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.
Related Information: They do this by translating messenger RNA (mRNA) into proteins. Messenger RNA is simply a copy of the DNA from the nucleus that is allowed to enter the cytoplasm and be used to make proteins. Ribosomes are the sites of protein synthesis, where RNA is translated into protein.When cells need large numbers of proteins, they must first build numerous ribosomes. Because protein synthesis is so important to cells, there are large numbers of ribosomes in all cells, often numbering in the hundreds or thousands.ibosomes make proteins for use in the cell and for export. a ribosome is a part of the cell in the animal They make the amount of protein needed for the cell.
