The systems cannot work by themselves as they both provide the materials needed throughout the body. They supply energy to all the cells throughout the body. The respiratory system and digestive

the certified tumor registrar (CTR). A cancer registry is a compilation of all cancer related data on all cancer patients‚ including their demographics‚ medical histories‚ diagnostic findings‚ and follow up assessments. This information provides health care professionals with the necessary data and tools to successfully develop‚ implement‚ assess and evaluate current and future treatments and therapies for the overall goal of preventing and controlling cancer (NCRA‚ 2002). The registry is also a key

The characteristics of a healthy cell and a cancer cell is very different. Healthy cells stop reproducing when there are enough cells‚ however‚ cancer cells continue to reproduce. Due to this continued growth a tumor‚ which is a cluster of cancer cells‚ is formed. Cancer cells do not interact with other cells like the healthy cells. Healthy cells stop growing when they hear signals from the nearby cells‚ in contrast‚ cancer cells do not respond to these signals. When healthy cells get old or damaged
