The blood consists of two major portions: blood cells and plasma. The functions of the cardiovascular system: the cardiovascular system is so important to our body, that if it stops for a minute, rapid death will occur. The flow of blood is necessary for existence of life. If the flow of blood stopped, life will stop. Cardiovascular system has three main functions: Transport of nutrients, oxygen and hormones to cells throughout our body and removal of metabolic wastes such as (carbon dioxide and nitrogenous wastes).
The sequel of refeeding syndrome adversely affect nearly every organ system and include cardiac dysrhythmias, heart failure, acute respiratory failure, coma, paralysis, nephropathy, and liver dysfunction. The primary cause of the metabolic response to refeeding is the shift from stored body fat to carbohydrate as the primary fuel source. Serum insulin levels rise, causing intracellular movement of electrolytes for use in metabolism. The best advice when initiating nutritional support is to "start low and go slow". Recommendations to reduce the risk of refeeding syndrome
Describe the four valves of the heart, including their name, location, and function. The four valves of the heart are the tricuspid valve, the pulmonic valve, the mitral valve, and the aortic valve. The tricuspid valve: It is located between the right atria and the right ventricle. It is comprised of three “flap-like cusps” which when in its closed position, prevents the deoxygenated blood entering the heart from the body, from backing up in the right atrium from the right ventricle (regurgitation). http://www.healthline.com/human-body-maps/tricuspid-valve The Pulmonic Valve: This valve is found between the right ventricle and the lungs.
The heart consists of 2 ventricles, and also 2 atria. There is a right atrium and also ventricle, this is where the blood comes from the veins. The deoxygenated blood then goes into the right atrium of the heart. Blood is released from the atrium and goes into the right ventricle, this happens when the heart relaxes, this is where the right ventricle pushes blood in through pulmonary valve and eventually into pulmonary artery, this is the place where the blood its given to the lungs because to get back oxygen. Lastly the blood is then given back to hearts left side.
Anatomy & Physiology Chapter 19: Vascular * Contrast the structure and function of the various types of blood vessels * Explain how the venous blood is returned to the heart * Explain blood pressure and pulse * Discuss the factors that affect blood pressure * Contrast the clinical significance of systolic, diastolic, and pulse pressure * Discuss the mechanism of capillary exchange * Describe blood flow through systemic and pulmonary circuits. Identify the principal arteries and veins of the systemic, pulmonary, and hepatic portal circulations * Describe unique aspects of fetal circulation * Explain the effects of exercise on the cardiovascular system * Describe significant cardiovascular diseases
CARDIAC Catheterization * Insertion of a catheter into the heart and surrounding vessels * Determines the structure and performance of the heart valves and surrounding vessels * Used to diagnose CAD, assess coronary patency, and determine the extent of atherosclerosis. * Pretest: Ensure Consent, assess for allergy to seafood and iodine, NPO, document weight and height, baseline VS, blood tests and document the peripheral pulses * Fast for 8-12 hrs, health teaching, medications to allay anxiety. * Intra-test: inform patient of a fluttery feeling as the catheter passes through the heart; inform the patient that a feeling of warmth and metallic taste may occur when dye is administered * Post-test: Monitor VS and cardiac rhythm * Monitor peripheral pulses, color and warmth and sensation of the extremity distal to insertion
“Meth causes the blood vessels to constrict; it cuts off the steady flow of blood to all parts of the body. Heavy usage can weaken and destroy these vessels, causing tissues to become prone to damage and inhibiting the body's ability to repair itself.” (Visible Signs, paragraph 1) A really big appearance change that happens when using this drug is the aging process. The body loses the elasticity and luster that causes you to look young in such a short amount of time. Another really bad thing that can happen to your body with all the Methamphetamine use is the hygiene of the mouth. “The drug causes the salivary glands to dry out, which allows the mouth's acids to eat away at the tooth enamel, causing cavities.” (Meth Mouth, second
Chronic heart failure means ongoing, acute means it started suddenly. Below are some signs and symptoms of chronic heart failure 1. Shortness of breath, 2. Fatigue or weakness 3. Swelling in your feet legs ankle 4.
Other than the digestive system, numerous body systems are affected, because blood sugar is essential to maintaining bodily functions. The circulatory system is impacted, because of irregular blood levels. Diabetics are at a higher risk for heart disease. If blood sugar levels are not regulated, an excess
Thus action at both societal and individual levels should be implemented to better the nutrition and physical activity practices. Cardiovascular health involves coronary heart disease, stroke, heart failure, peripheral vascular disease. “…The main underlying causal mechanism of cardiovascular disease is atherosclerosis, a process marked by abnormal build-ups of fat, cholesterol and other substances in the inner lining of the arteries. It is most serious when if affects the blood supply to the heart (causing angina or heart attack) or to the brain (causing a stroke)…” (http://www.aihw.gov.au/nhpa/cardiovascularhealth/index.cfm). The
