It: Contains nerve receptors that allow you to feel touch, pain, and pressure Helps control fluid and electrolyte balance Helps control your body temperature Protects you from the environment Although skin has many layers, it can generally be divided into three main parts: The outer part (epidermis) contains skin cells, pigment, and proteins. The middle part (dermis) contains blood vessels, nerves, hair follicles, and oil glands. The dermis provides nutrients to the epidermis. The inner layer under the dermis (the subcutaneous layer) contains sweat glands, some hair follicles, blood vessels, and fat.

Fainting
Fainting samer kareem 1,439 Views • 3 years ago

Fainting occurs when the blood supply to your brain is momentarily inadequate, causing you to lose consciousness. This loss of consciousness is usually brief. Fainting can have no medical significance, or the cause can be a serious disorder. Therefore, treat loss of consciousness as a medical emergency until the signs and symptoms are relieved and the cause is known. Discuss recurrent fainting spells with your doctor. If you feel faint Lie down or sit down. To reduce the chance of fainting again, don't get up too quickly. Place your head between your knees if you sit down. If someone else faints Position the person on his or her back. If the person is breathing, restore blood flow to the brain by raising the person's legs above heart level — about 12 inches (30 centimeters) — if possible. Loosen belts, collars or other constrictive clothing. To reduce the chance of fainting again, don't get the person up too quickly. If the person doesn't regain consciousness within one minute, call 911 or your local emergency number. Check the person's airway to be sure it's clear. Watch for vomiting. Check for signs of circulation (breathing, coughing or movement). If absent, begin CPR. Call 911 or your local emergency number. Continue CPR until help arrives or the person responds and begins to breathe.

Mitral Valve Regurgitation Treatment
Mitral Valve Regurgitation Treatment samer kareem 1,287 Views • 3 years ago

A leaking mitral valve allows blood to flow in two directions during the contraction. Some blood flows from the ventricle through the aortic valve – as it should – and some blood flows back into the atrium. A leaking (or regurgitant) aortic valve allows blood to flow in two directions. Oxygen-rich blood either flows out through the aorta to the body – as it should – or it flows backwards from the aorta into the left ventricle when the ventricle relaxes. Leaking valves can cause the heart to work harder to pump the same amount of blood.

Laparoscopic Liver Surgery
Laparoscopic Liver Surgery samer kareem 4,277 Views • 3 years ago

The most frequent incision utilized to open the abdomen for liver surgery is called a chevron incision. In this incision a cut is made on the abdomen below the rib cage. The cut starts under the armpit below the ribs on the right side of the abdomen and continues all the way across the abdomen to the opposite arm pit thereby the whole width of the abdomen is cut to provide access to the liver. The average length of the incision is approximately 24 to 30 inches. This is one of the longest incisions is utilized in abdominal surgery. The incision is frequently associated with significant discomfort after the surgery and in some patients the discomfort can continue for many months, particularly when some of the nerves in the abdominal wall have been cut during the surgery. Laparoscopic surgery provides advantages over open surgery for the liver since the chevron incision is completely avoided and the surgery is performed through tiny incisions. As a consequence the duration of stay in hospital, the amount and duration of post operative discomfort, and the length of recovery is much shorter after the laparoscopic procedure compared to open surgery

Dizziness
Dizziness samer kareem 12,501 Views • 3 years ago

Dizziness is a word that is often used to describe two different feelings. It is important to know exactly what you mean when you say "I feel dizzy," because it can help you and your doctor narrow down the list of possible problems. Lightheadedness is a feeling that you are about to faint or "pass out." Although you may feel dizzy, you do not feel as though you or your surroundings are moving. Lightheadedness often goes away or improves when you lie down. If lightheadedness gets worse, it can lead to a feeling of almost fainting or a fainting spell (syncope). You may sometimes feel nauseated or vomit when you are lightheaded. Vertigo is a feeling that you or your surroundings are moving when there is no actual movement. You may feel as though you are off balance, spinning, whirling, falling, or tilting. When you have severe vertigo, you may feel very nauseated or vomit. You may have trouble walking or standing, and you may lose your balance and fall.
