Brachial artery

Arteries Arteries carry blood at high pressure (80 - 120 mm Hg) They have a narrower lumen (to maintain high pressure) surround by a thick wall made of two layers The middle layer (tunica media) contains muscle and elastin to help maintain pulse flow (it can contract and stretch) The outer layer (tunica adventitia) contains collagen prevents the artery rupturing due to the high pressure blood flow Veins Veins carry blood under low pressure (<10 mm Hg) They have a very wide lumen (keeps…

Blood Pressure: Systolic and Diastolic Abstract Blood pressure is when your heart beats and so it pumps blood back up to your body for it to have energy and oxygen. However, as your blood pushes it creates strength, so this creates blood pressure. Pulse is to see the rate of your heart going beats per minute. In this experiment, we gather data to see if the level of physical activity could affect the result of the systolic and diastolic measures in blood pressure and if the pulse would also be…

Forskolin This Forskolin substance that people are talking about is a natural medical herb. It comes from the base or the root of the Plectranthus barbatus plant. Forskolin is a member of the mint conglomerate which is fathered by the plant Coleus forskohlii. For many years, natives of Thailand, India and Nepal have used Forskolin to mend heart problems, angina and even hypertension. Apparently, the substance acts within the heart muscles and walls of the blood vessels to render an…

Pre-hypertension will eventually lead to hypertension, those with a systolic pressure between 120 and 139, and a diastolic between 80 and 89 on multiple readings (“Hypertension,” n.d. ). This is a condition in which the force of blood against the artery wall is too high. Hydralazine medicine is also used for high blood pressure patient. It is effective in helping to reduce blood pressure, and often used as combination with other drugs especially if the patient is in a hypertensive…

Cardiac and respiratory conditions can be very hard on the child and the families of the child. There are many different cardiac and respiratory conditions that can affect a child, as well as their families. The great thing is that many of these conditions we are able to treat. The cardiac condition that I decided to research is the Tetralogy of Fallot and the respiratory condition is Respiratory Distress Syndrome. Tertralogy of Fallot is a birth defect and affects normal blood flow. During…

blood vessels or the branches of the arteries. As the Aneurysm grows it tends to get larger in the walls of the arteries which can cause discomfort. There are two main types of aneurysm: cerebral aneurysm and aorta aneurysm. An aneurysm can be diagnose with .Regular screening or x-ray, and once taken place, the doctor can determine if surgery is needed to take Place or if you can watch and wait how it processes throughout the body. Key word: Aneurysm, arteries,…

Hyperlipidemia can be caused by a high fat diet. The fat accumulates on the arteries. This can narrow the arteries, which makes it more difficult for blood to pass through. This causes hypertension. The heart has to work harder to pump the blood through the narrowed arteries. If the coronary arteries become narrowed coronary artery disease occurs. The coronary arteries supply the heart muscle with blood. When blood is restricted to the heart chronic heart failure can…

There are multiple factors that contribute to the build-up of plaque in the vessels and in turn, the development of atherosclerosis (Silverthorn et al., 2009 p327). The disease attacks different arteries in the body, but the most harmful conditions involve damages to the vessels of the brain and the heart (Silverthorn et al., 2009 p329). Understanding of the structures and mechanisms that take place in the heart and the brain to allow for blood distribution is a critical component for anyone…

In case of pacing the coronary heart rhythm from ventricular conduction device, the price slows right down to 30-40/min and QRS complexes on the ECG are wider than 120 ms. In ventricular traumatic inflammation the depolarization of cardiomyocytes is caused by several mechanisms – reentry, induced hobby, ectopic foci of excitation or mixture of these. In ventricular traumatic inflammation (VF) the heart paintings is useless, fibrillating ventricals are not pumping blood and the circulation stops.…

Interrelated Concepts: The interrelated concepts with perfusion are pain, clotting, inflammation, patient education, nutrition, mobility, gas exchange, elimination, and cognition. Perfusion affects all the systems in the body, because when tissues and organs do not get perfused properly they do not function the way they are supposed to. The first concept is pain, decreased oxygen flow to tissues can cause pain, which is what can happen with anemia because there is a decreased ability to carry…
