Blood Functions and Components

Blood serves to transport oxygen and carbon dioxide, regulate body temperature, and maintain pH balance and fluid homeostasis.
The three formed elements in blood are erythrocytes (red blood cells), leukocytes (white blood cells), and thrombocytes (platelets).

Albumins and Their Role

When albumins leak from blood vessels or are lost in urine, it can lead to edema due to loss of oncotic pressure, affecting fluid distribution in tissues.

Plasma Proteins

The largest component of globulins in plasma proteins is immunoglobulins (antibodies), crucial for immune responses.

Clotting Process

Thrombin, a key enzyme, converts soluble fibrinogen into insoluble fibrin during the process of blood clotting, forming a stable clot.

Formed Elements and Distinctions

Components that are NOT formed elements of blood include plasma (the fluid portion of blood).
The distinguishing characteristic of platelets at the electron microscopic level is their small size and the presence of granules.

Staining Techniques

Wright's stain produces different colors on various cellular components, allowing for differentiation among types of blood cells.

White Blood Cell Activity

White blood cells (WBCs) exit the bloodstream to enter tissues through a process called diapedesis, where they squeeze through endothelial cells of blood vessels.

Serum vs Plasma

The main difference between serum and plasma is that serum is the fluid component that remains after blood has clotted, while plasma contains clotting factors and is obtained from unclotted blood.
