What type of stimulus do photoreceptors receive? Which of our senses are they associated with?
Light; vision
What are neurons and what do they do?
Neurons are the cells that make up our brain and nerves. They send electric messages to and from the brain.
The smallest structure that could be considered living is a ______________.
cell
Why is it important to give someone who is not breathing and has no pulse chest compressions as soon as possible?
Doing chest compressions allows blood to continue flowing in the body. Blood contains the oxygen and nutrients needed for all the cells in the body to survive.
What is the main purpose of aerobic cellular respiration?
To make/release usable energy for the cells of living organisms.
What type of stimulus do mechanoreceptors receive? Which of our senses are they associated with?
mechanical/physical; touch and/or hearing
How does a message travel from one neuron to the next?
A. It passes from the dendrites of one neuron to the axon of the next.
B. It passes from the cell body of one neuron to the axon of the next.
C. It passes from the axon of one neuron to the cell body of the next.
D. It passes from the axon of one neuron to the dendrites of the next.
E. It passes from the dendrites of one neuron to the cell body of the next.
D. It passes from the axon of one neuron to the dendrites of the next.
Student A says, "A disease that affects the circulatory system can also affect the digestive system."
Student B says, "If you have a circulatory system problem, it can affect your heart but nothing else."
Which student is correct and why?
Student A because all of the human body systems are connected in some way. If one is affected, they can all be affected.
OR
Explain how the circulatory system directly affects the digestive system.
Which body systems provides structure and protection and allows the body to move?
What two resources are needed for aerobic cellular respiration to occur?
Oxygen and Nutrients
What type of stimulus do chemoreceptors receive? Which of our senses are they associated with?
chemicals; smell and/or taste
The time it takes between sensing a stimulus and responding to it is called what?
Reaction Time
Which body system gets rid of waste?
Excretory System
Which body system transports oxygen and nutrients to all the cells in the body?
Circulatory System
What are the waste products of aerobic cellular respiration?
Water and Carbon Dioxide
What do our sensory receptors create and send to the brain after sensing a stimulus?
Why are neurotransmitters important?
They travel across the gap (synapse) between neurons and allow electric messages to continue traveling to or from the brain.
Which body system breaks food down into nutrient molecules?
Digestive System
Which body system takes in oxygen and gets rid of carbon dioxide.
Respiratory System
How do plant cells get the oxygen and glucose they need for aerobic cellular respiration?
Photosynthesis
Which of the following statements describes what memories are most accurately:

B. Complex electric signals that communicate
C. Complex networks of neurons
D. Weakened connection between synapses in the brain
E. A mixture of chemicals in the brain
C. Complex network of neurons
