell production.
Erythropoietin
Normal blood volume of male
Normal blood volume of female
In average adults, it is about 4–5 L in
females and 5–6 L in males.
What will happen if rbc would die?
fluid secreted from the liver into the
small intestine.
Bile
yellowish staining of the skin and the sclera of the eyes caused by a buildup of bile pigments in the blood and some tissues.
Jaundice
Also known as leukocytes, form a thin,
white layer of cells between the
plasma and the red blood cells.
White blood cells (WBCs)
White blood cells with large cytoplasmic granules and
lobed nuclei.
Granulocytes
Have granules, but so small that they cannot be
seen easily with the light microscope.
Agranulocytes
Three Types of Granulocytes
1. Neutrophil
2. Eosinophil
3. Basophil
Two types of agranulocytes:
1. Lymphocytes
2. Monocytes
produce basophils, eosinophils, and neutrophils
myeloblast
produce monocyte
monoblasts
produce platelet
megakaryoblasts
give rise to lymphocytes
Lymphoid stem cells
Three characteristics allow white blood
cells to carry out their function of
protection:
(1) Ameboid movement
(2) Diapedesis
(3) Chemotaxis
-type of movement that allows whiteblood cells to have a more directed movement
- like an amoeba
Ameboid movement
ability of WBCs to leave the blood and
enter other tissues.
Diapedesis
Attraction of WBCs to foreign materials
or dead cells within the tissue.
CHEMOTAXIS
accumulation of dead white blood cells
and bacteria, along with fluid and cell
debris.
Pus
THE FIVE TYPES OF WBCs:
1. Neutrophils
2. Eosinophils
3. Basophils
4. Lymphocytes
5. Monocytes
the first line of defense; first WBCs to
respond to infection.
NEUTROPHILS
class of enzymes which are capable of
destroying certain bacteria.
lysozymes
are important in the defense against
certain worm parasites.
EOSINOPHILS
Increase in number in tissue when experiencing inflammation, such as during allergic reactions
EOSINOPHILS
Releases histamine, which promotes inflammation, and
heparin, which prevents clot formation
Basophil
Produces antibodies and other chemicals responsible for
destroying microorganisms; contributes to allergic reactions,
Lymphocyte
Phagocytic cell in the blood; leaves the blood and becomes a
macrophage
Monocyte
Type of Lymphocyte that is stimulated by bacteria or
toxins to divide and form cells that produce antibodies
B cells
type of lymphocyte protect against viruses and other intracellular microorganisms by attacking and destroying the cells in which they are found.
T cells
Platelets are also called__
thrombocytes
the cessation of bleeding.
Hemostasis
Hemostasis involves three processes:
(1) vascular spasm,
(2) platelet plug formation, and
(3) coagulation.
the immediate but temporary constriction
of a blood vessel.
VASCULAR SPASM
accumulation of platelets that can seal
small breaks in blood vessels.
PLATELET PLUG FORMATION
low oxygen level in blood
Hypoxemia
Low oxygen levels of tissues
hypoxia
___ is called when platelets stick ti exposed collagen in damaged blood vessel wall
platelet adhesion
occurs when fibrinogen receptors on activated platelets bind to fibrinogen, connecting the platelets to one another. The accumulating mass of platelets forms a platelet plug.
Platelet Aggregation
protein that forms the fibrous network
of the blood clot.
Fibrin
is required for the formation of many of the factors involved in blood clot formation.
Vitamin K
prevent unwanted clotting.
Anticoagulants
Examples of anticoagulants in the blood:
1. Antithrombin
2. Prostacyclin
a plasma protein produced by the liver,
slowly inactivates thrombin.
Antithrombin
-convert the soluble plasma protein fibrinogen to the insoluble protein fibrin.
Thrombin
converts the soluble plasma protein prothrombin to the
enzyme thrombin.
Prothrombinase
○ a prostaglandin derivative produced by
endothelial cells.
○ It counteracts the effects of thrombin
by causing vasodilation and inhibiting
the release of clotting factors from
platelets
Prostacyclin
a plasma protein produced by the liver,
slowly inactivates thrombin.
Antithrombin
a process whereby the blood clot condenses into a denser, compact structure.
Clot Retraction
process that dissolves the blood clot
Fibrinolysis
the transfer of blood or blood components from one individual to another.
Transfusion
introduction of a fluid other than blood, such as a saline or glucose solution, into the blood.
