Answer to Question #332699 in Cell Biology for Linken

Question

How do the digestive system, circulatory system and respiratory system work together

Answer 1

The respiratory system brings in oxygen from the air and eliminates carbon dioxide. Digestive system breaks down complex substances into smaller ones: glucose, fatty acids and amino acids- and then it absorbs water and nutrients(after breakdown) from the food we eat. The circulatory system than distributes and delivers oxygen, water, and nutrients to cells throughout your body.
