This lab experiment investigates the effect of listening to different types of music on one’s pulse. The experiment relates the circulatory system to the pulse as it measures how quickly the heart contracts and releases blood. Pulse is measured in beats per minute (bpm). One’s pulse is loudest near the heart‚ because there is more pressure closer to the heart. In contrast‚ one’s pulse is quieter the further away it is measured from the heart‚ because there is less pressure the further the distance

I practice how to assess a radial and brachial pulse. E- Initially‚ Hope explained where the radial and brachial pulse would be found and the proper position of the patient to accurately assess the pulse at both sites. Additionally‚ Jackie instructed us to use outside sources to draw where the brachial‚ radial and ulnar arteries run. To practice taking pulses‚ we worked with partners with as many classmates as possible to assess a variety of pulses and better understand possible differences amongst

How to Take a Pulse The pulse refers to the pressure of the blood pushing against the wall of an artery‚ (a blood vessel that carries blood away from the heart)‚ as the heart beats and rest. When taking a pulse you are counting beats per minute‚ (the rate) and recording three different facts about the pulse the rate‚ the rhythm‚ and volume of pulse. These facts are very important to complete information and help in assessing your patient. Also‚ when taking a pulse find arteries that lay close

Cardio Pulmonary Practical The main aim of the practical was to assess‚ what affects did light exercise have on the systolic and diastolic blood pressure‚ heart and respiration rate‚ tidal volume‚ minute volume and percentage of gas. The readings were taken before exercise‚ during exercise and after exercise. Blood pressure is defined as the amount of pressure exerted on the vessels walls‚ during blood flow. Blood pressure can be measured using a sphygmomanometer. The upper value indicates the

The goal of this project is to test whether alcohol and caffeine has an effect on heart rate‚ using the freshwater crustacean‚ Daphnia magna‚ as the experimental subject. For humans‚ alcohol works as a depressant‚ slowing down the heart rate of the consumer; caffeine works as a stimulant‚ increasing the heart rate of the consumer. The heart depends on an internal pacemaker system to keep it pumping consistently and at the right speed. Alcohol disturbs this pacemaker system and causes the heart

of alertness (a CNS effect) but also a higher heart rate‚ blood pressure and respiratory rate. Caffeine also acts as a stimulant drug‚ causing increased amounts of stimulatory neurotransmitters to be released. At high levels of consumption caffeine has been linked to restlessness‚ insomnia and anxiety‚ causing raised stress and blood pressure. This can lead to heart and circulation problems. Hypothesis: Daphnia subjected to a caffeine solution will show a rise in heart rate as caffeine is a stimulant

Caffeine effect on Daphnia’s heart rate Prepared for: Androniki Kloni By: Maria Mitsi October 6‚ 2013 Abstract Caffeine is a bitter‚ white crystalline xanthine alkaloid and a stimulant drug. Caffeine is found in varying quantities in the seeds‚ leaves‚ and fruit of some plants‚ where it acts as a natural pesticide that paralyzes and kills certain insects feeding on the plants‚ as well as enhancing the reward memory of pollinators. An experiment was held‚ on an aquatic

Effects Of Exercise in Differents Body Systems Cardiorespiratory System - The vital capacity of the lungs can be increased though regular aerobic exercise. This makes the oxygen exchange system more efficient (Pangrazi‚ et al. 1997. p.322). Circulatory System - Heart rate‚ stroke volume‚ cardiac output‚ and blood pressure increase significantly during resistance exercise. The blood pressure response increases nonlinearly with the magnitude of active muscle mass and is higher during the eccentric

Customize exercises will help to strengthen weak muscles and watch for muscle substitution. For example‚ a patient may show hip hiking and a circumduction gait pattern as a result of substitution hip flexors .Some exercises are helping to improve balance and mobility through valuation of different mobility aids‚ Addition to that postural
