Chapter 33 The Animal Body: Basic Form and Function

An example of a connective tissue is the

blood

Which of the following tissues is striated, contains cells with one nucleus each, and is NOT under voluntary control?

cardiac muscle

Most of the exchange surfaces of multicellular animals are lined with

epithelial tissue.

An exchange surface in direct contact with the external environment is found in the

lungs

Tissues are composed of cells, and tissues functioning together make up

organs

The specialized function shared by the cells that line the lungs and those that line the lumen of the gut is that both types of cells

provide abundant exchange surface.

Of the following choices, the epithelium with the shortest diffusion distance is

simple squamous epithelium.

Breathing is accomplished via the rhythmic contraction and relaxation of

skeletal muscle.

Food moves along the digestive tract as the result of contractions by

smooth muscle

The flat shaped cells found in the epidermis of the skin are :

squamous

Cardiac muscle cells are both

striated and interconnected by intercalated disks

Muscles are joined to bones by

tendons

Positive feedback differs from negative feedback in that

the positive feedback's effector responses are in the same direction as the initiating stimulus rather than

As body size increases in animals,

there is a decrease in the surface-to-volume ratio.

The specialized structures of complex animals have evolved because

they permit adjustments to a wide range of environmental changes.
