The circulatory system is a closed loop system. It starts and ends at the heart. The blood doesn't leave the system and is pumped back to the heart to start the journey of the cycle again. The circulatory system runs throughout the body to supply blood to all parts.
No, Platyhelminthes lacks a circulatory system and a respiratory system.
Phylum Cnidaria (e.g. jellyfish, corals) have an open circulatory system. This means that their circulatory fluid, called coelomic fluid, bathes their internal organs directly in nutrients and oxygen. There is no distinction between blood and interstitial fluid in an open circulatory system.
They both work to provide oxygen to the cells. The respiratory system provides air to the circulatory system. The the blood from the circulatory system delivers oxygen to the cells. For more help search on the Internet. :)
Cnidarians have a hydrostatic skeleton, this means the body is supported by the liquid that fills it. They have a central cavity surrounded by two layers of tissue, the ectotherm and endotherm. The jellyfish has no circulatory system but a nervous system. It has some muscle fibers controlled by the network of nerves. IT has no brain to coordinate its reactions.
Agnatha, such as lampreys and hagfish, have a two-chambered heart. The heart consists of an atrium and a ventricle, which pump blood through the circulatory system.
it works like our circulatory system
The respiratory system works directly with the circulatory system when to oxygenate blood.
Circulatory systems operates blood circulation
It works with the circulatory system because nutriants , vitamins, and food follow through our blood
The circulatory system works with digestive system to circulate the nutrients to all the body parts. The nutrients are digested and absorbed by the digestive system. The circulatory system circulates the nutrients throughout the body.
The heart
Everything in the circulatory system works together to remove waste from the blood. The circulatory system provides the excretory system with the blood to be cleaned.
The circulatory system distributes oxygen to body tissues as it works with the respiratory system. It also helps bring carbon dioxide back to the lungs so that it can be expelled.
Respiratory system works with digestive system ,circulatory system ,excretory system (indirectly through circulatory system...
Yes! Circulatory system.
It works with the respiratory system especially the lungs.
it works by helping to fight germs
