Chapter 27, Problem 1.1BGL

(a)

Summary Introduction

To label: The heart structures in Figure 27.2(a)

Introduction: The heart is the muscular organ that weighs about the size of the fist. The main function of the heart is to transport the oxygenated blood to all parts of the body. It consists of four chambers namely right atrium, left atrium, right ventricle, and left ventricle. The blood vessels called arteries and veins are involved in the transport of blood to the tissues and from tissues to the heart.

Fig 1: The anterior view of the heart.

Explanation of Solution

The structures of the anterior view of the heart is reviewed as follows:

Right auricle: It is the muscular cone shaped pouch that is attached to the right atrium of the heart. It is also called as right atrial appendage.

Cononary sulcus: It is the structure that separates the atrium of the heart from the ventricles. There are two coronary sulcus present in the heart namely right coronary sulcus and left coronary sulcus.

Right ventricle: It is one of the four heart chambers. It plays an important role in carrying the deoxygenated blood from the heart to the lungs.

Left auricle: It is the muscular cone shaped pouch that is attached to the anterior surface of the left atrium of the heart. It functions in increasing the pumping capacity of the left atrium.

Anterior interventricular sulcus: The heart consists of two interventricular sulcus namely anterior interventricular sulcus and posterior interventricular sulcus. It plays an important role in separating the ventricles of the heart.

Left ventricle: It is one of the four heart chambers. It plays an important role in carrying the oxygenated blood to all parts of the body.

Apex of heart:   It is present in the left side of the heart between the fourth and fifth ribs. It consists of the left ventricle. It plays an important role in regulating the contraction of the ventricles.

Fig 2: The posterior view of the heart.

Explanation of Solution

The structures of the posterior view of the heart is reviewed as follows:

Left atrium: It is one of the four heart chambers. The oxygenated blood from the lungs enters into the left atrium.

Coronary sulcus: It is the structure that separates the atrium of the heart from the ventricles. There are two coronary sulcus present in the heart namely right coronary sulcus and left coronary sulcus.

Left ventricle: It is one of the four heart chambers. It plays an important role in carrying the oxygenated blood to all parts of the body.

Adipose tissue: The adipose tissue that surrounds the heart plays an important role by acting as cushion and insulates the heart.

Posterior interventricular sulcus: The heart consists of two interventricular sulcus namely anterior interventricular sulcus and posterior interventricular sulcus. It plays an important role in separating the ventricles of the heart.

Right atrium: It is one of the four chambers of the heart that receives the deoxygenated blood from the vena cava and pumps to the right ventricle.

Right ventricle: It is one of the four chambers of the heart that sends blood to the lungs to get oxygenated through the pulmonary arteries.

The diagram below illustrates a quorum sensing pathway from Staphylococcus aureus. Please answer the following questions. 1. Autoinduction is part of the quorum sensing system. Which promoter (P2 or P3) is critical for autoinduction? 2)This staphylococcus aureus grows on human wounds, causing severe infections. You would like to start a clinical trial to treat these wound infections. Please describe: a) What molecule do you recommend for the trial. Why? b) Your trial requires that Staphylococcus aureus be isolated from the wound and submitted to genome sequencing before admittance. Why? What are you testing for?  3) If a mutation arises where the Promoter P3 is constitutively active, how would that influence sensitivity to AIP? Please explain your rationale. 4) This pathway is sensitive to bacterial cell density. Describe two separate mutation that would render the pathway active independent of cell density. Briefly explain your rationale. Mutation 1 Mutation 2
