Our bodies have many natural defences. Our main internal defence would be our immune system which helps combat bacterial and viral diseases. Our main external defence would be our skin which protects our body and prevents pathogens and microbes from entering our bodies. Hope This Helps :D

A white blood cell produces anti bodies to fight pathogens.
The epiglottis closes the airway when we swallow. You can see part of it hanging down in the back of the mouth.
The four main lines of defense against invading organisms in our bodies are: Physical Barriers: The skin and mucous membranes serve as the first line of defense, preventing pathogens from entering the body. Innate Immune Response: This includes non-specific immune responses such as inflammation and the activity of phagocytic cells that attack and destroy pathogens. Adaptive Immune Response: This involves the activation of lymphocytes (B cells and T cells) that specifically target and remember pathogens for more effective responses in the future. Microbiome: The beneficial microorganisms that inhabit our bodies help prevent the colonization of harmful pathogens by competing for resources and space.
the body's second line of defense against pathogens is the B cells.

Platelets.
We can't walk through walls because the atoms and molecules in our bodies are tightly packed together, creating a barrier that prevents us from passing through solid objects.

Yes. Anything that comes into our bodies MAY contain pathogens.
