Larger organisms develop cells that each do very specific chores. They depend on other cells to deliver the required oxygen and nutrients. The circulatory system allows the cells that are in charge of providing these required substances to the other cells.

What is true about earth systems?
It is a large region of multiple organisms 👌
Are there differences between major groups of organisms to how fast they respire?
Yes, respiration rates for large organisms are generally higher compared to small organisms. Large organisms require more oxygen than small organisms.
Definition of circulatory systems?
circulatory system is a large organism involving flow of fluid through the tissue and organs allowing the transport and exchange of substances such as nutrients,oxygen and waste products
Why have large organisms devolped systems like the respirtory system?
because they need to breath!
What nutrients help support the functioning of large molecules in organisms?
Organisms require water, vitamins, minerals, and salts to support the functioning of large molecules. - "California focus on physical science" science textbook.
Is your circulatory system open or closed?
A humans circulatory system is closed. Large creatures tend to have a closed system, while smaller creatures like insects and crustaceans have open circulatory systems. Closed is when there are vessels and the blood stays there. Open is when blood floats around the body. Hope it helps:)
Disadvantages of mainframes?
Mainframe computer systems have multiple disadvantages. They require a large amount of power, specialized support personnel, and special cooling systems to keep them from overheating.
Do all organisms must have organ systems?
No. Organ systems only develop in larger, complex organisms. E.g. amoeba, a single celled organism, is small enough that all its needs can be obtained by the relevant organelles through diffusion. A dog, a large multi-cellular organisms, needs a system to deliver its requirements to the necessary tissues .
What type of compounds are most nutrients and why does your body need them?
Organisms require water, vitamins, minerals, and salts to support the functioning of large molecules
Is earthworms unicellular?
No. An example of unicellular organisms would be bacteria. Earthworms are multicellular and contain organs and organ systems. Unicellular organisms are typically invisible to the naked eye except when in large groups (such as yeast).
What is the difference between a closed and an open circulatory system?
In an open circulatory system, a tubular heart pumps hemolymph into a hemocoel (a system of interconnected sinuses), where chemical exchange can occur with the "bathed" tissues. The hemolymph diffuses back to the heart. This creates a sluggish blood flow because of low pressure & low oxygen content, resulting in low efficiency. In a closed circulatory system, a muscular heart pumps blood into large vessels that branch into smaller vessels that course through the organs. The blood is confined to vessels and are distinct from the interstitial fluid. Basically, an open circulatory system is somehow connected to the environment, while the closed circulatory system is just confined in the animal's body.
What comes after the small intestine the villi or the circulatory system?
The large
