Q

Pleura

A

A tough, protective double membrane around the lungs and inside the chest cavity

A

a noncellular entity that consists of a nucleic acid core (DNA/RNA) surrounded by a protein coat

42
Q

Immune system

A

a system that protects the body from disease-causing agents known as pathogens by responding to substances on the surfaces of agents that body perceives as foreign
