A function of the skeletal system is to act as a storage area for calcium true or false?
True, blood calcium is very tightly regulated there are two types of bone cells that will either take up excess calcium if blood levels get too high or break down bone to release calcium if blood levels get to low. Both of these bone cells are controlled by the endocrine system in the body.
What substances do bone cells take from the blood to keep the bone hard?
it takes calcium! it takes calcium!
Why do blood types differ?
Answer:Blood Type is a classification for some of the proteins (antigens) found on the red blood cells our bodies make. People who have "type A" blood also produce "Type A" antigens AND produce "Anti blood type B" antibodies. Same goes for someone who has blood "type B". They produce "Type B" antigens and produce "Anti blood type A" antibodies.When a person receives the 'wrong blood type' what is happening is that the persons own "Anti blood type antibodies" are attacking the new red blood cells because the new red blood cells have the protein saying they are "A" or they are "B" all over them.People who have blood type "AB" make BOTH antigen proteins on their red blood cells and they dont produce either of the 'anti blood type antibodies'. Since there are no antibodies there is nothing to fight with the red blood cells protein markers (aka antigens) so they do not have a bad reaction. They can get blood from anyone.Blood type O is not like blood type A or B and its even different than blood type "AB".The "O" means "Other". Even though the type of antigen protein their red blood cells have is 'other' than "A" or "B" they still produce the 'anti a' and the 'anti b' antibodies.So they should only ever receive blood from other "blood type O" donors.If you want to know how these types (and others) evolved, see Scientific American in the related link below.
Even though the cocentration of salt is higher in some gland-cells than in blood-cells the gland-cells can still take salt out of blood-cells this is an example of?
active transport
How can doctors determine positive or negative blood types.?
Doctors can determine positive or negative blood types by administering a test. The difference between positive and negative types is the presence of the RH factor. Positive blood types indicate the presence of the RH factor while negative blood types do not have this factor.

What substance do bone cells take from the blood to keep it hard?
Calcium and Phosphorus
How can you say bones are dynamic structure?
Bones are dynamic in the sense that they are constantly being broken down and built back up. When blood calcium levels are low, cells called osteoclasts break down bone matrix and release the calcium into the blood. When blood calcium levels are high, cells called osteoblasts take calcium out of the blood and use it the built bone matrix.
How long might those with high blood pressure have to take calcium channel blockers?
Calcium channel blockers are drugs that bind to cardiac muscle cells and prevent calcium from entering them. This decreases contraction and conduction of the heart, and a decrease of heart rate. This also decreases contraction of smooth cells around blood vessels, which relaxes and widens blood vessels, lowering blood pressure.
What is the clumping together of red blood cells when unlike incompatible types of blood are mixed is due to antibodies in the plasma and antigens on the?
On the surface of red blood cells Take A type blood, for instance. It has antigens against B type blood contact on its cell surface.
Which blood cells take oxygen around the body?
The red blood cells have that function.
What does blood take away from cells?
blood takes the impurities and carbon dioxide from the cells.
Why is it important for red blood cells to have hemoglobin?
Red blood cells carry oxygen, they then take this oxygen to the muscle cells to let the muscles respire, in doing this the muscles cells get more oxygen to work at their full potential. Having more red blood cells may be an advantage in this respect
What color blood cells bring oxygen to cells and take carbon dioxide away.?
the red blood cells
What do red blood cells take away from cells?
hello
What does it take to see red blood cells?
You need a microscope to see red blood cells.
