Study Notes
Functions of Blood
- Blood performs essential functions categorized into transportation, regulation, and protection.
- It transports oxygen and carbon dioxide between lungs and tissues for gas exchange.
- Nutrients from the gastrointestinal tract and hormones from endocrine glands are carried by blood.
- Blood aids in regulating body temperature and fluid levels, maintaining homeostasis.
Composition of Blood
- Blood comprises formed elements (red blood cells, white blood cells, platelets) and plasma.
- Plasma consists of various proteins and solutes dissolved in a liquid medium.
- The average adult has approximately four to six liters of blood circulating within the body.
Physical Characteristics of Blood
- Blood is a warm, alkaline, and viscous fluid essential for various physiological functions.
- The composition of blood changes continuously as it circulates, delivering and removing cells, ions, and molecules.
- Blood tests can provide critical diagnostic information for health assessment.
Protection Mechanisms
- Leukocytes and plasma proteins play vital roles in protecting the body against harmful substances through the immune system.
- Platelets and plasma proteins are involved in preventing blood loss and facilitating healing processes.
Blood Bank Technician Career Path
- Blood bank technicians sample and test donated blood for compatibility and infectious agents.
- A thorough understanding of blood composition and the significance of matching blood types is crucial.
- Universal precautions must be practiced to prevent exposure to potentially infectious bodily fluids.
