Summary Introduction

To determine: The differences between the flows of fluid in closed circulatory system from the movement of molecules between cells and their environment with regard to distance traveled, direction traveled, and driving force.

Introduction: A circulatory system has three basic components including a circulatory fluid, a set of interconnecting vessels, and a muscular pumping system called as the heart. By transporting circulatory fluid (usually blood) throughout the body, the circulatory system links the aqueous environment of the body cells to the organs involved in gaseous exchange, nutrient absorption, and disposal of wastes.

Explanation of Solution

The differences between the flows of fluid in closed circulatory system from the movement of molecules between cells and their environment with regard to distance traveled, direction traveled, and driving force are given as follows:

CharacteristicsFlow of fluid in closed circulatory systemThe movement of molecules between cells and their environment
Distance traveledMillimeters to metersLess or equal to 1 millimeter
Direction traveledSingle directionRandom direction
Driving forceATP-driven muscular pumpDiffusion

Awnser these Discussion Questions Answer these discussion questions and submit them as part of your lab report. Part A: The Effect of Temperature on Enzyme Activity Graph the volume of oxygen produced against the temperature of the solution. How is the oxygen production in 30 seconds related to the rate of the reaction? At what temperature is the rate of reaction the highest? Lowest? Explain. Why might the enzyme activity decrease at very high temperatures? Why might a high fever be dangerous to humans? What is the optimal temperature for enzymes in the human body? Part B: The Effect of pH on Enzyme Activity Graph the volume of oxygen produced against the pH of the solution. At what pH is the rate of reaction the highest? Lowest? Explain. Why does changing the pH affect the enzyme activity? Research the enzyme catalase. What is its function in the human body? What is the optimal pH for the following enzymes found in the human body? Explain. (catalase, lipase (in your stomach),…
