events. The histological evaluation of MI shows several stages. The coagulation necrosis mostly occurs in the central region of infarcts, and results in the stretching of myofibrils, many with nuclear pyknosis, vascular congestion, and healing by phagocytosis of necrotic muscle cells. The contraction band necrosis (or coagulative myocytolysis) results from severe ischemia followed by reperfusion. It is characterized by hypercontracted myofibrils (increased Ca2+ influx into dying cells) with…

append, the immune response likewise connects its Fc area, or "tail," to the phagocyte to kill the charge so the phagocyte and pathogen can close to each other. A run of the mill way pathogens are disposed of amid opsonization is through phagocytosis. Amid phagocytosis, white platelets encompass pathogens, and afterward pull inside their own particular films to complete them off with chemicals. The issue is that the layers of the phagocytes and pathogens are both contrarily charged, implying…

Within each of us, there is an immune system that works hard to keep us healthy and devoid of disease and infection. Composed of white blood cells, the immune system functions to identify and destroy foreign substances, known as pathogens or antigens. In the case of an autoimmune disease such as systemic lupus erythematosus, abbreviated SLE, the immune system does not function as it should. Instead of attacking and destroying foreign invaders, the immune system reacts to the body’s own healthy…

Glial Cells are supporting cells in the nervous system (central nervous system [CNS] and peripheral nervous system [PNS]) which aid in the efficiency of neural operations in the nervous system, (Carlson, 2013). Carlson (2013, p.36) indicates the general functions of the glial cells as: keeping neurons in place; supplying neurons with nutrients and the chemicals needed to communicate with each other; protecting neurons from each other to promote coherent messages; and “destroying and removing the…

Echinacea works by stimulating the immune system. Whereby antibiotics destroy both good and harmful bacteria Echinacea enables your body to deal with infections and viruses as they happen. Studies show that Echinacea stimulates phagocytosis, a process where white blood cells travel around the body hunting and attacking harmful micro organisms releasing chemicals and digesting them. White blood cells are a major component of the body's inbuilt quick response immune system. Echinacea increases the…

Synapses are the basic functional units in Central Nervous System (CNS). The synapses enable neuron-to-neuron communication via releasing and uptake of neurotransmitters. The synapse formation is modulated by specialized CNS cell type, glia. The glia modulates neuronal function via synapse formation, modification and elimination and, the glia even affects reorganization of neuronal circuit. Understanding cellular and molecular interactions of these glial cells is of great importance because they…

Propels food along the digestive tract, responsible for contractions of GI tract, regulates mobility of GI tract. The muscularis externa of the stomach is modified because other muscularis externa is composed of two layers: the inner circular layer and the outer longitudinal layer. However, the muscularis externa of the stomach contains a third innermost oblique layer. This third innermost oblique layer relates to the function of the stomach because it is the smooth muscle that is responsible…

Introduction Influenza A virus is a respiratory pathogen that seasonally causes approximately 200,000 hospitalizations every year in US alone and affects human health worldwide extensively [1]. Seasonal viruses circulating in the human population cause annual epidemics with about 500,000 deaths per year. Furthermore, novel strains of influenza A virus without pre-existing immunity could cause a global pandemic with a high fatality rate; the 2009 H1N1 pandemic caused 151,700–575,400 deaths in…

aureus and platelets to occur (Vanassche et al. 2012). Decreasing staphylothrombin will impact the Staphylococcus aureus, which ultimately, inhibits the amount of platelets being activated (Vanassche et al. 2012). Fibrin clots protect cells from phagocytosis, and as a result, they will persist and cause staph infections (Cheng et al. 2010). All clinical isolates of S. aureus are known to be…

to transport substances, and they both require energy. Endocytosis is a form of transport that allows a cell to engulf fluids and large molecules and bring them into the cell, and it has two main forms: pinocytosis and phagocytosis. Pinocytosis brings in fluids, while phagocytosis brings in solid particles. Exocytosis is a form of transport in which vesicles containing cell secretions fuse with the cell membrane. 10. Give an example of how natural selection maintains some genetic…
