Answer:
The correct answer is "False".
Step-by-step explanation:
The lymph nodes are small structures that act as immune defense when an infection takes place in the human body. It is false to state that when someone is sick lymph nodes swell with extra erythrocytes, because lymph nodes swell with leukocytes not with erythrocytes. Lymph nodes filter lymph to identify the pathogens during an infection, if a pathogen is identify the nodes produce leukocytes: B cells and T cells that attack the pathogens via the immune system.
