What are the 4 ways a blood borne pathogen could enter the body's blood stream?
Ingestion
Inhalation
Absorption
Skin to blood contact
Injection
I choose abc and d am I corrct6?
skin is a tough barrier, however, injection is definitely getting to the blood
Am I right ? Or is it not ingestion
I think Bob P's answer meant you were right.
Actually, you are partly correct. The correct answer is a, c, and d. The four ways that a blood-borne pathogen could enter the body's bloodstream are:
a) Ingestion: This occurs when a person ingests contaminated food or drinks. Blood-borne pathogens can be present in raw or undercooked meat, unpasteurized milk, or contaminated water.
c) Absorption: This refers to the entry of blood-borne pathogens through mucous membranes or broken skin. For example, if you have a cut or a sore and come into contact with infectious blood or bodily fluids, the pathogens can enter your bloodstream.
d) Skin to blood contact: This occurs when intact skin comes into contact with infected blood or bodily fluids. Although intact skin acts as a protective barrier, any cuts, abrasions, or punctures can provide an entry point for blood-borne pathogens.
Inhalation and injection, which you mentioned as b and e respectively, are not among the four ways that blood-borne pathogens enter the body's bloodstream. Inhalation refers to inhaling droplets or particles containing the pathogen, which is more relevant to airborne pathogens such as those causing respiratory infections. Injection refers to the deliberate introduction of pathogens through a needle or syringe, which is typically not as common as the other routes of infection in everyday situations.
So, to summarize, the correct answers are a, c, and d: ingestion, absorption, and skin to blood contact.
