Nervous System
What are the parts of the central nervous system?
The Brain and the Spinal Cord
What do our arteries and veins do?
Arteries bring blood AWAY from the heart, and veins bring blood towards the heart. Keep in mind, not all arteries carry oxygenated blood, and not all veins carry deoxygenated blood!
The respiratory system primarily takes in...
The respiratory system primarily gets rid of...
Carbon Dioxide
Where does the majority of mechanical digestion occur?
Your mouth!
What vocabulary word talks about the process through which a living system remains in balance?
Hint: It's not equilibrium!
Homeostasis
What are the parts of the peripheral nervous system?
The Somatic and Autonomous Nervous Systems, or - At the very least - All nerves outside of the brain and the spinal cord.
What do our red blood cells do?
They contain hemoglobin, which helps us transport our oxygen.
Which muscle in our body controls exhalation and inhalation by contracting and relaxing?
The Diaphragm
Where does the majority of nutrient absorption occur?
The small intestine
Name the three major organs of the excretory system!
Kidneys, liver, skin
How does myelin increase the speed of the action potential as it travels along a neuron?
What is the purpose of our capillaries?
Our capillaries largely assist in the exchange of important nutrients or gasses with our cells, given that their walls are very thin.
What process does our body use oxygen for, and how does that process use it?
Cellular Respiration uses oxygen in order to create ATP, especially using it during the electron transport chain (that last part isn't necessary for full points, but encouraged)
What process allows food to move through the digestive tract?
Peristalsis
What is our nitrogenous waste called?
Bonus for Double: How is this waste typically excreted along with other wastes and excess water?
Urea
Bonus: Urine
What do our motor and sensory neurons do?
Our sensory neurons send signals from our sensory organs to our brain, and the motor neurons allow the body to move around and our brain to control us.
DAILY DOUBLE:
What is the primary purpose of the circulatory system, and how do its parts accomplish this?
Capillaries!
What is the function of the villi?
These hair-like cells function with nutrient absorption within the small intestines!
What happens to useful substances that pass through our kidneys and near the glomerulus?
They are reabsorbed so that they aren't wasted.
How do the folds and grooves in our brain help us?
They increase the surface area of the brain, effectively leaving room for more neurons and interconnectivity with the parts of our brains.
The heart pumps both oxygenated and deoxygenated blood, but it can't do this alone. It also moves because of the...
Movement of the skeletal muscles and your breathing!
On the board, draw and label the path of oxygen as it makes its way down into the lungs!
Student answers may vary.
Draw out and label the path of food as it moves through your digestive system!
DOUBLE points if you can talk about how you chemically or physically digest food in each portion!
Student answers may vary!
The excretory system helps filter the toxins out of our blood, and all of our blood eventually goes through various organs like the kidneys or the liver to get rid of waste materials that would normally harm our body at higher concentrations.
