The function of the cardiac system is to pump oxygen rich blood to the organs, tissues, and cells. It also removes carbon dioxide and waste. Endothelial cells, myocytes, smooth muscle cells and fibroblasts are vital and necessary components for the normal function of the circulatory system. Abnormal cell proliferation and regulation in the cardiac system contributes to the development of cardiovascular disease. We offer 7 types of normal animal primary cells in the cardiac cell system; such as cardiac fibroblasts, endothelial cells and smooth muscle cells.
