Kidney: Anatomy and Functions, Labeled Diagram & Importance |
Kidneys
The human body has a pair/couple of kidneys, which consists of millions of functional units/operating-systems called nephrons. The nephrons have extensive/comprehensive blood supply via the renal arteries. The renal vein collects/accumulate blood from each kidney.
Shape
The human kidneys are bean-shaped/fashion/form. Depression in the kidney is called hilus, from where blood vessel leaves and enter the kidney.
Anatomy
The outer/exterior portion of the kidney is called cortex while the inner/interior portion of the kidney is called medulla. On the inner portion of the medulla are renal pyramids. The central/intermediate cavity of the kidney is pelvis.

Functions of kidneys
The function of kidney and blood in clearing wastes is evident from the fact weight of kidney is less than 1% (one percent) of total body weight while receiving 20% (twenty percent) of blood, supplied with each & every cardiac beat.
After filtration of blood and further processing through the tabular system urine is collected in a central cavity of the kidney called the pelvis.
Ureter
Urine quit/leave the kidney through a duct called ureter.Urinary bladder
The ureters of both the kidneys drain urine into the urinary bladder through ureteral orifices.Urethra
Urine quit the body during urination, from the bladder through a tube called urethra.
In human females, urethra empties near the vagina. On the other hand in human males, urethra empties through the penis in males.
