25 The Urinary System: Urinary System Organs * Kidneys are major excretory organs * Urinary bladder is the temporary storage reservoir for urine * Ureters transport urine from the kidneys to the bladder * Urethra transports urine out of the body Kidney Functions * Removal of toxins‚ metabolic wastes‚ and excess ions from the blood * Regulation of blood volume‚ chemical composition‚ and pH Kidney Functions * Gluconeogenesis during prolonged fasting * Endocrine functions * Renin: regulation

The urinary system a very valid and important system though underrated. And why is that‚ we see ads on the TV for dialysis centers‚ kidney stones‚ UTI infections‚ and bladder control issues‚ not to mention bladder cancer. The purpose for this paper is to explain the urinary system. The urinary system is made of two kidneys‚ two ureters‚ two sphincters muscles‚ the bladder and the urethra. The kidneys filter metabolic waste and chemicals from blood to the urine. They do this by filtering units called

A&P II – Test 3 – Rider Urinary System: Q 1. a) What are the different parts of urinary system. The 2 kidneys‚ The 2 ureters‚ the Urinary Bladder and the Urethra. b) What is nephron? Name different parts of a nephron. Write absorption and secretion of different parts of a nephron. Nephron: It is the functional part of the kidney‚ encharged of filtration of blood and eliminates the nitrogenous waste of our bodies. The nephron consists of: functional units; two parts: renal corpuscle

-Contributions to metabolism: The kidneys help synthesize the hormone calcitriol. 2. Kidneys: the kidneys filter out wastes from the blood these wastes are then liquified into urine. Ureters: The ureters funnel the urine into the Urinary Bladder. Urinary Bladder: the urinary bladder stores the urine until muscle contraction forces the urine out. Urethra: the urethra is where the urine is forced out of the body. 3. 4. Renal Capsule: a smooth‚ transparent‚ fibrous

fluctuations in the external environment of that cell or organism. The internal environment is set to function at its optimum rate - and it is dependent on variables such as body temperature‚ blood pressure and blood sugar levels. These need to be maintained despite changes in the external environment as well as the extent of activity and the diet of the organism. These variables are controlled by homeostatic mechanisms. Thermoregulation is an aspect of homeostasis that is the ability of an organism to

The major functions of the urianry system are produces urine‚ stores urine‚and elimintes urine. The organs of the urinary system work to help the body get rid of wastes and excess water in the form of urine. Other urinary system organs help transport urine or store urine and release it when it is time. The organs of the urinary system include the two kidneys‚ two ureters‚ a urinary‚ bladder‚ sphincter‚ and the urethra. The kidneys are two bean-shaped organs‚ each about the size of a fist. They

Chapter 24: The Urinary System Study Guide 1. What are the functions of the urinary system? a. Filter blood to allow toxins‚ metabolic wastes‚ and excess ions to leave body via urination b. Regulate volume and chemical makeup of the blood c. Maintain proper balance between water and salts‚ acids and bases d. Gluconeogenesis during prolonged fasting e. Production of renin to help regulate BP and erythropoietin to stimulate RBC production f. Activation

by the pancreas‚ which produces a hormone known as the insulin; this hormone is able to reduce the blood glucose levels. If there is not enough produced then the disease diabetes is developed. Negative feedback mechanisms: ‘a body system that monitors a system output‚ that shuts off once an optimum output level is achieved and turns on if the output level dropped below optimum’ (reference: Walsh‚ 2010)For example if the body temperature is too hot then it will cool down‚ and if the body temperature

The urinary system consists of two kidneys that filter the blood‚ two ureters‚ a urinary bladder‚ and a urethra to convey waste substances to the outside. 17.2 Kidneys (Fig. 17.2) A. The kidney is a reddish brown‚ bean-shaped organ 12 centimeters long; it is enclosed in a tough‚ fibrous capsule. B. Location of the Kidneys 1. The kidneys are positioned retroperitoneally on either side of the vertebral column between the twelfth
