What are the advantages of physical barriers in biology?
Biological barriers are factors that prevent species migration, interbreeding, or free movement. What determines the barrier depends on the species and it's method of movement. For some species biological barriers are physical like bodies of water, mountains, or deserts.
What happens to the bacteria we breathe in does it reach our bloodstream like inhaled nicotine and drugs do?
No. Bacteria have to penetrate our physical barriers. This means our skin (in a cut or wound) or the sticky stuff called mucous found in all body cavities that have an outside outlet. Also found here are chemicals that are antibiotic. These are the respiratory tract, the digestive tract, urinary tract and the reproductive tract. The respiratory tract also has millions of tiny hairs (cilia) that move the mucous up to the throat where it all is swallowed. Very little can live in the stomach which has acid that can burn a hole in a rug. People with COPD have destroyed these hairs and are at risk of respiratory damage. As far as drugs, those chemicals are much smaller than bacteria. Now, viruses can get to the blood stream (remember the cold virus).
What defends you from disease?
Physical barriers like skin and mucus membrane protects body from invasion of microorganisms. If they happen to cross these barriers, then 'innate immunity' of body kills the bacteria. If they happen to be pathogenic bacteria, then white blood cells go there and engulf them. They are helped by 'humeral' immunity of body. Thensubsequently immunity comes into action by 2 weeks to defend further attack by the same organism.

What are the 3 main barriers of defense of the body?
there are 5 ways which include: eyes - secretes tears which contain an antiseptic blood - contains platelets to clot blood and white blood cells to destroy bacteria stomach - contains hydrochloric acid which kills bacteria lungs - lined with small hairs (cilias cells) to trap dust hope it helps lol xx

how to identify social and physical barriers that may prevent equality and inclusion?
To identify social and physical barriers that prevent equality and inclusion, you can conduct a thorough assessment of the physical environment and social interactions to look for obstacles such as inaccessible buildings, discriminatory policies, lack of representation or diversity, and social norms that perpetuate exclusion. Additionally, consulting with marginalized groups and individuals who have faced barriers can provide valuable insights into the challenges they encounter in accessing equality and inclusion. Engaging in dialogue and awareness-building activities can also help uncover hidden barriers that may not be immediately apparent.
