Anatomy & Physiology Fall Exam

Front

What is adipose tissue primarily composed of?

Back

Adipose tissue is predominantly composed of fat cells.

Front

Which of the following does NOT belong: blood, suspension, solution, Italian dressing?

Back

Solution does NOT belong as it is a homogeneous mixture, while the others can be heterogeneous.

Front

What cavities provide proper locations for the heart?

Back

The ventral, thoracic, and pericardial cavities all provide proper locations for the heart.

Front

What characteristic do epithelial tissues exhibit?

Back

Epithelial tissues always exhibit polarity, meaning they have a free surface.

Front

Why is water considered a great solvent?

Back

Water is a great solvent because it is polar, allowing it to dissolve many substances.

Front

Define polarity in the context of epithelial tissue.

Back

Polarity refers to the structural and functional differences between the apical (free) surface and the basal surface of epithelial cells.

Front

What is the function of adipose tissue in the body?

Back

Adipose tissue stores energy, insulates the body, and provides cushioning for organs.

Front

What distinguishes a suspension from a solution?

Back

A suspension contains larger particles that can settle out, while a solution is a homogeneous mixture where particles are evenly distributed.

Front

What is the significance of the pericardial cavity?

Back

The pericardial cavity surrounds the heart and provides a protective layer, allowing for movement and reducing friction.

Front

How does the polarity of water affect its solvent properties?

Back

The polarity of water allows it to interact with and dissolve ionic and polar substances, making it an effective solvent.
