Heart valve

The uptake of oxygen into muscles is what facilitates muscle contraction. Oxygen that is obtained through breathing by the lungs is transported to the rest of the body, as well as the heart by means of haemoglobin. The rate of liberation of oxygen from haemoglobin has an effect on the quantity of oxygen available in the muscles for a muscle contraction to ensue. The higher the oxygen concentration in the muscle the greater the force of muscle contraction. Temperature has an effect on the…

tissue and neoplastic disorders can all effect cardiac function. Vasodilators, beta blockers and calcium channel blockers are associated with prior heart disease and cardiogenic risk factors such as hypertension. Oedema alone does not signify heart disease as it has many causes. In order to improve the diagnostic power of oedema as a sign of heart failure vasodilating drugs should be excluded as they can lead to oedema. Bilateral, pitting ankle oedema with no pain or redness in the absence of…

They needed close ventillatory and cardiovascular monitoring and support. Medical complications as chest infections, ischemic heart attacks and uncontrolled diabetes were recorded. Seven wound infections were encountered that were successfully treated in six cases by sensitive antibiotics after obtaining culture and sensitivity and repeated daily dressings while in one patient…

deaths in a group of people or from a disease over a specific time period, usually one year. Examples of common causes of deaths are heart disease, strokes and some cancer. Australia’s death rate is on the decline, currently 79 per 100,000. This is still high because of our growing and aging population. In Australia overall, the main causes of death are cardiovascular (heart and blood vessel) diseases, cancers and respiratory…

Footstrike Hemolysis Footstrike hemolysis happens when red blood cells in the foot break down faster than usual. This is usually due to repeated contact between the foot and the ground. This condition often happens to long-distance runners. It can also happen to other athletes, including dancers and hikers. This condition may also be called march hemoglobinuria. This condition may cause part of the red blood cells (hemoglobin) to appear in the urine, making the urine red (hematuria). In most…

(or other exertion); lightheadedness; hot flashes--are typical of what people experience just prior to passing out. These are also called "pre-syncopal" symptoms. You mention the Holter Monitor had showed a abnormally fast heart beat (tachycardia). How fast was it? Did the heart rate slow down when you started taking Propranolol? The "Neurocardiogenic Syncope Syndrome" should not continue after the lone episode of food poisoning. Once the acute illness is over, and once you re-hydrate…

Section A The skin is the largest organ of the human body. It's main function is to protect the internal organs, muscles, nerves, and blood vessels (Cancer Council Victoria, 2016). The skin is made up of three main layers - the epidermis, the dermis and the fat layer. The layer of fat insulates the body and keeps in warm from changing outside temperatures. The next layer is the dermis, which contains fat, collagen and elastin fibres which provide strength and flexibility to the skin. Blood…

Polycythemia Vera Polycythemia vera (PV) is a form of blood cancer. Another name for this type of disease is myeloproliferative disease. This means your bone marrow produces too many red blood cells. Bone marrow is the spongy center of long bones where blood cells are produced. If you have PV, your bone marrow may also make too many white blood cells and clotting cells (platelets). Almost all people with PV have an abnormal gene (genetic mutation) that causes changes in the way the bone…

Oxybutynin Chemical structure Mode of action and pharmacology Oxybutynin is an antimuscarinic, antispasmodic medicine that is used to relieve urinary symptoms caused by an overactive bladder. An over active bladder is caused by involuntary contractions of the detrusor muscle surrounding the bladder causing it to empty unnecessarily. The detrusor muscle helps control normal working functions by relaxing and contracting as the bladder fills and empties. Symptoms include…

The arteries carry oxygen and blood from the heart which is me to the rest of the body, Then the veins return the blood to me after the oxygen has been used. I have worked with Mr. Lungs and Mrs. Brain for over 12 years now…
