Q

true or false: organ systems work alone to maintain homeostasis

A

false: they work together to maintain homeostasis (ex… the digestive system takes food and breaks it down into nutrients, circulatory system transports nutrients throughout the body.

Q

what are the serous membranes

A

continuous membrane that lines the inside of the body cavities and the outside of the internal organs.

46
Q

what are the serous fluid

A

lubricating fluid that reduces friction and provides cushion to the organs.
