What is the central nervous and the peripheral nervous system?
The CNS is made up of the brain and spinal cord. It processes incoming and outgoing messages. The peripheral nervous system connects all parts of your body to your CNS.
100
What is one function of the integumentary system?
Possible answers: Protect the inside of your body from infection/disease, regulate heat/body temp., keep moisture in, get rid of waste, feel the world around us
100
Why is it important to have capillaries everywhere in your body?
All the cells in your body need access to blood so that it can get oxygen and get rid of carbon dioxide.
100
What is this a picture of?
This is spongy bone.
100
Which muscles are involved in breathing? How do these muscles work?
The diaphragm and the rib muscles help you breathe. In order to inhale, the diaphragm contracts/pulls downwards and the rib muscles lift your rib cage upwards to expand the chest cavity. This allows the lungs to fill with air. When these muscles relax, they help to push the air out of your lungs.

What is a sensory neuron and a motor neuron?
A sensory neuron carries information from your senses (touch, feel, hearing, vision, and tasting) to the brain (the central nervous system). A motor neuron carries information from the brain to your muscles to move a part of your body.
200
What are the two main layers of your skin?
The epidermis is the top layer of your skin. It tends to be thinner than your dermis, the second main layer of skin. The dermis contains nerves, sweat glands, and hair follicles.
200
What is the function of heart valves?
They keep blood flowing in one direction by letting it go in one direction and closing if blood tries to flow backwards.

Name all of the bones seen in this picture.
scapula, the back of the clavicle, thoracic vertebrae, ribs, the top portion of the lumbar vertebrae and the bottom portion of the cervical vertebrae

Which structure in the respiratory system that helps us speak?
The larynx.
300
Oh no! I'm about to fall over! Which part of my brain helps to make sure that I stay upright?
The cerebellum.
300
Why does it hurt to pull on your hair but it doesn't hurt when you cut it?
Since hair itself does not have any nerves, we don't feel any pain, however, the hair follicle is found in the dermis near lots of nerves.

How do platelets stop bleeding?
Platelets clump together to form a plug around the damaged area. Then protein fibers form to create a blood clot. This eventually turns into a scab.
300
What would happen if somebody damaged the tendons in their elbow?
They may not be able to move their forearms because the tendons connect the biceps and tricep muscles to the radius and ulna.
300
What happens when a person has emphysema?
Their alveoli have eroded away so they cannot get as much oxygen as a person who has healthy alveoli.
400
What might be affected if I damaged the front part of brain?
There can be changes in: personality, judgement, attention, speaking, problem-solving, and memory.
400
Ouch! I got a paper cut! It's bleeeeeding!! Explain the structures under the skin that are affected.
A paper cut cuts through the epidermis and the dermis. It hurts because nerves are located in the dermis as well as blood vessels. Capillaries can get cut which is why paper cuts can bleed.
400
Why is blood type O considered the universal donor?
Because the red blood cells do not have A or B antigens.
400
What is the difference between skeletal muscle, cardiac muscle, and smooth muscle?
The skeletal muscles are attached to the bone. They can move both involuntarily and voluntarily. Cardiac muscle is only found in heart and it is involuntary. Smooth muscle is found in the digestive system and blood vessels. These are also involuntary.
400
How do the respiratory system and cardiovascular system work together?
The respiratory system brings in the oxygen into the body. The capillaries in the alveoli take in the oxygen and release carbon dioxide. The capillaries return the oxygen rich blood back to the heart via the pulmonary vein. The heart then distributes the oxygen-rich blood to the rest of the body.
500
I put my hand on a hot plate. Ouch! Explain what happens from the time I touch the hot plate to when I move my hand in terms of the sensory receptor, sensory neurons, spinal cord, brain, and motor neurons.
The sensory receptor feels the hot plate and sends an impulse via the sensory neurons to the spinal cord. At this point, one message is sent to the brain to process the pain, and one message is sent through the motor neurons to move your hand away.
500
What is this video showing? How does the body make this happen?
This video shows sweat coming out of pores. This happens when heat sensors cause a muscle to squeeze the sweat gland in the dermis and water comes out.
500
What is the path of blood in systemic circulation beginning with the left ventricle? Be specific.
The blood travels from the left ventricle out through the aorta to the rest of the body. Then it returns through the superior and inferior vena cava to the right atrium.
500
How do bones help muscles contract?
They store calcium which is needed in order for muscle cells to work.

Why does a person with asthma have trouble breathing? Look at this picture to help you.
A person with asthma have bronchioles that have constricted (or gotten smaller) and there is often mucus blocking the bronchiole.
