Introduction
The dissection was conducted to be able to identify the respiratory tract such as the trachea, bronchus and more. Locate the various chambers of the heart and other major structures.
Method
First the lungs and heart were set out so the tubes that are entering the lungs are at the top and the heart was underneath the lungs. Start to examine the trachea and examine the longitudinal structure of the trachea. Cut a section of the trachea to be able to examine the internal structures, and then cut down to where the tracheal bifurcation is. The next step was to examine the lungs and the division of the lungs into the lobes. From cutting the trachea, next you would cut open bronchi and follow it down. Identify the pericardium and …show more content…
The left lung has 3 lobes and the right lung has 4 lobes. ANATOMY BOOK
The heart
The heart is a muscular organ that pumps blood through the blood vessels and round the body. The heart is enclosed by the pericardium. The pericardium is a double layered serous sac. The heart is located between the two lungs in the middle of the chest; it will be behind and slightly to the left of the sternum. ANATOMY BOOK
The heart consists of various tissue types (Revision World, 2015). The most important muscle the heart has in it is called the cardiac muscle (Revision World, 2015). Each cell that contributes to the heart is called myogenic; this means that it has its own inherent rhythm (Revision World, 2015).
The heart consists of four different chambers.
1. Right atrium
2. Left atrium
3. Right ventricle
4. Left ventricle
The atria are a lot smaller than the ventricles. The walls of the atria are a lot thinner and a lot less muscular than the ventricles. The atria are there to act as receiving chambers for blood. They are connected to the veins which takes the blood to the heart.
The ventricles are much larger they are also much stronger to be able to pump blood out of the heart. The ventricles are connected to the arteries that take the blood out of the heart
