*Apologia: General Science - Module 14
Blood vessels that carry (de-oxygenated) blood back to the heart
Blood vessels that carry (oxygenated) blood away from the heart
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 purpose do the lungs serve?
Oygenate the blood and allow the blood to get rid of carbon dioxide.
*What purpose does the heart serve?
Pumps blood throughout the circulatory system
*How many chambers does the human heart have? Name them.
*What is special about a four-chambered heart as compared to a three-chambered heart or a two-chambered heart?
A four-chambered heart is much more efficient
*In what kind of blood vessels does the blood transfer oxygen to the cells and pick up wastes?
*Put the following chambers of the heart in order if deoxygenated blood is coming in through the vena cava: left atrium, right ventricle, left ventricle, right atrium
*When deoxygenated blood leaves the heart, where does it go?
*When oxygenated blood leaves the heart, through which large artery does it travel first?
*Blood rich in oxygen is _____ blood. What blood vessel carries it?
oxygenated; majority of arteries carry this type of blood
*Blood that doesn't have much oxygen is _____ blood. What blood vessel carries it?
deoxygenated; majority of veins carry this type of blood
*What is the exception to the rule that most veins carry deoxygenated blood?
pulmonary veins; They take oxygenated blood back to the heart (from the lungs), so it can be pumped to the rest of the body.
*Name the 3 types of blood cells and their main job in the blood.
red blood cells; carry oxygen to the other cells of the body
white blood cells; fight disease-causing organisms
platelets; aid the blood clotting process
*What makes up more than half of your blood?
The pale, yellowish liquid part of the blood
*What is hemoglobin and where is it found?
The protein in red blood cells that carries oxygen
*Where are blood cells produced?
In bone marrow
*What kind of blood vessels surround the alveoli?
*What are alveoli? What happens in the alveoli?
small sacs at the end of tiny bronchial tubes; oxygenation of blood takes place in them and the blood also gives up waste products there
*Where are bronchial tubes found, and what travels in them?
In the lungs
The tubes carry air
*Put the following parts of the respiratory system in order when inhaled air passes through them: pharynx, nasal cavity, trachea, alveoli, bronchial tubes
*Which respiratory part contains the vocal cords or "voice box?"
*What controls the volume of the sound produced by vocal cords? What controls the pitch of sound produced in your vocal cords?
The amount of air that passes over the vocal cords controls the volume while 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?
*What cells aid in blood clotting? What exactly is blood clotting?
Blood clotting is the process by which blood seals wounds to keep it from leaking out an injured artery.
*Why can't a nose be 12 inches long?
Because then it would be a foot!
*Two blood cells met and fell in love....
but alas, it was all in vein!
