Study Notes
Blood
- Major functions: Transportation of nutrients, regulation of blood pH, protection against infectious disease, transportation of heat, and production of oxygen.
- Plasma composition: 91.5% water.
Plasma Proteins
- Disease Resistance: Globulins
- Blood Clotting: Fibrinogen
Blood Cell Development
- Hemopoiesis: The process of blood development.
- Megakaryoblast: Develops into platelets.
Red Blood Cells
- Major Function: Gas transport.
Jaundice
- Cause: Deposition of bilirubin in skin.
- Association: Excessive breakdown of red blood cells.
Erythropoiesis
- Stimulant: Erythropoietin (EPO).
Blood Cells
- Phagocyte: Neutrophil.
- Blood Clotting: Platelets.
- Inflammation/Hypersensitivity: Eosinophils.

Mediastinum: The anatomical region between the lungs, from sternum to vertebral column, and from the first rib to the diaphragm.
-
Pericardium: Membrane surrounding the heart.
-
Myocardium: Cardiac muscle tissue layer of the heart wall.
