What are Some Clinical Conditions Involving Smooth Muscle?

Several clinical conditions can affect smooth muscle function. For instance, disorders like asthma involve the constriction of smooth muscle in the airways, making breathing difficult. Hypertension often involves the excessive contraction of smooth muscle in blood vessels, leading to increased blood pressure. Gastrointestinal disorders such as irritable bowel syndrome can affect the smooth muscle contractions in the intestines, leading to symptoms like pain and irregular bowel movements.
