system to work efficiently delivering oxygen to the muscles for an extended period of time. Walking‚ jogging‚ biking‚ rope jumping‚ aerobics‚ and swimming are examples. Body Composition is the proportion of body fat to lean body mass. Typically‚ activities that help to develop cardiovascular endurance also help to improve body composition. Flexibility is the range of motion through which a joint or sequence of joints can move. The length of muscles‚ tendons‚ and ligaments can be increased through stretching

Pithing and Muscle Preparation. The method for pithing the frog and preparing the frog gastrocnemius muscle will be described by the instructor. The object of the pithing operation is to destroy specified parts of the central nervous system. In this case the frog is pithed as a means of immobilization and anaesthesia. Generally‚ pithing the spinal cord only is adequate. To skin the frog leg‚ cut the skin all around the upper end of the leg. Pull the skin down the leg‚ freeing it from

movement. There are many parts in our body that benefit from exercise‚ but one of the most important parts that exercising helps is the cardiovascular system. For example‚ when you exercise‚ muscles move‚ and to move‚ muscles need oxygen in the blood‚ so the heart has to pump blood in a faster rhythm to keep the muscles moving. This trains your heart and lungs giving you more strength for the future. Which your heart and lungs are mainly what keeps you living. Another part of a person’s life is strong

equate large muscles with strength‚ that is not necessarily so. Strength is not directly proportional to the size of a muscle. First‚ you need to decide which muscles you want to strengthen‚ then find the best way to exercise those muscles so they will respond with increased strength. Then keep increasing the weight load to challenge the muscles. For instance‚ add 1 pound now and another pound in a month‚ and so on. The more you load the muscles‚ the stronger they will become. Muscles respond quickly

stomach has three layers of non-striated muscle in its wall and an inner lining of columnar epithelium with goblet cells. The tissue connecting the lining with the muscular coat is areolar tissue. Non striated muscle is a type of muscle tissue‚ which is also called involuntary‚ smooth or plain muscle. It still contains the protein filaments; they do not lie in an ordered pattern and therefore do not produce the banding characteristics of striated muscle. The muscle fibres are spindle or cigar shaped

keep the muscles activated. To grant this the heart pumps higher frequency of blood increasing the heart rate. Heart pumps blood through arteries faster resulting in a high blood pressure. Exercise increases the stroke volume (the amount of blood pumped in one beat)‚ so an increase in stroke volume means that the heart can pump enough blood to the body with fewer beats per minute. Even after the exercise the heart rate will remain high for some time. The dilation of the active muscles increases

Humans breathe and speak daily without a thought of what really goes into this one aspect of communication. Even though breathing and speaking may seem like a mindless process‚ there are a number of muscles‚ ligaments and body parts that go into the mechanisms that make life what it is. In order to live and speak‚ we must be able to breathe. Respiration is the act of breathing. The act of drawing in a breath‚ or inspiration is the process of in-taking air. Air is taken in through the upper airways
