Two of the latest technologies used by doctors image the heart of their patients are Magnetic Resonance Imaging and the 64-Slice Computed Tomography.
Magnetic Resonance Imaging is a system that allows the cardiologist to see how the heart beats and functions through the detailed video generated using the process. MRI uses magnetic waves and radio waves to create the images.
It is then passed on to a computer for viewing. MRI is noninvasive method, which is an advantage because no needles or tubes are subjected to the patient just to conduct the procedure. But since it uses radio waves, patients with pacemakers cannot use it. The entire process also takes too long to complete, when compared to other cardio-imaging methods.
The 64-Slice Computed Tomography, on the other hand, follows the same technology as the traditional CT scan. Only for this one, the detectors are reinforced for optimum heart imaging. The body is placed under multiple X-ray beams and the machine’s 64 detectors will then start producing a three dimensional rendition of the patient’s heart.
One of the advantages of the 64-Slice CT scan is that doctors will have the ability to discriminate the distance between two objects. This allows them to make a more accurate diagnosis of the heart problem. But because CT scan uses x-ray beams, subjecting the body too much to radiation could be dangerous, especially to the fetus of a pregnant mother (Fuster, et al 2004).
The sticky, dried mucus we find inside our noses is called snots and boogers. Snots are the sticky type and the dried ones are called boogers. They have only one function – and that is to trap the dirt, germs, smoke, sand, pollen, fungi, and all other small particles from entering through our noses.
Our nose is the primary pathway to our lungs. The presence of these two inside our noses prevents all the small elements from invading our body, which could eventually cause sickness and diseases. The mucus, along with the hairs inside the nose, filters the air we breathe. When we inhale, the dirt is trapped in. As we exhale, the dirt is being pushed out (Avila 1995).
The funny sounds we hear from our stomachs when we are hungry come from the small intestines. The muscles inside our intestines tend to contract to push the food, as well as the intestinal juices, down the abdominal tract.
The process of pushing the food is done on a regular basis, even if there is no food present in the stomach. And that is the reason why the grumbling sound is relatively louder when you are hungry. There is no food to be pushed down at all. When that happens, acids are produced instead. And so the body reacts accordingly to achieve homeostasis. Homeostasis is the process of maintaining a stable internal body organs and overall well-being. In response to this state, the body has to drive the acids outside of it. And so we hear those growling sounds (Fracchia 1994).
Infant Respiratory Distress Syndrome is a case wherein infants have problems with breathing right after the moment they were born. This condition is very common in premature babies. Babies born with less than nine months inside their mother’s womb have high risks of obtaining lungs that are not yet fully developed.
Premature babies have lungs that contain underdeveloped surfactants. That being the case, the alveoli in the lungs do not have the ability inflate just yet. There are some premature babies who cannot even breathe on their own, mainly because their lungs are very stiff. Babies under this state are subjected to an oxygen hood or a ventilator, depending upon the severity of their case, for treatment.
They are also given drugs that act similarly to the surfactant found in the lungs. Those drugs can facilitate the lung’s growth. Several other medical procedures can be undertaken, such as placing a tube on the baby’s chest. Doing so, will prevent the accumulation of air in the lungs, causing it to collapse and produce more damage (Avila 1995).
A lower pH is not seen on the venous side of the circulatory system because our bodies tend to offset the whole situation. When the carbon dioxide content in the body, more particularly in the venous side of the heart reacts with water, several H+ ions are produced. The number of H+ ions produced is proportional to the number of carbon dioxide molecules that reacted with water.
As the concentration of the H+ ions increases, the pH level becomes lower. But during this point, a message is transmitted to the brain, telling it of the current condition the body is in, which is, in this case, is its low pH level. The brain then instructs the body to breathe faster and deeper to counteract the scenario.
The body can do some other preventive measures, but this is the main reason why we do not see a lower pH on the venous side of the circulatory system. Our whole system, including the brain, is responsible to bring the condition back to its normal and neutral pH levels (Fuster, et al 2005).
