What are viruses and bacteria
They are part of the tiny organisms called microorganisms
They are too small to see
What can viruses and bacteria cause
Diseases and servers illness
What are some diseases caused by bacteria
- sore throat
- tuberculosis
- urinary tract infections
- syphills
- gonorrhoea
What are some diseases caused by viruses
- chicken pox
- AIDS
- Flu ( influenza )
- SARS
What are anti microbial agents
They are substances that prevents the growth and also kills microorganisms
What are the 3 types of anti microbial agents
- Antiseptics
- Disinfectants
- Antibiotics
What are antiseptics
These are chemical substances that are applied on living surfaces like skin to prevent the growth of microorganisms
( eg. prevents bacteria and fungi )
What are disinfectants
It is chemicals that are used on non living surfaces to prevent the growth of microorganisms
What are antibiotics
Antibodies are injected or is taken orally to kill microorganisms and prevent it from growing
What are vaccinations
Vaccinations help to prevent diseases that are caused by viruses
What are hereditary diseases
Hereditary diseases are passed down from one generation to the next
What are the causes of hereditary diseases
The mutant of the genes
What are the 3 examples of hereditary diseases
- thalassemia
- sickle cell anaemia
- colour blindness
What is sickle cell anaemia
It is a gene controlling haemoglobin in red blood cells at the birth of a child
What are the results of the sickle cell
This results in the formation of red blood cells that are sickle shaped
what is the difference between sickel red blood cells versus normal red blood cells
the sickel blood cell does not carry as much oxygen than normal red blood cells
what does sickel blood cell do
it cannot move smoothly through the blood cells
it can cause blockages in the blood vessels
it will not obtain sufficient oxygen
what is thalassemia
it is a hereiditary disease that is passed on from parents to their young
what does thalassemia involve
it involves the mutation of the gene that makes haemoglobin and it causes red blood cells to be destroyed
what does anaemic
it means one that is suffering from thalassemia does not have enough blood
what does anaemic result in
it results in the low level of haemoglobin and low count of red blood cells
what is colour blindess
it is one of the most common hereiditary diseases that the colour vision is controlled by the gene
what happens when the gene for our colour vision is damaged or have gone missing
these are special cells and if it is damaged or destroyed, the colour vision will be missing and will make the person color blind
