Past Main Lessons
Our main goal in an equation with an unknown variable is to do this.
What is to isolate the variable on one side of the equation. (Get the "x" alone -- or what ever letter represents the unknown number.)
Located behind the lens and in front of the retina. This gel-like fluid helps maintain the shape of the eye.
What is the vitreous humor.
This fundamental gas plays a small part in breathing. We actually only use about 5% of this, and the rest is exhaled as mostly carbon dioxide.
What is oxygen.
This sends blood throughout our bodies, carrying oxygen to every cell, and sends blood to the lungs to receive oxygen.
What is the heart.
This is the 'food tube.'
What is the esophagus.
This is the formula for the mechanical advantage of a lever (MA).
What is MA = Li/Lo. (length of the input arm divided by the length of the output arm of the lever.)
The smallest bones in our body are located here. (be specific)
What is the middle ear.
Our respiratory system starts here.
What is the nose or the mouth.
The systemic circulation carries blood from the heart to all the other parts of the body and back again. This system is a short loop from the heart to the lungs and back again.
What is the pulmonary system.
The Olfactory bulb (gustatory cortex) recognizes what from our taste buds?
Whether a food (tasting) is salty, sweet, bitter sour savory, etc.
This was discovered in AD 850, brought to Europe during the 1200's, and altered the way that human beings wage war, brought an end to the Medieval Ages in Europe and made the Age of Exploration possible.
What is gunpowder.
This is the most common protein found in our integumentary system.
What is keratin.
This is the windpipe.
What is the trachea.
These type of blood vessels have very thin walls, and through them, nutrients and oxygen are delivered to the cells. Waste products are also brought into these blood vessels.
What are capillaries.
This is what we call waves of muscle contractions that force food down through the esophagus to the stomach.
What is peristalsis.
The relationship between two angles that, together, are 180 degrees is called what?
What is supplementary. (or a straight line)
This is the hardest part of our body.
What is enamel.
This is the dome-shaped muscle at the bottom of the lungs which controls breathing and separates the chest cavity from the abdominal cavity.
What is the diaphragm.
William Harvey, an English doctor, proved that blood circulated through the body in one continuous direction toward the heart, and was 'pushed' (controlled) by the heart, by doing what?
What is tying a cloth band (tourniquet) around the upper arm, and observing the blood flow of the veins appearing to pop out of the arm.
This is the digestive enzyme in saliva.
What is amylase.
Water can be a drink, an ionizer, reduction agent, a solvent and what -- according to the great M&M experiment we performed in class?
What is a catalyst.
Without this, we wouldn't be able to taste anything.
What is saliva. (Remember where the taste buds actually are located, and remember how 'tastants' enter our taste buds.)
The bronchial tubes are lined with these tiny hairs that move back and forth, carrying mucus up and out.
What is cilia.
This is caused by blood stopping and starting as it rushes through your arteries.
.
What is a pulse.
These are the bean shaped organs whose main function is to filter out water-soluble waste products from the blood.
What are the kidneys.
