The Kidneys.
The plasma passes through the kidney where it is filtered, a special filtration unit called "glomeruli" and then excreted as a low molecular weighted product into the urine. The purpose of our urine is to secrete waste products from the body. So you can see how the glomerular filtration mechanism of the kidneys plays a major role in the function of our bodies. The primary function of our kidneys is to filter out all the "bad stuff" in lamest terms.

DNA ligase is an enzyme that repairs irregularities or breaks in the backbone of double-stranded DNA molecules. It has important role in the process of DNA replication and DNA repair. It has three general functions: It seals repairs in the DNA, it seals recombination fragments, and it connects Okazaki fragments (small DNA fragments formed during the replication of double-stranded DNA). DNA ligase functions by forming a bond between the end of a “donor” nucleotide and the end of an “acceptor” nucleotide.
