Study Notes
Blood Cells and Functions
- Endothelial cells repair damaged blood vessels and provide growth factors for healing and repair.
- Neutrophils primarily engulf and digest foreign particles and bacteria.
- Leukopenia is a condition characterized by a low white blood cell count.
Lymphocytes
- Lymphocytes are essential in the immune response, leading to plasma cells and antibodies.
Basophils
- Basophils primarily release histamine during allergic reactions.
Blood Plasma
- Blood plasma carries nutrients, hormones, gases, waste products, and proteins throughout the body.
- The normal hematocrit percentage in blood is 45-50% for males and 40-45% for females.
Lipid Transport
- Albumin is a plasma protein responsible for transporting fatty acids and steroid hormones.
Red Blood Cell Production
- Erythropoietin (EPO) stimulates the production of red blood cells due to low oxygen levels.
Stem Cells
- Pluripotent stem cells become erythrocytes, platelets, granular leukocytes, or monocytes.
Bone Marrow Biopsy
- A bone marrow biopsy is used to examine the bone marrow's cellularity, morphology, and function.
Lymphoma
- Lymphoma is a cancer of masses of malignant T and B cells that collect in lymph nodes, spleen, liver, and other tissues.
Thrombocytopenia
- Thrombocytopenia is a condition characterized by too few platelets and poor clotting, leading to excessive bleeding.
Blood Clotting
- Thrombin triggers the formation of a blood clot of a mesh of fibrin.
- Vitamin K is required by the liver for many clotting factors.
- Heparin opposes coagulation by inhibiting the conversion of prothrombin.
Hemophilia
- Hemophilia is a disorder characterized by a deficiency of a clotting factor.
Thrombus
- If a thrombus breaks free into the bloodstream, it can travel to another part of the body and cause blockage.
Blood Types
- Type O blood is considered the universal donor.
Immune Response
- Agglutination is the process of RBC with foreign antigens triggering an immune response, causing RBC to clump together.
Platelets
- Platelets stop blood flow following damage to a vessel and secrete growth factor for repair.
Coagulation Pathways
- Tissue factor triggers the extrinsic pathway of coagulation.
- Collagen triggers the intrinsic pathway of coagulation.
