Blood pressure is the pressure exerted by the blood on the walls of the blood vessels. Unless indicated otherwise, blood pressure is understood to mean arterial blood pressure, i.e., the pressure in the large arteries, such as the brachial artery (in the arm). The pressure of the blood in other vessels is lower than the arterial pressure. The peak pressure in the arteries during the cardiac cycle is the systolic pressure, and the lowest pressure (at the resting phase of the cardiac cycle) is the diastolic pressure ...

Blood pressure - Effects of high blood pressure. See main page Hypertension Blood pressure exceeding normal values is called arterial hypertension. It itself is only rarely an acute problem; see hypertensive crisis. But because of its long-term indirect effects (and also as an indicator of other problems) it is a serious worry to physicians diagnosing it. Any level of blood pressure puts mechanical stress on the arterial walls. This leads to unhealthy tissue growth (atheroma) that develops within the walls of arteries. The higher the pressure, the more stress that ...

The word "biofeedback" was coined in the late 1969 to describe laboratory procedures that trained research subjects to alter brain activity, blood pressure, muscle tension, heart rate and other bodily functions that are not normally controlled voluntarily. Biofeedback is a training technique in which people are taught to improve their health and performance by using signals from their own bodies.

Arteries are muscular vessels that carry blood away from the heart to the tissues and organs of the body (The vessels which return blood to the heart are veins). The circulatory system is extremely important in sustaining life. Its proper functioning is responsible for the delivery of oxygen and nutrients to all cells, as well as the removal of carbon dioxide, waste products, maintenance of optimum pH, and the mobility of the elements, proteins and cells, of the immune system. In First World countries the two leading causes of ...

An alveolus (plural:alveoli), is an anatomical structure that has the form of a hollow cavity. In the lung, the pulmonary alveoli are spherical outcroppings of the respiratory bronchioles and are the primary sites of gas exchange with the blood.

Hypertension or high blood pressure is a medical condition where the blood pressure is chronically elevated. While it is formally called arterial hypertension, the word "hypertension" without a qualifier usually refers to arterial hypertension.

A vasoconstrictor is any substance that acts to constrict blood vessels, i.e. make the lumen narrow, or vasoconstriction. Many vasoconstrictors act on specific receptors, such as vasopressin receptors or adrenoreceptors. Vasoconstrictors are also used clinically to increase blood pressure or to reduce local blood flow.

Cardiac cycle is the term used to describe the sequence of events that occur as a heart works to pump blood through the body. Every single 'beat' of the heart involves three major stages: atrial systole, ventricular systole and complete cardiac diastole. The term systole is synonymous with contraction of a muscle. Electrical systole is the electrical activity that stimulates the myocardium of the chambers of the heart to make them contract. This is soon followed by Mechanical systole, which is the mechanical contraction of the heart. The term dia ...

An arteriole is a blood vessel that extends and branches out from an artery and leads to capillaries. Arterioles have thick muscular walls and are the primary site of vascular resistance. The mean blood pressure in the arteries supplying the body is a result of the interaction between the cardiac output (the volume of blood the heart is pumping per minute) and the vascular resistance, usually termed total peripher ...

A vasodilator is a substance that causes blood vessels in the body to become wider by relaxing the smooth muscle in the vessel wall, or vasodilation. This will reduce blood pressure (since there is more room for the blood) and might allow blood to flow around a clot. Several vasodilators are used as drugs. Vasomotor refers to the muscles and nerves controlling the process of vasodilation. Natural vasodilators and drugs that exploit them: Adenosine Adenocard - this is primarily used as ...

Baroreceptors (or baroceptors) in the human body detect the pressure of blood flowing though them, and can send messages to the central nervous system to increase or decrease total peripheral resistance and cardiac output. Baroreceptors can be divided into two categories, high pressure arterial baroreceptors and low pressure baroreceptors (also known as cardiopulmonary receptors). Baroreceptor - Arterial Baroreceptors. There are baroreceptors present in the arch of the aorta, an ...

Carotid Sinus Syncope is a form of syncope associated with external pressure being applied to the carotid sinus. It is commonly subdivided into cardioinhibitory (heart rate affected) and baroreceptor(blood pressure affected), which have different treatments, although often can be both cardioinhibitory and baroreceptor (mixed) type. It may occur on just turning the head in some people. Other related archivescarotid sinus, syncope

Oligomeric proanthocyanidins or OPCs are a class of flavonoid complexes found in grape seeds and skin, that act as antioxidants (free radical scavengers) in the human body. Thus, OPCs may help protect against the effects of internal and environmental stresses (that is, cigarette smoking, pollution, and supporting normal body metabolic processes). The effects are; depressing blood fat, emolliating blood vessels, lowering blood pressure, preventing blood vessel scleroses, dropping blood visc ...

Perinatal asphyxia is the medical condition resulting from deprivation of oxygen (hypoxia) to a newborn infant long enough to cause apparent harm. It results most commonly from a drop in maternal blood pressure or interference during delivery with blood flow to the infant's brain. This can occur due to inadequate circulation or perfusion, impaired respiratory effort, or inadequate ventilation. Perinatal asphyxia ha ...

Antihypertensives are a class of drugs that are used in medicine and pharmacology to treat hypertension. There are many classes of antihypertensives, which—by varying means—act by lowering blood pressure. Evidence suggests that reduction of the blood pressure by 5-6 mmHg can decrease the risk of stroke by 40%, of coronary heart disease by 15-20%, and reduces the likelihood of dementia, heart failure, and mortality from vascular disease. Which type of medication to use initially for hypertension has been the subject of sever ...

Cor pulmonale is a medical term used to describe a failure of the right side of the heart. It is caused by prolonged high blood pressure in the right ventricle of the heart, which in turn is most often caused by pulmonary hypertension - prolonged high blood pressure in the arteries or veins of the lungs. People with heart disease, or lung diseases such as cystic fibrosis, are at greater risk. Cor pulmonale - Pathophysiology.
