  1. Cardiovascular System Andrea Wolberg Marteka Fair Courtney Whittington

  2. What Is It? • The cardiovascular system is also known as the circulatory system • It is an organ system that moves substances to and from cells. • It can help stabilize body temperature

  3. Cardio Types • There are three types to the cardiovascular system • No circulatory system, open circulatory system, and closed circulatory system.

  4. Open Circulatory System • The open circulatory system is an arrangement of internal transport present in some invertebrates.

  5. Closed Circulatory System • The closed circulatory system is when all vertebrates, and cephalopods are closed, meaning that the blood never leaves the system of blood vessels consisting of arteries, capillaries and veins. • Poorly oxygenated blood collects in two major veins: the superior vena cava and the inferior vena cava

  6. No Circulatory System • An example of organisms without circulatory systems are flatworms (phylum Platyhelminthes). • Their body cavity has no lining or fluid. They have a muscular pharynx leading to a digestive system. • Oxygen can diffuse from water into the cells of the flatworm. As a result every cell is able to obtain nutrients, water and oxygen without the need of a transport system.

  7. Diseases in the System • Coronary artery disease (including heart attack) • Abnormal heart rhythms or arrythmias • Heart failure • Heart valve disease • Congenital heart disease • Heart muscle disease (cardiomyopathy) • Pericardial disease • Aorta disease and Marfan syndrome • Vascular disease (blood vessel disease

  8. How Activity Benefits the System • Exercise pumps more blood through your veins. • This increases the size of your arteries, prevents fat from clogging your arteries and helps prevent blood clots. • A strong heart does not have to work so hard so you are less likely to have a heart attack. Regular exercise also increases your HDL (good) cholesterol and helps lower your total cholesterol. • Exercise also helps lower your blood pressure.

  9. History • The valves of the heart were discovered by a physician around the 4th century BC. • In 1242 the Arab scholar Ibn Nafis became the first person to accurately describe the process of blood circulation in the human body. • In 1552, Michael Servetus described the same, and Realdo Colombo proved the concept, but it remained largely unknown in Europe. • William Harvey performed a sequence of experiments and announced in 1628 the discovery of the human circulatory system.

  10. Cardiovascular Measurement Techniques • Electrocardiogram • Sphygmomanometer • Pulse meter • Stethoscope • Pulse
