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
- Transportation:
- Oxygen (O2)
- Carbon dioxide (CO2)
- Nutrients
- Hormones
- Waste products
- Heat
- Regulation:
- Body temperature
- ECF pH
- Osmotic pressure
- Buffer systems
- Respiratory regulation
- Renal function
