A common consequence of many cancer chemotherapy drugs is destruction of bone marrow cells. This leads to a decrease in the number of circulating erythrocytes and leukocytes, resulting in conditions called anemia and leukopenia, respectively. Predict the consequences of anemia and leukopenia, considering the function of these types of cells

Stopping bleeding in the human body requires different biological steps that are interdependent. What are these steps?

Blood clotting is a homeostatic response.   When clotting is poor, even a slight injury to a blood vessel may lead to severe blood loss. When clotting is excessive, small blood vessels in critical places in the body can become clogged leading to clots.  Excessive bleeding or excessive clotting both can be dangerous.   – Describe the main stages in the formation of a blood clot and evaluate the importance of specific factors example platelets, vitamin K, air and blood proteins     Injured tissue – exposure of endothelial cells Narrowing (constriction) of blood vessels Activity of platelets Activity of clotting factors

Type I diabetes is caused by destruction of the beta cells of the pancreas, the cells that produce insulin. In most cases, the beta cells are destroyed by an immune response. Both genetic and environmental factors are involved in triggering the immune response.   NOD mice develop a disease very much like Type I diabetes. (NOD mouse = non-obese, diabetic, mouse). If you transfer plasma from a NOD mouse to a normal mouse, the normal is not affected. If you transfer lymphocytes (WBCs white blood cells) from a NOD mouse, the normal mouse develops diabetes. The first people to figure this out found they had to transfer two types of WBC to transfer diabetes. After some experiments, they found that under the right conditions, they only had to transfer one type of cell to cause diabetes in the recipient.   B-1. Consider the one type of WBC that can cause diabetes by itself. Which type is it likely to be? (B cells) (helper T cells) (cytotoxic T cells) (either type of T cell) (any of these)…
