The circulatory system is an organ system that passes nutrients (such as amino acids and electrolytes), gases, hormones, blood cells, etc. to and from cells in the body to help fight diseases and help stabilize body temperature and pH to maintain homeostasis.
This system may be seen strictly as a blood distribution network.
The circulatory system can be damaged by disease or injury. One of the most common diseases of the system is arteriosclerosis, which results from the accumulation of fatty deposits in the arteries. Such deposits stiffen and thicken the walls of the arteries. As a result, the flow of blood is restricted. In some cases, blood clots develop in vessels affected by arteriosclerosis. Such clots may lead to a heart attack or a stroke, a condition in which the brain does not receive enough blood.
Another disease, hypertension, commonly called high blood pressure, is often associated with arteriosclerosis. Hypertension makes the heart work harder and may lead to such complications as a heart attack, a stroke, or kidney failure.
Treatment for arteriosclerosis and hypertension includes rest, exercise, and changes in the diet. Doctors may prescribe various drugs to lower the blood pressure, strengthen the heart, or prevent infection and blood clots. In extreme cases, a surgeon may remove clots or replace one or more diseased blood vessels.
Other disorders of the circulatory system result from damage or defects in the heart or blood vessels. For example, rheumatic fever may harm or destroy the valves that control the flow of blood through the heart. Incomplete development of the heart or its blood vessels before birth may produce defects called congenital heart disorders. Some cases of damage or defects can be corrected by surgery.

Identify which type of circulatory system that a cephalopod develops?
Cephalopods, such as octopuses and squids, have a closed circulatory system. This system consists of a heart that pumps blood through a series of vessels for efficient distribution of oxygen and nutrients to tissues and organs.
Do arthropods have a open circulatory system?
Yes, most arthropods have an open circulatory system, which means that their blood, called hemolymph, directly bathes their tissues. This system is less efficient at transporting oxygen compared to closed circulatory systems found in vertebrates.
Which body system do you think would be most involved in an addiction?
i think its the circulatory system
The most common route of central nervous system invasion by pathogens is through?
The most common route of central nervous system invasion by pathogens is through the bloodstream, crossing the blood-brain barrier. This allows pathogens to enter the brain and spinal cord and cause infections such as meningitis and encephalitis.
Is the bivalves circulatory system open or closed?
Bivalves have an open circulatory system, where blood flows freely within the body cavity instead of through a closed network of vessels. Oxygen and nutrients are distributed to the tissues as the blood bathes them directly.
