Bio Lab: The Effect of Exercise on The Respiratory and Circulatory Systems Ellie Cookson Communication: 2. As the graphs show‚ both breathing rates and pulse rates spike significantly between the resting rates and immediately after exercise. Average breathing rates went from 26.7 breaths/min at sitting rate to 46.4 breaths/min during or immediately after exercise. Pulse rates also increased quite dramatically‚ going from an average of 65 beats/min at rest rate to an average of 100.3 beats/min

Caffeine’s Effect on Blood Pressure in Teens Research Questions How does the caffeine in coffee affect the blood pressure in teens within an hour? Purpose The purpose of the lab is to see the different effects of coffee in teenagers who have a different lifestyle. Also‚ my purpose is to be informed as well considering I’m a 17-year-old teen that drinks coffee on a regular base. I would like to know how all the coffee I have ever drunk‚ has had an effect in my body that I’m not aware of. Hypothesis

The systems of the body. Systems are the most complex of the component units of the human body. A system is an organization of varying numbers and kinds of organs arranged so that together they can perform complex functions for the body. There are 10 systems in the body‚ but the 3 main are: • The nervous system • The respiratory system • The circulatory system The nervous system. The nervous system has two main parts: • The central nervous system – CNS; This is composed of the brain and the spinal

to measure arterial blood pressure. Questions: 1. My blood pressure for this lab was 123/78. These numbers are normal‚ compared to the normal rating of 120/80. My pulse pressure was 45 (SP – DP). My mean arterial pressure was 93 (DP + 1/3 (SP – DP). 2. Mean arterial blood pressure is determined by cardiac output and total vascular resistance. The mathematical equation for mean arterial blood pressure is equal to cardiac output x total vascular resistance. The amount of blood pumped out of the heart

2 September 2014 Chapter 1 Review 1. Describe the characteristics of science. A. The characteristics of science are observations‚ search for regularities‚ process the information‚ and self-corrections. Science is based upon observations that incorporate our senses‚ or instruments that extend our senses‚ to interpret natural experiences. Science is a searh for regularities. These regularities may include observed phenomena or patterns in nature. After observations have been recorded about regularities

Introduction: This investigation used spectroscopy to evaluate light absorption in different solutions. A spectrophotometer was used in the lab to determine these values. A spectrophotometer is an apparatus used to “measure the absorption of radiation in the visible and UV regions of the spectrum and allows precise at a particular wave length” (Jones et al.‚ 2007). The amount of light absorbed by a substance is directly in relation to the concentration of the solute and also the wavelength moving
