Carbon Dioxide and wastes are transferred for oxygen. The  blood then travels to the left atrium by the pulmonary artery and  then to the left ventricle. The blood leaves the heart by the aorta  to the other parts of the body.. The circulatory system is the organ system that carries substances around our body. There is no such thing as a circulary system.
Overview [edit]. The purpose of the ribosome is to translate messenger RNA (mRNA) to proteins with the aid of tRNA. In eukaryotes, ribosomes can commonly be found in the cytosol of a cell, the endoplasmic reticulum or mRNA, as well as the matrix of the mitochondria.
    The organelle which is the site of protein synthesis for the cell is the ribosome. DNA in the nucleus has the code for building protein, mRNA picks up the code and â¦ brings it to the ribosome where the code is translated into a sequence of amino acids that makes up specific proteins.1 person found this useful.Answered.or the purpose of this questi â¦ on the actual synthesis occurs at the Ribosomes as these are small multiple part cellular machines that interpret (Translate) RNA into the final proteins. This question implies a bound site however and the Ribosomes can be free moving in the cytoplasm of the cell.
