Question

How does human skin act as a physical barrier against bacterial attacks?

Answer 1

• The skin is your body’s largest organ and its most important barrier against infections.
• It’s your first line of defence in protecting internal tissues from harmful germs.
• When there’s a break in your skin, it’s easier for germs to get into your body and cause infection.
• Mucous membranes, which form the moist, pink lining layer of the mouth, throat, nose, eyelids, urethra, vagina, and digestive system, also act as a partial barrier against infection.
• These membranes normally help protect us from germs in the air we breathe, our environment, and in our food and drink.
• Hence, human skin act as a physical barrier against bacterial attacks.
