**Quiz: Understanding Lymphocytes and the Immune System****Question: Which of the following statements are accurate?**- [ ] T cells, B cells, and Natural killer cells are lymphocytes.- [ ] Once activated, B cells can make clones. Some of these clones are called 'memory' cells and will live for years (decades, even) within the body.- [ ] If you remove the thymus of a baby, you will likely greatly reduce the ability to form mature T cells.- [ ] T and B cells are considered part of the adaptive immune system.- [ ] Antibodies and immunoglobulins are the same thing.- [ ] None of the answers are correct.**Instructions:** Select all statements that are accurate. **Quiz: Which of the following are correct?**- [ ] None of the statements are correct- [ ] Lack of iodine in one's diet might cause a disruption in thyroid hormone levels.- [ ] As you are under stress while taking this exam, it is possible that the adrenal glands are promoting the synthesis of glucose from non-carbohydrate sources. The steroid hormone known as cortisol would help the body do this.- [ ] If a person loses too much water in their urine in a short period of time, they will likely die from dehydration. The posterior pituitary hormone, ADH, acts to conserve water in the body.- [ ] Low levels of TSH might be the cause of hypothyroidism in a patient.- [ ] If I remove a patient’s adrenal gland, it is likely that the levels of ACTH would increase.

According to guidelines we have to answer the first question only. so please kindly post the remaining questions separately. Thank you Immune system is system which helps our body to fight against the foreign substances which will cause harm to our body. The cells which helps in the immunological processes are called immune cells. Immune system or immune response consists of 2 arms, one arm indicate non specific innate immunity and other arm indicates specific acquired immunity Different types of immune cells are lymphocytes which contains T- cells, B cells and Nk cells, neutrophils and macrophages. so, statement 1 is correct. B cells are under clonal expansion produce similar b cells in large number against a particular antigen and some of these clones can live longer than decades in case if the same antigen comes again it will kill the antigen. So, the statement 2 is also correct. Thymus is a lymphoid gland in which t cells mature, if the gland is removed in the children in early age the t cells wont mature. So, the statement 3 is also true T and B cells are considered part of the adaptive immune system and antibodies and immunoglobulins are same things. Statement 4 and 5 are true.
