Summary Introduction

To determine:

The comparison between the relative thickness of the walls of the heart chambers of the fetal pig.

Introduction:

The circulatory system of a pig contains a four-chambered heart that pumps blood to and from the lungs and other body parts. The blood transports back to the heart via veins and the blood is transported to the other body parts by arteries.

Explanation of Solution

There are four chambers in the heart of the fetal pig, the right ventricle, the right atrium, the left ventricle, and the left atrium. The walls of the atrium are much thin as compared to the ventricle. Moreover, the left ventricle is much thicker than the right ventricle.

Conclusion

The walls of the atrium are much thin as compared to the ventricle. Moreover, the left ventricle is much thicker than the right ventricle.

Preoperative Diagnosis: Torn medial meniscus, left knee Postoperative Diagnosis: Combination horizontal cleavage tear/flap tear, posterior horn, medial meniscus, left knee. Operation: Arthroscopic subtotal medial meniscectomy, left knee Anesthetic: General endotracheal Description of Procedure: The patient was placed on the operating table in the supine position and general endotracheal anesthesia was administered. After an adequate level of anesthesia was achieved, the patient's left lower extremity was prepped with Betadine scrubbing solution, then draped in a sterile manner. Several sites were then infiltrated with 1% Xylocaine solution with Epinephrine to help control bleeding from stab wounds to be made at these sites. These stab wounds were made anterolaterally at the level of the superior pole of the patella for insertion of an irrigation catheter into the suprapatellar pouch area, anterolaterally at the level of the joint line for insertion of the scope and anteromedially at…
