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

Ions‚ atoms and molecules are constantly in random motion; this is mainly marked in liquids and gases as they are further apart. When there is a small amount of molecules of a substance in an area and a large number is another area and they have no barrier between them the random motion causes numbers to even up; this is called diffusion. Diffusion is when molecules move from a high concentration to a low concentration. The concentration gradient is when the concentration is different for each

P4 – Explain the role of the kidney in the homeostatic control of fluid balance Homeostasis is how our body works to keep the internal environment constant. The kidneys play a role in the control of fluid balance. For this assignment I will be discussing the gross anatomy of the renal system and the kidney. Renal System The renal system is a group of organs that work together to produce‚ store‚ and release urine. It consists of 2 kidneys‚ ureters‚ the urinary bladder‚ urethra and renal vessels which

IV Fluid Balance Assessment 1. According to the reported data‚ my water intake is still short about 100ml/day‚ and the fluid mostly comes from water. In order to prevent the dehydration‚ which might eventually cause coma and death if severe‚ as well as increased burden on kidney and decreased blood electrolyte caused by over-consumption of water‚ the better choices will be juices that are fortified vitamins‚ such as orange juice where usually vitamin A and calcium and some other B-complex vitamins

Case Study: Urinary‚ Fluid & Electrolyte balance The cardiovascular system and the urinary system are intimately entwined. When the cardiovascular system experiences stress‚ the urinary system can be directly impacted. For example in hemorrhagic shock‚ when the body is rapidly depleted of circulating blood volume‚ the kidneys are often one of the first vital organs affected due to lack of perfusion. The kidneys are dependent on the sufficient cardiac output that the heart delivers. So when the

Primary functions of the kidney: — Maintaining homeostasis through the regulation of fluid and electrolytes and removing wastes through the formation of urine. ž Other important functions: — Regulation of acid-base balance — Control of blood pressure — Renal clearance — Regulation of RBC production — Synthesizing vitamin D to the active form — Secreting prostaglandins — Regulating calcium and phosphorus balance. Nephron ž Each kidney has about 1 million

Acid-Base Balance and Fluids and Electrolytes Student’s Name Institutional Affiliation Date Due Respiratory Acidosis Respiratory acidosis refers to a medical defect in which hypoventilation occurs leading to increased concentration of carbon dioxide in the blood and decreased level of pH. Decreased pH in the blood is generally known as acidosis. The body cells continuously respire and release carbon dioxide. The lungs may fail to efficiently expel the CO2. This condition is known as alveolar

The liver converts excess protein into urea. The kidneys remove unwanted substances such as urea‚ excess water and salt. © Boardworks Ltd 2009 What is urea? Excess amino acids in the body are broken down by the liver‚ producing a waste substance called urea. This process is important because it converts toxic ammonia to urea‚ which is done using carbon dioxide. Once formed‚ urea is transported by the circulatory system to the kidneys. The kidneys filter the blood‚ removing urea and excess water

Kidneys * Kidneys maintain the purity and constancy of our in internal fluids. Every day‚ the kidneys filter gallons of fluid from the bloodstream. They then process this filtrate‚ allowing wastes and excess ions to leave the body in urine while returning needed substances to the blood in just the right proportions. Kidneys also regulate the blood’s volume and chemical makeup so that the proper balance between water and salts and between acids and bases is maintained. * The Kidneys alone
