Clinical Anatomy For Dummies. The meninges are the coverings of the brain. They protect the brain by housing a fluid-filled space, and they function as a framework for blood vessels. The meninges have three layers: the dura mater, the arachnoid mater, and the pia mater. The arachnoid mater is attached to the pia mater by arachnoid trabeculae, which is a weblike matrix of connective tissue. The space between the two layers, the subarachnoid space, is filled with cerebrospinal fluid (CSF).
Potassium-sparing diuretics cause the kidneys to hold potassium in the body. When you are taking these medications you generally should not take potassium supplements because your potassium levels might rise too high. Treatments that combine thiazide diuretics (which cause potassium loss) and potassium-sparing diuretics can affect potassium levels unpredictably. If you are taking such a combination medication, do not take potassium except on the advice of your physician.
Thiazides are the only type of diuretic that dilates (widens) the blood vessels, which also helps to lower blood pressure. 2. Potassium-sparing diuretics are used to reduce the amount of water in the body. Unlike the other diuretic medicines, these medicines do not cause your body to lose potassium.3. Loop-acting diuretics cause the kidneys to increase the flow of urine.
