(noun)

A region of the brain responsible for nervous control of cardiac output.

Examples of cardiovascular centre in the following topics:

  • Role of the Cardiovascular Center

    • The cardiovascular system plays a role in body maintenance by transporting hormones and nutrients and removing waste products.
    • The cardiovascular center forms part of the autonomic nervous system and is responsible for regulation of cardiac output.
    • The cardiovascular center can respond to numerous stimuli.
    • Baroreceptors that detect stretch can also signal to the cardiovascular center to alter heart rate.
    • Explain the role of the cardiovascular center in controlling blood pressure

  • Stress and Disease

    • The result can manifest itself in obvious illnesses such as ulcers, depression, diabetes, trouble with the digestive system, or even cardiovascular problems, along with other mental illnesses.
    • In depression, the transmission of noradrenaline is reduced from both of the principal noradrenergic centres.

  • Short-Term Neural Control

    • Neural regulation of blood pressure is achieved through the role of cardiovascular centers and baroreceptor stimulation.
    • Neurological regulation of blood pressure and flow depends on the cardiovascular centers located in the medulla oblongata.
    • They send impulses to the cardiovascular center to regulate blood pressure.
    • Other neural mechanisms can also have a significant impact on cardiovascular function.
    • Describe the role of baroreceptors and cardiovascular centers (ANS) in blood pressure control

  • Stress and Cardiovascular Disease

    • Cardiovascular disease has a number of behavioral risk factors, many of which are related to stress.
    • Cardiovascular disease has a number of behavioral risk factors, some of which are related to chronic stress.
    • Many researchers argue that the relationship between stress and cardiovascular disease is a combination of these factors.
    • Stress may lead to obesity and diabetes, which are both linked to cardiovascular disease.
    • However, managing one's stress levels and finding healthy outlets for stress is a crucial component for preventing cardiovascular disease.

  • Case study: gender discrimination exercises

    • Rosiglitazone is the active ingredient in the controversial type 2 diabetes medicine Avandia and has been linked to an increased risk of serious cardiovascular problems such as stroke, heart failure, and death.
    • In a nationwide retrospective observational study of 227,571 Medicare beneļ¬ciaries aged 65 years or older, it was found that 2,593 of the 67,593 patients using rosiglitazone and 5,386 of the 159,978 using pioglitazone had serious cardiovascular problems.
    • (a) Since more patients on pioglitazone had cardiovascular problems (5,386 vs. 2,593), we can conclude that the rate of cardiovascular problems for those on a pioglitazone treatment is higher.
    • (c) The fact that the rate of incidence is higher for the rosiglitazone group proves that rosiglitazone causes serious cardiovascular problems.
    • The table shows the relationship between cardiovascular problems and two types of treatment - Rosiglitazone and Piolitazone.

  • Blood Flow

    • Blood flow is the continuous running of blood through the cardiovascular system, which consists of the vessels and the heart.
    • Blood flow is the continuous running of blood through vessels in the cardiovascular system (the mammalian cardiovascular system is shown in ).
    • The cardiovascular system, which consists of blood vessels and the heart, helps to distribute nutrients, O2, and other products of metabolism.

  • Effects of Exercise on the Heart

    • Aerobic exercise promotes cardiovascular health, while physical inactivity is associated with increased morbidity and mortality.
    • Exercise has been shown to protect against nearly every type of chronic acquired cardiovascular disease.
    • Training for these events is done predominantly through cardiovascular exercise like running, swimming, and aerobics.
    • Exercise, along with a healthy diet, is effective at preventing chronic acquired cardiovascular diseases for several reasons.
    • About thirty minutes per day of cardiovascular exercise is recommended for most non-athletes who wish to maintain a healthy lifestyle.

  • Behavior and Environmental Influences on Health

    • However, if someone stops smoking the risks of developing diseases steadily decline, although gradually, as the damage to their body is repaired.The main health risks from tobacco smoking pertain to diseases of the cardiovascular system, in particular smoking is a major risk factor for: myocardial infarction (heart attack); diseases of the respiratory tract, such as Chronic Obstructive Pulmonary Disease (COPD) and emphysema; and cancer, particularly lung cancer and cancers of the larynx and tongue.
    • The current medical recommendation regarding being a moderate drinker is that it is "not only meaningless but also irresponsible" to become a moderate drinker if you don't already drink given that the many obvious health hazards of alcohol outweigh "the benefits of alcohol [which] are small and ill-understood" particularly when so many other cardiovascular treatments are available.
    • While cultural and scientific definitions of obesity are subject to change, it is accepted that excessive body weight predisposes to various forms of disease, particularly cardiovascular disease.
    • For example, Professor Thomas Sanders, the director of the Nutrition, Food & Health Research Centre at King's College London, emphasises the need for balance between activity and consumption:

  • Distribution of Lymphatic Vessels

    • Its functions include providing sites for certain immune system functions and facilitating plasma circulation in the cardiovascular system.
    • Afferent and efferent lymph vessels are also most concentrated in these areas so they can filter lymph fluid close to the end of the lymphatic system, where fluid is returned into the cardiovascular system.
    • Like cardiovascular capillaries, lymph capillaries are well distributed throughout most of the body's tissues, though they are mostly absent in bone or nervous system tissue.
    • In comparison to cardiovascular capillaries, lymphatic capillaries are larger, distributed throughout connective tissues, and have a dead end that completely prevents backflow of lymph.
    • That means the lymphatic system is an open system with linear flow, while the cardiovascular system is a closed system with true circular flow.

  • The Cardiovascular System

    • Both the cardiovascular system and the lymphatic system are susceptible to diseases caused by microorganisms.
    • Both the cardiovascular system and the lymphatic system are susceptible to diseases caused by microorganisms.
    • In the cardiovascular system, the heart, the blood vessels (arteries, capillaries, and veins), and the blood are targets of pathogens.
    • Two common cardiovascular diseases caused by infection with microorganisms are endocarditis and myocarditis.
