Circulatory System
2
Function TRANSPORT

• Gases (respiration)
• Nutrients (digestion)
• Waste (excretion)
• Hormones (endocrine)
• White blood cells (immune)

3
Major Structures

• Heart
• Blood vessels
• Blood

4
Heart
Ascending Aorta/ Aortic Arch

• Muscle (organ) that pumps blood
• The heart does work on blood by moving it from
  one place to another in the body.

Superior Vena Cava
Pulmonary Veins
Pulmonary artery
Inferior Vena Cava
5
Blood Vessels

• Connect heart to bodys major organs
• Delivers essential materials dissolved in blood
  to organs

6
Types of Blood Vessels

• Arteriesmove
• blood away from
• the heart

7
Types of Blood Vessels

• Arteriesmove
• blood away from
• the heart
• Veinsmove blood
• toward the heart

8
Types of Blood Vessels

• Arteriesmove blood away from the heart
• Veinsmove blood
• toward the heart
• Capillaries
• microscopic blood
• vessels that connect
• arteries veins
• Capillaries exchange food, oxygen and wastes.

9
Cardiovascular System

• Cardio heart Vascular vessels
• Made up of heart, vessels, and blood
• Closed systemblood stays inside the vessels
• Blood only flows one-way

Pulmonary Circulation Blood flow between the
Heart and Lungs
When Blood moves into the heart tissue, it is
called Coronary Circulation
Arterial Circulation Moves blood to all the
organs and tissues

Functions of the Blood

1. Carries oxygen from lungs to all body cells
   removes carbon dioxide from the cells
2. Carries waste products of cell activity to
   kidneys to be removed from the body
3. Transports nutrients from digestive system to
   body cells
4. Materials in blood
5. help fight infection
6. and heal wounds
