Answer 1

Answer:

1)B 2)C 3)D E 4)E 5)A

Explanation:

Inflammation is the body defence system against various pathogens and include various components such as Immune cells and blood vessels. Inflammation occurs in a sequence of events.

• when a pathogen enters the cells macrophages produce the first response by phagocytizing the foreign body.
• The blood vessels dilated so more blood cells, oxygen and nutrients could reach at the site of pathogen and fight against it.
• Foreign pathogen is captured at that place so it can't mobilize to other part of the body.
• The more fighting cells are directioned at the site of infection
• The recruited phagocytic cells phagocytize the invaders pathogen and starts its degradation.
