  3. Anatomy and Physiology Functions of the Cardiovascular System • To transport blood throughout the body • To deliver oxygen and nutrients to body cells through arteries and capillaries • To remove waste products from body cells through capillaries and veins • To pump blood through the heart with the aid of electrical conduction

  4. Anatomy and Physiology Structures of the Cardiovascular System • Heart wall has three tissue layers. • Heart has four chambers and valves. • Heart muscle and tissue are specialized. • Arteries carry blood away from the heart. • Capillaries allow for exchange of gasses. • Veins return blood back to the heart.

  5. Anatomy and Physiology (cont.) The cardiovascular system

  6. Anatomy and Physiology Functions of the Lymphatic System • To return lymph from body tissues to the blood • To protect the body by filtering microorganisms and foreign particles from the lymph • To maintain the body’s internal fluid level • To absorb fats from the small intestines

  7. Anatomy and Physiology Structures of the Lymphatic System • Lymph is clear tissue fluid consisting of white blood cells and a few red blood cells. • Lymph nodes filter the lymph. • Lymph nodes are primarily concentrated in the neck, chest, armpits, and groin. • Lymph vessels transport the lymph from the body tissues to the venous system. • Lymph valves facilitate one-way transport of lymph.
