Discussion Heart Rate Our hypothesis stated 1.) The heart rate increases substantially when a person performs a physical activity and 2.) Females have heart rates greater than males’. In this experiment we measured the resting heart rates and exercise heart rates of both the male and females that are in the class. We calculated the results that were taken by each member of each group in the class (6 males and 16 females total). The average resting heart rate for women was 71.8 beats per minute

Heart Rate Experiment Introduction: The heart rate measures the contractions of your heart and is a requirement for life. The heart uses four chambers. The right and left-lower chambers are called ventricles‚ and right and left-upper chambers are called atria. These four chambers complete two cycles that replenish the tissues with oxygen and get oxygen from our lungs. The heart rate is measured in beats/ minute and a “beat” is when the lower chambers are (two ventricles) contract. This

Homeostasis of BP and Heart Rate A normal blood pressure can be identified by having a systolic pressure of around 120 and a diastolic pressure of around 80. This value is expressed as "120/80". A normal heart rate is expressed as the amount of times it beats in a minute; a normal adult heart rate is between 60-100 beats per minute (BPM). There is a relation between these two measurements‚ but they are stimulated by several different circumstances. The blood pressure is mainly affected
