Define Veins
Blood vessels that carry blood back to the heart
Define Arteries
Blood vessels that carry blood away from the heart
Define Capillaries
Tiny, thin-walled blood vessels that allow the exchange of gases and nutrients between the blood and cells
What purpose do the lungs serve?
The lungs oxygenate the blood and allow the blood to get rid of carbon dioxide
How many chambers are there in a human heart?
The human heart has four chambers
Name the chambers in a human heart?
The human heart has four chambers: the right atrium, left atrium, right ventricle, and left ventricle.
When deoxygenated blood is returning to the heart, into what chamber does it enter the heart?
Deoxygenated blood comes into the heart through the vena cava and gets dumped into the right atrium.
After entering the heart, the deoxygenated blood is then transferred to a second chamber. What chamber is that?
After filling the right atrium, the deoxygenated blood is pushed into the right ventricle.
When deoxygenated blood leaves the heart, where does it go?
When deoxygenated blood leaves the heart, it heads for the lungs to become oxygenated.
When oxygenated blood comes into the heart, what chamber does it fill?
Oxygenated blood that is returning to the heart fills the left atrium.
Once the oxygenated blood is back in the heart, it is then transferred to another chamber.
What chamber is that?
After entering the left atrium, the oxygenated blood is dumped into the left ventricle.
When oxygenated blood leaves the heart, through what artery does it travel first?
When oxygenated blood is leaving the heart, it is pumped out into the aorta.
Most veins carry what kind of blood (oxygenated or deoxygenated)? Are there any
exceptions to this general rule of thumb?
Veins usually carry deoxygenated blood, because they are carrying it back to the heart to be pumped into the lungs. There are exceptions. The pulmonary vein, for example, carries oxygenated blood to the heart from the lungs. You need not know the name of the exception.
Name the three types of blood cells and their main job in the blood.
The red blood cells carry oxygen to the other cells of the body. The white blood cells fight disease-causing organisms, and the blood platelets aid the coagulation process when a blood vessel is injured.
What makes up more than half of your blood?
More than half of your blood is blood plasma.
What is hemoglobin and where is it found?
Hemoglobin is a protein that carries oxygen. It is found in the red blood cells.
Where are blood cells produced?
Blood cells are produced in bone marrow.
What are alveoli? What happens in the alveoli?
Alveoli are small sacks at the end of tiny bronchial tubes. Oxygenation of blood takes place in them. The blood also gives up waste products there.
What kind of blood vessels surround the alveoli?
Capillaries surround the alveoli, since that’s where the blood gets oxygen and releases wastes.
Where are bronchial tubes found and what travels in them?
Bronchial tubes are found in the lungs. Air travels through them.
When you inhale, air travels through the following parts of the respiratory system:
pharynx, nasal cavity, trachea, larynx, alveoli, bronchial tubes. Which of the parts in this list contains the vocal cords?
Vocal cords are found in the larynx
What controls the volume of the sound produced by the vocal cords? What controls the pitch of the sound produced?
The amount of air that passes over the vocal cords controls the volume of the sound, and the tightness of the vocal cords determines the pitch.
A sample of fluid is taken from a tube within a plant. If it is mostly water, which was it taken from: a xylem or phloem tube?
The xylem transport water up the plant. The phloem transport food down the plant. Thus, this sample was taken from the plant’s xylem.
