Explain the “lub-dub” sounds of the heartbeat.

 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:

  • Complete the blood pressure and pulse reading table.
  • Answers questions one through six
  • Your assignment must be formatted according to APA      guidelines as outlined in the Ashford Writing Center.

Carefully review the Grading Rubric for the criteria that will be used to evaluate your assignment.

Post-Lab Questions:

1. What is systolic pressure? What is diastolic pressure?

2. Why is blood pressure a sensible reading to measure circulatory health?

3. Explain the “lub-dub” sounds of the heartbeat.

4. Why do blood pressure and heart rate change after exercise?

5. How might the results in Table 2 change if someone else preformed the activities? Why?

6. Why is it important for blood to flow in only one direction?
