Final Exam Anatomy I Flashcards
List the functions and basic components of the lymphatic system.
Components:
Lymph- fluid
Lymphatic vessels
Lymphatic tissue
Lymphatic organs
Functions:
Recover fluid lost from blood capillaries, guard against pathogens (immunity), and absorb lipids from small intestine.
Explain how lymph is formed.
Clear, colorless fluid
Similar to blood plasma; low in lymphatic vessels, supplies lymphocytes to blood stream, lymph in intestine is chyle.
Explain what makes lymph flow through the lymphatic vessels.
Name the major types of cells in the lymphatic system and state their functions.
Describe the types of lymphatic tissue.
Describe the anatomy and lymphatic- immune function of the red bone marrow, thymus, lymph nodes, tonsils, and spleen.
Define immune system and explain its relationship to the lymphatic system.
Identify the body’s three line of defense against disease agents.
Distinguish between innate and adaptive immunity.
Describe the embryonic origins of the lymphoid organs.
Describe some common disorders of the lymphatic and immune systems.
a. Autoimmune diseases- immune attack of own tissues
i. Examples: insulin-dependent
diabetes, rheumatoid arthritis.
b. Allergies- exaggerated immune responses.
c. Immunodeficiency diseases- failure of immune responses.
Describe changes in the lymphatic system that occur with old age.
a. Quality of red marrow, lymphatic tissue, and thymic hormones decline.
i. Fewer helper T cells, slower
responses to antigens,
increased incidence of cancer.
ii. Poorer discrimination of
antigens result in increase in
autoimmune disease
incidence.
State the functions of the respiratory system.
Name the principal organs of this system.
Distinguish between the conducting and respiratory divisions.
Distinguish between the upper and lower respiratory tracts.
Trace the flow of air from the nose through the larynx.
Describe the action of the vocal cords in speech.
Trace the flow of air from the trachea to the pulmonary alveoli.
Relate the microscopic anatomy of the pulmonary alveoli to their role in gas exchange.
