Several risk factors can make you more likely to develop lung cancer. smoking is by far the leading risk factor for lung cancer. about 80 percent of lung cancer deaths are thought to result from smoking. the risk for lung cancer among smokers is many times higher than among nonsmokers. the longer you smoke and the more packs a day you smoke, the greater your risk. cigar smoking and pipe smoking are almost as likely to cause lung cancer as cigarette smoking. smoking low-tar or “light” cigarettes increases lung cancer risk as much as regular cigarettes. smoking menthol cigarettes might increase the risk even more since the menthol allows smokers to inhale more deeply. if you don’t smoke, breathing in the smoke of others (called secondhand smoke or environmental tobacco smoke) can increase your risk of developing lung cancer. secondhand smoke is thought to cause more than 7,000 deaths from lung cancer each year.

Muscles in the body us with a lot of things for example, if i wanted to lift a heavy box and had no muscle i would just collapse where i was because of the fact muscles hold us together. overall they are 650 muscle in the human body, all of them have different purposes and ways to keep us together. there are three types of muscle in the body skeletal, smooth, and cardiac muscle. skeletal muscle are attached to the bone and with movement. smooth muscle, this is found in the wall of our organs, such as our stomach, this muscle with movement   as well, without this muscle, we would only be allowed to eat small amounts. the cardiac muscle is the heart muscle and probably the most important one. these are only found in the walls of the heart and the heart pump blood to the other parts of your body. we have two different types of muscle fibers, slow twitch and fast twitch. slow twitch muscles enable long-endurance feats such as distance running. fast twitch fatigue faster but are used in powerful bursts of movements like sprinting. there are three different types of muscle contractions concentric, eccentric, isometric. concentric contraction causes muscles to shorten, thereby generating force.   eccentric contractions cause muscles to elongate in response to a greater opposing force. isometric contractions generate force without changing the length of the muscle.: //athleticquickness.com/muscle-contraction-types-part-1/
