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

Biology exam Endocrine system: Hormones: chemical messengers that coordinate the body’s activates. Substances secreted by cells that act to regulate the activity of other cells in the body. They are part of the endocrine system and they are slow acting but have a longer affect than neurotransmitters. Functions: * regulate growth‚ development‚ behavior‚ and reproduction. * Maintain homeostasis * Regulate metabolism and water and mineral balance * Respond to external stimuli

* Trivia: Other terms used to refer to the "Urinary System" include the "Renal System" and the "Genito-urinary System" * Important Functions of Urinary System *Besides removing waste from bloodstream‚ the urinary system preforms several other functions as well. They are as follows: * Storage of Urine: Urine is producing all the time‚ but it would be inconvenient if we were constantly excreting urine. The Urinary bladder is an expandable sac that stores as much as 1 litre of urine.

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

of Urinary System The urinary system consists of the kidneys‚ ureters‚ urinary bladder‚ and urethra. The kidneys filter the blood to remove wastes and produce urine. The ureters‚ urinary bladder‚ and urethra together form the urinary tract‚ which acts as a plumbing system to drain urine from the kidneys‚ store it‚ and then release it during urination. Besides filtering and eliminating wastes from the body‚ the urinary system also maintains the homeostasis of water‚ ions‚ pH‚ blood pressure‚ calcium

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

The autonomic nervous system stimulates _Skeletal___ muscle‚ __Cardiac___ muscle‚ and _Glands___. 2. The autonomic nervous system (ANS) consists two divisions‚ each innervating the effector organs. The sympathetic nervous system (SNS) generally speeds up everything except digestion. The parasympathetic nervous system (PNS) generally slows down everything

Lymphatic system Lymphatic capillaries-Absorb excess tissue fluid and return it to the blood stream Lacteals (in small intestine) –absorb fats vin the form lipoproteins and transport them to the bloodstream Lymphoid organs lymphatic vessels are sites of production and distribution of lymphocytes‚ which help defend the body against pathogens Lymphatic vessels One- way system-The movement of fluid is dependent upon skeletal muscle contraction; when the muscles contract‚ fluid is squeezed past

-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
