Stasis of urine in the bladder may promote bacterial growth, leading to local and ascending infection to the:

Choice A reason: Peristalsis is the process by which smooth muscle fibers in the walls of the ureters contract rhythmically to propel urine from the kidneys to the bladder. This coordinated movement involves a wave-like series of contractions and relaxations, ensuring that urine is efficiently transported along the ureters, even against gravity. Peristalsis is a crucial mechanism for maintaining the flow of urine and preventing backflow into the kidneys.

Choice B reason: Mass movement refers to strong, coordinated contractions in the colon that move fecal matter toward the rectum. This process is associated with the large intestine and is not involved in the movement of urine through the ureters.

Choice C reason: Segmental contractions are localized contractions in the intestines that help mix and propel intestinal contents. They are not the primary mechanism for moving urine through the ureters.

Choice D reason: Tetany refers to involuntary muscle spasms or contractions, usually caused by low calcium levels or other electrolyte imbalances. It is not a normal physiological process for propelling urine through the ureters.

Choice A reason: Risk factors for type 2 diabetes include hypertension, family history, and obesity. These factors increase the likelihood of developing type 2 diabetes. Hypertension, or high blood pressure, is often seen in individuals with type 2 diabetes due to the correlation between these conditions. A family history of diabetes indicates a genetic predisposition to the disease. Obesity, particularly central obesity (excess fat around the abdomen), is a significant risk factor as it contributes to insulin resistance, a key component in the pathophysiology of type 2 diabetes.

Choice B reason: The onset of type 2 diabetes is typically gradual, which means that it develops slowly over time. Many individuals may have prediabetes for years before their condition progresses to type 2 diabetes. This gradual onset can make it challenging to diagnose early, as symptoms may be mild or absent initially. Early detection through routine screening and awareness of risk factors is essential in managing and preventing the progression of the disease.

Choice C reason: Type 2 diabetes accounts for approximately 90-95% of all diabetes cases. It is the most common form of diabetes and is primarily characterized by insulin resistance and relative insulin deficiency. Unlike type 1 diabetes, where the body's immune system attacks and destroys insulin-producing cells, type 2 diabetes typically develops due to a combination of genetic and lifestyle factors, such as poor diet and lack of physical activity.

Choice D reason: Significant weight loss is not a typical sign of type 2 diabetes. Instead, it is more commonly associated with type 1 diabetes, where the body cannot produce insulin, leading to the breakdown of fat and muscle for energy. In type 2 diabetes, weight loss may occur if blood sugar levels are very high, but it is not a common initial symptom. More commonly, individuals with type 2 diabetes may experience symptoms such as increased thirst, frequent urination, and fatigue.
