Different Operations of the Organ Systems - Essay Example

Homeostasis Homeostasis Human beings require different operations of the organ systems to regulate its temperature and water for effective body function. Biology as a discipline attempts to understand how individuals survive through the process of homeostasis whereby both internal and external conditions are regulated. It also defines the role of the endocrine system with emphasis on its production of glands that maintain the glucose and blood levels (Schulkin, 2003). However, consequences exist that can occur if the homeostatic process is disrupted especially for the mother. For example, cases of high blood pressure and aging are the foremost negative effects that should be avoided. This is because they could lead even to the eventual death of the person. The body system is requires consistent regulation in order to allow other functions to remain constant. Therefore, homeostasis as a biological function is tasked with regulation of the internal conditions to ensure that the human body is stable. On that account, as a medium of maintaining a dynamic range of environmental qualities, homeostasis possesses control mechanisms that have receptors of sensing stimulus. This means that information is sent to a particular control center that determines various stimuli that often elicit a change in organs, muscles, and other vital body structures (Szablewski, 2011). Therefore, instead of holding an internal environment within a given point, homeostasis has the potential of giving a negative feedback that reduces the activity of the organ systems and any other output. Regulation of blood pressure, for instance, is the operation of the negative feedback especially when it assists in the decrease of the heart rate through vasodilation. However, with a set point instead of working range of temperatures, the body can get overworked. This is because the negative feedback mechanism is devoid of regulatory changes that respond effectively to the stimulus. Consequently, a homeostasis imbalance necessitates inefficiency and defective body control systems. A set point equally results to an internal environment with physical changes, risk of illnesses and aging that could destabilize the overall body system. Alternatively, a homeostatic imbalance creates a high concentration of salt in the blood system causing a decline of oxygen in the body. It, thus, generates a chain of homeostatic emotions that include thirst, breathlessness, and warmth (Wood et al., 2012). Likewise, a set point is retrogressive in the body system because it fails to restores vital operations of human efficiency such as drinking water or removing a sweater because of imbalanced body temperature. Overall, it indicates that the internal conditions of an individual depend on a regulated temperature without a set point. The endocrine system is instrumental in the homeostasis function particularly in instigating hormonal signals to assist in biosynthesis and recognition of other cell membranes. The system also has the role of producing hormones to facilitate essential body functions. It means under the endocrine system, there are hormones that play other pertinent roles worth noting. The adrenaline, for instance, that comes from the adrenal glands aids in triggering a sense of fear during times of danger. This results to an increase in breathing rate, high heart rate, dilated pupils and increased alertness (Schulkin, 2003). In other words, the hormone is efficient in eliciting an immediate response that prevents a person from succumbing to harm. Another one is the human-growth hormone (HGH) produced by the pituitary gland and assists in the manipulation of body growth. Accordingly, dwarfism emanates from inadequate HGH especially for children and this could also result to poor growth and development. Similarly, the best solution involves an early diagnosis and of injections of HGH. Again, excess HGH could cause a child to develop an abnormal gigantism. In case the hormones are disrupted in their actions, there are expected consequences on the growth and development of a person. For example, children may suffer effects of dwarfism that limits their overall growth. This usually hampers the individual from developing self confidence and self esteem integral in harnessing socialization skills. An imbalance in the control of glucose level is another effect of hormonal disruption that often kills body cells unless checked early. In retrospect, the damage spreads to body organs that include the pancreas that has glucagon and insulin instrumental in maintaining the blood glucose at an acceptable range (Szablewski, 2011). Contrastingly, diseases such as diabetes result from high glucose levels in the body system because of severe hormonal disturbance at critical stages. Maintenance of homeostasis accords individuals greater freedom and limits dependence on other changes from the external environment because of numerous reasons. This implies that temperature variation operates according to environmental conditions that retain a body temperature specifically for warm-blooded animals such as birds and mammals. Metabolic action, on the other hand, is central in the regulation of the body Ph in terms of acidity and alkalinity. It demonstrates the relationship between additional energy and automatic regulation system that ensure organs and cells act at certain levels. Conversely, while blood glucose concentration assists the body in maintaining a dynamic equilibrium, it also helps in cellular metabolism that gives the body independence on the internal conditions (Wood et al., 2012). It is a phenomenon evident in the removal of excess ions and water from the blood system while performing other key homeostatic regulation functions. Notably, sleep propensity is achieved via interdependent components that come from receptors and other control mechanisms. On that note, during extremes that compel our bodies out of homeostatic bounds, there are negative repercussions that are likely to happen. A case in point is overheating of the body system if both the internal and external temperatures are not balanced. This often causes a surge in the blood pressure causing vasoconstriction because the individual has low supply of energy. Additionally, the metabolic demand will vary hence causing a set-point that lowers the normal value important in temperature control (Schulkin, 2003). It is interlinked with the hypothalamus that critically monitors slightest variation of body temperature when homeostasis overworks itself. Generation of homeostatic emotions could also occur, thus, resulting to severe thirst and breathlessness. In that context, oxygen and blood decline in form of concentration levels because of unregulated homeostatic balances. Alternatively, chemical composition is adversely affected because it interrupts the supply nutrients for the body. Development of new humans depends wholly on the maintenance of homeostasis because of the control mechanism involved. This involves the functions of the endocrine systems that produce the pituitary gland essential in the success of human-growth hormone (HGH). It is a crucial hormone efficient in the control of glucose levels for the child still attached to the mother. Contrastingly, while glucose levels initiate control systems that neutralize the internal environment, it prevents the mother from illnesses and aging that may affect the child. Motivation of behavior is another ramification of a homeostasis balance when new humans grow and develop while retaining most of their innate characteristics (Szablewski, 2011). It is a fundamental element of negative feedback through temperature control because of the variations that stimulate pertinent glands that affect sweating for the mother. The development is equally critical because it maintains homeostatic emotions of motivating behavior and restoring temperature for both the new born and mother. Disruption of specific homeostatic functions could elicit certain bodily changes that include high blood pressure and a metabolic demand for the mother and child respectively. On the other hand, while the endocrine system is vital in producing pituitary glands, it could destroy the muscles that usually increase the mother’s body temperature. This forces the body to readjust itself through supply of energy and disproportionate complications in weight. Contrastingly, inefficiencies in homeostatic imbalance could cause severe physical changes that come with illnesses and other lifestyle diseases. Acid-base reactions are, hence, interrupted especially if the pH is interconnected with the blood plasma. It is a problem that spreads to the control mechanisms related to the fluid-deficient body in terms of secretion of important hormones such as ADH found in the urine and kidney. Respiration brought by low oxygen is another consequence when the blood levels are acidic and are not balanced with the Carbon dioxide. This implies that essential functions such as osmoregulation are hindered by the concentration or dilution of ions and water found in the mother’s blood (Wood et al., 2012). Consequently, this causes an extracellular volume and long-term blood pressure while disrupting the regulation of the renin-angiotensin system (RAS). The mother will, thus, suffer from low calcium and calcium-sensing receptors that are often activated by the parathyroid gland. Alternatively, it leads to bone-degrading cells that could cause the new human to contract early rickets. An increase in blood calcium is also endangered if the absorption of urine is not regulated by the homeostatic function. It, thus, is imperative human beings to strive at eating healthy foods and exercising daily to maintain both the internal and external body temperature. This is instrumental because it deflects diseases and maintains the glucose levels found in most of the organ systems. Individuals should also visit physicians to ensure that their pH levels are constant with the required acidity-base level (Schulkin, 2003). It is a preventive strategy keeps the control mechanisms alert and active through the timely response of the stimuli. References Schulkin, J. (2003).
