Foundation Standard 1: Circulatory Systen
• The heart is best described as a muscular pump.• It is about the size of an apple.• The artery is the most muscular and elastic type
of blood vessel.• Oxygen and carbon dioxide exchange takes place
in the capillaries.• Systole, when the heart is beating, follows
diastole, when the heart is resting.• When and electrical impulse leaves the bundle of
His, heart muscle cells specialized for electrical conduction, they go to the Purkinje fibers.
• Neutrophils and lymphocytes are examples of leukocytes (white blood cells).
Heart and Blood Vessels
Blood Flow
• If a person becomes dehydrated, there would be less plasma in their blood.
• If a person does not have enough erythrocytes, he/she would have difficulty carrying oxygen.
• Anemia can be caused by a lack of hemoglobin.
• If there was a hole in the septum, blood would move between the right and left sides of the heart.
• A myocardial infarction is life threatening because a damaged heart muscle cannot pump blood effectively.
• If someone is diagnosed with aneurysm, there is a weakness in the wall of their artery.
