- The cardiac cycle refers to the sequence of mechanical and electrical events that repeats with every heartbeat. It includes the phase of relaxation diastole and the phase of contraction systole. Because the human heart is a four chambered organ, there are atrial systole, atrial diastole, ventricular systole and ventricular diastole.

Circulatory system The circulatory system, also called the cardiovascular system or the vascular system, is an organ system that permits blood to circulate and transport nutrients (such as amino acids and electrolytes), oxygen, carbon dioxide, hormones, and blood cells to and from the cells in the body to provide nourishment and help in fighting diseases, stabilize ...

- The cardiovascular system consists of the heart, blood vessels, and the approximately 5 liters of blood that the blood vessels transport. Responsible for transporting oxygen, nutrients, hormones, and cellular waste products throughout the body, the cardiovascular system is powered by the body’s hardest-working organ — the heart, which is only about the size of a closed fist. Even at rest, the average heart easily pumps over 5 liters of blood throughout the body every minute....

Cardiovascular Disease High blood pressure, heart disease, and stroke are the most common forms. Cardiovascular disease (CVD) refers to diseases that affect the heart or the blood vessel system within a person's entire body. It is not one single disease or condition. Rather, it is a group of over 60 different disorders.

Cardiovascular System Anatomy Functions of the Cardiovascular System. The cardiovascular system has three major functions: transportation of materials, protection from pathogens, and regulation of the body’s homeostasis. Transportation: The cardiovascular system transports blood to almost all of the body’s tissues. The blood delivers essential nutrients and oxygen and removes wastes and carbon dioxide to be processed or removed from the body. Hormones are transported throughout the body via the blood’s liquid plasma.

- The cardiovascular system, is a closed-loop system, such that blood is pumped out of the heart through one set of vessels (arteries) and then returns to the heart in another (veins).

Anatomy Lesson 11 Circulatory System The cardiovascular, or circulatory, system in humans is composed of the heart and the blood. vessels--arteries, veins, and capillaries. Its purpose is to provide nutrients and oxygen to the tissues and to remove wastes from them.right red, oxygen-rich blood from the pulmonary circulation flows from the left atrium into the left ventricle. With each beat of the heart, blood is forced through the large artery of the heart, called the aorta, and throughout the body by a network of arteries.

Introduction to the Cardiovascular System Introduction to the Cardiovascular System. The cardiovascular system is sometimes called the blood-vascular, or simply the circulatory, system. It consists of the heart, which is a muscular pumping device, and a closed system of vessels called arteries, veins, and capillaries.

Cardiovascular disease Cardiovascular disease (CVD) is a class of diseases that involve the heart or blood vessels.Cardiovascular disease includes coronary artery diseases (CAD) such as angina and myocardial infarction (commonly known as a heart attack). Coronary artery disease (also known as coronary heart disease and ischemic heart disease). 2  Peripheral arterial disease – disease of blood vessels that supply blood to the arms and legs. 3  Cerebrovascular disease – disease of blood vessels that supply blood to the brain (includes stroke).

Major Functions of the Cardiovascular System Transportation of nutrients, gases and waste products. The cardiovascular system acts as an internal road network, linking all parts of the body via a system of highways (arteries and veins), main roads (arterioles and venules) and streets, avenues and lanes (capillaries).

Cardiology Cardiology (from Greek καρδίᾱ kardiā, heart and -λογία -logia, study) is a branch of medicine dealing with disorders of the heart as well as parts of the circulatory system. The field includes medical diagnosis and treatment of congenital heart defects, coronary artery disease, heart failure, valvular heart disease and electrophysiology.

Functions of the Cardiovascular System The blood carries oxygen and nutrients to every cell of the body. The cardiovascular system is actually comprised of two systems: The pulmonary circulation, in which the heart pumps the blood to your lungs and back again, and the circulatory system, in which the heart pumps the oxygen-rich blood to the rest of the body.he function of the cardiovascular system include keeping our bodies at a constant temperature, maintaining fluid balance throughout the tissues, protecting the body from blood loss and infection, and helping move waste products out of the body. Here is more detail about what the cardiovascular system does:
