What are two organ systems that work together?

Answer 1

Respiratory and Circulatory. The heart pumps the unoxygenated blood to the capillaries (the veins with such a thin wall that oxygen can pass right through it into the bloodstream, so small, in fact, that only one red blood cell can fit into the capillary at a time), and oxygen passes through the alvioli (little balls that look kind of like clusters of grapes, part of the lung), through the capillary wall, into the bloodstram.

Answer 2

The respiratory and circulatory systems work together to provide oxygen to the body's cells and remove carbon dioxide waste. The nervous and muscular systems also collaborate to enable movement and coordination throughout the body.

Answer 3

The nervous and endocrine systems control digestion.

Answer 4

The endocrine and nervous systems work closely together to control the processes of the body.

Answer 5
