Pathophysiology Infection and inflammation of the kidneys is called pyelonephritis. Pyelonephritis is a type of urinary tract infection. E. coli is the most common microbe that causes pyelonephritis. It usually begins in the urethra or bladder and travels to the kidneys. There is a chance of it spreading to the calyces and medullary tissues such as the tubules of the nephrons. If not treated the glomeruli will also be infected and inflamed. (Bullock & Hales 2013). There is both acute pyelonephritis

Portal Hypertension Abdominal Ultrasound Portal hypertension is a pathologic condition characterized by an excessive increase in the pressure within the portal vein or one of its branches. Typical portal vein pressure is 5 to 10 millimeters of mercury (abbreviated mmHg). When the pressure exceeds 5 mmHg above inferior vena cava pressure‚ it is characterized as portal hypertension. The portal vein carries nutrient rich blood from the digestive system to the liver. Normally‚ the veins come from

Exam Case Scenario Pathophysiology of Asthma Asthma is a chronic lung disease characterized by episodes in which the bronchioles constrict due to oversensitivity. In asthma‚ the airways (bronchioles) constrict making it difficult to get air in or out of the lungs. Breathlessness is the main symptom. The bronchi and bronchioles become inflamed and constricted. Asthmatics usually react to triggers. Triggers are substances and situations that would not normally trouble an asthma free person. Asthma

The more pressure the blood exerts on the artery walls‚ the higher
