to the lowering of blood pressure. In order to treat hypertensions on must lower blood pressure that is at a high rate into a more standard rate. The Angiotensin converting enzyme, also know as ACE, is a main component of the Renin angiotensin aldosterone system in…

contributed to the acid-base disturbance (Kahn & Cherney. 2017). Since she was dehydrated and vomiting, contraction alkalosis occurred. This is when hydrochloric acid (HCL) is reduced in the stomach and the body tries to compensate by releasing aldosterone and then reabsorbs HCO3 into the blood (Lewis, 2016). If the condition is not treated the respiratory and renal systems will try to compensate for the acid-base…

Subsequently, renin promotes the conversion of angiotensinogen to angiotensin I. Angiotensin I is then converted to angiotensin II through the angiotensin converting enzyme. Due to angiotensin II being a potent vasoconstrictor, it also stimulates aldosterone secretion leading to sodium and water retention. The subsequent renal retention of sodium and water, coupled with an increase in heart rate and contractility, ultimately leads to an increase in preload and afterload, which further…

found in up to 5 % of patients undergoing radiological imaging. As high as one in five incidentalomas are functional; hypersecretion of cortisol causing Cushing’s or Subclinical Cushing’s Syndrome (SCS), catecholamines leading to pheochromocytoma, aldosterone resulting in primary aldosteronism (Conn’s syndrome), androgens leading to virilization of patients, and in very rare cases renin manifesting as secondary aldosteronism. Renin is a proteolytic enzyme that is synthesized by juxtaglomerular…

Hypertension or otherwise known as High blood pressure is defined as a high force of blood pushing on the walls of the arteries during the flow of blood. Blood pressure is measured as the heart pumps and as the heart fills and rests in between heartbeats. This is called systolic pressure and diastolic pressure. They are both measured in milliliters of mercury. Those with a systolic pressure of over 120 and a diastolic pressure of above 80 are clinically defined as having prehypertension and…

Introduction The cardiovascular system provides appropriate organ and tissue perfusion at rest and at times of stress by regulation of blood pressure (BP). BP can be expressed as the product of cardiac output (CO) and peripheral resistance. The arterial pressure level at any given time reflects the composite activities of the heart and the peripheral circulation.(Jones, 2004). Nervous system, hormonal and Kidney factors control blood pressure. 1. Nervous System 1.1 CO – Cardiac output CO…

perfusion to the kidneys leading to activation of the renin-angiotensin-aldosterone cycle and the baroreceptors in the aortic arch, carotid sinus. This stimulates of vasomotor regulatory centers in the medulla, which in turn activates the sympathetic nervous system release of epinephrine and norepinephrine from the adrenal glands causing constriction of arteries to increase blood pressure. The activation of the renin-angiotensin-aldosterone cycle leads to the retention of sodium and water,…

Should Adrenaline Fatigue Patients be Tested for Iodine Deficiency? In the human body, iodine deficiency and adrenaline fatigue are correlated. This phenomenon is not new to the world of medicine. Yet, it is largely ignored, inadequately researched, and poorly understood by scientists, physicians, nutritionists, and medical practitioners all across the globe. This article focuses on the link between iodine deficiency and adrenaline fatigue. It also stresses on the need for adequate iodine in…

The Deepwater Horizon Oil Spill was a tragic mishap on BP’s behalf, killing several rig workers and having many other outreaching effects. The amount of crude oil that was spilled into the Gulf of Mexico over the course of approximately three months was 4.9 million barrels of oil and to go along with that, 2 million gallons of chemical dispersants to the Gulf. A major group of crude oil, polycyclic aromatic hydrocarbons (PAH) was discovered along the northern shorelines of the Gulf of Mexico.…

Joanne’s body responds to hypovolemic shock by triggering the cardiovascular, renal, hematologic and neuroendocrine system for support. The Hematologic system responds to major blood loss by activating coagulation cascades and constricting the vessels that are currently bleeding by release of thromboxane A2 and platelets. What this does is form a colt on the bleeding site. Collagen is exposed by damaged vessels which cause fibrin production and stabilize the clots that have been formed. Usually…
