briefly describe the functions and the structure of human urinary system in 60 to 80 words
Answers
Explanation:
The urinary system, also known as the renal system or urinary tract, consists of the kidneys, ureters, bladder, and the urethra. The purpose of the urinary system is to eliminate waste from the body, regulate blood volume and blood pressure, control levels of electrolytes and metabolites, and regulate blood pH. The urinary tract is the body's drainage system for the eventual removal of urine.[1] The kidneys have an extensive blood supply via the renal arteries which leave the kidneys via the renal vein. Each kidney consists of functional units called nephrons. Following filtration of blood and further processing, wastes (in the form of urine) exit the kidney via the ureters, tubes made of smooth muscle fibres that propel urine towards the urinary bladder, where it is stored and subsequently expelled from the body by urination (voiding). The female and male urinary system are very similar, differing only in the length of the urethra.[2]
components:
kidney ( nephrons)
ureter
urinary bladder
urethra
the blood enters kidneys and gets purified there through nephrons. the urine is produced here. the urine then passes through the ureter and is stored in the urinary bladder. the muscles of the bladder expand which gives us the urge to urinate. we urinate through the urethra.
