general types, each with a different action against pathogens:
Name them

Answers

Answer:

The leukocytes of innate immunity can be, according to their functions, leukocytes with phagocytic activity and natural killer leukocytes or NK.

Explanation:

Innate immunity is a natural and non-specific immune response of an organism, which implies an immediate response but does not extend over time. The innate cellular response includes phagocytes and natural killer cells or NK.

- Phagocytes or leukocytes with phagocytic function can identify and eliminate foreign agents generally, without discriminating between the type of agent. Macrophages, dendritic cells and neutrophils belong to this cell group.

- NK cells are able to eliminate cells in the body infected by microorganisms, as these cells are not recognized as their own due to changes in their cellular markers. Tumoral and virus-infected cells can be eliminated by NK. Basophils, eosinophils and mast cells belong to this group of NK cells.

Metabolic syndrome is a group of risk factors that includes high cholesterol, high blood pressure, high blood sugar levels, and abdominal obesity. These risk factors are often caused by poor diet and lack of exercise. Traditionally, these risk factors affect only adults and not younger populations. However, current studies show that adolescents and teenagers are developing metabolic syndrome.

Answers

Explanation:

It is a fact that adolescents and teenagers are facing metabolic syndrome nowadays. Since they are all using social media the most, the truth about this type of syndrom could be spread more on the internet and especially Instagram so everyone can see it. In that way, the young population will see how many problems it can cause and they will be a little careful about that stuff.

It is good also if someone also shows them what is the minimum that everyone can do in due to help themselves and then if they are interested and motivated, they can discover how it would be if they look for themselves like they should, with their maximum.
