encapsulated.
anaplastic.
metastasized.
exfoliative.
question 3 (1 point)
listen
chronic pain is defined as:
showing an increase in blood pressure and heart rate.
starting as acute pain but continuing beyond the normal expected time for resolution.
a warning sign of a disturbance in physiology.

Explanation:

1. For Question 1: Leukemia is a cancer that originates in the bone marrow's blood-forming tissues, while sarcomas arise from connective tissues and lymphomas from lymphatic tissues.
2. For Question 2: Encapsulated tumors are surrounded by a fibrous capsule, preventing infiltration of nearby tissues; anaplastic refers to abnormal cell structure, metastasized means spread to other body parts, and exfoliative relates to shedding cells.
3. For Question 3: Chronic pain is characterized by persisting past the typical recovery period of acute pain, unlike acute pain which causes physiological changes like elevated blood pressure/heart rate and acts as a physiological warning.

Answer:

1. Leukemia.
2. Encapsulated.
3. Starting as acute pain but continuing beyond the normal expected time for resolution.
