Urinary
The excretory system is a set of bodies responsible for the elimination of nitrogenous waste products of metabolism, known in medicine as urine that comprise the urea and creatinine. Itsarchitecture consists of structures that filter body fluids (liquid celomático, hemolymph, blood). In invertebrates, the basic unit of filtration is the nephridia, while in vertebrates is nephrons ornephron. The human urinary system consists basically of two parts:
The secretory organs: kidneys that produce urine and carry out other functions.
Excretory, which collects urine and expels itoutside.
It consists of a set of tubes that are:
The ureters carry urine from the kidneys to the bladder. The urinary bladder, receptacle where urine collects.
The urethra, the tube that carries urineto the outside, being short in length in women and longest man called penile urethra.
Structure
1.Zona cortex or bark: Located on the outside and bright red.
2.Zona core: Occupies the inside,dark red, consisting of 10 to 18 triangular formations called malpighian pyramids.
Urinary tract
Two ureters
They are tubes that measure approx. 25cm, and about 3 or 4 millimeters diametro.Estosducts carry urine from the kidneys to the bladder.
The bladder
One of the main organs of the excretory system. It is located in the pelvis.
The bladder is a muscular bag which is responsiblefor storing and releasing urine.
Receive the urine by the ureters, which open in the back of the bladder, when empty the bladder can be almost as small takes the size of a plum, when filled, butcan have size a grapefruit. has a great capacity to expand, as though it may contain between 200-300 ml before a person to notice the sensation to urinate.
At the base, the bladder opens into theurethra, the tube that carries urine out of the opening and closing thereof is controlled by the esfinter.esta is the last phase of the excretory system
