The subphylum Vertebrata includes all the familiar animals we tend to see everyday, and some rare and unusual ones (O’Neil, 2012). Scientists classify the seven different Vertebrates based on their skeletal system, general environmental adaptation, and reproductive systems. These seven Vertebrates include, Agnatha, Chondrichthyes, Osteichthyes, Amphibia, Reptilia, Aves, and Mammalia. During the lab dissection, the class dissected organism from only four of these classes. First, we dissected the…

Interventional cardiology is a relatively new field in medicine. The doctors within this field treat heart diseases through minimally invasive procedures through the use of catheters, stents, and balloons. Catheter are thin tube made up of several types of material depending on how it will be used. A stent on the other hand is a tube composed of metal that can remain within the body to keep a blood vessel open. Interventional cardiology is said to be first discovered by Andreas Gruentzig in…

increase in pulmonary blood flow. VSD is a hole in the wall separating the two lower chambers of the heart (AHA, 2016). The blood is shunted from the left ventricle artery, across the open septum into the pulmonary artery without any impediment (Ball & Bindler, 2008). The opening may cause a higher pressure in the heart or reduced oxygen to the body (AHA, 2016). This is the most common congenital heart defect, as reported by Ball & Bindler (2008) and it is responsible for about 40% of all…

Running is a very inexpensive form of exercise. All that it takes is time and effort. A person can run almost anywhere, a park, a trail, a track, a neighborhood or even on a treadmill. Running is an excellent exercise for the cardiovascular and respiratory systems. It focuses on the leg muscles, toning and strengthening them. If a person is not sure how to start a running program, there are options for them. Couch to 5K is a program that gives a person a starting point and lets them build up to…

THE CAUSES OF HEART ATTACK The onset of heart attack is a result of a portion of cardiac muscle having necrosis, which is caused by an obstruction of a coronary artery through artherosclerosis, a thrombus or spasm. Heart attack often occurs when the flow of oxygen-rich blood to a section of the heart muscle becomes blocked which is mostly a result of coronary heart disease (NIH, 2012). According to National Institutes (NIH), Coronary heart disease is a condition that is as a result of a waxy…

There are several causes of high blood pressure (Hypertension) some of which we do not have any direct control over, and yet we can still modify the effects of these factors by ensuring that we pay attention to the things that we do have some control, over. I will discuss both kinds on this page so that by the end you know exactly the kind of things you can easily change to reduce the risks associated with high blood pressure, and you know the things that you cannot change so easily and yet can…

utilized to check the heart 's rhythm and electrical signals. Sensors fixed to the skin are utilized to detect the electrical signals created by the heart every time it pulsates. These signals are recorded by an ECG and are diagnosed by a cardiologist or GP to check abnormalities or presence of heart disease. The ECG is commonly used by trained technicians to analyze and screen conditions influencing the heart. It can also be used to examine side effects of a possible heart issue such as chest…

Some of the deadly consequences of malnutrition are electrolyte imbalance, muscle loss, immunity and blood flow issues, and heart problems. Once the body reaches the point of malnutrition it goes into what is known as starvation mode. When a body lacks the nutrients it needs it will take from itself. When the human body has an electrolyte imbalance caused by starvation there…

Heart Murmurs and its Effect on the Body System Unusual or abnormal sounds that are heard during a heartbeat are referred to as heart murmurs. Murmurs can range from very faint to very loud and sometimes sound like a whooshing or a swishing noise. Although heart murmurs can be present at time of birth they can also be developed later in life as well. Heart murmurs are not diseases but can indicate an underlying heart problem. Normal heart beats usually make a “lub-dub” type of sound which…

For over 55 years, humans have been flying in space. With an understanding of evolution, it has always been assumed that human bodies have adapted to the gravitational force found here on Earth. The space station and the shuttle that most NASA astronauts will stay in orbits 350 km above Earth, with a gravitational pull 90% stronger than it is on the ground (NASA Space Bones). Giancoli describes objects orbiting the Earth as feeling weightless because they are, in essence, free falling towards…
