Body by Design Chapters 9-12 Flashcards
___ must be collected for removal from the body.
Carbon dioxide and other byproducts of cellular metabolism
The nervous system has the ___ number of connections and least degree of order, organization, and integration in the body.
highest
The respiratory system is responsible for supplying ___ to the blood and expelling waste gases.
oxygen
The multiple parts of ___ must work fully in place and together in precision, or the function is impaired.
the eye and the ear
The ___ serves as a telegraph cable that allows signals to be sent from the brain to the structures of the body and received from them in return.

Briefly describe how the diaphragm, intercostal and abdominal muscles, ribs, and pleural membranes aid the respiratory system.
The diaphragm and the intercostal and abdominal muscles are responsible for contracting and expanding the thoracic cavity to effect respiration. The ribs serve as a structural support for the whole thoracic arrangement. The pleural membranes help provide lubrication for the respiratory organs so that they are not chafed during respiration.
List the 3 types of blood vessels and briefly describe their functions.
a. Arteries are thick-walled, muscular blood vessels that carry blood away from the heart to the organs and tissues of the body.
b. Capillaries are the functional units of the circulatory system and bring blood within reach of every cell.
c. Veins are vessels that carry blood from the capillaries of the organs and tissues toward the heart.
In order for the body to stay alive, each of its cells must receive a continuous supply of ___.
nutrients and oxygen
___ is the primary waste gas expelled by the lungs.
Carbon dioxide
Some evolutionists argue that the cephalopod eye of the octopus and squid are superior to the human eye. Why are these assertions wrong?
Cephalopod eyes are extremely nearsighted, somewhat colorblind, and unlikely to form sharp images as our eyes can. The cephalopod has eyes designed for life in the deep oceans. The human eye, like the eyes of other vertebrates, has vision that is superior to cephalopods. Evolutionists have ignored these finer details of the structure and function in the human eye when they say the human eye is suboptimal to the eye of a cephalopod.
It takes a ___ to build immunity to the majority of cold viruses in one’s environment.
lifetime
