- "The blood circulatory system is a system of organs that includes the heart, blood vessels, and blood which is circulated throughout the entire body of a human or other vertebrate."
This topic covers the structure and function of the heart and blood vessels, including the mechanics of circulation and the various types of blood cells.
Heart anatomy: The structure and function of the heart, including chambers, valves, and blood vessels.
Blood vessels: The different types of blood vessels, including arteries, veins, and capillaries, and their role in the transport of oxygen and nutrients throughout the body.
Blood flow: The processes that regulate blood flow through the cardiovascular system, including the cardiac cycle, blood pressure, and vascular resistance.
Cardiac output: The amount of blood the heart pumps each minute, determined by stroke volume and heart rate.
Cardiac muscles: The muscles that make up the heart, including their structure and function.
Heart valves: The four valves in the heart, including their structure and function.
Blood pressure: The force exerted by circulating blood against the walls of the blood vessels, affected by factors such as fluid volume and resistance.
Blood disorders: Abnormalities in the blood that can affect cardiovascular health, such as anemia, high blood pressure, and thrombosis.
Coronary circulation: The circulation of blood to the heart, including the coronary arteries and veins.
Conduction system: The electrical system that regulates the heartbeat, including the sinoatrial node, atrioventricular node, and Purkinje fibers.
Respiratory function: The relationship between cardiovascular function and the respiratory system, including gas exchange and oxygen delivery.
Cardiovascular disease: Conditions that affect the cardiovascular system, including heart disease, stroke, and peripheral artery disease.
Drugs and treatments: Medications and procedures used to treat cardiovascular conditions, including anticoagulants, beta-blockers, and stents.
Exercise and fitness: The role of exercise in promoting cardiovascular health, including its impact on heart rate, blood pressure, and circulation.
Heart: The heart is the organ responsible for pumping blood throughout the body.
Blood vessels: Blood vessels are tubes that carry blood to and from the heart. There are three types of blood vessels: arteries, veins, and capillaries.
Arteries: Arteries are blood vessels that carry oxygen-rich blood away from the heart to the rest of the body.
Veins: Veins are blood vessels that carry deoxygenated blood back to the heart.
Capillaries: Capillaries are small blood vessels that connect arteries and veins and allow for the exchange of oxygen, nutrients, and waste products between the blood and the body's tissues.
Blood: Blood is a fluid that carries oxygen, nutrients, and waste products throughout the body. It is made up of red blood cells, white blood cells, platelets, and plasma.
- "It includes the cardiovascular system, or vascular system, that consists of the heart and blood vessels."
- "The circulatory system has two divisions, a systemic circulation or circuit, and a pulmonary circulation or circuit."
- "The circulatory system is closed in vertebrates, which means that the blood never leaves the network of blood vessels."
- "Blood is a fluid consisting of plasma, red blood cells, white blood cells, and platelets."
- "It is circulated around the body carrying oxygen and nutrients to the tissues and collecting and disposing of waste materials."
- "In vertebrates, the lymphatic system is complementary to the circulatory system."
- "The lymphatic system carries excess plasma... back to blood circulation as lymph."
- "The lymphatic system also works with the immune system."
- "unlike the closed (blood) circulatory system, the lymphatic system is an open system."
- "The circulation of lymph takes much longer than that of blood."
- "Cardiologists are medical professionals which specialize in the heart."
- "Cardiothoracic surgeons specialize in operating on the heart and its surrounding areas."
- "Vascular surgeons focus on disorders of the blood vessels, and lymphatic vessels."
- "The network of blood vessels are the great vessels of the heart including large elastic arteries, and large veins."
- "capillaries that join with venules (small veins), and other veins."
- "Diploblasts such as sponges, and comb jellies lack a circulatory system."
- "Circulated nutrients include proteins and minerals."
- "help maintain homeostasis by stabilizing temperature and natural pH."
- "The lymphatic system is a subsystem that is essential for the functioning of the blood circulatory system; without it the blood would become depleted of fluid."
