Ebola Virus— What type of virus is it? How it spreads? What is being done to contain its spread? What treatments are available? Ebola genome is a single-stranded RNA approximately 19‚000 nucleotides long. It encodes seven structural proteins such as nucleoprotein‚ polymerase cofactor‚ transcription activator‚ RNA- dependent RNA polymerase. The Ebola virus is a Filovirus. These virus types cause fever or cause bleeding inside and outside the body when having a very high fever. Ebola

Structure and Function of the Human Digestive System By Caitlin Ong Organs of the Digestive System Mouth Structure: The mouth consists of the upper and lower jaw‚ that contain gums which hold teeth‚ the roof of the mouth is the palate and the tongue occupies the floor of the mouth. The salivary glands have ducts that open in the mouth. Function: The mouth is where the first step of digestion begins. Known as mechanical digestion‚ this involves chewing with your teeth to break the food

With reference to acid-base balance explore the role of the respiratory system in maintaining blood pH? ‘We live and die at the cellular level’ (Reid‚ 2011). Homeostasis is crucial for normal cellular function. Acid-base homeostasis is the part of human homeostasis and refers to the balance between the production and elimination of H+ hydrogen ions (pH) within the body fluids (William‚ Simpkins‚ 2001‚ p.236).

forcefully‚ this effect makes most of the arterioles to constrict and some arterioles dilate‚ which leads to an increase blood supply where needed. In order to increase blood it is vital for the sympathetic division to get the kidneys to decrease their secretion of salt and water; this will mean an increase in blood volume and blood pressure then returns to normal. Blood pressure can be lowered by the actions of artrial natriutretic peptide (ANP) hormone. Atrial natrriuretic hormones are a protein and a

Parotid glands- lie anterior to the ears. Mumps- a common childhood disease‚ is an inflammation of the parotid glands. * Submandibular glands and Sublingual glands empty their secretion into the floor of the mouth through tiny ducts. * Saliva is a mixture of mucus and serous fluids. The mucus moistens and helps to bind

Some factors that decrease the release of GH include; carbohydrate-rich diet‚ obesity‚ free fatty acids‚ and increased serum glucose level (Adams and Koch‚ 2009). Thyroid-stimulating hormone (TH) controls the secretion of thyroid hormones and targets the thyroid gland. TH is a peptide hormone. Thyroid hormone is produced in the thyroid. It is stimulated by the thyroid-stimulating hormone from the thyroid gland and inhibition occurs when there is negative feedback

Ancillary drugs used in surgery Ancillary drugs are drugs that are used in conjunction with general anaesthetics. Although termed as ancillary drugs‚ these drugs play an integral role in every surgical operation. Ancillary drugs serve multiple functions in surgery and can enhance the surgical procedure and patient safety. To most patients‚ the prospect of an impending surgical operation leads to preoperative anxiety‚ especially given that the outcome of the surgery is unpredictable (Valenzuela
