They break down the pathogens that enter the body
Explanation:
- Macrophages are the first line of defense .
- They engulf any pathogen that gets in their way in a process called phagocytosis
Phagocytosis
- When the macrophages ingest the pathogen ,the cell membrane surrounds the pathogen to form a vesicle known as a phagosome
- Later this phagosome is combined with a lysosome ,which is a vesicle containing digestive enzymes to form phagolysosome.
- The digest enzymes in the lysosomes breaks the pathogen down.

and elevated blood pressures are physiological symptoms of stress. When a
person is experiencing high levels of stress, bodily functions and chemical
processes within the body become imbalanced. Stress causes the heart to pump
extra and the brain produces high levels of chemicals to trigger a protective
response to stressors. People who experience chronic stress tend to develop
other diseases (e.g. heart failures, stroke) that may lead to death. In order
to manage stress a person must engage in breathing and relaxing exercises that
may return the body back to its homeostasis. </span></span></span>
