Blood and immune Flashcards
components of the immune system
Blood components, different types of white blood cells and antibody molecules.
Blood volume of the average male
5 to 6 litres (depending on size)
Blood volume of the average female
4 to 5 litres (depending on size)
How much blood circulates through the heart per day?
14000 Litres
Circulation time and 1 beat of the heart circulates how much blood
Circulation time: 1 minute
1 beat= 70mL
Circulation through blood capillaries and blood vessels
Slow through capillaries due to smaller size (site of diffusion) and fast through the blood vessels.
Function of blood
1, Transportation (CO2 and O2, hormones, waste, nutrients and heat)
- Regulation (pH, temperature, salinity)
- Protection (leakage control system: clotting and immune system: surviellence circuit- white blood cells and antibody molecules).
Components of blood
55% plasma and 45% formed elements
Formed elements is composed of…
more than 99% RBC (5-6 million) and the rest white blood cells including 70% neutrophils, 22% lymphocytes, platelets (250,000-400,000)
Plasma is composed of…
91.5% water, 7% proteins, ions.
Proteins include albumins- 54%
globulin 38% (immunoglobulin= antibody molecule)
Within a sample of blood there are three layers. These include…
- plasma (less dense)
- Buffer coat (white blood cells)
- Red blood cells (most dense)
Blood makes up how much percentage of the whole body?
8%
Types of proteins within blood plasma include
Albumins (54%)
globulins (38%)
Fibrinogen (7%)
all other (1%)
Types of other solutes within blood plama
Electrolytes, nurtrient, gas, regulatory substances, vitamins, waste products.
Types of white blood cells within formed elements…
neutrophils- 60-70% lymphocytes - 20-25% monocytes- 3-8% Eosiniphils 2-4% Basophils- 0.5- 1.0%
