What type of immunity does the foetus receive from its mother during pregnancy?

Step-by-step solution

The foetus receives some antibodies from its mother through the placenta during pregnancy. These are an example of passive immunity. Colostrum is the yellowish fluid secreted by the mother during the initial days of lactation.
