Final answer:
The question involves choosing root terms for the lymphatic, blood, and respiratory systems and noting their significance in maintaining bodily homeostasis and their role in defense against pathogens.
Step-by-step explanation:
The student is asked to choose five root terms each from the lymphatic, blood, and respiratory systems. For the lymphatic system, relevant terms could include: lymph, thymus, spleen, leuko- (as in leukocytes), and immuno- (as in immunity).
For the blood system, possible terms are: erythro- (as in erythrocytes), hemato- (as in hematology), plasma, thrombo- (as in thrombocytes or platelets), and cyto- (as in the cells). Lastly, for the respiratory system, appropriate terms might be: pulmo- (as in pulmonary), broncho- (as in bronchus), alveolo- (as in alveoli), naso- (as in nasal), and tracheo- (as in trachea).
These systems are critical in maintaining homeostasis within the body. The circulatory and lymphatic systems lack normal microbiota because they are typically sterile environments, with infections occurring when pathogens breach the body's defenses. The chapter outlines discuss how microorganisms overcome these defenses and the consequent signs and symptoms of disease associated with infections of the circulatory and lymphatic systems.
