Your 80 year-old great aunt, Persis, was placing a canning jar on the top shelf of her pantry when she stepped awkwardly off the stool and twisted her leg at the hip. She felt a sharp pain in her hip and, after collapsing to the floor, found she could no longer stand. She was taken to the emergency room where an X ray showed that the neck of her femur was fractured. More detailed X ray images revealed reduced bone mass in the head and neck regions of the injured femur, in the ends of other long bones of the body and in the vertebrae. Surgery was necessary to repair the fractured femur and a biopsy of the bone tissue indicated that the composition of the osteoid was normal. Healing of the fractured femur is proceeding slowly.…

She would also have an increased blood supply. During exercise, the blood flow to the active muscles increases to allow for more oxygen and nutrients to be available to those muscles which are using oxygen and available glycogen stores. This increase in blood flow also allows for more waste products to be carried away from those muscles being worked.…
The Musculoskeletal System combines the skeletal system and the muscular system. All of the bones, cartilage, muscles, joints, tendons and ligaments in a person's body compose what is known as the musculoskeletal system. The bones provide the body with a framework, giving it shape and support; they also serve as protection for internal organs such as the lungs and liver. Muscles are fibres that help to make deliberate movement of a body part or involuntary movement within an internal organ possible. Some people view the musculoskeletal system as two body systems in one or two systems that work very closely together, with one being the muscular system and the other being the skeletal system. The bones of the musculoskeletal…
The body is made up of a number of systems that all interlink and produce everything we need in order to survive. Within the body there is the digestive system; the circulatory system, the nervous system, the muscular system, the skeletal system and the reproductive system. These systems are all part of one another and they share organs, tissues and cells and that is how they interlink.…

Skeletal System The skeletal system has five roles. It provides support, protects internal organs, allows your body to move, stores and produces materials that your body needs. Your skelton gives your body its basic shape and provides the support that you need.…
skeletal system is divided into 2 divisions : the AXIAL SKELETON and the APPENDICULAR SKELETON.…
The human heart has four chambers: two ventricles, each of which is a muscular chamber that squeezes blood out of the heart and into the blood vessels, and two atria, each of which is a muscular chamber that drains and then squeezes blood into the ventricles. The two atria reside at the top of the heart; the two ventricles are at the bottom. And, the heart is divided into left and right halves, so there is a left atrium and left ventricle, as well as a right atrium and right ventricle.…

Announcer: I just came from the doctor and I am definitely going to start hiking once a week, and am going to bump up my exercise routine to three times a week. I also need to get to the grocery store to buy some calcium-rich foods.…
Our bodies are supported by the skeletal system which is made up of bones, ligaments and tendons. The skeletal system works with the muscular system to help the body move. It shapes the body and also protects organs. Inside bones we found the Marrow, which is soft, fatty tissue that produces red blood cells, many white blood cell and other immune system cells.…

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.…
