Background: As members of the class Amphibia‚ frogs may live some of their adult lives on land‚ but they must return to water to reproduce. Eggs are laid and fertilized in water. On the outside of the frog’s head are two external nares‚ or nostrils; two tympani‚ or eardrums; and two eyes‚ each of which has three lids. The third lid‚ called the nictitating membrane‚ is transparent. Inside the mouth are two internal nares‚ or openings into the nostrils; two vomerine teeth in the middle of the roof

how ADH secretion works in regulating osmolarity. The experiment began when the groups drank the entire solutions and the time was noted for that. Once the experiment was in progress‚ the groups were instructed not to ingest anything until the lab was complete. During the 30 minute waiting periods between voiding there were three tests to perform on the urine samples. The control urine was used for the first set of data and time was measured since last void. The total amount of time to

Spent hormones. 4. Drugs and other foreign substances. Excretion occurs in specialized organs of the body called the excretory organs. There are two excretory organs in human body :- a) Lungs b) Kidneys The lungs are the excretory organ for removing carbon dioxide and excess water. The kidneys are responsible for removing several unwanted substances which include nitrogenous wastes‚ excess water‚ salts‚ toxins‚ hormones and drugs. The Lungs The lungs are where gaseous exchange occurs

1) The functional unit of the kidney is the a- Calyx b- Nephron c- Collecting duct d- Pyramid 2) All of the following are components of the nephron except the: a- Loop of Henle b- Renal corpuscle c- Proximal tubule d- Renal pelvis 3) Plasma proteins are not commonly found in the urine because: a- All proteins are subsequently reabsorbed b- All of the plasma proteins are too large to fit through the filtration slits c- All proteins filtered

and free water clearance. In severe cases‚ a hypertonic infusion such as 3% NaCl is administered intravenously for 36-48 hours or until the lab results shows an improved Na level. (Porth‚ 2009). Physiological action and possible complications: Furosemide works by blocking the absorption of sodium‚ chloride‚ and water from the filtered fluid in the kidney tubules‚ causing a profound increase in the output of urine (diuresis). Common side effects of furosemide include low blood pressure‚ dehydration

LABORATORY REPORT RENAL PHYSIOLOGY INTRODUCTION: The kidneys‚ which maintain the purity and constancy of our internal fluids‚ are perfect examples of homeostatic organs. They regulate the chemical content the pH and osmotic pressure of the blood. 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. Factors that affect urine

bacterium generally originates in the urethra‚ spreads to the bladder and up through the urethras‚ and finally impacts one or both of the kidneys. Pathophysiology One or both kidneys may be involved. The infection extends from the ureter into the kidney‚ involving the renal pelvis and medullary tissue (tubule and interstitial tissue). Purulent exudate fills the kidney pelvis and calyces‚ and the medulla is inflamed. Abscesses and necrosis can be seen in the medulla and may extend through the cortex
