PHYSIOEX 9‚ ACTIVITY #3 Review Questions ACTIVITY #1 1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out the neuron through the K+ leak channels? 2. Explain why increasing extracellular K+ causes the membrane potential to change to a less negative value. How well did the results compare with your predictions? 3. Explain why a change in extracellular Na+ did not significantly alter the membrane potential in the resting neuron? 4. Discuss the relative permeability of the

Increased muscular activity results in a decreased partial pressure of oxygen‚ an increased partial pressure of carbon dioxide‚ a reduced PH‚ and an increased temperature. Consequently as much as 73% of the oxygen picked up by haemoglobin in the lungs is released in skeletal muscles during periods of physical exercise. Utilisation When we inhale air‚ oxygen is transported to the lungs and can be utilised by the body to stay alive. Oxygen is used to produce ATP for energy “the principle energy

utilized defense mechanisms to cope with their situation. Defense mechanisms are unconscious strategies that protect the ego‚ or "I"‚ that are used to distort reality and relieve anxiety and guilt. People often utilize defense mechanisms to protect themselves from being consciously aware of a thought or feeling which they cannot tolerate and to cope with life and unavoidable stress. There are several different types of defense mechanisms. Some of the most commonly used defense mechanisms are repression

“The Effect of Level of Activity on Clothespin Squeezing Amount Question: Does exercising/ resting affect the number of times you can squeeze a clothespin in a minute? Hypothesis: If the person DOES NOT exercise before the task then‚ they will be able to squeeze the clothespin more because not exercising/resting allows the body to relax and there are no buildups of waste products. Biological Explanation: Both the respiratory system and the circulatory system are involved within my experiment

A mechanism is generally defined as any object or system that has a working part or parts. Most often the term suggests tools‚ instruments‚ and machines. But other examples of mechanisms could be the human body and systems like the universe or a city‚ which is composed of parts that work together like parts of a machine. A technical man constantly works with mechanisms and always needs to understand them; what they do‚ what they look like‚ what parts they have‚ and how these parts work together.

Defense Mechanisms Page 1 Defense Mechanisms Connie Evans Axia College Defense Mechanisms Page 2 Defense mechanisms are techniques that a person employs to overcome guilt or anxiety. Denial is one of these mechanisms that are used to protect a person from developing something‚ which a person would rather not acknowledge. Intellectualization is another form of defense mechanisms; a person will analyze and dissect a situation as a detachment technique. Repression

others‚ and in this sense means of transport have played an important role. Nowadays‚ there is a great variety of means of transport and all of them have advantages and disadvantages. When we have to choose a mean of transport we usually take into account distance‚ speed‚ comfort and cost. But I would like to focus the discussion on transport in our cities and the question is: What do you think is better: to use public or private transport? Regarding private transport‚ I think that the car is the king

The Basic Mechanisms of Homeostasis Overview of homeostasis The term homeostasis was first coined by Walter Cannon in 1929 to literally mean ‘steady state’. It describes the dynamic equilibrium by which internal constancy is maintained within set limits by regulation and control. There are many examples of homeostatic control throughout the human body and in other living organisms‚ such as pH‚ pressure‚ and temperature. A concept important to homeostasis is the process of feedback circuits;

For centuries‚ transport become the necessity for human beings to commute from one place to another. As an example‚ from simply walking followed by using animals as their transportation to the moment when vehicles were created clearly shows that transportation has massively evolved. Although both Brunei and Singapore have the same medium of transportation‚ still a huge difference can be spotted between them both. According to The Brunei Times (2013) “Citing statistics‚ the Ministry of Communications
