What is the purpose of the serous fluid that is located between visceral and parietal serosa?
It allows organs to slide with little friction against each other and against the cavity walls.
Which of the following statements are accurate concerning light microscopy?
It is limited because it cannot produce sharp images of structures within cells

What is the major difference in scanning electron microscopy (SEM) when compared to light microscopy (LM) or transmission electron microscopy (TEM)?
SEM uses whole, unsectioned surfaces that are covered in carbon and gold dust.
Which of the following best represents an example at the organ level? -Hydrochloric acid - Digestive enzymes -Enterocytes (cells that line the small intestine) -Stomach -Smooth muscle in the large intestine
Stomach

Thigh
The body region containing the axillary, sternal, and mammary regions is the _____.
Thorax
The proximal convoluted tubule is a structure within the kidney nephron that plays a significant role in the reabsorption of important products that have been filtered from the blood. One of the key features of this structure is its lining. The cells that line the tubule are responsible for the transport of substances across the membrane. These cells and their collective efforts would be an example of which of the following levels?
Tissue Level
Segmented Outer tube gives rise to:
Vertebrae, muscle segments

distal: superior
What is the advantage of functional magnetic resonance imaging (fMRI) over positron emission tomography (PET)?
fMRI pinpoints smaller brain areas, does not use radioactive tracers, and works faster.
