100
Where does digestion start?
In the mouth.
100
Relating to the heart
cardiac

What are the simple names for the pharynx and the larynx?
The throat and the voice box.
100
What is the excretory system?
The system that gets rid of cell wastes in the form of urine.
100
What do your ears do? (This one is VERY obvious) I couldn't think of anything for a 100 question. What is a reflex action?
THEY HEAR! DUHHH! Actions that happen automatically.
200
What does the digestive system do?
It breaks down food for your body to use.
200
A blood vessel that carries blood to the heart
Vein
200
What is the job of the respiratory system?
To get oxygen into your body and to get rid of carbon dioxide.
200
True or False? Your bladder explodes if you hold urine in for too long. What is perspiration?
FALSE! Liquid waste made of heat, water, and salt released by the skin.
200
The part of your brain that controls your balance.
What is the cerebellum?
300
Are carbohydrates, proteins, and fats digested the same way? Think of the website we explored. Explain.
They take different amounts of time to get digested, and our body absorbs different chemicals from each. Carbohydrates into sugars Proteins into amino acids Fats into fatty acids and glycerol
300
A blood vessel that carries blood away from the heart
Artery
300
What muscles helps you breathe besides your lungs? How does it do this?
The diaphragm tightens, and separates the lungs from the abdomen. It allows air to fill up the lungs.
300
Why are our kidneys important to us?
They are the main organs of the excretory system, and they help filter nitrogen wastes out of the blood. They also remove extra water and salt from the blood. These liquid wastes become urine.
300
What would happen if you somehow lost, damaged, or had your brain stem removed?
Your automatic functions such as breathing, thinking, and heartbeat stop working.
400
Describe the path that food takes through the digestive system.
You eat food and chew it in your mouth. Then it it broken down by saliva and digestive enzymes. It moves into your throat, or pharynx when you swallow, and then down the esophagus into the stomach. The digested food goes into the stomach and becomes chyme. The chyme moves into the small intestine then large intestine. Lastly, wastes are pushed out.
400
The force of blood against the walls of blood vessels
Blood Pressure
400
A tiny sac at the end of each bronchiole that holds air. (Plural is ******i.)
Alveolus
400
Explain how holding your nose would affect how you taste food. Name four kinds of messages receptor cells in the skin receive.
The food would taste different between there are only sensory receptors from the mouth going to your brain inside of both your mouth and nose. Messages about heat, cold, pressure, and pain
400
How do impulses travel between neurons?
They cross the synapse and are received by the dendrites of another neuron
500
How is the central nervous system different than the peripheral nervous system?
The central nervous system is made up of the brain and the spinal chord. The peripheral nervous system is made up of the nerves outside the central nervous system. It sends messages between the central nervous system and other body parts.
500
What are the 4 blood types? Why is it important to know your blood type?
A, B, AB, O, and because if someone is injured and needs to get blood, they can only receive blood that is the same as theres. If they get the wrong type of blood, their blood can clot and oxygen will not get to the cells it needs to get to.
500
Describe the path of air in detail from the nose to the alveoli.
Air goes down the pharynx, moves through the laryx, then to the trachea (windpipe), then through smaller tubes called bronchi. Each bronchus does into each lung. In the lung, the bronchial tubes branches in many tubes. Oxygen rich blood can then circulate throughout the body.
500
Name the three parts of the eye that light passes through in the order that it travels from the outside of the eye to the retina.
Light enters through the cornea (clear layer) through the pupil (black circle in the center of the eye). The iris (colored part) controls how much light enters. The lens focuses light onto the retina at the back of the eye.
500
Describe the parts of a neuron, and what the function of each part is.
Dendrites, axons, synapses Dendrites - Extensions from the neuron cell body that take information to the cell body. RECEIVE INFO Cell body - the part of the cell that contains the nucleus. Axon - Takes information away from the cell body. Synapses- Sends information
