i dont think thats correct
I apologize for the incorrect response. Blood cells and stomach cells are not similar in terms of their function. Blood cells primarily serve to transport oxygen, nutrients, hormones, and waste products throughout the body, while stomach cells are responsible for producing digestive enzymes and acid to break down food. Thank you for pointing out the error.
so which answer is it then
I apologize for the confusion. The correct answer is: Both secrete enzymes. Stomach cells secrete enzymes such as pepsin and gastric lipase, which aid in the digestion of proteins and lipids in the stomach. Blood cells, specifically certain types of white blood cells, also secrete enzymes as part of their immune response. I apologize for the incorrect response earlier. Thank you for bringing it to my attention.
