Introductory Activity Heart Rate (pulse) Have the students find their heart pulse on the carotid artery of the neck. Use the index and middle finger to measure the pulse. Count the number of beats for 6 seconds and add a zero to the end of that number. This number represents the heart beats per minute. The heart pulse is located on either side of the wind pipe‚ next to the voice box. Allow the students to practice measuring their pulse to determine their resting heart rate. Explain that they need

1. The heart rate determines the intensity of the fitness activity. a. 12*6=72 b. 220-21=199 c. 129-150 range. 2. Aerobic metabolism‚ uses fats‚ proteins and carbohydrates that are oxidized and turned into carbon dioxide and water. Anaerobic metabolism‚ uses only carbohydrates and enters the fluid‚ or cytoplasm‚ of the cell and is turned into lactic acid. Aerobic exercises are running‚ biking‚ and swimming‚ whereas anaerobic exercises are sprinting‚ jumping‚ weight training. 3. My activity is considered

The Effect of Position on Heart Rate This lab explores the effect of head position on an individual’s heart rate by having a subject move it’s head while simultaneously monitoring the subjects heart rate. There were three successive periods during which the heart rate was monitored that occurred in this order: a resting stage (subject sitting upright)‚ a stage with the head positioned between the knees‚ and a recovery stage (subject returns to upright position). The graph depicts a wide range

Heart Rate Anticipatory Response: Anticipatory heart rate is the rate that the heart reaches before the start of exercise. Your heart rate usually picks up as a result of the anticipatory heart-rate response‚ this happens before exercise. When thinking about exercising before actually starting‚ the nerves that release the chemicals that adjust your heart rate increase the heart rate. The body expects exercise and therefore prepares for the activity‚ increasing the amount of oxygen being delivered
Premium Blood Heart Artery
Every day your heart pumps blood through a vast network of blood vessels around and around your body‚ delivering food and oxygen to cells and removing waste. The pulse (heart rate) is the number of times a person’s heart beats per minute (bpm). The pulse is a rhythmical throbbing of the arteries as blood is propelled through them‚ typically felt in the wrists or neck. Your resting heart rate occurs when you become relaxed or comfortable. These are shown when sitting or lying down. The ability to

Temperature and Epinephrine on The Heart Rate of Daphnia Leslie Orzetti-Gollhofer Gaby Macias INTRODUCTION The Daphnia is a Crustacean other known as the water flea. It lives in small bodies of freshwater. The Daphnia is ectothermic‚ meaning it controls its body temperature through external means. With this experiment we experienced first hand what the effect temperature has on a Daphnia’s heart rate. We also experimented what effect epinephrine has on a Daphnia’s heart rate. HYPOTHESIS If we add hot

Effects of salinity on the survival of the Daphnia Introduction The Daphniidae daphnia is a freshwater crustacean from the branchiopod class that is common to most ponds‚ lakes‚ pools‚ streams and springs around the world. The water flea‚ as it is sometimes referred to‚ is very small in size growing to a length of less than ¼ inch‚ it has a flat back‚ a rounded belly‚ black round eyes and a pair of antennae (Kindersley‚ 2006). The Daphnia have leaf-like appendages used in respiration‚ filter

1-1 EXPERIMENT 1 ISOLATION OF CAFFEINE FROM TEA In this experiment you will isolate caffeine from tea leaves and prepare the salicylate derivative. Introduction This experiment illustrates the isolation of a naturally occurring product from plant material -- caffeine from tea leaves. The experiment will provide experience in handling relatively small amounts of material and at the same time you will be exposed to several techniques and procedures which are fundamental for survival in an organic

information Daphnia Magna is an arthropod that can grow up to 5 mm. It is a filter feeder meaning it feeds off of suspended particles in the water. Daphnia can consume particles that range from 1µ to 50µ. The heart of Daphnia is located dorsally meaning it’s located in the back. The heart rate of Daphnia can range due to many variables‚ one being temperature. "At a temperature averaging 20o C its heart rate is about 200 beats per minute."2 As the temperature surrounding the Daphnia decreases so
