Question
Answer
Transports materials to and from your cells.   Cardiovascular system  
🗑
Made of three parts heart, blood and blood vessels.   Cardiovascular system  
🗑
Body contains 5 liters(L).   blood  
🗑
Made of cell, cell parts and plasma(the fluid part of the blood).   blood  
🗑
Most abundant cells in the body.   red blood cells  
🗑
Contains Iron(Fe) and O2 bonds to the FE.   red blood cells  
🗑
b/c. they are flat there is more surface area to carry more O2.   red blood cells  
🗑
Made in bone marrow.   red blood cells  
🗑
Contain hemoglobin which makes cells red and transport oxygen(O2).   red blood cells  
🗑
Destroy pathogens-bacteria, viruses and other microscopic particles that make you sick.   white blood cells  
🗑
Some engulf pathogens.   white blood cells  
🗑
Some release antibodies which destroy pathogens.   white blood cells  
🗑
Some engulf body cells that are dead or damaged.   white blood cells  
🗑
Made in bone marrow.   white blood cells  
🗑
If the cells are lacking in iron not as much of this will be transported in the body.   oxygen  
🗑
Only live 5 – 10 days.   platelets  
🗑
Clump together when there is a cut less blood is lost.   platelets  
🗑
Size of your fist.   heart  
🗑
Pumps oxygen poor blood to the lungs and oxygen rich blood to the body.   Heart  
🗑
Upper chambers of the heart.   Atrium  
🗑
Lower chambers of the heart.   Ventricle-  
🗑
Located between atria and ventricles; prevent blood from going backwards.   valves  
🗑
Receives blood from the body.   Atrium  
🗑
Push blood out to the body.   Ventricles  
🗑
______ side of heart receives blood low in O2 and high in CO2.   Right  
🗑
______side of heart receives blood high in O2 and low in CO2.   Left  
🗑
Hollow tubes that transports blood.   blood vessels  
🗑
Direct blood away from the heart and to the body.   arteries  
🗑
Blood vessels with thicker walls.   arteries  
🗑
Smallest blood vessels in the body.   capillaries  
🗑
Cells must pass through one at a time.   capillaries  
🗑
Direct blood back into the heart.   veins  
🗑
Force exerted by blood on the inside walls of a blood vessel.   blood pressure  
🗑
Normal is 120/80.   blood pressure  
🗑
Inside large arteries when ventricles contract.   systolic pressure  
🗑
Inside arteries when ventricles relax.   diastolic pressure  
🗑
Chemicals on surface of RBC.   antigens  
🗑
Chemicals in plasma that bind to antigens not found on their RBC’s.   antibodies  
🗑
Has A antigens and B antibodies.   blood type A  
🗑
Has B antigens and A antibodies.   blood type B  
🗑
Has AB antigens and not antibodies.   blood type AB  
🗑
Has no antigens and AB antibodies.   blood type O  
🗑
Its RBC’s do not have antigens so recipients’ blood will not attack it.   Universal donor Type O  
🗑
B/C they do not produce antibodies against any antigens on the donor’s blood cells.   Universal Recipient Type AB  
🗑


   

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
 
To hide a column, click on the column name.
 
To hide the entire table, click on the "Hide All" button.
 
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
 
Or sort by any of the columns using the down arrow next to any column heading.
