The thymus is an organ composed of two lobes and is located directly in front of the heart and behind the sternum. It is a critical part of the immune system because it trains and modifies T cells that are used by the body to fight foreign materials that can cause sickness.
Marketing managers typically have a bachelor's degree in marketing or business administration; however, some employers may prefer a master's degree, in addition to extensive experience in marketing, advertising, brand management or sales.
A bachelor's degree in marketing will prepare you for entry-level positions in all areas of marketing, from creative roles--such as media design and copywriting--to market research and analysis. Depending on your interests, you could work in sales, account management, insurance, purchasing, advertising or research.
