Effect of spaceflight on the human body for the astronauts. These joint torques and muscle forces could be used in conjunction with more fundamental computational simulations of bone remodeling and muscle adaptation in order to more completely model the end effects of such countermeasures, and determine whether a proposed exercise regime would be sufficient to sustain astronaut musculoskeletal health. The second effect of weightlessness takes place in human fluids. The body is made up of 60% water, much of it intra-vascular and inter-cellular. Within a few moments of entering a microgravity environment, fluid is immediately re-distributed to the upper body resulting in bulging neck veins, puffy face
Exploratory surgery exploratory surgery, is not used for treatment at all. Instead, it is used chiefly to identify the location of the tumor and the extent of its damage. If a tumor is found, a biopsy is performed and tests are run to see what type of cancer was found. Because animals cannot voice their symptoms as easily as humans, exploratory surgery is more common in animals. Exploratory surgery is done when looking for a foreign body that may be lodged in the animal's body, when looking for cancer, or when looking for various other gastrointestinal problems. It is a fairly routine
