Primary active transport - movement from regions with low concentration to high, requires ATP to function, involves the movement of ions like hydrogen, calcium, sodium, and potassium (Vander et al., 2001).
c) Ca-ATPase – this system pumps the calcium ions to the extracellular fluid from the cytoplasm. Besides, in the organelles, it involves pumping of calcium to the lumen of the organelles from the cytoplasm. It utilizes ATP as a source of energy
d) Na-K-ATPase – this system pumps two molecules of potassium in the cell while removing three molecules of sodium from the cell through the hydrolysis of energy. This makes the intracellular negative relative to the extracellular environment of the cell (Vander et al., 2001).
The difference in charge between the inside and the outside of the cell affects the movement of cations and ions across the membrane. When there is a net charge difference the cations and anions will move in the direction with a low concentration of the molecules until both sides of the cells attain an equilibrium during which the cell would be referred to be in a resting membrane potential (Vander et al., 2001).
Monogenetic inheritance is called so because it involves a single genetic disease. The changes in DNA sequence happens at a single genetic code. The modes include X-linked (sex-linked, and sex-limited), autosomal recessive, autosomal dominant, abnormal mitochondrial gene (Vander et al., 2001).
Hormonal hyperplasia is a type of abnormal medical condition that involves proliferation of tissues involved in the production of hormones. The proliferation leads to increase in the production of the chemical substances called hormones. In the hormonal hyperplasia, the general structure of the cell or the tissue remains the same even after the proliferation.  ...Download file to see next pagesRead More

...) found that high fat diet is likely to increase the risk of Crohn's disease and ulcerative colitis. This is in addition to other related health issues which the body would have to deal with if too much fat is introduced in the body. According to Wang (2012; 367) due to the fact that the heart produces natriuretic peptides as a way to influence the functions of the other organs of the body also means that metabolic disorders are more likely to lead to unprecedented and cardiovascular risk in human beings. In this regard, high fat diets are most likely to affect the cardiovascular health of the individual. However, while alcohol is a significant concern on heath risk, diet issues are also highly serious issues. This can be...

...within minutes after administration or exposure to the specific antigen and is manifested by respiratory distress, often followed by vascular collapse or shock without antecedent respiratory difficulty. Cutaneous manifestations exemplified by pruritus or urticaria with or without angioedema are characteristic. Along with that, there may be gastrointestinal manifestations like nausea, crampy abdominal pain, vomiting, or diarrhoea. The materials that are able to incite an event like this may be many, among them the drugs like penicillin, insulin, antisera, local anesthetics, and other environmental agents are listed (Ewan, P.W., 1996). We will look into the pathophysiology in...

...The changes in cardiac enzyme levels include the elevated troponin I, elevated myoglobin, elevated CPK and cardiac troponin T. However, cardiac troponin T, and I are the most common marker of myocardial injuries due to their high specificities and sensitivities for diagnosis of acute myocardial infarction. Question 3 The most common pathophysiologic precipitating event s of ACS are plague rapture, hypertension, chest discomforts and pains that spreads to the left arm and lower jaws. The chest pains are usually associated with sweating and nausea. The other precipitating events can include anemia, acute thrombosis that is induced by rapture and an unstable angina. Bradycardias or excessive slow heart rate and tachycardias...

..., arterial stiffness, plasma volume, genetic influences all contribute to these changes. Usually, the people suffering from hypertension in young age group are found to have normal left ventricular structure (Mayet & Hughes, 2003). In view of the complicated pathophysiology of essential hypertension as described above, treatments routes are also wide and varied. It has also been found that family history contributes significantly. That means genetics play a much bigger role than environmental factors. When both the parents suffer from hypertension then possibility of their child to suffer from hypertension increases by 250%. That is why certain races such as African Americans...

...Left-Sided Congestive Heart Failure due: Describe the common causes of left-sided congestive heart failure. Discuss the disorders that typically result in left-sided failure. What are the classic signs and symptoms of left-sided failure? Left-sided congestive heart failure is a fatal condition whereby the heart fails to pump sufficient blood to the body due to a malfunctioning left ventricle. It can manifest in two ways: systolic or diastolic failure. Systolic failure occurs when the left ventricle fails to contract strongly enough to push blood through the body, while diastolic failure occurs when the left ventricle cannot relax enough to allow in more blood due to stiffening of the muscles. Common causes of left-sided heart... Congestive...

...Pathophysiology Due In this essay, I will discuss on various interventions to be recommended to a 54-year-old man with a risk of smoking and a high-fat diet. Cardiovascular disease is an illness that affects the heart organ. For this particular patient, a change in lifestyle will do him much more than medicine. The most essential primary preventive measures are proper diet, avoidance of stress, stop smoking, regular exercise (Balakrishnan, 2004). However, age and gender is non-modifiable risk factors meaning there is nothing much that one can do to modify them. Five interventions that include: 1. Proper diet To manage his lifestyle, the patient should minimize the fat intake through consumptions of energy dense foods that...

...Pathophysiology due: Tineasha Woods response essay I agree with Tineasha Woods that Asthma is an illness that has an impact on the small tubes that transport air in and out of the lungs. It is caused by triggers which are things that cause irritation to the airways. There are two kinds of treatment given to asthma patients that are controllers and relievers. Reliever inhalers are prescribed to reduce the asthma signs, and they do not minimize the swelling and inflammation in the airway (Wojciechowski, 2011). People suffering from mild asthma are treated with inhaled corticosteroid combined with a long-acting beta-two agonist (Wojciechowski, 2011). In such a case Flovent 110 and Severent is prescribed. Flovent is...

...Pathophysiology Pathophysiology Three possible factors that may have been responsible for the development of the stone are age, gender, and previous medications. First, urinary calculi are common more in men aged between 30 and 50 years than in women. Second, the sales clerk had a history of taking non-prescribed pain drugs. Medications such as acetazolamide and Crixivan can induce the formation of kidney stones (Editore, 2014). The patient’s diet and fluid consumption can help analyze the composition of the calculi by determining the nutritional values and amount or frequency respectively. If the patient consumed a diet rich in proteins, sodium, and sugar, then he unknowingly contributed to the accumulation of the kidney stones... Pathophysio...

...Pathophysiology Diagnosis The physician should give Mr. Ally an eye exam. The examination should encompass dilating the eyes todetermine whether the retina is detached. Fundamentally, the physician should utilize the ophthalmoscopy and ultrasonography in the diagnosis. The ophthalmoscopy is essential for the examination of Mr. Ally’s eyes because it offers a highly defined three-dimensional view that enables the physician to see the presence of detachment or retinal holes. Similarly, the doctor should use the ultrasonography to create images of the retina on a video monitor for the diagnosis of the retinal detachment. The two tests will be crucial in the diagnosis of the retinal detachment in Mr. Ally’s eyes. Floaters and...
