“Common biochemical themes are important to understanding cell injury and cell death regardless of the injuring agent” (Heuther & McCance‚ 2012). Cellular injury arises when a cell is unable to sustain homeostasis. The injury can be reversed if the cell can recover from whatever damage was done but if it does not recover the cell will die. The three common forms of cell injury are hypoxic injury‚ free radicals and reactive oxygen species injury‚ and chemical injury. The most common form of cell

Cone cells provide color vision. Cones give humans sharper colors. Rod cells are found on the side while cones are found on the bottom. 3. Explain how the body maintains homeostasis of serum (blood calcium) levels through the use of the thyroid and parathyroid gland. The body maintains homeostasis of serum levels through the use of the thyroid and parathyroid glands because the thyroid secretes calcitonin and the parathyroid secretes parathyroid hormone. Both of these hormones

Case Study #3 1. Out of the three time points‚ Max was the most dehydrated immediately after exercise. 2. The two parameters that can be used to determine Max’s hydration status is color and and pH. It is not specific gravity (SG) because Max’s SG is 1.035 which is within normal range. It is also not protein because in the lab manual it says that a trace amount of albumin in Max’s urine is normal. 3.
