Episode 13 (CaW CB)

"Cardiac Arrest, Revival, and a Change" (心筋梗塞、蘇生、変化) is the 13th episode of the Cells at Work! CODE BLACK! anime adaption.

Plot
The body receives chest compressions and the heart fibrillates. The cells chant for the heart to work again except for a veteran red blood cell who is tired of working. The heart is shocked by a defibrillator and works again. The coronary artery gets a stent inserted to clear the blockage, allowing the blood to circulate again. The red blood cells deliver oxygen to all the body's cells, saving them. Afterwards, AA2153 reminisces about his life's journey and meets U-1196 as they note that the body has cleaned up its act. The body has stopped smoking, drinking alcohol, and eating bad food, so the body is cleaner and less stressed. U-1196 says AA2153 has matured and AA2153 says he always admired U-1196, making them blush.

After the credits, the body is pierced by a syringe that sucks blood cells into it, including AA2153 and U-1196. They wake up and are horrified to find themselves in a new body that is even dirtier than the last one previously was.
