¶ … blood vessel resistance and heart function. In the paper, four peer reviewed journals are looked at to highlight any potential relationship between blood vessel resistance and the heart's functioning.
In normal functioning of the heart, there are critical factors that influence blood resistance. These factors include blood vessel's radius, blood viscosity and vessel length (Cinar, Demir, Pac, & Cinar, 1999). Of the three factors, vessel diameter is the most important in determining blood vessel resistance and heart functioning. Vessel changes due to contraction and relaxation of the vascular smooth muscle in the wall of the blood vessel directly influencing blood resistance which then affects heart functioning. In addition, small variations in vessel diameter leads to large changes in resistance which affect heart functioning.
Effect of Blood Vessel Radius on Blood Flow Rate
Increase or decrease in blood vessel radius can either increase or reduce blood flow rate to the heart. When blood vessels dilate, the flow of blood is increased due to a decrease in vascular resistance. Therefore, dilation of arterial blood vessels causes a decrease in blood pressure. The widening of blood vessels which bring changes in their radii thus takes a lot of blood into the...
Korotkoff Phase Should Be Used as the Endpoint for the Measurement of Diastolic Blood Pressure During Pregnancy Literature Selection and Identification Critical Appraisal of Selected Literature Five Korotkoff Phases Conducting System of Human Heart Two of the most common complicating problems seen during pregnancy are the appearance of gestational diabetes and of hypertension. Both of these conditions are more likely to occur during late pregnancy and both generally abate in the postpartum period. Nevertheless,
One's heart may appear enlarged in heart failure. The X-ray also may reveal whether ther e is any fluid buildup in the person's lungs. X-rays also sometimes show conditions other than heart failure that possibly cause the patient's signs and symptoms (Mayo Clinic Staff, 2009). Electrocardiogram (ECG): Through electrodes attached to the patient's skin, an ECG records the electrical activity of person's heart and records the impulses. These impulses, displayed
Congestive Heart Failure It is a fact that Congestive Heart Failure is an extremely frightening word and an equally frightening concept to comprehend, and when a loved one, or oneself has been diagnosed with this condition, it is quite natural to relapse into a state of depression or panic. However, it is not an untreatable disease, and with the correct and appropriate treatment methods, and with the right physician attending, the
Activity is another important concern for many individuals that have congestive heart failure. Some of them will be resentful of the fact that they are no longer are able to perform many of the activities that they once performed, and others will be so afraid to perform any type of activity at all that they will become sedentary, which can also be dangerous. All individuals, regardless of their medical condition,
The picture to the left depicts the various elements that are responsible for thermoregulation in human skin. The illustrations shows the various layers of skin along with the veins, arteries and capillaries of the circulatory system that assist in insuring that the thermoregulatory system works properly. The sweat glands are responsible for selectively removing materials from the blood the sweat glands then concentrates or alters these toxins, and secretes them
Coronary Heart Disease: Symptoms, Diagnosis, And Treatment Options Coronary Heart Disease Among the common diseases that affect the heart, coronary heart disease is the most common in the U.S., and is the leading cause of heart attacks among men and women. Coronary heart disease, in some quarters referred to as coronary artery disease (CAD), is the inability of blood vessels to supply the required amount of oxygen and blood to the heart
