Lymph nodes use white blood cells to fight infection, but they do not produce white blood cells.
Lymph nodes are the second line of defense against infection.
Lymph nodes are produced by the primary lymphoid tissues.
Explanation:
they filter out pathogens they mantain the population of mature lymphocytesThe secondary lymphoid organs are the lymph nodes and spleen, which keep the number of mature lymphocytes in check and filter out infections, hence option B is correct.
What is secondary lymphoid tissue?The thymus, where T-lymphocytes develop, and red bone marrow, which produces blood and immune cells, are the two main lymphoid organs.
Lymphocytes are also stimulated in secondary lymphoid tissues. Peyer's patches, tonsils, spleen, lymph nodes, and mucosa-associated lymphoid tissue are among them (MALT).
Numerous lymphocytes, a kind of white blood cell, are found in lymph nodes. They produce substances that stimulate other immune system components and aid in the battle against the illness. This is the reason why when you have an infection, your lymph nodes expand.
Therefore, the lymphocytes in your lymph nodes grow if you have an infection, hence option B is correct.

Making Informed Healthcare Decisions:
- A two- to three-sentence review of the health solutions you chose, and your reasoning for choosing them
- Use sites such as the Centers for Disease Control and Prevention (CDC) or Consumer Reports for product reviews, or consult a physician for more information. (Cite credible sources to back up your answer.)
- Use your research to list and review three health solutions for each health issue.
- Use your research to identify the most effective health solution for each health issue.
- Write summaries of the health solutions you chose.
Answer:
It states write 3 summaries of three things. I chose cancer, weight loss, and diebeties.
Explanation:
Summaries of the health solutions I chose.
Cancer: Why is it that only the very expensive places that you can travel to have everything down to a meal planned to assist you with dying or getting better? Shouldn't all medications and procedures be made available to anyone that needs it? Just because cancer treatments are a lot of money, some people have cancer but not the money. This needs to change.
Weight Loss: There are so many options available, yet the education on how to eat and live healthily is forgotten. If we would take the time to teach families how to eat healthily, help them with the grocery list, and provide classes to help them learn how to prepare these items in a healthy manner would be appropriate and beneficial.
Diabetes: All people do not have access to everything that they need and they often cannot afford the office visits, etc to include the medication and food prep that they need. This could cause their condition to get worse. There should be ways for people to get the medicine they need even if they can’t afford it.
Other Stuff: People are going to have to be taught how to make an appropriate decision based on their healthcare and their family's needs. We cannot continue to expect a young mother that is poor and does not have transportation and does not have the money to buy certain foods to be healthy and to make healthy meals for her family. We need to work on not making these young mothers feel guilty based on how to care for their children/families. Most of them are trying their best and our message to them is that they need to be responsible and give healthy choices to their children/families. Classes need to be made available online and at certain places in the community so that the solutions to the health problems are attainable for everyone. People need to receive incentives for attending these types of classes and they may even need a computer or transportation.
