Blood: Nature and Origin
How is blood biologically classified, and from which embryonic germ layer is it derived?
How is blood biologically classified, and from which embryonic germ layer is it derived?
Classification: Blood is considered a highly specialized fluid connective tissue.
Composition: It consists of a fluid extracellular matrix called plasma and formed elements (cells and cell fragments).
Origin: It is mesodermally derived.
Function: It links, binds, and provides structural support by transporting oxygen, nutrients, and waste products continuously throughout the body.

Composition of Plasma
What is the physical nature and quantitative composition of blood plasma?
What is the physical nature and quantitative composition of blood plasma?
- Nature: It is a straw-coloured, viscous fluid.
- Total Blood Volume: Constitutes nearly 55% of total blood.
- Water Content: Accounts for 90-92% of plasma.
- Protein Content: Contributes 6-8% of plasma.
- Trace Elements: Contains small amounts of minerals (, , , , ), glucose, amino acids, and lipids.

Major Plasma Proteins
Name the three major protein types found in blood plasma and state their primary physiological functions.
Name the three major protein types found in blood plasma and state their primary physiological functions.
- Fibrinogens: Play a crucial role in blood coagulation (clotting) to prevent blood loss.
- Globulins: Primarily involved in the defense mechanisms of the body (e.g., immunoglobulins/antibodies).
- Albumins: The most abundant plasma proteins; they aid in maintaining the osmotic balance of the blood.
