Study Notes
Functions of Blood
- Blood transports oxygen from the lungs to tissues and carries carbon dioxide back to the lungs for exhalation.
- It delivers nutrients, electrolytes, and hormones to various parts of the body.
- Blood regulates body temperature, pH levels, and fluid balance within cells and tissues.
Components of Blood and Immune Response
- White blood cells (leukocytes) are primarily responsible for the immune response.
- They identify and neutralize pathogens like bacteria and viruses, playing a crucial role in protecting the body against infections.
Plasma Composition
- Plasma makes up approximately 55% of total blood volume.
- It is composed mainly of water, proteins, electrolytes, and waste products, serving as the medium for transporting substances.
Blood Clotting
- Platelets (thrombocytes) are the blood cells primarily involved in clotting.
- They aggregate at injury sites and release chemicals that promote clot formation, preventing excessive bleeding.
Blood Types
- Type O negative is known as the universal donor.
- This blood type can be transfused to patients of any blood group without causing adverse reactions due to the absence of A, B, and Rh antigens.
