Begins on page 392 Chapter 10: Cardiovascular, Immune, and Lymphatic Systems and Blood

Functions & Organs Involved Cardiovascular System – pumps and transports blood throughout the body  Consists of heart and closed network of blood vessels composed of arteries, veins, and capillaries  Heart pumps blood containing O 2 and nutrients to body tissues (arteries)  There is an exchange of gases, nutrients, and waste between blood and body (capillaries)  The blood carrying CO 2 and waste is carried from tissues through veins to organs of excretion

The Heart

Functions Cont.’d Blood – maintains internal balance in the body; includes transportation, protection, and regulation 8% of body weight

Functions Cont.’d Lymphatic System – 3 functions 1. Return excessive tissue fluid to the blood 2. Absorb fats and fat-soluble vitamins from small intestine and transport them to the blood 3. Provide defence against infection Functions through a network of vessels, ducts, nodes, and organs Structures include lymph, lymphatic vessels and nodes, spleen, and thymus gland

Functions Cont.’d Immune System – protects body against pathogens, foreign agents that cause allergic rxns or toxins, and abnormal body cells Doesn’t have its own organs or structures It’s function depends no organs and structures of other systems Three lines of defense: 1. Prevention of foreign substances from entering in the body 2. Includes inflammation and fever plus phagocytosis (process in which some WBCs destroy invading microorganisms); also activated are protective proteins and natural killer cells 3. Specific immunity – provides protection against specific pathogens (such as polio) by forming specific antibodies
