• Arteries
• Veins
• Small blood vessels are capillary walls
• Pathway for white blood cells, to fight infections anywhere in body.

Types of Circulatory Systems

Vascular System
Cardiovascular System

• Simple
  • Gastrovascular System
  • Ex:
    • Jellyfish
    • Flatworms
• Complex
  • Open Circulatory System
  • Closed Circulatory System
  • Closed is better the larger an organism is.
    • They need to more efficiently transport their nutrients and oxygen and more efficiently remove waste.
  • Vertebrates
  • Mammalian Circulatory System
    • Blood vessel cycles

Disorders

  • Lack of iron
  • Low Red Blood Cells

• Leukemia

  • White Blood Cells are in abundance

• Hemophilia

  • Bleeders disease

• Heart Murmur

  • Cardiac Arrhythmias

• Heart attack

  • Mycardial Infarction
  • Blood Vessels become blocked
