Did You Get It & Chapter Review Questions Flashcards
Why would you have a hard time learning and understanding physiology if you did not also understand anatomy?
Anatomy and physiology are related. A given function can occur only if the corresponding structure allows it.
At which level of structural organization is the stomach? At which level is a glucose molecule?
The stomach exhibits the organ level of structural organization. Glucose is at the chemical level.
Which organ system includes the trachea, lungs, nasal cavity, and bronchi?
These organs are part of the respiratory system.
In addition to being able to metabolize, grow, digest food, and excrete wastes, what other functions must an organism perform if it is to survive?
Survival also depends on the ability to maintain one’s boundaries, to move, to respond to stimuli, and to reproduce.
Oxygen is a survival need. Why is it so important?
All the chemical reactions that occur in the body and release food energy require oxygen.
When we say that the body demonstrates homeostasis, do we mean that conditions in the body are unchanging? Explain your answer.
No. We mean that they vary within a narrow and regulated range.
When we begin to become dehydrated, we usually get thirsty, which causes us to drink liquids. Is the thirst sensation part of a negative or a positive feedback control system? Defend your choice.
Thirst is part of a negative feedback system. Thirst prods us to drink fluids (the response), which in turn causes the thirst sensation to decrease and end. Were it a positive feedback mechanism, we would become even more thirsty (the stimulus for drinking would increase).
Why is understanding the anatomical position important to an anatomy student?
Most descriptions of the body using anatomical terminology refer to body regions as if the body is in the anatomical position regardless of its actual position.
The axillary and the acromial areas are both in the general area of the shoulder. To what specific body area does each of these terms apply?
The axillary region is the armpit. The acromial region is the point of the shoulder.
Which kind of section would cut the brain into anterior and posterior parts?
A coronal or frontal section would cut the brain into anterior and posterior parts.
If you wanted to separate the thoracic cavity from the abdominal cavity of a cadaver, which type of section would you make?
To separate the thoracic and abdominal cavities, you would make a transverse section (XS).
Of the spinal cord, small intestine, uterus, and heart, which are in the dorsal body cavity?
Of these organs, only the spinal cord is in the dorsal body cavity.
