Circulatory syste mblood lymph

  1. 1. CIRCULATORY SYSTEM
  2. 2. • Materials are moved throughout your body by the cardiovascular system – This system includes your heart, blood vessels, and blood
  3. 3. • The heart is the organ that continuously circulates blood throughout the body.
  4. 4. • Blood vessels carry blood to every part of the body • Blood moves oxygen and nutrients to cells, and carries wastes away from the cells
  5. 5. • The heart is made of cardiac muscle tissue • The heart has four compartments called chambers • The upper chambers are the right and left atriums • The lower chambers are called ventricles
  6. 6. • Blood flows in only one direction, from an atrium to a ventricle, then from a ventricle to a blood vessel
  7. 7. • There are three types of circulation: – Coronary circulation – Pulmonary circulation – Systemic circulation • The beating of your heart controls blood flow for all of them
  8. 8. • Coronary circulation is the flow of blood to and from tissues of the heart (takes place within the heart) • Pulmonary circulation is the flow of blood through the heart to the lungs and back to the heart • In systemic circulation, oxygen-rich blood moves to all organs and body tissues (except the heart and lungs) – Systemic circulation is the largest of the three sections of the circulatory system
  9. 9. • Systemic circulation relies on blood vessels called arteries and veins to carry blood to organs • Arteries carry blood away from the heart – Each ventricle of the heart is connected to an artery – The right ventricle is connected to the pulmonary artery – The left ventricle is attached to the aorta, the largest artery in the body
  10. 10. • Veins carry blood back to the heart - Veins have one-way valves that keep blood moving toward the heart • Arteries and veins are connected by microscopic blood vessels called capillaries
  11. 11. • Blood pressure is what we call the force of blood on the walls of blood vessels
  12. 12. • Blood pressure is expressed by two numbers, called the systolic pressure and the diastolic pressure “normal” blood pressure is 120 over 80
  13. 13. • Cardiovascular disease is the leading cause of death in the U.S. – Diseases that affect the cardiovascular system affect the health of the whole body
  14. 14. • Atherosclerosis is a condition in which fatty deposits build up on artery walls
  15. 15. • Hypertension is high blood pressure. This places extra strain on the heart • Heart failure results when the heart cannot pump blood efficiently
  16. 16. • Most cardiovascular disease can be prevented by having a healthy lifestyle, including healthy eating habits, exercise, and getting enough sleep
