Measurement of Heart Rate for Autonomic Nervous System Abstract: The Autonomic Nervous System lab was designed to measure reaction times by using a variety of tests that affect the heart rate. These tests were the startle‚ stroop‚ Valsalva maneuver‚ diving reflex‚ and a test of our choice. The test our group chose to measure the heart rate in response to doing a trust fall to anticipate the stress right before the fall. To begin this lab we chose a participant‚ and then hooked their finger

Arrhythmias Arrhythmias are any change from the normal sequence of the electrical impulses in the heart. An arrhythmia is when your heart cannot pump blood effectively. It may happen to fast‚ to slowly‚ or it may happen erratically. When arrhythmias occur; the lungs‚ brain‚ and other organs cannot work properly and they may shut down and be damaged. A normal heart beat is strong‚ muscular pump that is a little larger than a fist and pumps blood continuously through the circulatory system. Arrhythmias

The title should clearly identify the experiment’s variables (independent & dependent) Purpose/Problem: This is the place to explain what you are trying to find out or what you are going to do in the lab. Include information about the variables involved. Hypothesis: “If………then………because………” This is a cause/effect statement. This is a prediction of what the expected outcome of

Coronary arteries supply the heart with a constant supply of blood. These arteries are essential‚ providing oxygen and nutrients that keep the heart constantly pumping. Arteries have three layers including the external layer‚ tunica external‚ middle layer‚ tunica media and the inner layer‚ called the tunica intima. The outer layer is made up of connective tissue with elastic and collagenous fibers. Tunica media is the thickest layer composed of smooth muscle and can change the diameter of the arteries

Injected Reagents on Frog Hearts Melissa Higdon Section 05‚ Group 01 November 19‚ 2013 Introduction: The heart is a very complex muscle for all species. It is responsible for sending oxygenated blood throughout the body as well as sending deoxygenated blood to the lungs‚ and continuously circulate this way for as long as we are alive. Many things can be effected‚ for example how fast the heart beats or how much force the heart chambers contract with

girls and boys heart rates rose slightly with light exercise (walking)‚ and then fell again slightly back towards the original resting point. Then during the period of anticipation of exercise the males heart rate rose by a further 1 beat per 6 seconds‚ whereas the females took a dramatic leap‚ and rose by 3.5 beats per 6 seconds‚ or 35 beats per minute. Then for the exercise period the males rose by nearly 4 beats per 6 seconds‚ or 40 beats per minute. Whereas the females heart rate only rose by 3

Introduction: The human heart rate can change depending on many variables‚ one such variable is the body’s reaction to certain types of food. Wasabi is an excellent example of a food type that incites a reaction‚ as anyone who’s ever eaten it before would agree. This reaction could best be described as agony when not diluted with other flavors. The irritating compounds in wasabi (isothiocyanates) are volatile which means they rise up the roof of the mouth and go towards the nose (Why Wasabi Bites

Electrodermal Lab Report Introduction: The word polygraph translates to “many measures” although many assume it’s a synonym for lie detector. The polygraph records changes from a person’s normal heart rate‚ respiration rate‚ and electro-dermal activity (EDA). Based on these changes which are recorded‚ an examiner can detect if a person is being truthful or lying. The physiological basis of the EDA is that sweat glands will increase secretion based on somatic sensory stimulus‚ for example touch
