HeartHeart
Fist sized bag consisting of two pumps
One for pulmonary One for systemic
Blood VesselsBlood Vessels
90,000 Miles of blood vessels networked together to make up the circulatory system
Function of the Circulatory Function of the Circulatory SystemSystem
Maintain an internal environment
Nourish all of the cells of the body
HeartHeart
Special type of musclemyocardium
Pulmonary Heart SystemPulmonary Heart System
Left Side Receives oxygen rich
blood from the lungs Pumps oxygen rich
blood to the body Oxygen is passed to
body tissue and blood returns to the heart
Systemic System
Lungs
Right Lung
Left Lung
Systemic System of the HeartSystemic System of the Heart Right Side Receives oxygen
deficient blood into the hearts atrium
Right Atrium is known as the hearts pacemaker
Passes to the ventricle Heart pumps the blood to
the lungs Blood returns to the left
side of the heart
One-way ValvesOne-way Valves
Located at the exit of each chamberGuarantees that blood flows in one
directionPrevents what is known as backflow
Right AtriumRight Atrium
SA Node is the hearts pacemaker The Synarthrodial node controls the heart
rate
Blood Blood
Delivers oxygen, hormones, and nutrients to the cells and caries away waste product
Red blood cells contain hemoglobin rich in iron for oxygen to attach too
YouTube - Oxygen Transport Plasma is 92% water, it also contains salts,
proteins,red blood cells, white blood cells and plateletsYouTube - How the Body Works : Blood Clotting
Platelets the bloods clotting system
White Blood cellsWhite Blood cells
Protect against and fights infection
Form antibodies making you immune to the infection
Production increases when there is an infection in the body

Coronary vesselsCoronary vessels
Supply the myocardium with oxygen rich blood
These vessels branch directly from the aortahttp://www.youtube.com/watch?

Blood PressureBlood Pressure
The force of blood being applied to the main arteries measured in mm of mercury
Systolic (top Number) is arterial pressure at it’s highest point
Diastolic (bottom Number) measures the pressure on the arterial walls at its lowest or resting point
ArteriosclerosisArteriosclerosis
Plaque build up in the arteriesTreatment of angioplasty or stinthttp://www.youtube.com/watch?

Lymphatic and Respiratory Lymphatic and Respiratory SystemsSystems
Work to maintain fluid balance and fight infection
White blood cells make you immune to certain diseases: chicken pox, mumps, and measles.
Lymphatic SystemLymphatic System
Drains tissue fluid back into the bloodstream
Fights infectionsMovement of the muscles helps circulate
the lymph fluid (proteins, fats and white blood cells)
B CellsB Cells
Enlarge and multiply produce antibodies that destroy invading pathogens
T CellsT Cells
Attach to abnormal cells and emit toxins through a needle like projection to kill abnormal cells
Circulatory ConditionsCirculatory Conditions
Anemia- iron deficiency in a diet.
Congenital Heart Disease- hole in the chamber of the heart, malfunction of valves.
Heart Murmur- malfunctioning valve
Leukemia- prevents bone marrow from producing red blood platelets and white blood cells.
Hemophilia- blood is slow to clot.
Varicose Veins- swollen and enlarged veins.
