Barriers

Barriers

Physical, chemical, and response mechanisms that protect the body from pathogens.

Hair

A protective layer that captures pathogens, protects orifices, and provides airborne protection.

Skin

An organ covering the body that prevents the external environment from entering through direct contact and fomite contact.

Cilia

Little hairs that line the digestive, reproductive, and respiratory tracts and work with mucous to waft it out of the body.

Mucous

A sticky, thick substance that catches pathogens entering the body and provides airborne and ingestion protection.

Cough

Clears the throat and upper digestive tract to provide ingestion protection.

Sneeze

Cleans the respiratory tract and provides airborne protection.

Diarrhoea

Flushes the digestive tract, provides ingestion protection, and leads to dehydration.

Urination

Flushes the excretory tract, filters the blood, removes harmful substances, and provides ingestion and inhalation protection.

Dehydration

Leads to less mucous, increasing the risk of illness.

Tears

Contain lysosomes that digest debris and pathogens and flush the eye cavity.

Vaginal discharge

Flushing and acidity destroy STIs and is very acidic (around pH 3).

Stomach acid

Creates an acidic environment that kills pathogens, provides ingestion protection, and its effectiveness is reduced by ulcer supplements.
