Episode 11

"Heat Stress" (熱中症) is the eleventh episode of the Cells at Work! anime. It's based on the sixth chapter of the manga, which has the same title.

Synopsis
The cells experiences a heat wave after a heat stroke depletes the supply of fluids inside. To make matters worse, a bacillus cereus bacterium invades the body.

Plot
The body is under an extreme heat wave causing a major drought. AE3803 and her senior AA5100 walk through the veins noting how hot it is. However, AA5100 is optimistic that the heat will settle soon enough from the hidrosis. Just then U-1146 appears and immediately disposes of the bacteria. Although U-1146 is noticeably hot in his clothing, he can’t take it off due to his job restrictions.

At a resting area, the cells wait for the epidermis to start, but MI3477 states how strange it is that hidrosis has started, but not epidermis. Because of the sweltering heat the Red Blood Cells start moving again in order to help regulate the heat. Traveling down a dark and cramped tunnel, the body succumbs to Vertigo, which was caused by “Heat Stroke”. Appearing from a hole in the wall, is a bacteria known as Bacillus Cereus. It seemingly was going to fight against U-1146, but instead flees in order to hide until the body weakens enough so it can spread. U-1146 chases after it leaving behind AE3803 and her senior AA5100 with some Platelet.

In his pursuit of the Bacillus Cereus, U-1146 calls for back up and U-4989 and U-2048 appear to help. They, however, fail to stop the Bacillus Cereus and it taunts U-1146 and leads him on a chase until the White Blood Cell collapses due to Heat Stroke. Taking advantage of this, Bacillus Cereus continue taunting the unfortunate U-1146 by pouring tea on the ground in front of him.

Meanwhile, in the sweat command center, an order is given to pump the Osmotic pressure to circulate the water to cause sweat. This, however, is impossible due to the low sodium levels, which would cause the body to become dehydrated. Elsewhere, the weak and beaten U-1146 is easily overpowered by Bacillus Cereus, who grabs U-1146 and shows him the city as parts of it go up in flames. He then throws U-1146 off the cliff who manages to latch on with the help of his knife. Using his tendrils to attack U-1146, Bacillus Cereus attacks him and proclaims there’s nothing he can do. Finally, U-1146’s grip loosens enough that he falls off the cliffside and Bacillus Cereus relishes the fact as no one can stop him.

All hope is seemingly lost when a needle "pierces" the skies as the body receives a fluid transfusion, returning the body's hydration back to normal. As Bacillus Cereus tries to make sense of what's happening, U-1146 emerges from behind and grabs his tail, much to the bacteria's horror. He brutally kills the bacteria, with AE3803, AA5100 and the Platelets watching the scene from afar. After cleaning up the mess, AE3803 takes him along to cool down.

Error





 * 1) When the vertigo symptom occurs, a female red blood cell wears AE3803's hat. At the same time, AE3803 seems to wear her own hat, though.
 * 2) When the vertigo symptom occurs, CA6896 seems to wear his hat just like in manga. But, in the next closeup scene, he didn't wear his hat.
