What two (or more) systems are involved in blushing and how are the systems involved in blushing?

sorry for asking questions but i really need : (

You can't believe the words that have just come out of your mouth. You certainly didn't mean to insult the woman in line ahead of you, but it's too late now. What business is it of yours how many chicken nuggets she orders? She's staring at you angrily. You feel a sudden jolt as your heart rate increases. You have a coppery taste in your mouth, and your cheeks begin to feel warm. You, my friend, are embarrassed, and you're blushing because of it.

Blushing and embarrassment go hand in hand. Feeling flushed is such a natural response to sudden self-consciousness that if it weren't part of an emotionally crippling experience, it could almost be overlooked. But blushing is unique, which is why scientists want to know more about blushing. While the psychology of blushing remains elusive, we do understand the physical process involved. Here's how it works.   I hope this helps :)

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
