Brown meat high endurance, lots of mitochondria and myoglobin, appears dark, found legs and wings chicken. Mitochondria exists large amounts in liver, heart, skeletal muscle. Cell theory cells structural building blocks plants & animals, produced by pre-existing cells dividing, smallest structural units preform all vital f(x)"s. 4 primary tissue types epithelial, connective, muscle, neutral: epithelial tissue barrier, lines everything inside & outside, secretions. All organ systems interrelated, work together maintain homeostasis. Red marrow decrease as get older replaced by yellow marrow. In human body, glycogen = storage form glucose: very quick energy source, when exercise drawing from glycogen reserve. Most homeostatic processes in body = negative feedback: all homeostatic mechanisms receptor, control center, effector. Set point for body temp 37. 2 deg celcius. + feedback rare body, doe not restore homeostasis, ex : child birth, process guided by oxytocin.
