Answer:

Sorry for such a late answer, but I think you make it seem fun. Tell them it's connected with the heart and like a sponge, the heart "soaks the blood up" and when you squeeze the sponge it gushes out. That's all I've got.

Hey!

I think this is absolutely wonderful! I always have a hard time understanding why people don't give each other a chance. Why do so many break ups and divorces exist. This is actually what I think when I see or hear the word "relationship". Only, sometimes the relationship can be harmful for you and it can get toxic, so you should be aware of that. Otherwise this is lovely, definitely not too emotional. Both people in the relationship must play their part, and there should always be a sense of trust between them.

Sorry, this got to long! :D

Composed of a phospholipid bilayer with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules and regulates the movement of substances in and out of cells.glucose
