Blood regulates pH
-
Blood maintains body temperature
-
Blood protects against foreign substances.
-
Blood does not produce bile
-
Normal blood pH range: 7.35-7.45
-
Blood maintains body temperature by regulating the flow of warm blood, shunting it to the interior or skin.
-
White blood cells protect against foreign substances
Section 2: Composition of Blood
-
Plasma accounts for 55% of blood volume
-
The primary component of plasma is proteins.
Section 3: Formed Elements
-
Erythrocytes (red blood cells) lack a nucleus.
-
Lifespan of red blood cells: 90-120 days
-
Red blood cells transport oxygen and carbon dioxide.
-
White blood cells are categorized into granulocytes and agranulocytes
- Granulocytes include neutrophils, eosinophils, and basophils.
- Agranulocytes include lymphocytes and monocytes.
-
Neutrophils are the most abundant type of white blood cell.
-
Platelets are fragments of megakaryocytes.
Section 4: Hemoglobin and Gas Transport
-
Iron is essential for oxygen binding in hemoglobin.
-
Oxyhemoglobin is the form of hemoglobin bound to oxygen.
-
Carbonic anhydrase converts carbon dioxide and water into bicarbonate in red blood cells.
Section 5: Hematopoiesis
-
All formed elements in the blood are derived from hematopoietic stem cells.
-
Proerythroblasts give rise to red blood cells.
-
Erythropoietin stimulates red blood cell production.
Section 6: White Blood Cells and Immunity
-
Neutrophils are primarily responsible for fighting bacterial infections.
-
Monocytes become macrophages in tissues.
-
Lymphocytes are divided into B cells and T cells.
-
Eosinophils increase in number during parasitic infections.
Section 7: Hemostasis
-
Vascular spasm is the first step in hemostasis.
-
Fibrin forms the meshwork in blood clots.
-
Platelets form platelet plugs during hemostasis.
Section 8: Hemoglobin Breakdown
- Red blood cells are broken down by macrophages in the spleen after 120 days in circulation.
- Globin (part of hemoglobin) is broken down into amino acids.
- Bilirubin is a breakdown product of heme, excreted in bile.
Section 9: Gas Transport
- Approximately 98.5% of oxygen is transported bound to hemoglobin.
Section 10: White Blood Cells
