True or False: Albumin plays a role in the immune response.

Albumin is primarily recognized for its role in maintaining oncotic pressure in the bloodstream and serving as a carrier protein for various substances, such as hormones, fatty acids, and drugs. While it does have some indirect involvement in immune responses—mostly through its capacity to bind small molecules and influence fluid distribution—its primary function is not directly linked to the immune system, and it does not act as an immunoglobulin or a component of the adaptive immune response.

The statement that albumin plays a role in the immune response is therefore false, making the correct response appropriate. The immune system relies more heavily on specialized proteins such as antibodies and various cytokines, rather than albumin, to effectively mediate immune responses and protect the body against pathogens. Thus, asserting that its function is not integral to the immune response is consistent with our understanding of albumin's role in the body.
