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…

It test how well you inhale and exhale, and it also test how much air your lungs take in with each breath. To perform this test, an instrument called a spirometer is used which measures the volume of air moving in and out of the lungs during pulmonary ventilation. When given this test a person can be standing up or sitting down but whichever one that person must remain in that position throughout the whole test. The person cannot change positions because that will mess of the results from the…

states surrendered, photographic images of Lee showed a rapid age progression. Several sources indicate that he seemed to age 10 years in a matter of months. The war had taken a huge toll on the general. His age combined with more frequent ischemic heart disease related symptoms led to his death on October 12,…

2004); (ii) an increase in lactate elimination from the muscle; (iii) lactate transportation to other tissues (liver, heart, muscles) where it can be oxidized or used as a substrate for glucose resynthesis; or (iv) a combination of these 3 factors (Gollnick et al. 1986; Neric et al. 2009). Several studies have suggested that maintaining a level of activity, even low, generates…

waste. The elements of the system include; The Heart The heart acts as a muscular pump which is divided into 4 different chambers, the heart's main function is to pump the blood around the body. It pumps deoxygenated blood through the veins, to the lungs for oxygenation which can then be pumped into the various arteries. The transported blood therefore transports oxygen, hormones and nutrients to body tissues. The four chambers in the heart are known as the right atrium, left atrium,…
