Week 4 – Laboratory 1
Blood Pressure
This week, you will log in to eScienceLabs to complete the two lab exercise assignments. These labs cover the cCirculatory and rReproductive sSystems. You will learn about these systems via animations and pre-lab readings for the exercises. The animations will address the anatomy and physiology of blood and the heart, the circulatory system, blood pressure, and the reproductive system.
The pre-lab readings will reinforce the elements of the circulatory system, including the role the respiratory system plays, the branches of the circulatory system, blood pressure, and cardiac output. You will viewView the Blood Pressure Virtual Lab animation before completing the Lab Report data and questions; data from the animation will be used in the Lab Report. Throughout the Blood Pressure lab, you will learn the basics on how to take a blood pressure reading, how blood pressure shows circulatory health, and what the normal sounds of blood pressure indicate, and how exercise impacts blood pressure.
For this assignment you must:
Carefully review the Grading Rubric for the criteria that will be used to evaluate your assignment.
