The Respatory System . i Guessed . :)
Lungs play a vital role in the cardiovascular system because they provide the oxygen to the blood stream and remove carbon dioxide.
The cardiovascular system's main organ is the Heart. The other organs associated are blood vessels. The cardiovascular system is responsible for pumping and circulating the blood. The lungs play a vital role in the cardiovascular system, however; they are not technically part of this system even though a lot of people think they are. The respiratory system includes the pharynx, larynx, trachea, bronchi, lungs and diaphragm. These are the organs used for breathing.
The organs involved in the cardiovascular system are the lungs, the heart and the brain. Without any one of those organs working properly you can die or live poorly. The blood vessels are the roadways for the blood to travel through out the body but are not to be confused with organs. They are tubes that do a fantastic job but not organs as some people believe. The trachea is the windpipe not an organ as some have mistaken also.
simply dividing one is systemic circulation and 2nd is pulmonary circulation....systemic is providing oxygenated blood to body,while pulmpnary is providing oxygenation to blood
The lungs are shared between the respiratory and cardiovascular systems. The lungs are responsible for exchanging oxygen and carbon dioxide during respiration, but they also play a role in delivering oxygen to the bloodstream and removing carbon dioxide from it as part of the cardiovascular system.
The cardiovascular system (The Heart) pumps blood throughout the body. Without the Cardiovascular system, humans would be dead.
The body system primarily linked with a heart attack is the cardiovascular system. This system includes the heart, blood vessels, and blood, and is responsible for delivering oxygen and nutrients to tissues throughout the body. A heart attack occurs when the blood flow to a part of the heart muscle is blocked, often due to a buildup of plaque in the coronary arteries, leading to potential damage or death of heart tissue. Other systems, such as the endocrine system (which influences risk factors like cholesterol and blood pressure), also play a role in heart health.
Normal impulse conduction
thymus
the heart pumps the blood round the body
These serve in transporting blood between heart, organs, and muscles. Arteries usually leave the heart and transports blood to the body(systematic circulation) or to the lungs(pulmonary circulation).
The parasympathetic nervous system helps regulate heart rate by slowing it down. It works in opposition to the sympathetic nervous system, which speeds up heart rate.
