Excretory system:The excretory system is a group of organs that facilitate the elimination of waste products produced by the cells after cell metabolism

Substances that are released

Urea and uric acid:Formed whem the body break down proteins and nucleic acids

Toxic substances: these have to be injested.Examples: drugs alcohol and medicines

Carbon dioxide: formed during the metabolic reactions that produce energy

GROUP OF ORGANS: LIVER, SWEET GLANDS, RESPIRATORY SYSTEM AND URINARY SYSTEM that facilitate the elimination of waste products produced by cells after cell metabolism. Participates in the body’s HOMESOTASIS (regulate the quantity of wáter in tissues, the concéntrate of minerals and the blood’s pH


Urinary system: is formed by two organs: the kidneys and the urinary tract

Kidneys: they are two bean shapped organs that are located behind the abdomen, each one has an internal section that is called the renal cortex, an internal section called renal medulla and a cavit nkown as the renal pelvis that collect urine

Urinary tract: they are the exit chanels for urine they conect the kidneys to the exterior

bowman capsule: it is a capilary that folds into a ball called the glomerulus of Malpighi

convuted tube: it is a tube that have two main parts: proximal and distance

They are tubes whith one close end and are surronded by blood capylaries, they are tyhe responsibles of filtring blood and creating the urine

loop of henle:It is a section located beetween convuleed and the distal one

Other functions of the kidneys

they actively intrervene in the regulation of the internal enviroment

they secrete substances that stimulatd the creation of red blood cells

ureter: they are thin tubesthat start from each kidney and in the end of the bladder in an elastic bag where urine is accumulated

Urethra: is the duct that connects whith the exterior. A man erethra is conected whith the reproductive system and woman urethr is indemendent from the reproductive system

Urine formation: the function of the kidneys is to create urine and to released it to the exterior

urine: is a liquid obteined from blood composed of water, minerals and diverse products

Proceses

Glomerular filtration: this consist on the passage of certein substances from the blood contained in the Malpighiam glomerulus passage to the intirior of the bowmans capsule, As a resul water and more substances are filtred and pass to the plasma
