Jessica L. Gillette December 7‚ 2010 Bio 100 Dr. Valentine Homeostasis and Sleep According to Krogh (2009)‚ homeostasis is the maintenence of a relatively normal internal environment. This means that the body has many systems in place to regulate what happens in our bodies to keep it functioning properly. There are very few functions that we have control over in the homeostatic processes ’ of our bodies. Sleep is one of them. Sleep is very important to the regulation of the body ’s functions

1. In physics and chemistry‚ heat is energy transferred from one body to another by thermal interactions. The transfer of energy can occur in a variety of ways‚ among them conduction‚radiation‚ and convection. The SI unit of heat is the joule. Heat can be measured by calorimeter‚ or determined indirectly by calculations based on other quantities‚ relying for instance on the first law of thermodynamics. In calorimeter‚ the concepts of latent heat and of sensible heat are used. Latent heat produces

“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

Physiology mean? Physiology is the scientific discipline that deals with the processes or functions of living things. It focuses on how organisms carry out the chemical or physical functions that exist in a living system. 3. What does Homeostasis mean? Homeostasis is the tendency of an organism or a cell to regulate its internal conditions‚ usually by a system of feedback controls‚ so as to stabilize health and functioning‚ regardless of the outside changing conditions. 4. What are the characteristics

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.

A person who decides to sunbathe without sunscreen all summer runs a high risk of contracting melanoma‚ due to the amount of UV rays they are receiving. Topic 3 Homeostasis is the desired balance of all the vital signs of the body in order to keep the body functioning correctly. It is important to have a “command center” to monitor this information in order to maintain this balance. The brain is the command center
