pathogens and diseases
pathogens can be spread by bodily contact, fluids and airborne particles
They infect a host, reproduce themselves or replicate if it is a virus, spread from their host and infect other organisms . They also all have structural adaptations that make them successful at completing their life cycles, which enable them to cause further disease.
vaccinations: vaccinations involve injecting small amounts of dead or weakened pathogens. which carry antigens which produce anti bodies to attack. them even though the pathogen is hermless. as it is dead or inactive
pros to vaccine: help control communicable diseases. can prevent big outbreaks of diseases if large percent of population are vaccinated
-
fighting diseases: your immune system can attack pathogens, white blood cells can engulf foreign cells and digest them. this is called phagocytosis
producing anti-bodies: when some types of white blood cells come across foreign antigens they ill start to produce proteins called anti-bodies. to lock onto the invading cells so that they can be found and killed by white blood cells
anti bodies are then produced rapidly and carries round the body to find similar bacteria or viruses
drugs
painkillers are drugs that relieve pain. however don't actually tackle the cause of the disease or kill pathogens, they just help to relieve symptoms
other drugs to similar things- to reduce symptoms for example cold remadies don't cure a cold or tackle the underlying cause
anti-biotics work differently- they kill or prevent the growth of the bacteria without damaging your own body cells . different antibiotics kill different types of bacteria so its important to b treated with the right one
anti biotics dont destroy viruses(eg, flu or cold viruses) viruses reproduce using your own body cells which makes it difficult to produce a drug that destroys the virus without killing the body cells.
bacteria can be resistant to anti-biotics, bacteria can mutate and as a result some can be resitant to an anti-biotic. if you have a infection some bacteria might be resistant to anti-biotics. this means when you treat the infection only non-resitant strains will be killed.
