Address each of the following regarding Teri’s case: Since the parietal cell is destroyed, which substance(s) is Teri lacking as a consequence? What is the correlation between the destruction of parietal cells and Vit B12 deficiency? Due to her condition, Teri lacks Pepsin. Explain why. If Teri were healthy, explain what her RBCs would look like. What is hematocrit?
Pernicious Anaemia Case Analysis
The loss of the parietal cell caused a vitamin B12 deficit that made Teri more susceptible to pernicious anemia, which has deteriorated her condition over time. In this situation, Teri doesn’t have an intrinsic factor created by the parietal cells. Parietal cells are situated at the fundus and stomach body. They consider the movement, vitamin B12 absorption, which the ileum uses to produce red blood cells, and its damage causes pernicious anemia (Rodriguez & Shackelford, 2022). In the case of pernicious anemia, the body reacts by creating antibodies that target and eradicate the parietal cells. Significant harm from extreme disruptive anemia includes digestive system issues and nerve damage. An enzyme called pepsin aids in the activation of pepsinogen. Since Teri’s stomach lacks parietal cells that release hydrochloric acid, the pepsin has stayed dormant. Cell death in the parietal region in the stomach lining will signal the body to release hydrochloric acid where it is intended to do so because it is effective at decreasing the stomach PH. The kidney releases the hormone erythropoietin when there is a lack of oxygen, which promotes red blood cell growth. In the hemopoietin organs, division aids in the stimulation of erythropoiesis (Rodriguez & Shackelford, 2022). The kidney produces red blood cells due to the activation of hemopoietin tissues, which help address the oxygen deficit. However, the erythropoiesis pathway occurs in the liver or spleen in people with specific disorders as opposed to the bone marrow.
Introduction
Different body systems that perform particular tasks to support the body’s regular operation make up human systems. The digestive, immunological, and cardiac systems are a few of the systems. The gastrointestinal system disintegrates the meal, and it is simple for the system to digest these elements in the form of nutrient content that improve the sustenance of the cells when liquids are incorporated into the chemical components, for example, fats and proteins. The system also takes energy that enhances its operation from the absorbed elements within the digestive system. White blood cells, bone marrow, immunoglobulins, and other components of the immune system combat pathogens like viruses and bacteria and eliminate them from the system (Rodriguez & Shackelford, 2022). The immune system also detects and counteracts potentially hazardous compounds that the body absorbs from the surrounding. Regulating blood circulation to all body systems requires the proper functioning of the cardiac system. I will discuss the findings concerning Teri’s situation in this essay.
Substances Absent in Terry
Teri does not possess an intrinsic factor in this situation. The parietal cells, found at the stomach fundus and body, are responsible for producing this component. The component helps the small intestines transport and absorb vitamin B12 to create red blood cells; their failure causes pernicious anemia (Rodriguez & Shackelford, 2022). In the case of pernicious anemia, the system reacts by producing antibodies that target and kill the parietal cells. Consistently chronic pernicious anemia may seriously harm nerves and cause digestive system issues.
