Answer:
Cell-mediated immunity develops through a network of interactions that results in defense against microorganisms that survive within phagocytes or other cells. The response is initiated by the recognition of intracellular microorganism antigen by T cells through the histocompatibility complex. In the CD8 response, only the target cell carrying the class I associated antigen can be lysed or induced to apoptosis. In another mechanism of the cellular response, CD4 + Th1 T cells activate, for example, cytokine-infected macrophages such as IFN. When a pathogen resists the effects of activated macrophages, chronic infection may develop.
The hormonal immunity response leads to the destruction of extracellular microorganisms and prevents or decreases the spread of intracellular cells by neutralizing, opsonizing and activating the complement system.
Answer: Insulin is a hormone, which is secreted by the pancreas to regulate the sugar levels in the bloodstream.
Explanation:
Insulin is a protein hormone if take orally, will get digested in the digestive tract, it will not be able to affect the target site of action.
Insulin gets denatured in the digestive tract. Thus it will not be able to control the blood sugar levels.
Nancy has taken the insulin dose orally, the insulin will get denatured in the digestive system, it will not function and Nancy will remain hyperglycemic after the consumption.
