Cardiovascular system

coronary heart diease is blocking of the arteries that directly supply the heart muscle. Arteries carry oxygen rich blood, which all cells need to function. Without oxygen, muscle cells die. It is caused by the natural aging process, where the once elastic walls of the arteries harden and become less flexible. Smoking, diabetes, obesity and genetics also contribute to heart disease.

Stroke - A stroke is a brain attack. We have arteries and veins running through the brain. These vessels can either become occluded due to plaques which can break free from the walls of arteries and block the vessel.

Thrombosis
The heart is surrounded by three major coronary arteries that supply it with blood and oxygen. If a blood clot develops in one of these arteries, the blood supply to that area of the heart muscle will stop.

embolism A mass, such as an air bubble, a detached blood clot, that travels through the bloodstream and lodges so as to obstruct or occlude a blood vessel.

Varicose veins
Varicose veins are enlarged and distended veins. They can occur anywhere in the body, but are particularly common in the pelvis and legs. Weak or damaged valves in the veins can cause varicose veins

High blood pressure
The pressure within the blood vessels depends on how hard the heart pumps, and how much the arteries resist. Slight narrowing of the arteries may then increase the resistance to blood flow, increasing the blood pressure

Low blood pressure is the force that your blood puts on the walls of your arteries as it's pumped around your body by your heart. This is affected by the strength with which your heart pumps, and the size and flexibility of your arteries that carry the blood.

    Asthma Attack – An asthma attack is a sudden worsening of asthma symptoms caused by the tightening of muscles around the airways. During an asthma attack, the lining of the airways also become swollen or inflamed and thicker mucus, more than normal, is produced. All of these factors, cause symptoms of an asthma attack such as difficulty breathing, wheezing, coughing, shortness of breath and difficulty performing normal daily activities.…

    Coronary artery disease is the condition of the narrowing of the arteries that supply oxygen and blood to the myocardium (heart muscle). The narrowing is caused by a substance called plaque, which contains deposits of fat that cause blockages within the arteries. The blocked arteries then become hardened (atherosclerosis) and narrow, not allowing adequate…

    Blood pressured is measured by the end-systolic volume (the volume of blood in a ventricle at the end of contraction) and the end diastole volume (the volume of blood in the ventricle at end load or filling). The heat from the Water will also aid the body in becoming dehydrated this will cause the viscosity (the resistance of blood flow) of the blood to become higher, making it harder for it to flow through the blood stream imposing Venous return (the rate of blood flow back to the heart.) venous return normally limits Cardiac output (the amount of blood pumped out of a ventricle per beat). Cardiac output is calculated as the product of stroke volume (the volume of blood pumped from one ventricle of the heart with each beat) and heart rate (the number of times the heart beats per one…

    Athletes have a blood pressure of 123.7/80.2 torr, while non athletes have a blood pressure of 111.2/70.2 torr. This obviously relates to blood pressure which is the amount of force that blood pushes against the inside walls of blood vessels as it passes through and is initially produced by the contracting heart and is necessary to push blood along to all organs in the body. The fall in BP from 100 torr in the arterial system to 2 torr in the venous system is mainly explained by resistance to blood flow. The blood, after leaving the heart, passes into vessels of smaller and smaller diameter. This slows the flow. Also, there is the friction on the blood by the blood vessel walls. Both of these forces, are called peripheral resistance. Peripheral resistance can be increased if arteriole diameters are reduced as by the formation of fatty deposits on the walls of the blood vessel. Blood trying to squeeze through such a small diameter pushes harder against the walls of the blood vessel, increasing the BP. This can lead to high blood pressure, called hypertension. Risk factors for this condition are heredity, a diet high in fats, smoking, and lack of…

    The body is designed to protect itself. One of the keys to this protection is the blood's ability to clot. Every time a person is cut, scratched, or needs to heal from a wound, they should rejoice that their blood has the ability to clot and stop the bleeding. Sometimes, a blood vessel inside the body will be injured and the blood will clot inside the body. Other times, blood will pool in a vein due to improper blood circulation, and the stagnant blood will clot. Cracks in cholesterol plaques on the artery walls can also trigger clotting in the blood.…

    Angiotensinogen has an effect on the blood vessels including constricting the blood vessels which then increase the blood pressure. It also has an effect on the nerves, adrenal glands and kidneys. Angiotensinogen requires conrol. Renin is increased if blood pressure is decreased, sensed by the kidneys. More renin increase means an increase in the conversion of angiotensinogen to angiotensin I. This has to be then converted to angiotensin II by an enzyme which limits angiotensin metabolism.…

    The cardiac muscle of the heart wall depends on a constant flow of blood supply by the coronary arteries. Coronary arteries are blood vessels that arise from the base of the aorta and bring freshly oxygenated blood to the heart muscle. If this supply is restricted, then oxygen and nutrients can’t reach the muscles and the result could be a form of coronary artery disease (CAD). It can also be known as coronary heart diseases (CHD). This form of partial or complete block can be caused by fatty deposits, blood clots, or both. Overall, the extent of the symptoms of coronary artery disease depends on the location, severity, and how fast the disease will start from the limited blood supply.…
