Chapter 10: Cardiovascular, Immune, and Lymphatic Systems and Blood
Functions & Organs InvolvedCardiovascular System – pumps and transports blood
throughout the bodyConsists of heart and closed network of blood vessels
composed of arteries, veins, and capillariesHeart pumps blood containing O2 and nutrients to body
tissues (arteries)There is an exchange of gases, nutrients, and waste
between blood and body (capillaries)The blood carrying CO2 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.’dLymphatic System – 3 functions
1. Return excessive tissue fluid to the blood2. Absorb fats and fat-soluble vitamins from small
intestine and transport them to the blood3. 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 body2. 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

mouth to anusPrepares ingested food for use by the body cells
through physical and chemical digestionEliminates the solid waste products from bodyOrgans involved include mouth, throat, esophagus,
stomach, small intestine, large intestine, anus
