Article Summary Effects of earthworms on soil Earthworm is the common name for the largest members of Oligochaeta in the phylum Annelida. They combine bilateral symmetry and corresponding external and internal segmentation. This phylum consists of more than 17‚000 modern species of worms including earthworms‚ ragworms‚ and leeches. They are found in marine environments from tidal zones to hydrothermal vents‚ in fresh water‚ and in most terrestrial environments. They generally do not occur

1. Thermoreceptors perceive the impact of heat on the part of human body and send signals through neurons to brain that causes the feeling of pain. If the signals fail to pass from thermoreceptors to brain‚ the risk of burning the part of the body arises. The pain is the indicator of the danger to human body and the ultimate manifestation of pain is a pain shock‚ which may be deadly for human body. 2. Olfaction is responsible for smell sense. Gustation is responsible for taste. They involve chemical

Homeostasis in the Human Body Homeostasis is the maintenance of a stable internal environment within tolerance limits‚ this is the restricted range of conditions where cellular operations effectively work at a consistent rate and maintain life. These conditions include temperature‚ blood glucose levels‚ pupil diameter control and many more. The body is made up of many cells. Many specialized cells group up to form a tissue. Tissues group up to form organs‚ these organs can then connect to form

importance of the Respiratory system is quite obvious given that as human beings we need this system to help us with our most fatal tasks of breathing. Although the importance is assumed and acknowledged‚ many do not really get the whole concept of the Respiratory system. For example‚ how it works? Why it works? And what all is involved. These questions and others will be strategically answered in the following work. The Respiratory System delivers oxygen to the body and takes the carbon dioxide

The musculoskeletal system is made up of bones‚ joints‚ and muscles. This system gives the body form and support‚ and protects the body while allowing it to move. Basically‚ the muscles in this system perform three important body functions: the movement of body parts‚ maintenance of body parts‚ and production of body heat. These muscles all consist of a mass of protein fibers grouped together‚ and most are of mesodermal origin. And almost all of the muscle fibers you will ever have or need were

Introduction to the Human Body Matching: Directions of the body Medial: Toward the midline of the body; opposite of lateral. Proximal: A structure is nearer to the trunk than is another part; opposite of distal. Distal: The part of the radius (arm bone) that is closer to the wrist than the elbow. Superior: The lung is above the diaphragm; above is described as… Anterior: Toward the front (the belly surface); another word is ventral. Matching: regional Terms Axillary: Armpit. Patellar: Kneecap
