Without the circulatory and respiratory systems, human bodies would not survive. Both systems play major roles in providing our bodies with what they need. They work individually as well as together to keep us alive and healthy, Which statements describe functions of the circulatory system?

Part of this system filters air as it enters the body.
Oxygen is delivered to cells throughout the body by this system.
Nutrients are delivered to organs through this system.
This system takes in oxygen from air outside the body.
This system removes carbon dioxide from organs and delivers it the lungs.
Carbon dioxide exits the body through this system.
This system's organs passes oxygen into the bloodstream.
This system plays a major role in fighting infections.
please help im not doing so hot in science and there are several answers not just 1 but i REALLY need help please help me

I think I might know some oxygen is delivered to the cells throughout the body by this system I think by one of the arteries nutrients are delivered organs through this system by the red blood cells this system removes carbon dioxide from the organs to the lungs by one of the veins or arteries this system organ passes oxygen into the bloodstream I think by the pulmonary artery the system plays a major role in fighting infections by the white blood cells

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.

they both go up but then go back down. they both end lower than they started. lastly, they both are competitive/the second on.
