Blood vessels that carry blood back to the heart
What are veins?
When deoxygenated blood leaves the heart, where does it go?
What is when deoxygenated blood leaves the heart, it heads for the lungs to become oxygenated.
When you inhale, air travels through the following parts of the respiratory system: pharynx, nasal cavity, trachea, larynx, alveoli, bronchial tubes. List these parts in the order in which inhaled air passes through them.
What is nasal cavity, pharynx, larynx, trachea, bronchial tubes, alveoli
What makes up more than half of your blood?
What is blood plasma.
Where are bronchial tubes found, and what travels in them?
What is bronchial tubes are found in the lungs. Air travels through them.
Tiny, thin-walled blood vessels that allow the exchange of gases and nutrients between the blood and cells and are located between arteries and veins
What are Capillaries?
After entering the heart, the deoxygenated blood is then transferred to a second chamber. What chamber is that?
What is after filling the right atrium, the deoxygenated blood is pushed into the right ventricle.
What controls the volume of the sound produced by the vocal cords? What controls the pitch of the sound produced?
What is 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.
When deoxygenated blood is returning to the heart, into what chamber does it enter the heart?
What is right atrium
What is special about a four-chambered heart as compared to a three-chambered heart or a two-chambered heart?
What is a four-chambered heart is much more efficient than other kinds of hearts.
Blood vessels that carry blood away from the heart
What are Arteries?
When oxygenated blood comes into the heart, what chamber does it fill?
What is oxygenated blood that is returning to the heart fills the left atrium.
What are alveoli? What happens in the alveoli?
What is alveoli are small sacs at the end of tiny bronchial tubes. Oxygenation of blood takes place in them. The blood also gives up waste products there.
In what kind of blood vessels does the blood transfer oxygen to the cells and pick up wastes?
What are capillaries
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?
What is xylem.
What purpose does the heart serve?
What is the heart pumps blood throughout the circulatory system.
Once the oxygenated blood is back in the heart, it is then transferred to another chamber. What chamber is that?
What is after entering the left atrium, the oxygenated blood is dumped into the left ventricle.
What is hemoglobin and where is it found?
What is hemoglobin is a protein that carries oxygen. It is found in the red blood cells.
Which of the parts of the respiratory system contains the vocal cords?
What is larynx.
Name the three types of blood cells and their main job in the blood.
What is 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 blood clotting process.
What purpose do the lungs serve?
What is the lungs oxygenate the blood and allow the blood to get rid of carbon dioxide.
When oxygenated blood leaves the heart, through what artery does it travel first?
What is when oxygenated blood is leaving the heart, it is pumped out into the aorta
Where are blood cells produced?
What is blood cells are produced in bone marrow.
How many chambers are in a human heart? Name them.
What is the human heart has four chambers: the right atrium, left atrium, right ventricle, and left ventricle.
Most veins carry what kind of blood (oxygenated or deoxygenated)? Are there any exceptions to this general rule?
What is 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.
