Which of the following statements correctly describes the function of the corresponding
ii ii
physiologic structure?
ii ii ii ii ii ii ii ii ii ii ii ii ii ii
A. The trachea connects the throat and the stomach, encouraging food to follow this path
ii ii
through contractions.
ii ii ii ii ii ii ii ii ii ii ii ii ii ii ii
B. The esophagus is the cylindrical portion of the respiratory tract that joins the larynx with
ii ii
the lungs.ii ii ii ii ii ii ii ii ii ii ii ii ii ii ii
C. the diaphragm is a muscle that controls the height of the thoracic cavity, decreasing the
ii ii ii ii ii ii ii ii ii ii ii
height on contraction, and increasing the height on relaxation causing expiration.
ii ii ii ii ii ii ii ii ii ii ii ii
D. The epiglottis covers the trachea during swallowing, preventing food from entering the
ii
airway. ii ii ii ii ii ii ii ii ii ii ii ii ii
D. The epiglottis covers the trachea during swelling, thus preventing food from entering the
ii ii
airway.
ii ii ii ii ii ii ii ii ii ii ii ii ii ii
- The trachea (windpipe) is cylindrical portion of the reparatory tract that joins the larynx
ii ii ii ii
with the lungs.
ii ii ii ii ii ii ii ii ii ii ii ii ii
- The esophagus connects the throat and the stomach. When a person swallows, the
ii ii ii ii ii ii ii ii ii ii ii ii ii
esophagus contracts to force the food down into the stomach. The esophagus secretes
ii ii ii ii
mucus for lubrication.
ii ii ii ii ii ii ii ii ii ii ii ii ii ii ii
- The diaphragm is a muscle that controls the height of the thoracic cavity, increasing the
ii ii ii ii ii ii ii ii ii ii ii
height on contraction (inspiration), and decreasing the height on relaxation (expiration).
ii ii ii ii ii ii ii ii ii ii ii ii ii ii ii ii
Which of the following is an example of the location and function of cartilage int he body?
ii ii ii ii ii ii ii ii ii ii ii ii ii
A. The dense connective tissue that comprises the better part of the structural skeleton.
ii ii ii ii ii ii ii ii ii ii ii ii ii ii ii
B. The supportive pads that provide cushion at joints, such as between the vertebrae of the
ii ii
spinal cord.
ii ii ii ii ii ii ii ii ii ii ii ii
C. The connective structure made of fibrous collagen that connects muscles and bones,
ii ii ii ii ii ii ii ii ii ii
such as the connection of the patella to the quadricep.
ii ii ii ii ii ii ii ii ii ii ii ii ii ii
D. The layer beneath the skin and on the outside of internal organs that provides
ii ii ii
cushioning and protection.
ii ii ii ii ii ii ii ii ii ii ii ii
B. The pads that support the vertebrae are made up of cartilage.
ii ii ii ii ii ii ii ii ii ii ii ii ii
- Cartilage, a strong form of connective tissue, cushions ad supports the joints. Cartilage
ii ii ii ii ii ii ii ii ii
also makes up the larynx and the outer ear.
ii ii ii ii ii ii ii ii ii ii ii ii ii ii ii ii
- Bone is a form of connective tissue that comprises the better part of the skeleton. It
ii ii ii ii ii ii ii
includes both organic and inorganic substances.
ii ii ii ii ii ii ii ii ii ii ii ii ii
- Tendons connect the muscles to other structures of the body, typically bones. Tendons
ii ii ii ii ii ii ii ii ii ii ii
can increase and decrease in length as the bones move.
ii ii ii ii ii ii ii ii ii ii ii ii ii ii ii ii ii ii
- Fat is a combination of lipids; in humans, fat forms a layer beneath the skin and on the
ii ii ii ii ii
outside of the internal organs.

Two criteria for classifying epithelial tissue are:
ii ii ii ii ii
A. Cell type and cell function
ii ii ii ii ii
B. Cell shape and cell type
, ii ii ii ii ii
C. Cell layers and cell shape
ii ii ii ii ii
D. Cell function and cell layers
ii ii ii ii ii ii ii ii ii ii ii ii
C. Cell layers and cell shape are the criteria for classifying epithelial tissue.
ii ii ii ii ii ii ii ii ii ii ii ii ii ii ii
- Cell layers refers to the amount of cells that separate the basement membrane from the
ii ii ii ii ii ii ii ii ii ii ii ii ii ii ii ii
surface, such as a simple single layer, a stratified layer (2 or more), or a pseudostratfied
ii ii
layer.
ii ii ii ii ii ii ii ii ii ii ii ii ii ii ii ii
- Cell shapes refer to the shape of the outer cells and can be squamous, columnar or
ii
cuboidal. ii ii ii ii ii
Where is the parathyroid gland located?
ii ii ii ii ii ii ii ii ii ii ii ii

ii ii ii ii ii ii ii ii ii ii ii ii
B. On the pyramidal lobe of the thyroid gland, on the posterior aspect.
ii ii ii ii ii ii ii ii ii
C. On the lateral thyroid gland, on the anterior aspect.
ii ii ii ii ii ii ii ii ii ii ii ii ii
D. On the left lateral lobe of the thyroid gland, on the anterior aspect.
ii ii ii ii ii ii ii ii ii ii ii ii ii ii ii ii ii
A. The parathyroid gland is located on the lateral lobes of the thyroid gland in the neck, on
ii ii ii ii
the posterior aspect.
ii ii ii ii ii ii ii ii
- It is part of the endocrine system.
ii ii ii ii ii ii ii ii ii ii ii ii ii ii
- When the supply of calcium in blood diminishes to unhealthy levels, the parathyroid gland
ii ii ii ii ii ii ii ii ii ii ii ii ii ii
motivates the secretion of a hormone that encourages the bones to release calcium into
ii ii ii ii ii ii ii ii ii ii ii ii ii
the bloodstream. The parathyroid Gand also regulates the amount of phosphate in the
ii ii ii ii ii ii ii ii ii ii
blood by stimulating the excretion of phosphates in the urine.
