Title: Circulatory System


1
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
10
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
