blood vessels that carry blood back to the heart
blood vessels that carry blood away from the heart
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 blood to release carbon dioxide
what purpose dose the heart serve
the heart pumps blood throughout the circulatory system
how many chambers are there in the human heart. name them
4 chambers. left ventricle, right ventricle, right atrium, and left atrium
what is special about a four chamber heart as compared to a three chambered or a two chambered heart
it is special because it seperates oxygenated blood from deoxygenated blood
in what kind of blood vessels does the blood transfer oxygen to the cells and pick up wastes
when deoxygenated blood is returning to the heart into what chamber does it enter
the right atrium
after entering the heart the deoxygenated blood is then transferred to a second chamber what chamber is that
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
the left atrium
once the oxygenated blood is back in the heart what chamber is it transferred to
when oxygenated blood leaves the heart what artery does it travel first in
most veins carry what kind of blood? are there any exceptions to this general rules of thumb?
Veins usually carry deoxygenated blood, because they are carrying it back to the heart to be pumped into the lungs.
X yes because pulmonary viens contain oxygenated blood
name three types of blood cells and their main job in the blood.
red blood cells: transport oxygen from the lungs to tissues of the body
white blood cells
: protects the body from diseases
: help with coagulation when a blood vessel is injured
what makes up more than half your blood
what is hemoglobin and where is it found
its a protein that carries oxygen and gives red blood cells its red color
where are blood cells produced
what are aveoli? what happens in the alveoli
Alveoli are little sacs at the end of tiny bronchial tubes that are covered with capillaries . Oxygenation of blood takes place in them. The blood also gives up waste products there.
what kind of blood vessels surround the alveoli
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 respitory system list the order in witch in haled air passes through them
nasal cavity, pharynx, larynx, trachea, bronchial tubes, alveoli
which of parts listed in the other problem contains the vocal cords
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. the tightness of your volcal cords controls the pitch
a sample of fluid is taken from a tube from a plant . if its mostly water which was it taken from a xylem of a phloem
