Sacred Heart

blood on the walls of blood vessels, it is controlled by a negative feedback system where heart rate and blood volume need to be altered in order to control the pressure. Local negative feedback systems and heart rate is regulated but the cardiovascular centre which also in turn controls neural and hormonal mechanisms. Neurons regulate heart rate and contractility and some neurons inhibit, stimulate or control heart rate by causing constriction which also controls the blood pressure. The…

The left side of the heart receives oxygenated blood from the lungs and pumps it to the cells and tissues to the body. The blood then returns to the right side of the body this is called systemic circuit. From the heart blood flows through large muscular arteries, then into smaller and smaller arteries, then arterioles and finally to the capillaries. It’s in the capillaries where the diffusion process takes place to exchange molecules of oxygen and nutrients for carbon dioxide of nearby cells,…

A polygraph is a common instrument of measurement to calculate and document physiological aspects such as respiration rate, electrodermal activity, and heart rate. The relevant uses of measuring respiration rate as well as heart rate are quite common in a wide variety of applications. However, electrodermal activity and the galvanic skin response are not commonly measured things in places such as the medical field, or education. Electrodermal activity (EDA) refers to the variation of the…

The supraspinatus is one of the four muscles that make up the rotator cuff in the shoulder. The body of the tendon lies along the supraspinous fossa of the scapula and attaches laterally to the humeral head. Its purpose is to withstand the inferior gravitational exertions set over the shoulder joint due to the downward pull of the weight of the upper limb. Not only that, but the supraspinatus also helps the shoulder joint stay in place. The supraspinatus muscle is primarily used for abduction.…

The skeletal system is essential to the working of the human body. It provides protection and aids with movement, also. Approximately 20% of the human body’s mass is attributed to the skeletal system. This system is mostly comprised of bones, but there are other critical elements included as well. These elements are ligaments and cartilage. The human skeletal system is divided into two parts; the axial and appendicular skeletons. The axial skeleton is further divided, from superior to inferior…

examination and wall stand selected. The DR central ray (CR) was horizontal and perpendicular to the wall stand detector with a focus film distance (FFD) of 180cm (Sloane et al, 2010). An FFD of 180 cm is recommended as it reduces the magnification of the heart, and reduces the radiation dose to the patient (Campeau and Fleitz, 2010). A focused grid is inserted into the moving grid mechanism of the wall stand and the automatic exposure chambers (AEC). The moving secondary grid absorbs maximum…

The resonatory system includes the nasal cavity and soft palate and portions of the anatomically defined respiratory and digestive systems. (Seikel, King, & Drumright, 2010). One disorder that may affect a person’s ability to use the resonatory system to produce sufficient speech is velopharyngeal insufficiency, or VPI. This is a disorder which results in the improper closure of the velopharyngeal sphincter (soft palate muscle in the mouth) during speech, allowing air to escape through the nose…

The respiratory system is responsible for the balance of oxygen and carbon dioxide in the body to meet metabolic demands. The way a person’s breathe can be affected is by emotions and/or changes in the internal environment. The breathing process is mainly controlled by the brainstem and peripheral system. The brainstem controls several important functions of the body like arousal, breathing, and blood pressure, among other functions. In the brainstem, the medullary respiratory center consists of…

cardiovascular system is also called the circulatory system, including the heart, blood vessels, blood. It is responsible for the delivery of oxygen and nutrients to the cells, the transport of carbon dioxide and…

Detox diets are thought to prevent chronic diseases, such as arthritis, heart disease, and cancer. 2. People who try a detox diet often find it can improve toxicity symptoms such as fatigue, joint pain, headache, pain, premenstrual syndrome, unhealthy skin, poor concentration, anxiety and irritability, frequent colds, heartburn…
