High or Low Blood Pressure? Purpose: The purpose of this experiment is to compare blood pressure as related to gender and athletic status. Hypothesis: I predict that males have a higher blood pressure than women and athletes have a higher blood pressure than non athletes Background Info: Blood pressure is the amount of force that blood pushes against the inside walls of blood vessels as it passes through. This pressure

Daphnia Heart Rate Background: In the world today‚ there are many chemicals that people use to fix or help with issues within their own bodies. Some of these chemicals may include things like caffeine‚ nicotine‚ and alcohol. These supplements can have substantial effects on other things within the body like the brain‚ liver‚ and especially the heart. For example‚ many chemicals like caffeine‚ nicotine‚ aspirin‚ and sleep aid all have effects on the body which can cause your heart rate to increase

TM How Does Temperature Affect Daphnia Heart Rate? Student Study Guide DID YOU KNOW? The body temperature of the Arctic squirrel drops from 98.6°F to 26.4°F‚ which is below the freezing point of water and is the lowest known body temperature of any living mammal. DID YOU KNOW? The average body temperature of the following warmblooded animals are: Humans: 98.6°F Rabbit: 101.3°F Polar bear: 99.1°F Blue whale: 95.9°F Owl: 104.4°F Ostrich: 102.6°F BACKGROUND Every animal

Defining the problem and selecting variables In this lab‚ we will be studying the difference of heart rate between boys and girls. There are many things that can increase heart rate‚ such as exercise‚ drinking coffee‚ taking certain pills‚ drinking an energy drink‚ feeling a strong emotion‚ etc. I have chosen to use exercise as a means of increasing the heart rate of my subjects‚ more precisely‚ 20 sit-ups. There are many reasons why your heart rate increases when you exercise‚ the most important one

neurogenic hearts. The myocardial cells need neural input from the cardiac ganglion to be able to beat whereas the myogenic hearts of vertebrates will beat without neural input. The neural input sets the resting heart rate and contractile force of the neurogenic heart. The heart rate of the neurogenic and myogenic hearts is regulated by neurotransmitters. Hearts in vertebrates are excited by epinephrine and serotonin although with varied effects and inhibited by acetylcholine. Invertebrates’ heart rates

system is composed of blood vessels‚ blood‚ and the heart. This allows the system to play an important role in the moving of both nutrients and wastes in and out of the blood to maintain an overall homeostasis within the body. The previously completed experiments each had the objective of understanding how various factors may have an influence on blood flow rate. These factors include the effect of blood vessel radius‚ the effect of blood viscosity‚ as well as the effect of blood vessel length‚ and

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

24-Hour Blood Pressure Monitoring In some patients‚ an elevated blood pressure reading taken during an office visit may not truly indicate hypertension—it could just be an occasional occurrence. These individuals are given a portable device to record their blood pressure over a 24-hour period. This helps us more accurately determine whether or not a patient usually has high blood pressure and requires treatment.

Pulse and Blood Pressure Lab (after lesson) Objectives: 1. To allow students to formulate and test hypotheses. 2. To allow students to practice taking pulse and blood pressure. Teacher notes: 1. Briefly review of how to take a pulse and a blood pressure (if necessary) 2. Instruct students to pair off 3. Students will fill out the lab worksheet which will help guide them in the lab. Answers to the questions: Using what you know about pulse and blood pressure‚ form a hypothesis about what

Based on our limited and unreliable data there is no significant increase in the heart rate or blood pressure of male adolescents when placed
