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. If ADH levels increase‚ water reabsorption by the DCT/collecting ducts increases and the resulting

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

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

Our body continually strives to maintain a constant internal environment‚ this balance is called Homeostasis‚ allows the body to function as effectively as possible. b. Reaction to stress. Three stages: Alarm reaction‚ resistance‚ and exhaustion/recovery. i. Alarm reaction‚ the immediate response to a stress‚ the body evokes an instant physiological

A physician assistant is a state license medical professional. Under the physician’s supervision‚ they are trained to examine patients‚ diagnose injuries and diseases‚ and provide treatment. The roles of a physician assistant is to help expand the field of health care. With my field of study being biology‚ I have plans to contribute and serve people while working in health care. The degree of biology will help me set a foundation for graduate school where I will specialize in becoming a PA.

The Muscle System allows moving by contracting and releasing it self as what happens when you flex. Our Nervous system controls the muscle system even though some muscles like cardiac muscle move completely automatically. There are three distinct types of muscles: skeletal muscles‚ cardiac or heart muscles‚ and smooth (non-striated) muscles. Muscles provide strength‚ balance‚ posture‚ movement and heat for the body to keep warm.The Skeletal System is of both fused and separate bones connected and

Tobacco smoke in the body can convert into carcinogens‚ which can lead to lung cancer. Smoking can affect homeostasis by affecting oxygen levels and increasing the levels of carbon dioxide and by affecting the strength of the blood flow in the lungs. It would cause the heart to work harder to pump the blood to the lungs. (McMillan‚
