In lecture class we discussed the HEART! The heart is quiet amazing. It pumps blood all through our entire body and keeps us alive. There are many parts to the heart. It is made up of muscles, veins and artery's.
Coronary Circulatory Pathways. These artery's wrap themselves around the entire heart. The first two branches are the left and right coronary artery's.
An interesting fact is that the top of the heart is the base. Usually when things are referred to as the base it means this bottom. But the base of the heart is actually the top. Kinda cool!
The artery's also have valves. Valves are flaps of fibrous connective tissue. when the weight/volume of the blood becomes great it pushes the valves open and blood is pumped through our body.
There are also tiny white chords in our heart. The chords tighten to help the valves close. We just did the heart dissection in lab and saw these chords. It is pretty cool to think that those are actually in our heart. Also 10% of people have a Mitral Valve Disorder.
I always wanted to know what a bi-pass
surgery was. And in lecture I finally found out what it was! It is when a vein from the leg is taken and placed in the heart. It is placed as a bridge over part of the that is blocked. This can be single, double or a triple if needed.
The heart also has an electrical conduction.
The Electrocardium is simple squamous cells.
The Myocardium is cardiac muscle cells.
The Epicardium is also known as the "Peri-Cardium"
