Immune System Basics

• Definition of Immunity: The state of being immune to a disease, meaning the body's ability to fight or protect against pathogens.

• Role of the Body: The body protects itself from illnesses through a response to exposure to pathogens.

Importance of Antibodies

• What are Antibodies?: Specialized proteins produced by the immune system in response to exposure to antigens (foreign substances).

• Production of Antibodies: After exposure to pathogens, the body builds antibodies to provide defense against future infections.

Immunity in Newborns

• Breastfeeding and Immunity: Essential for newborns to receive mother's milk right away after birth for immunity boost.

• Colostrum: The first breast milk, thick and yellowish, rich in antibodies and vital nutrients.

  • Importance for Newborn: Provides crucial protection and nutrition as the infant’s immune system is still developing.

Transition to Artificial Milk

• Artificial Milk: Contains nutrients and added antibodies, important for babies unable to breastfeed.
