Study Notes
Blood Composition
- Plasma makes up the largest proportion of blood.
- Red blood cells, white blood cells, and platelets are suspended in plasma.
Blood Cell Production
- Bone marrow is the site of blood cell production.
Immune Responses
- Antigens are markers found on the surface of infectious cells.
- Antibodies are proteins produced by the immune system to fight foreign cells.
Blood Disorders
- Anemia is a condition characterized by low oxygen levels in the blood, usually due to low hemoglobin levels.
- Agglutination is the clumping of blood cells, often triggered by incompatible blood types.
- Erythroblastosis fetalis is a disorder that occurs when a Rh-negative mother carries a Rh-positive fetus, particularly during a second pregnancy.
Blood Composition
- Plasma is the primary component of blood, comprising around 55% of its volume.
Hematopoiesis
- Bone marrow, a soft tissue found within bones, is the site of blood cell production.
Immune Response
- Antigens, unique identifiers located on the surface of cells, trigger an immune response when foreign cells enter the body.
- Antibodies, specialized proteins produced by the immune system, recognize and bind to antigens, marking foreign cells for destruction.
Blood Disorders
- Anemia is a condition characterized by low levels of hemoglobin, the protein in red blood cells responsible for oxygen transport. This deficiency leads to reduced oxygen delivery to the body's tissues.
- Agglutination, the clumping together of blood cells, can occur when incompatible blood types are mixed, leading to complications.
- Erythroblastosis fetalis, a serious condition affecting newborns, can occur when a Rh-negative mother carries a Rh-positive fetus. The mother's immune system may develop antibodies against the fetal blood cells, leading to hemolysis (destruction of red blood cells) in the fetus.
