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.
These  organelles are the nucleus, ribosomes, rough endoplasmic reticulum,  and the Golgi apparatus. Proteins are t â¦ he large complex molecules,  which all your cells are making continuously. Each protein is made  up of many amino acids which must join together in a correct order  for the protein to work properly.First it takes the copy of  relevant DNA instruction in the nucleus cell and takes it into  cytoplasm.n cells, protein is produced in the ribosomes. The instructions for protein synthesis are found in the DNA, which is copied onto mRNA. This mRNA then carries these instruct â¦ ions to the ribosomes where protein synthesis occurs. 2 people found this useful.
