What describes a function of a T-lymphocyte?

A They are only found in blood and secrete cytokines in response to infection.
B They can leave the blood and accumulate at sites of inflammation.
C They can leave the blood and secrete cytotoxins when exposed to bacteria.
D They circulate in the blood and always present antigens in response to infection.

Can someone please help?

It's B. Malaria is spread by vector.
It isin't a genetic or transmissible diseases lol.

A patient with tb can pass to his child if he sneeze but malaria is only transferred by mosquito itself..malaria as it is passed by vector anopheles mosquito, fetul blood is seperate from mother's blood so plasmodium will not be able to pass. :/
HIV/Aids would be most likely to be passed on due to the transfer of virus. breast feeding, blood transfusion or accidental mixing could cause it..fluids exchange can occur so there are more ways for this disease to be transferred
Sickle cell anemia is a well known genetic diseases.
Cholera spreads only through oral feecal root.If patient poops and don't wash there hands and feed baby with dirty hands etc cholera can spread directly as well
