Study Notes
Blood Functions in Transport
- Blood serves as a transport system for regulatory molecules, including hormones and enzymes, which help regulate various bodily functions.
- These regulatory molecules travel through the bloodstream, allowing for communication between different organs and tissues.
Blood and Body Temperature Regulation
- Blood contributes to the maintenance of body temperature through the process of thermoregulation.
- It redistributes heat by adjusting blood flow to the skin; increased flow in warm conditions and reduced flow in cold conditions to conserve heat.
Liquid Matrix of Blood
- The liquid matrix of blood is called plasma.
- Plasma comprises about 55% of total blood volume, containing water, electrolytes, proteins, hormones, and waste products.
Meaning of 'Blue Bloods'
- The term 'blue bloods' refers to individuals from noble or aristocratic backgrounds.
- It originates from the visibility of veins through fair skin, often associated with higher social status in historical contexts.
Blood's Role in Immune Protection
- Blood protects against foreign substances using white blood cells and antibodies.
- White blood cells identify and neutralize pathogens, while antibodies bind to specific antigens to facilitate their removal from the body.
