Question

The immune system of the child matures with age. An infant's immune system is incapable of producing immunoglobulins and white blood cells. Cell-mediated immunity decreases with an increase in age because older adults experience alterations in the structure and function of body parts. Young and middle-aged adults have refined defenses and immunity against infections. Breastfed infants receive antibodies through breast milk; these infants have greater immunity than infants who are bottle-fed.

a. true
b. false

Answer 1

The statement is true. As infants, their immune systems are not fully developed, and they rely on passive immunity through breast milk. Antibodies produced in the mother's body are passed on to the infant through breast milk.

Step-by-step explanation:

The statement is true.

As infants, their immune systems are not fully developed, and they rely on passive immunity through breast milk. Antibodies produced in the mother's body are passed on to the infant through breast milk, providing them with temporary protection against infections and diseases. This is an example of active immunity, where the infant receives antibodies that stimulate their own immune system to produce immunoglobulins and white blood cells. As the child grows and matures, their immune system becomes capable of producing these cells and their cell-mediated immunity increases.
