A.
contracts to move substances through the body
D.
breaks down food to acquire nutrients
        
             
        
        
        
That would be D. Isovolumic contraction 
As the name states during ISOvolumic contraction the volume of the ventricles doesn’t change and stays the same so no blood enters or leaves the ventricles. The thing that changes is the pressure of the ventricles that increases. 
I can explain the process more if u want in the comments:)
        
             
        
        
        
The answer is d. Ingestion, digestion, absorption, elimination.
There are 4 phases of the digestive system function:
1. Ingestion - the process of the food entering the mouth. 
2. Digestion - the process of breaking the food into small particles.
3. Absorption - the process of the absorbing small food particles into the blood from the intestines.
4. Elimination - is the process of removing the waste out of the body.
