ARTEFACT: COW'S HEART DISSECTION:
The photograph shown below is the heart of a cow. As a class, we got to explore and physically touch the parts of the heart such as ventricles, atria and also the aorta. We also examined the muscle of the heart, its texture and structure. We cut the cow's heart into half so that we could see the different arteries and veins in the heart. I found the similarities between a cow`s heart and a humans heart very surprising. The reason for this is because a cow appears to be very different from a human, however from the inside, the structure is similar to that of the human heart. Also we both have the same vital organs needed to survive. However, the heart dissection is probably one of the most difficult dissections we did. Part of the reason it was so difficult to learn was that the heart wasn't perfectly symmetrical, but it yet so close that it becomes difficult to discern which side you are looking at (dorsel, ventral, left or right). Finding the vessels is directly related to being able to orient the heart correctly and figuring out which side you are looking at. It is also difficult because the fatty tissue that surrounds the heart can obscure the openings to the vessels. This means that you really must experience the heart with your hands and feel your way to find the openings. And because the heart is slippery, it is easy to drop.

ARTICLE:
Blood pressure is related to age, study made by students of Madras Medical College, Chennai, India.
Summary:
The importance of monitoring blood pressure is vital to the well-being of millions. This is because radical blood pressures can result in a heart attack or stroke, which affects about 1/3 of the population in the United States and United Kingdom. A group of researchers at the University College London, apart of the Medical Research Council Unit for Lifelong Health and Ageing, discovered a substantial change in blood pressure at four different stages in life: adolescence, early adulthood, mid-adulthood, and late adulthood. Youths would have the fastest spike in blood pressure, while late adults would face a slight increase and then decrease. These results came from a study conducted by the team, involving 30,372 individuals (aged 7-80). In addition to the stages of blood pressure acceleration, it was discovered that working individuals had lower blood pressures then the general group, which means lifestyle would also play a major role in blood pressure spiking.
Reflection:
This article is not extremely descriptive and explanatory, but does introduce some important knowledge on blood pressure. This is important to the me as a student and citizen because me, family, friends, and the community could one day suffer from blood pressure related problems so this knowledge could be an aid in taking preventative measures to stop the likes of heart attacks, strokes, or any other type of cardiovascular problem. This is because we'll be able to monitor and further maintain safe blood pressure rates at certain stages of life. The next step would be building the knowledge and then apply it to real life, through awareness.
