Is Kidney An Organ Or A Tissue. The kidney is an important excretory organ in the body which helps in separating waste matter from the blood stream and purifies blood by helping in passing of urine. A recessed area on the concave border is the renal hilum where the renal artery enters the kidney and the renal vein and ureter leave.

A thin layer of fibrous connective tissue forms the renal capsule surrounding each kidney. The key difference between tissue and organ is that tissue is a collection of cells that serves the same function while organ is a collection of tissues that functions as a unit. Tissues can be repaired by regeneration and fibrosis but as tissues make organs so repair in tissue will result in repair of the organ.
