The male orgasm samer kareem 56,404 Views • 2 years ago

The fuel for the process leading to orgasm is testosterone, a hormone produced in steady supply by the testicles. The testicles also make millions of sperm each day, which mature and then are mixed with whitish, protein-rich fluids. These fluids nourish and support the sperm so they can live after ejaculation for a limited time. This mixture of fluid and sperm, known as semen, is what is moved through the urethra and out the penis during orgasm.

Hypertension Urgency
Hypertension Urgency samer kareem 3,081 Views • 2 years ago

Hypertensive emergencies encompass a spectrum of clinical presentations in which uncontrolled blood pressures lead to progressive or impending end-organ dysfunction. In these conditions, the BP should be lowered aggressively over minutes to hours. Neurologic end-organ damage due to uncontrolled BP may include hypertensive encephalopathy, cerebral vascular accident/cerebral infarction, subarachnoid hemorrhage, and/or intracranial hemorrhage.[1] Cardiovascular end-organ damage may include myocardial ischemia/infarction, acute left ventricular dysfunction, acute pulmonary edema, and/or aortic dissection. Other organ systems may also be affected by uncontrolled hypertension, which may lead to acute renal failure/insufficiency, retinopathy, eclampsia, or microangiopathic hemolytic anemia.[1] With the advent of antihypertensives, the incidence of hypertensive emergencies has declined from 7% to approximately 1% of patients with hypertension.[2] In addition, the 1-year survival rate associated with this condition has increased from only 20% (prior to 1950) to a survival rate of more than 90% with appropriate medical treatment

Calcium Channel Blockers
Calcium Channel Blockers samer kareem 1,501 Views • 2 years ago

Calcium channel blockers prevent calcium from entering cells of the heart and blood vessel walls, resulting in lower blood pressure. Calcium channel blockers, also called calcium antagonists, relax and widen blood vessels by affecting the muscle cells in the arterial walls. Some calcium channel blockers have the added benefit of slowing your heart rate, which can further reduce blood pressure, relieve chest pain (angina) and control an irregular heartbeat. Examples of calcium channel blockers Some calcium channel blockers are available in short-acting and long-acting forms. Short-acting medications work quickly, but their effects last only a few hours. Long-acting medications are slowly released to provide a longer lasting effect. Several calcium channel blockers are available. Which one is best for you depends on your health and the condition being treated. Examples of calcium channel blockers include: Amlodipine (Norvasc) Diltiazem (Cardizem, Tiazac, others) Felodipine Isradipine Nicardipine Nifedipine (Adalat CC, Afeditab CR, Procardia) Nisoldipine (Sular) Verapamil (Calan, Verelan) In some cases, your doctor might prescribe a calcium channel blocker with other high blood pressure medications or with cholesterol-lowering drugs such as statins.
