How do I put this in a for loop

labeledImage = bwlabel(originalImage);

blobMeasurements = regionprops(labeledImage, 'EulerNumber','Area');

numberOfBlobs = size(blobMeasurements, 1);

figure;

imshow(I);

enumbers = [blobMeasurements.EulerNumber];

want_blob = enumbers ==0;

wanted_blobs = blobMeasurements(want_blob);

wanted_areas = [wanted_blobs.Area];

I have done the above to find the area of closed contours in a ball. I have 9 balls in a picture how do I put the above code in a for loop? for the 9 different balls
