The passage of IgG antibodies from mother to fetus illustrates passive immunity.
- Antibodies produced outside the body can protect a person from contracting a disease, or they can give passive immunity.
- Because antibodies are not regenerated as frequently as they would be in a person with a functioning immune system, passive immunity is typically transient.
- Immunity that is transferred from mother to kid is known as maternal passive immunity or natural passive immunity.
- Antibodies are transferred to the unborn child by the placenta while they are still in the womb and can offer protection against the corresponding infections in the weeks and months after delivery.
- An infant's passive immunity to disease is maintained after birth due to antibodies contained in breast milk, particularly in colostrum, the protein-rich milk produced in the first few days after birth.
- The importance of maternal passive immunity for safeguarding infants until their own immune system is mature enough to protect them.

The Teeth of Herbivores, Carnivores and Omnivores For instance, herbivores, because they are plant eaters, have strong and flat molars that are made for grinding leaves and small or non-existent canine teeth.
Carnivores, the meat eaters of the animal world, have very defined canine teeth for tearing at meat, combined with a sometimes limited number of molars.
Omnivores, because they eat both meat and plants, have a combination of sharp front teeth and molars for grinding.
