Muscular System: The muscular systems is responsible for maintaining posture, circulating blood, and movement. Visceral muscle is found inside of organs like the stomach, intestines, and blood vessels. The stomach secretes acid and enzymes that digest food. The muscular system also has another variant which is skeletal muscle. The skeletal muscles are attached to bones and move various parts of the body. The biceps, pectoralis major, triceps, nasalis, and deltoid are five major organs in the muscular system. The biceps main job is to control the movement of the elbow and shoulder. The pectoralis major make up most of the chest bulk. The triceps help extend and retract the forearm. The nasalis compress nasal cartilage. The deltoid is responsible…

In the body, these muscles are stimulated to contract by somatic motor nerves that carry signals in the form of nerve impulses from the brain or spinal cord…
As mammals our aerobic metabolic system requires oxygen for us to sustain life. The organ that transports oxygen from the environment into the body where it is needed, are the lungs. Oxygen is transported through cellular respiration from the lungs to tissues and organs. Between 2,100 to 2,400 gallons of air is breathed to fuel 2,400 gallons of blood that is pumped into the heart. Respiration is controlled by the medulla oblongata, which deals with the autonomic function of breathing. This characteristic allows one to breathe without having to think about the process but can also be overridden and controlled in certain situations. As a result of respiration, carbon dioxide is produced where it is removed for oxygen to be restored. The purpose…

Our skeletal muscles make up 40-50% of our total mass and are essential for all humans to move, breath, and stand up straight. For the first 20 years of our lives and for those physically active after our muscles are continually growing. Satellite cells are responsible for this growth in our skeletal muscle and are referred to as muscle stem cells. When skeletal muscle cells are traumatized due to physical trauma or disease the regeneration process includes three general processes, destruction, regeneration and remodeling. What regulates these three processes? How are they signaled to initiate the cell cycle and what nutrients and systems do they require to carry out the processes…

Roux-n-Y gastric bypass surgery is the most common and successful combined weight loss surgery in the United States. For people who are morbidly obese (BMI of 40 or greater) or BMI of 35 or more with serious health issues, the surgery benefits them more then not getting it. It has been said that 95 percent of people who diet to lose weight put it back on within two to three years (Dr. Leibel, 2005). With surgery you have the tool to change this because you will have a smaller stomach which helps prevent so much hunger at least at the beginning. People who are morbidly obese should seriously consider getting this surgery because the pros outweigh the cons by far. A majority of patients having surgery for obesity can expect long term weight loss if they follow all the postoperative guidelines. Gastric bypass has…
