Circulatory System

• A) Anatomy
• Inside the heart
• 4 cavities
• Two upper cavities are called ATRIUMS
• Two lower cavities are called VENTRICLES
• Outside the heart
• Major Veins (brings blood to the heart)
• Inferior and Superior Vena Cava
• Pulmonary veins
• Major Arteries (brings blood away from the heart)
• Aorta
• Pulmonary Artery

Circulatory System

• B) Circulations
• Within the Heart
• Blood always circulates from the Atrium to the
  Ventricle
• Outside of the Heart
• Systemic Circulation
• Heart to the cells and cells to the heart
• Pulmonary Circulation
• Heart to the lungs and lungs to the heart

5
Circulatory System

• Systemic circulation
• Goal
• Brings blood from the heart to the cells and
  from the cells to the heart
• Starts from
• Left Ventricle, Aorta, arteries, arterioles,
  capillaries, venules, veins, Vena Cava (inferior
  or superior) Right Atrium.

6
Circulatory System

• Pulmonary circulation
• Goal
• Brings blood from the heart to the lungs and
  from the lungs to the heart
• Starts from
• Right Ventricle, Pulmonary Artery, lungs,
  Pulmonary Veins, Left Atrium.

Circulatory System

• Blood Components
• Red blood cells
• Transport Oxygen
• White Blood Cells
• Protects the system
• Platelets
• Helps coagulate the blood
• Plasma
• Liquid component of the blood

8
Circulatory System

• Blood Typing
• Red blood cells have different proteins
• A
• B
• Rh
• The combination of these allow us to determine
  our blood types

Circulatory System

• Blood Transfusions
• You cannot give a protein to someone who does not
  already have it.
