The four components of blood (4p)
White blood cells <1%
Platelets <1%
Ref blood cells 45%
Plasma 55%
Components of blood plasma (8p)
Water
Dissolved nutrients
Oxygen
Carbon dioxide
Urea
Hormones
Dissolved mineral ions
Plasma proteins
Function of water in blood plasma (2p)
-Solvent to dissolve other substances
-Transport other substances
Dissolved nutrients in blood plasma (4p)
Glucose
Amino acids
Fatty acids/glycerol
Vitamins
Use of vitamins in blood plasma
Helps to regulate metabolism inside cells
Use of glucose in blood plasma (2p)
Respiration
To make new carbohydrates
Use of amino acids in cells
To make new proteins
Use of fatty acids/glycerol
To make new fats/lipids
Uses of oxygen in blood plasma
Used for aerobic respiration
Uses of carbon dioxide in blood plasma
Waste product
Use urea in blood
Used for the breakdown of excess proteins
Use of hormones in the blood
Involved in homeostasis
Control changes in the body
Uses of dissolved mineral ions in the blood (2p)
Control water movement
Regulates metabolism
Use of plasma proteins in the blood (2p)
Help blood clot
Help with reabsorption of fluid from tissues to blood
Features of red blood cells under a microscope (3p)
Small in size
Numerous
Pink/red in colour
White blood cells featured under a microscope (3p)
Larger in size
Fewer in numbers
Nucleus stained for contrast
Where are all the blood components produced
Bone marrow
Function of red blood cell
Bind to oxygen irreversibly
Two types of white blood cells (2p)
Phagocytes and lymphocytes
Phagocyte function
Swarm to site of infection
Phagocyte adaptations
They can change shape yor squeeze out capillaries and reach the site of infection
Adapt of red blood cells (3p)
No nucleus
Haemoglobin
Bioconcave
Lymphocytes function
Produce antibodies
Lymphocytes adaptations (2p)
-Specific to one type of microbe
- Bind to antigens
