    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.
