3. The __________ drain(s) lymph from the lower limbs, pelvis, kidneys, adrenal glands, and abdominal wall. a) Bronchomediastinal trunks b) Interstinal trunk c) Lumbar trunks d) Subclavian trunks e) Jugular trunks

4. Innate immunity is: a) Developed in response to a specific pathogen b) Responsible for the production of antibodies c) Always present to provide rapid responses against disease d) Used by the body to transport lipids
