Iker Lopez Anatomy & Physiology P2 Wednesday‚ September 19‚ 2012 Heart Rate Response to Baroreceptor Feedback Lab Fundamental Question: Does the body respond to its environment? Testable Question: When the body is in the squat position to normal while the time limit stays the same and how far you squat is the same‚ will the heart rate recover after returning to standing position in 10 seconds? Hypothesis: If the body moves back to normal position from squatting position while the time limit

as the mammalian dive reflex. During this reflex bradycardia‚ a slowing of the heart rate‚ is shown. In this study‚ human subjects were put through various tests to determine if humans also exhibit bradycardia. Subject’s heart rates were measured while breathing normally‚ while holding breath and while holding breath with face submerged in water. The results showed that there was a significant decrease in heart rate while submerged in water as compared to normal breathing or holding breath out

help us determine the electrical activity of the heart. As well as‚ to observe how exercise and different body positions(conditions) can affect the activity of the heart. Introduction Trained professionals can look at the EKG tracing and determine if the heart is normal or if the heart is abnormal. “An ECG records the electrical activity of the heart. The heart produces tiny electrical impulses which spread through the heart muscle to make the heart contract” (Kenny‚ 2015). There are two different

lessened risk of coronary heart disease – the number one killer in our society. Cardiovascular fitness is also referred to as cardiovascular endurance‚ cardio-respiratory capacity and circulatory fitness. Regardless of the word used to describe it‚ cardiovascular fitness is complex because it requires fitness of several body systems. Physical activity that leads to improved cardiovascular fitness has dramatic health and wellness benefits that extend well beyond heart disease risk reduction. It

I got behind‚ so I need to catch up. Section 2: Target Heart Rate My resting heart rate is 70 bpm. My target heart rate zone is 125 bpm to 167 bpm. Heart Rate Reflection Question: Were you able to maintain your workouts within your calculated target heart rate zone? Explain which activities you enjoyed most and which best helped you stay in your THR zone. Answer: With some of the workouts I was able to maintain my target heart rate zone‚ and the activities I liked the most was the sit and reach

through cellular respiration‚ and in turn‚ an athlete would heighten the intensity of the workout for a longer period of time becoming a better athlete. The VO2 Max of a person can be affected by mass‚ time it took to walk necessary distance‚ and heart rate. Each variable is in turn varied be age and gender. The greater the value for VO2 Max the greater the efficiency of the cardiovascular system. VO2 max plays a major role in the aerobic energy system because an increased VO2 max permits more oxygen

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 does its heart rate. Daphnia has a transparent body which allows one to see its organs. This is why Daphnia is often used in experiments dealing with heart rate. Daphnia inhibits regions
