How Your Eyes And Brain Can Play Tricks On You

When we look at something, we believe what we are seeing. Nevertheless, eyes can play tricks on us. The reason why one perceives an object in a certain perspective is optic illusions. Optic illusions is a phenomenon that changes how one sees an object. This phenomenon happens because of how the human eye interprets shape, size, lines, and etc. Our brain plays tricks on us by perceiving something in a way that is not real. For example, we humans have this misconception that less hardships will lead to a happier life. Nevertheless, it actually leads to a life of boredom and sadness. As I have said, sometimes what our brain tells us is not always what the situation may be in reality.

Bow How The Sense Of Taste Works

As we all know, taste is one of the five senses that we humans have. The eyes, nose, tongue, nose, and brain play a part in taste and they make sure that we consume healthy substances instead of rotten foods. The thing that allows us to taste food are called taste cells. There are five types of tastes: sweet, sour, bitter, salty, and umani. Besides taste cells, olfactory  cells play an essential part in the sensation of taste. Olfactory cells, which are located in our nose, picks up smells. Taste is a combination of smelling food and tasting it with our mouth.

Why is it important that the body have two control systems rather than one?

It is important because that way our body can function better than if we only had one control system. Our body has two control systems: the nervous system and our endocrine system. With both of these, it is easier to respond to our surroundings and comprehend things better. The nervous system is important because it transfers messages from the brain to the body. It is the system that allows us to quickly react to what happens. An example would be the widening of your eyes when something frightens you. Our nervous system has two parts: the Parasympathetic System and the Sympathetic Nervous System. The Sympathetic system helps us decide whether one should prepare our body for fight or flight, which is known as the flight-or-flight response. As for the Parasympathetic System, it assists in calming down or body. Some signs of this system at work would be the decrease of heart beat and heart rate.

The Endocrine System is also a very important part of communication because it secretes hormones that helps our body survive the conflicts that we may face. Some hormones would include endorphins, adrenaline, and growth hormone.

In all, it is better to have two control functions such as the Endocrine System and the Nervous System because when there is two and not one control system, the communication we receive is of better quality.

What topics really confused you?
- A topic that confused me was the topics about all the bones because there were so much new words that I had to remember and memorize.

What topics do you feel very clear on?
- I felt pretty clear about the topics concerning stuff about the human body system and the cardiovascular system because I've already learned about in Biology Class.


What lab/ activity was your favorite? Why?

- My favorite lab was the the lab "Muscle Affecting The Pulse Lab". I thought the lab was pretty fun and I liked how we saw how different things such as music and exercising affected our heart rate. It was a fun experiment which filled like PE time.

What lab/activity was your least favorite? Why?
- My least favorite lab was the lab about the mink Lab. The mink smelled revolting and since I always have an urge to throw up when I smell something too strong, I did not like the time we had to spend dissecting the mink.

If you could change something about the class to make it better, for instance the type of homework (not the amount) what would it be and why?
-I guess there would be more group discussions. I find that group discussions are a good way to learn more things.

"Did you follow your diet plan for all four weeks? Why or why not? Predict your nutritional state in terms of nutrients"


During the four weeks I did follow my diet. To tell the truth I don't think I would have been able to have done  this without the help of my family and my friends. I told them about my diet project and they made sure I did not break my diet by eating any unhealthy foods such as french fries or sweets. For four weeks, I consumed lemon juice, meat products, certain fruits, and also vegetables. After having eaten like this is four weeks, I have felt that I got healthier.  Usually I don't partake in much fruits and veggies unless my parents force me to.  In order words, I'm usually a pretty picky eater. Nevertheless, during this diet I have been doing nothing but eat fruit and veggies. I think now, my nutritional state is one filled with an abundance  of proteins and Vitamin C.
