- "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."
The study of the structure and function of the heart and blood vessels.
Anatomy of the Heart: This topic covers the structure and location of the heart, including the four chambers, valves, and blood vessels.
Cardiac Cycle: This topic covers the sequence of events that occur during one heart beat, including the phases of ventricular systole and diastole.
Electrical Conduction of the Heart: This topic covers the electrical impulses that regulate the heartbeat, including the SA node, AV node, bundle of His, and Purkinje fibers.
Blood Vessels: This topic covers the different types of blood vessels, including arteries, veins, and capillaries, as well as their structure and functions.
Blood Pressure: This topic covers the measurement of blood pressure, including the systolic and diastolic readings, and the factors that affect blood pressure, such as vasoconstriction and vasodilation.
Cardiovascular Diseases: This topic covers the different types of cardiovascular diseases, including atherosclerosis, hypertension, angina, heart attack, and stroke, as well as their causes and treatments.
Cardiopulmonary System: This topic covers the relationship between the cardiovascular system and the respiratory system, including the exchange of gases and the regulation of oxygen and carbon dioxide levels in the blood.
Blood Composition: This topic covers the components of blood, including red blood cells, white blood cells, platelets, and plasma, as well as their functions and roles in the cardiovascular system.
Lymphatic System: This topic covers the lymphatic vessels and lymph nodes, and their role in the immune system and the cardiovascular system.
- "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."
