Which barries the bacteria must overcome when entering the body?

Answer 1

The bacteria or any foreign particel to enter the human body have to cross many barriers and they are classified as line of defence

Skin is the first line of defence and it work as physical barrier for all the microbes and particle. Skin has many secreatory products which kill the bacteria also.

Then there comes some internal barriers like mouth which secreate cell disolving enzymes, eyes which secreat lacrymal secreations which act on bacteria to destroy it in stomach low pH and many bile salts are responsible for the prevention of bacteria to attack. These all comes under non-specific defence mechanism

Then there comes second and third i.e. last line of defence which is cell midiated and are done my immune organs and tissue like lymphnodes, spleen etc. and the cell are basophill eosinophill, neutrophill, Natural killer cells granulocytes like macrophages etc.

Answer 3

The barriers that bacteria has to overcome to enter the body is the skin barrier, the oral-cavity barrier, the digestive track barrier, and the respiratory tract barrier. The barriers help keep the bad bacteria out the body or flush it to an area that it will be ejected from body.

Answer 4

The bacteria has to overcome many barriers including:

The skin-it is a layer of protection to prevent things like bacteria coming into the body.

The mouth-The mouth kills bacteria. It will secreate cell disolving enzymes.

The antibodies-the antibodies will fight bacteria and microbes in the body as they help the white blood cell.

Answer 5

Bacteria must overcome physical barriers, such as the epithelial lining of the skin and mucous membranes, as well as immune defenses like antimicrobial peptides and phagocytic cells, to successfully enter the body and cause infection. Additionally, the body's normal microbiota can also compete with invading bacteria for resources and space.

Answer 6

It has to overcome the antibodies that kill it

Answer 7

The stratum corneum is what helps prevent bacteria fro coming in the body. This is what keeps people from been sick all the time.

Answer 8

Antibodies
