The Brain and the spinal cord is the part of Central Nervous System. It's the collection point of nerve signals. It interprets the stimuli. All the other nerves that isn't in the brain nor the spinal cord connects the limbs and the organs with the central nervous system. It receives and carries the signals throughout the body making the limbs and organs to act.

The fact that an organ in our body actually balanced the blood was an interesting fact. Also it was very interesting to see Urea, Water, Glucose, Protein and Sodium carried to the blood through a visual representation.

Everything Correct

Observations during a lab can be be recorded down as picture, graphs, tables and videos. Like what Julia and Bohoon had said earlier. But it can also be recorded down as descriptions of the changes or the reactions of the dependent variable. It can be a little hard trying to describe everything that is happening during the experiment but it is the most basic way of recording observations.

It is important to be careful when we record our observations because wrong recordings can mislead the whole experiment. Also, when the change or the reaction of the experiment hasn't be recorded well, the result can be interpreted in different ways, absolutely changing the result of the experiment. To come up with the most accurate and reliable result of the experiment, it is very important to be careful when recording the observations

Hypothesis is a specific educated statement of prediction about the result of the experiment.
A scientific hypothesis should be able to be tested. A hypothesis is about the consequence or the result of an independent variable affecting the dependent variable.

Coughs, Breath deeper and more frequent
Organs and tissues in the body don't have enough air supply and begin to disfunction.

-Heart rate increases
-Breathing rate increases
-Produces Lactic Acid
-Shortage of Breath

Breathing is the constant process where we take in oxygen, and expelling carbon dioxide
Respiration is the metabolic process of breaking down the oxygen, so that the cells can use it
