most important systems in the body is the lymphatic system. One of many functions in the lymphatic system is to cleanse leaked plasma of bacteria and other foreign substances and return it to the blood stream. This also acts as a surveillance system for immune system cells. Another function of the lymphatic system is to stop or slow pathogen entry‚ prevent disease-causing microorganisms from spreading and to strengthen the response of the immune system. Also‚ the lymphatic system protects against

The lymphatic system The lymphatic system belongs to the circulatory system; it consists of a network of lymphatic vessels which carry around fluid which is known as lymph. These carry the fluid towards the heart in different directions. These vessels are spread out the human body.

The Limbic System Most reptiles and lower order organisms only have the “old brain”‚ the evolutionarily oldest part of the brain responsible for vital tasks such as breathing and sleeping‚ whereas higher order organisms have a limbic system. The old brain is comprised of the pons‚ the medulla oblongata‚ the brain stem‚ the thalamus‚ the cerebellum‚ and the reticular formation. The reticular formation is a network inside of the brain stem‚ part of the “old brain” that is essential for arousal (sleeping

Hormones are chemicals in the body produced and secreted in the body that regulate the function of a particular tissue or organ (Bing dictionary). These chemical messengers transfer information from one set of cells to another. Despite many
