One complete heart beat, combining the contraction (systole) and relaxation (diastole) phases, is known as the cardiac cycle. The cardiac cycle consists of two main phases: systole, where the heart muscle contracts to pump blood out of the chambers, and diastole, where the heart muscle relaxes to allow the chambers to fill with blood. This sequence ensures that oxygenated blood is circulated throughout the body and deoxygenated blood is sent to the lungs for oxygenation.

During an eye examination using the Snellen's eye chart, the patient shouldkeep both eyes open, but cover one of them.

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.

Aglucose tolerance test (GTT)is used to evaluate how well the body processes glucose, which is crucial for diagnosing conditions related to sugar metabolism, such as diabetes and insulin resistance. During the test, a patient consumes a glucose-rich beverage, and blood samples are taken at intervals to measure blood glucose levels. The primary purpose is to assess the body's ability to metabolize sugar.

Palpationis done byfeeling a part with the hand. It is a technique used by healthcare providers to examine the body through touch to assess the size, shape, firmness, or location of a structure.
