Cardiovascular System Lab – Week Six
Introduction
The cardiovascular system consists of blood, blood vessels, and the heart. As you learn about the various diseases that affect the cardiovascular system, it is important for you to understand the structures that can be affected by disease. Complete this lab to become familiar with a healthy system and to identify diseases related to this system.
PART ONE: basic functions
Provide brief answers to the following questions to help you get acquainted with the basic functions of a healthy cardiovascular system. Refer to Ch. 23 in Microbiology: Principles and Explorations.
- What are the main functions of the cardiovascular system?
- Which types of bacteria are considered normal cardiovascular system microflora?
- Which structure of the cardiovascular system is particularly susceptible to bacterial infection?
PART two: basic structures
Refer to Ch. 23 in Microbiology: Principles and Explorations to help you identify the selected cardiovascular system structures in the following diagram.
Visit Chapter 23 of Microbiology: Principles and Explorations in WileyPlus to view an in-depth presentation of a healthy cardiovascular system by completing the following steps:
- Select the Chapter 23 WileyPlus reading link located on your student Web page.
- Locate the heading Chapter Review.
- Select the Anatomy Overview: The Cardiovascular System
- Complete this lab as you explore the Cardiovascular System multimedia piece.
Cardiovascular System: The Heart
Roll over each component of the Cardiovascular System multimedia piece. Roll over and click the heart. Refer to the Heart component of the multimedia piece and Ch. 23 in Microbiology: Principles and Explorations to label the structures in the following diagrams of a healthy cardiovascular system.
PART three: investigate and apply
Select one of the following diseases related to the cardiovascular system, discussed in Ch. 23 of Microbiology: Principles and Explorations:
- Rheumatic fever
- Bacterial endocarditis
Describe the causal agent of the selected disease, mode of transmission, disease characteristics, and the component(s) of the cardiovascular system that are damaged by the disease.
