Dermal fibroblast ECM which organizes the stratified squamous epithelial cells of the epidermis into a unified tissue. Furthermore, dermal fibroblasts create long fibrous bands of connective tissue which anchor the skin to the fascia of the body. Therefore, without dermal fibroblasts, the largest and heaviest organ would not tightly adhere to body's frame. Since dermal fibroblasts play a critical role in wound healing, researchers are attempting to generate mature dermal fibroblasts to repair second and third degree burns. When the body sustains a third degree burn, the skin's dermal layer is completely destroyed by heat (and the all fibroblast cells within the
Effect of spaceflight on the human body such a design, pressurization of the torso could be achieved mechanically, avoiding mobility reduction associated with pneumatic pressurization. Human physiology is adapted to living within the atmosphere of Earth, and a certain amount of oxygen is required in the air we breathe. If the body does not get enough oxygen, then the astronaut is at risk of becoming unconscious and dying from hypoxia. In the vacuum of space, gas exchange in the lungs continues as normal but results in the removal of all gases, including oxygen, from the bloodstream. After 9 to 12 seconds, the deoxygenated blood reaches the brain,
