Study Notes
-
Blood is a type of connective tissue that plays a crucial role in the cardiovascular system, with various functions including transport of materials, protection, and regulation.
-
Blood is composed of a liquid matrix (plasma) and cells scattered throughout, with plasma making up about 55% of the total blood volume.
-
The plasma is primarily composed of water, with various substances dissolved in it, including ions (sodium, potassium, calcium), nutrient molecules (glucose, amino acids), proteins (albumin, antibodies), clotting factors, and waste products (carbon dioxide, urea).
-
Plasma proteins, such as albumin, play a crucial role in osmotic regulation, ensuring cells maintain their shape and size.
-
Hormones are transported through the plasma, sometimes bound to protein carrier molecules and sometimes floating freely.
-
The formed elements or cellular portion of the blood makes up about 45% of the blood volume and consists of cells produced in the red bone marrow.
-
Red blood cells (RBCs or erythrocytes) are the majority of the formed elements, accounting for around 98-99% of the cellular portion.
-
White blood cells (WBCs or leukocytes) are an important immune component of the blood, while platelets (thrombocytes) are crucial for blood clotting.
-
Serum is the plasma without clotting factors, obtained by allowing the blood to clot and then spinning it down.
-
Serum can be used for various purposes, including the production of anti-sera containing antibodies.
