Gingivitis The longer plaque and tartar are on teeth‚ the more harmful they become. The bacteria cause inflammation of the gums that is called "gingivitis." In gingivitis‚ the gums become red‚ swollen and can bleed easily. Gingivitis is a mild form of gum disease that can usually be reversed with daily brushing and flossing‚ and regular cleaning by a dentist or dental hygienist. This form of gum disease does not include any loss of bone and tissue that hold teeth in place. [pic]Back to top

Kate Marsh 04 April 2014 Congestive Heart Failure Heart failure affects almost 6 million Americans. About 670‚000 people are diagnosed with heart failure each year. It is also the leading cause of hospitalization in people older than 65. Congestive heart failure means that the heart is still pumping blood‚ but at a slower rate than normal‚ so the pressure in the heart starts to increase as a result. This slower heart rate causes the heart to be unable to pump enough blood to provide the rest of

term mechanism incorporates the release of hormones such as antidiuretic hormone‚ angiotensin 2‚ erythropoietin and aldosterone in attempt to increase blood pressure. The kidneys release renin as a reaction to the decreased renal blood pressure and volume (Martini‚ Ober‚ & Nath‚ 2015). This response results in the activation of angiotensin 1‚ which is converted in the lung capillaries to angiotensin 2 by angiotensin converting enzyme assisting in the control of blood pressure. Erythropoietin is also

Aging and Congestive Heart Failure Rebecca E. Welch What Is Congestive Heart Failure? Congestive Heart Failure‚ also known as CHF‚ is a chronic condition that affects the chambers of your heart. You have four chambers: two atria in the upper half of the heart and two ventricles in the lower half. The ventricles send blood to your organs and tissue and the atria receives the blood as it circulates back from the rest of the body. CHF develops when your ventricles cannot pump in sufficient volume

Instead‚ use the following example for ACE inhibitors: Instead of answering “ACE inhibitors are a group of drugs that treat hypertension‚” ask yourselves: Who is usually prescribed angiotensin-converting enzyme (ACE) inhibitors? Where is the ACE located? When are most prescribed? What medical diagnosis warrants an ACE inhibitor? How do they work? While defining the remainder o/the vocabulary words‚ ask the following questions: Angioedema:

Lab 7: The Kidney’s Role in Fluid Balance Introduction The renal system performs a vital role in homeostasis. The kidneys’ ability to retain valuable constituents and expel metabolic wastes from the body enables this system to regulate the volume‚ osmolarity‚ and pH of body’s internal fluid environment (Sherwood‚ 2007‚ p. 511). The functional unit of the kidney‚ referred to as the nephron‚ is composed of both tubular components—Bowman’s capsule proximal tubule‚ loop of Henle‚ the distal tubule
