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
