Study Notes

Blood Composition

Blood is a connective tissue made up of cellular elements and an extracellular matrix.
The cellular elements, also known as the formed elements, include:
- Red blood cells (RBCs)
- White blood cells (WBCs)
- Platelets (cell fragments)

Blood Characteristics

Blood is denser and thicker than water.
It has a sticky and metallic texture.
Its freezing point is 0.50°C.
Blood can be classified as:
- Bright red (O2-rich)
- Dull red (O2-poor)
The pH of blood ranges from 7.35 to 7.45.
The normal temperature of blood is 38°C.
Blood constitutes approximately 8% of an adult's body weight.

Blood Volume

Adult males typically have 5-6 liters of blood.
Females typically have 4-5 liters of blood.

Functions of Blood

- Oxygen (O2)
- Carbon dioxide (CO2)
- Nutrients
- Hormones
- Waste products
