hormone. Diabetes insipidus doesn’t produce enough ADH or respond to it‚ thus produces too much urine. SIADH is the opposite and retains too much water‚ rather than excreting it excessively in DI. 8. Polyuria-sickle cell diseases‚ pyelonephritis. Polydipsia-Diabetes Insipidus and other conditions that create water deficit. Other commons causes are: 9. DDVAP is a synthetic analogue of the natural pituitary hormone 8-arginine vasopressin (ADH)‚ an antidiuretic hormone affecting renal water conservation

Kharishma Patel BIO 3422-E Urine Analysis Lab Objective The objective of this experiment shall be to examine the effects of different types of fluids on the renal system including rate of urine production‚ pH‚ and specific gravity. Hypothesis The group drinking water will have the highest rate of urine production. The group that drinks water only when thirsty will have the lowest rate of urine production. The specific gravity of urine for all treatment groups will be around 1.000. The pH for

Urinary System: Anatomy Review 1. Name the organs in the urinary system: 1. 2 kidneys 2. 2 ureters 3. bladder 4. uethra 2. The kidneys are retroperitoneal (behind the peritoneum)‚ lying against the dorsal body wall in the upper abdomen. 3. The adrenal gland sits atop the kidneys. Blood vessels enter and leave the kidney at the renal cortex. 4. The functional units of the kidney are the nephrons. They are called renal pyramids if they are located mainly in the cortex. They are called renal

Title: Homeostasis Date: 19th January 2010 Aim: To observe‚ draw and label the parts of a nephron. Apparatus: Slide of the transverse section of a kidney Pencil Paper Microscope Method: The slide of the transverse section of a kidney was mounted on the microscope and observed under high power. Drawings of the parts of the nephron were made. Calculations of Magnification: Loop of Henle One Ocular Division = 0.22 µm Size of Specimen = 2 ocular divisions Conversion of Ocular

damage to the pituitary gland‚ which disrupts the normal storage and release of ADH. Damage to the pituitary gland can be caused by different diseases as well as by head injuries‚ neurosurgery‚ or genetic disorders.” (Medicinenet‚ 2012). The can be treated with the hormone desmopressin. “Nephrogenic diabetes insipidus results when the kidneys are unable to respond to ADH. The kidneys ’ ability to respond to ADH can be impaired by drugs- like lithium‚ for

Unit 2 – Fluid and Electrolyte Imbalance A. Homeostasis a. State of equilibrium in the body b. Naturally maintained by adaptive responses c. Body fluids and electrolytes are maintained within narrow limits B. Water content of the body i. Varies with age‚ gender‚ body mass 1. Men have more muscle mass → increased water‚ fat cells have less water content b. 50-60% of the weight in an adult c. 45-55% in older adults d. 70-80% in infants C. Body Fluid Components a. ICF b. ECF i. Intravascular

Fluid and Electrolytes Imbalances Fluid Compartments: * Extracellular Fluid (ECF) – This is fluid found outside of the cells and the amount of ECF decreases with age. In the newborn for example‚ approximately ½ of the body fluid is contained in the ECF. By the time the infant has reached one year old; the ECF has decreased to approximately 1/3 of the total volume. In an average 70 kg adult the ECF is approximately 15 liters of total volume. ECF can further be divided into the following:

½Give an account of the structure and properties of Biological membranes. Include details of the modifications of membrane structure found in different specialised cells and organelles½ The Fluid Mosaic model was codified by Singer and Nicolson in 1972. It describes the structure and properties of the cell membrane very simply. Every membrane consists of a Phospholipid bilayer. This is simply two layers of phospholipid molecules that come together due to their unique properties. The heads of the
