How does the Respiratory & Circulatory Systems work together to maintain homeostasis?
O2 diffuses in the blood and is carried throughout the body through the circulatory system
How does the Digestive & Circulatory Systems work together to maintain homeostasis?
Nutrients get transported by the Circulatory System
How does the Endocrine & Circulatory Systems work together to maintain homeostasis?
The Endocrine System produces hormones & the Circulatory System transports them to targeted cells
