The Cardiovascular System Explained

Wednesday 18th October 2006: The cardiovascular system, also called the circulatory system , consists of the heart and a closed system of vessels – the arteries, veins, and capillaries. The heart is the muscular device that pumps the blood around the circuit of vessels.

The cardiovascular system has some characteristics that make it a unique and complex hydraulic system, such as the fact that it is a closed circle, the fact that it is elastic and the fact that it is filled with liquid at a positive mean pressure ("mean cardiovascular pressure"), which exists independent of the pumping action of the heart. The heart fills passively, rather than by actively sucking, and the flow from it is intermittent, while the flow to it is continuous.

The most important functions of the system are to maintain homeostasis and a favorable cellular environment. These functions depend on the continuous and controlled flow of blood through the thousands of miles of capillaries that reach every c…

Diagnosis of Heart Disease

Wednesday 18th October 2006: Diagnosis of heart disease is based on a series of tests; however, the doctor first assesses how well your heart is functioning by standard and simple procedures, such as listening to your heart, taking your heart rate and your blood pressure.

Heart rate, rhythm and regularity are assessed by checking pulse. The heart rate is the amount of times the heart beats in one minute. The heart sounds, made by the closing and opening of the valves, are listened with a stethoscope, and thus, the heart’s rate and rhythm can be evaluated. Blood pressure , the pressure exerted in the arteries by the blood as it is pumped by the heart, is recorded as two measurements: the systolic blood pressure - the pressure in the arteries during the period of the heart's contraction (the upper number), and the diastolic blood pressure - pressure in the arteries when the heart is relaxed, between heartbeats (the lower number). The normal blood pressure for a healthy adult during relaxation is less than or …

Treatment of Heart Disease

Wednesday 18th October 2006: Treatment for heart disease depends upon a series of factors. However, no matter what medical treatment you receive, lifestyle changes—including quitting smoking , following a heart-healthy diet, and exercising —are critical to managing heart disease. If medicine for the treatment or prevention of heart disease was prescribed to you, there are some general guidelines you should follow, such as: knowing the names, dosages and side effects of your medications and how they work. (keeping a list of your medications with you is a good idea); taking your medications as scheduled, at the same time every day; keeping a medicine calendar; not decreasing your medication dosage to save money; not taking any over-the-counter drugs or herbal therapies unless you ask your doctor first, as some drugs, such as antacids, salt substitutes, antihistamines or nonsteroidal anti-inflammatory agents can worsen heart failure symptoms; before any surgery, telling the doctor or what medications you are taki…
