Insulin is a hormone produced by the beta cells of the islets of Langerhans in the pancreas. Insulin plays a critical role in regulating blood glucose levels by facilitating the uptake of glucose into cells, particularly in muscle and adipose tissue. It also inhibits the production of glucose by the liver. When blood glucose levels rise after eating, insulin is released to help lower glucose levels back to a normal range. Insufficient insulin production or action leads to diabetes mellitus, characterized by hyperglycemia (high blood sugar).

Question # 59
The purpose of applying paste or jelly when running an EKG Is to reduce
The purpose of applying paste or jelly when running anEKG (Electrocardiogram)is toreduce skin resistance. This conductive gel ensures better conductivity between the skin and the electrodes, resulting in a clearer and more accurate recording of the heart's electrical activity. Without the gel, poor contact can lead to high resistance and artifacts in the EKG trace.
