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

as the Pagos Sea Lion‚ spends a great majority of its day in the water hunting for prey‚ however it does not venture out very far from its territory due to the fact that their main predators tend to be there. Their prey is primarily fish‚ squid‚ octopus‚ and crustaceans‚ and predators are sharks and killer whales‚ but humans are not a threat now. Pursuing this further‚ humans were a prodigious threat previously when sea lions of all kinds were hunted for meat‚ skin‚ and oil. Luckily‚ though hunting

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‚

cell theory‚ gene theory‚ evolution‚ homeostasis‚ and laws of thermodynamics. • Cell Theory: all living organisms are composed of cells. The cell is the basic unit of life. • Gene Theory: traits are inherited through gene transmission. Genes are located on chromosomes and consist of DNA. • Evolution: any genetic change in a population that is inherited over several generations. These changes may be small or large‚ noticeable or not so noticeable. • Homeostasis: ability to maintain a constant internal

Hypertension My name is Jennifer‚ and I am the education nurse here at ITT Internal Medicine. Your doctor asked me to explain to you your diagnosis of hypertension. I will go over what hypertension is‚ how your cardiovascular system works and maintains homeostasis‚ how the rest of your body could be affected by hypertension‚ and what you can do to lower your blood pressure. Hypertension is a chronic medical condition where the pressure of blood in the arteries is elevated. Blood pressure is a measure of

The tidal volume and the rate increased drastically from normal breathing. 10. What might cause a person to hyperventilate? Anxiety‚ fear‚ and even high altitudes with a decrease in oxygen would cause to body to breath faster and deeper to maintain homeostasis. Activity 2b: Hyperventilation – Run 2 1. What

Communication‚ Homeostasis & Energy Communication & Homeostasis Outline the need for communication systems within multicellular organisms‚ with reference to the need to respond to changes in the internal and external environment and to co-ordinate the activities of different organs. Organisms need to respond to external stimuli‚ e.g. temperature‚ oxygen concentration and levels of sunlight. These may be over time‚ e.g. winter fur to summer fur‚ or quickly‚ e.g. changing size of pupils. Internal
