Renin-angiotensin system

During my undergraduate years, I came across a drug class called Angiotensin Converting Enzyme (ACE) inhibitor. This medicine interferes in a production of angiotensin II via the enzyme inhibition, ultimately lowering the blood pressure. Understanding the physiological effect of angiotensin-renin system greatly fascinated me how our body is sophisticated in its structure and function, and it intrigued me further that our current knowledge allows us to design ACE inhibitor to combat high blood pressure

affecting the blood volume, the heart will increase or decrease it’s contractility overall changing the systolic blood pressure. With congestive heart failure, the act of sodium, chloride, and water retention is detected. This is in result of the Renin-Angiotensin System. When there is a decrease in

Renin Angiotensin Aldosterone System (RAAS) is the system that regulates blood pressure in the body. When the body detects low blood pressure (low fluid/low salts), the liver releases angiotensinogen (Bayer pharma, 2015). The release of the angiotensinogen is the beginning of the signal transduction pathway (Bayer pharma, 2015). The angiotensinogen and renin react together to form angiotensin I, then angiotensin-converting enzyme (ACE) converts angiotensin I into angiotensin II (Bayer pharma

Question 1: An unaltered consciousness occurs when the Renin-Angiotensin (RAS) system is working at 100% (Blyth & Bazarian, 2010). When changes such as head traumas, aging, concussions, strokes, etc. occur the RAS system would be damaged overtime (Barritt & Smithard, 2011). The more often these occur, the more it is damaged. If RAS does not seem to be working adequately it would mean that it is not be properly communicating with the cerebral cortex, this then causing the patient to become less

Renovascular hypertension, also known as renal hypertension, is a condition in which chronically elevated high blood pressure is caused by a narrowing of the renal arteries. The renal arteries are the arteries that bring blood to the kidneys (9). This blood is processed by which the kidneys filter the blood, removing some substances and sometimes adding others. The kidneys also have several functions, which can be negatively affected by renovascular hypertension. One function is the regulation of

HYPERTENSION Summer 2015 Bhavneet K. Singh High blood pressure Definition: The heart is supplies the organs and tissues of the body with blood and nutrients it carries. It pumps blood into the blood vessels of the circulatory system. The blood that is pumped into these vessels puts pressure on the walls of the vessels. When the heart muscle contracts during each beat, the pressure rises as well. Blood pressure may be different at different times of the day. It is usually higher when someone

In the modern medical society, scientists/doctors have adopted the use of medicines known as Angiotensin-converting enzymes or ACE inhibitors which are ideal for treating kidney, blood vessel and heart problems (Updated by: Michael A. Chen, 2015).This particular medicine works by lowering blood pressure and ultimately manages any disease to prevent it from getting any worse. Often patients with heart failures will be prescribed with this medicine. This essay will give a detailed explanation and description

as Benazepril, is an ACE-inhibitor, or angiotensin-coverting enzyme inhibitor. These types of drugs play an important role in the RAAS (which stands for renin-angiotensin-aldosterone system). Arterial blood pressure is regulated and accomplished through neural, hormonal, and renal interaction and is in tune with the homeostatic fluid volume of one’s body. The balance of sodium and water is performed by the kidneys and the renin-angiotensin-aldosterone system is the main regulator of fluid volume in

which his characterized by snoring, sleep disturbance and day time sleepiness. There is a close relation between OSA and hypertension; as many as one-third of hypertensive patients and above 80% of those with resistant hypertension have OSA. Alcohol- Higher intake of alcohol increases the blood pressure. Reducing alcohol leads to fall in the systolic blood pressure. Stress- Psychological or environmental stress play a part in the causes of hypertension. Direct effects of situations such as poverty

maintain a balance between these factors, there are four control systems that play a role: the arterial baroreceptor system, regulation of body fluid volume, the renin angiotensin aldosterone system, and vascular autoregulation (Beeman, 2013, p. 337). Arterial baroreceptors are responsible for monitoring the levels of arterial pressure. When these baroreceptors sense a rise in arterial pressure, they counteract by slowing down the cardiac system and vasodilating (Beeman, 2013, p. 338). Changes in body fluid
