Blog 20 Male and Female Dissection


Quite fascinating. I was glued to the screen as the scientist removed the parts of the human body. The feat of having plasticized the body was great enough, but able to bring out bodily organs like that... was just amazing. I learned more about the form of the organs and how they all fit into the body's frame. I was amazed at how much tubing each gender has in their body, and how it all works in sync every day, every second of the day. And when procreation is the goal, I was shocked that so many parts of the body had to work together just to move the sperm along. The processes were immense and complicated in some parts, but it was to execute a mainly simple thing, which was ejaculation. Our bodies are so fascinating because they are formed to fit and complement each other. Amazing.

Blog 19 Urine... As a Diagnostic Tool


Urine is a powerful indicator of the status and well-being of the body. Urine is the vehicle on which most of our toxins and other wastes are removed from the inside of our body. In many cases, urine will point out the blood sugar levels in the person, indicative of diabetes or not. Toxins that can end up in urine can point out too much (usually), or too little (less usual) of a certain substance in the body. The color, smell, and amount of urine all point to whether or not the person is healthy.

Blog 18 Fetal Pig Dissection


I personally don't like dissections. I hope I don't freak out when I'm a dentist. Hopefully I will gain a better stomach for such things.

I thought the pig dissection was really nice and fundamentally educational. I just didnt like the smell that much. The step by step instructions and the way the body of the pig just falls out piece by piece is very... awe-inspiring. I liked how we could get all of the insides out in the end, and have measurements of all the parts too. It was... bio heaven. The digestive tract was the most impressive part, because we had to be delicate and careful when removing it and when we were measuring it.

Sadly, there is no protection against the smell of decaying bodies of little pigs...

Blog 17 What We Learned about the D.S. from the Video


The digestive system is quite simple and straightforward, but its many components and parts add to its profound complexity. The whole system is a bodily miracle/feat that allows the body to survive through many facets of its design and function.

Starting from our oral cavity, food is taken in and already begins to be broken down by the saliva and other peptides. Down the pharynx the bolus travels by peristalsis. In the stomach, bile and other enzymes that are released primarily from the pancreas help break down the various kinds of foods being digested.

Into the small intestine via the pylorus sphincter the chyme travels. The peptides and other enzymes that break down the carbs and fats will allow the microvilli along the walls of the small intestine to carry nutrients away from the tract. The whole tract, including the small, and large intestines, with the stomach, and the throat, all amounts to about 3 table lengths, even longer when completely unraveled and stretched out.

After the small intestine, the remaining by products are moved into the large intestine, where water reabsorption is largely conducted, and then finally excreted from the body.

Blog 16 How to Protect Your Digestion


Your digestive organs are key to maintaining a functioning body. If the digestive organs are impaired in any way, there are consequences that can ultimately lead to death, if not severe pains. Eating foods that are of a variety in the pH scale will balance out the bile needed and therefore have less acidity inside the stomach. Too much acidity commonly leads to ulcers and heart burn. Chewing your food completely will allow better digestion, so the food does not need more acids to break down. 

Aside from eating, cooking the food is a big must. Bacteria inside uncooked foods can infect and damage the organs, sometimes to the point of no return. It is best to make sure the food is cooked properly so that food poisoning does not occur. Better yet, buy organic and foods that are fresh, to lower the chances of catching something nasty.


Blog 15 Protection Against Infectious Diseases


We are all prone to infectious diseases. But by maintaining good hygiene and boosting the immune system we can hold off feeling the full effects of being infected/sick. Bacterial diseases travel by contact and are airborne. By washing your hands after touching something you believe could be a carrier for the bacteria will dramatically lower the risk of catching the disease. Stay away from others who are sick (quarantine), and that can lower the chances of getting sick too. Eating healthy foods that boost the immune system will improve your health and lower the chances of catching the disease.

Viruses are harder to protect against. Like bacterial infections, it is best to reduce contact with those who have it. Keeping good hygiene and eating foods that boost the immune system are key to good health and staying that way. Staying away from strenuous activities or situations will also allow the body to recuperate and heal. Sleeping will let the body rest and continue the fight against the disease.

Blog 14: Allergies

Perhaps it's because I have it too, which explains why I dislike talking about allergies. My eyes water, even when I'm not sad, which makes me sad. My nose itches a whole bunch, and I start dripping mucus out of them like I was melting on the inside. Plus, the sneezing makes others think I'm sick, when in reality I'm not.
Allergies are an over exaggerated response to substances that would not have caused such responses in people with normal circumstances. It is an immediate response and often referred to as hypersensitivity. When the allergens enter the system, huge amounts of white blood cells called masts cells are formed on site, resulting in an extreme inflammatory response. Symptoms range from, but are not limited to: allergic conjunctivitis, itchiness and runny nose.
Allergens that are airborne cause the symptoms when they reach the eyes, nose, and lungs. Breathing in allergens can also lead to asthmatic symptoms, due to constricting airways and overproduction of mucus. Aside from airborne allergens, those from food or insects can cause symptoms like nausea, diarrhea, and vomiting.
