The circulatory system is responsible for delivering nutrients and oxygen, fighting infections, and regulating body temperature. It consists of the heart, which has two atriums and two ventricles, and blood vessels including arteries, capillaries, and veins, organized into pulmonary and systemic loops. Key components include epithelial tissue covering the heart, red blood cells for oxygen transport, and white blood cells that combat infections.

- High Blood Pressure
- Heart Attack (occurs when
an artery is blocked from
delivering oxygen to the
heart)
- Stroke (occurs when blood
clots get stuck in a blood

4. Structures
- Heart (2 atriums- receive
blood, 2 ventricles - pump
blood out)
- Blood Vessels (arteries,
capillaries, and veins)
- 2 Circulatory Loops

5. how does it work?
- muscle around the heart
(myocardium) helps pump
blood through circulatory
system
- as blood flows through the
system, it travels through
three vessels (arteries,
capillaries, and veins)
- arteries carry blood from the
