filling. 6) what is left ventricular hypertrophy? Why would G.L condition cause left ventricular hypertrophy? Left ventricular hypertrophy is when the heart muscle is thickened the chambers are stiff and thick and this does not allow the heart to fill. 7) what does the inverted T- wave indicate? Why does it appear only when the patient exercises. T wave indicates repolarization of ventricles. And when exercising the demand of ventricles high but the recovery of the ventricular muscle is not…

Capecitabine, an oral 5-fluorouracil (5-FU) analogue, is a commonly used chemotherapeutic agent (antimetabolite) of the pyrimidine analogue family. It is a basic cytostatic agent used in therapy of solid gastrointestinal cancers (as adjuvant therapy as well as in treatment of metastatic disease); besides, it is also widely used in therapy of metastatic breast cancer. Myocardial infarction is a rare adverse effect related to capecitabine therapy. We present case report of a female patient with no…

Neurons are the cells specialized to receive, conduct, and transmit signal to the nervous system. The development of neurons starts early during the embryogenesis. After the fusion of sperm and egg, zygote is formed which is further divided to form blastula eventually leading to gastrula stage of development. Gastrulation begins as invagination of cells in the embryo leading to the formation of three germ layers. Formation of notochord from the mesodermal layer marks the beginning of neurulation…

how our body can function. Both are a part of the circulatory system. There are many diseases that can affect the cardiac cycle and the BP. These diseases can affect our circulatory system, lungs, and our heart’s ability to function properly. When the cardiac cycle and BP are affected then the body is in danger of being greatly damaged. The cardiac cycle is what causes the BP to rise and fall. This occurs first through a ventricular contraction. When this contraction of the ventricles happens…

3. Explain the heart generates and conducts an electrical current. Page 388 The heart has its own built-in conduction system for generating action potentials spontaneously and coordinating contractions during the cardiac cycle. All the cardiac muscle fibers in each region of the heart are electrically linked together. The intercalated disks are connections that electrically join the muscle fibers of the heart into a single unit that can conduct electrical impulses through the entire wall of…

Pathophysiological Effects (Cardiovascular Responses) of Excessive Exercise Abstract The cardiovascular system is a complex system that contains the heart, the blood as well as the vasculature. Its purpose is to receive oxygenated blood from the lungs and pumps the oxygenated blood to the rest of the body (organs and skeletal muscles). During exercise there is an increase in the supply of oxygen to the working muscles, this happens so that there is an increased generation of adenosine…

results on its impact to health, life, and the human body. Many studies have been done regarding the effects of repetitive participation in vigorous physical activities and the changes in the human body, especially in respects to the cardiovascular system and the observed changes of myocardial structure and function (Baggish & Wood 2011). But what is the impact of these changes? It is well known that exercise benefits the heart which, as important as it is, is a muscle and thus can be…

Warning heavy on the Science This is a condition that arises when there is too much fluid in the tissue spaces or the cavities of the body. This can result in congestion, in inflammation the fluid accumulation we see is normal, this is part of the process, where the fluid that is rich in protein goals to the area. This is different from noninflammatory edema, where the fluid that accumulates in the is not risk in protein. This is due to the osmotic and hydrostatic pressures between the…

used psychoactive drugs, is a central nervous system stimulant that induces the sense of alertness and awareness. Inspired by the previous research on how the caffeine affects the cardiovascular system, we wanted to test the effect of different concentrations of caffeine on the heart. We used ECG stimulator on LabScribe 2 software to monitor the heart rate. We used frogs as a test subject, since both frogs and humans have a closed cardiovascular system, therefore the effect on the frog’s heart…

FLUCYTOSINE Also known as 5-flurocyrosine or 5-FC. It’s an antifungal drug that is usually formulated with amphotericin for wide range of medical uses, it can be used by mouth for treatment of infections that could be caused by Cryptococcus neoformans or perhaps candida. It could also be used in the treatment of chromblastomycosis (chronic fungal infection of subcutaneous tissue or skin). Because of its weak antifungal action it can’t be used alone for treatment of serious, life threatening…
