"Explain the concept of homeostasis with reference to the control of heart rate‚ breathing rate‚ body temperature and blood glucose levels" P5 Homeostasis is where the body keeps a constant internal environment. This involves all the metabolic processes taking place In the body as well as the blood‚ tissue fluid and all the contents in the body ’s cells. There are a range of variables from heart rate to the blood glucose levels that the body will take into account. Negative feedback will occur

trace** The ECG records 5 different waves that correspond with myocardial activity. The first wave is the P wave which occurs in response to atrial depolarization. Next the QRS complex occurs as a result of ventricular depolarization and may or may not include Q and S portions of the wave. Finally‚ the T wave is in response to ventricular repolarization. Atrial repolarization is not typically seen on the ECG because it happens around the same time as the QRS complex(reference text book). In order

Steven Ofstedahl BI 243 Short report Cardiac Arrest The circulatory system along with the heart make are what make up the cardiovascular system. The heart works as a pump that pushes blood to tissues‚ organs and cells in your body. The blood can be pumped throughout the body through a series of arteries‚ veins and capillaries. Arteries and capillaries send blood from the heart to all areas of the body‚ while veins help bring that blood back to the heart. Arteries carries oxygenated blood away

Sample Physiology MCQs 1. Compound action potentials can be graded responses. True 2. The sciatic nerve contains axons of both afferent and efferent neurones. True 3. The absolute refractory period of an action potential is the period after an initial stimulus when it is impossible to evoke another action potential with a second stimulus. True 4. The refractory periods of individual axons are important as they dictate the maximal action potential firing rate of a neuron. True 5. Compound action

Science in Nursing‚ also called BSN‚ is a four-year degree obtained at a university. It includes the same areas of study and has the same license upon completion of the NCLEX as the ADN nurse‚ but delves further into nursing theory as well as pathophysiology and technical skills. Many employers require the bachelor’s degree for higher positions in nursing such as clinical managers and nurse specialists. Differences in competencies between nurses prepared at the associate-degree level versus
