Cardiac muscle fibers are branched.
...
This is a thin single layer of cells that allows for diffusion.
...
The type of muscle tissue surrounding internal organs, other than the heart, is ___.
smooth muscle
Blood is specialized for the transport of substances such as nutrients, wastes, and gases.
...
Loose connective tissue is a packing material that serves, for example, to hold organs in place.
...
Smooth muscle is responsible for the involuntary contractions of the digestive tract, arteries, and bladder.
...
Stratified epithelium consists of multiple layers; this thickness provides a protective barrier.
...
The ends of long bones, such as the femur, have a cartilage cap.
...
How does connective tissue differ from the other three major tissue types?
Connective tissue often consists of relatively few cells embedded in an extracellular matrix.
Which of these describes loose connective tissue?
It is a loose weave of fibers that functions as a packing material.
_____ muscle is attached to bones.
Skeletal
Which of the following is a correct statement about an organism and its environment?
The interstitial fluid is the exchange medium between body cells and the circulatory system in vertebrate animals.
Cartilage is found _____.
at the ends of bones such as the femur
Most of the exchange surfaces of multicellular animals are lined with ___.
epithelial tissue
The nourishment, insulation, and support for neurons is the result of activity by the ___.
glial cells
All types of muscle tissue have ___.
interactions between actin and myosin
The four major categories of tissues are _____.
nervous, epithelial, connective, and muscle
Fibroblasts secrete ___.
proteins for connective fibers
Food moves along the digestive tract as the result of contractions by ___.
smooth muscle
What type of muscle is responsible for contractions of the digestive tract and arteries?
smooth muscle
What type of epithelium would you expect to find covering a surface subject to physical forces?
stratified epithelium
All skeletal muscle fibers are ___.
striated and under voluntary control.
Muscles are joined to bones by ___.
tendons
Penguins, seals, and tuna have body forms that permit rapid swimming, because ___.
the shape is a convergent evolutionary solution to the need to reduce drag while swimming
As body size increases in animals, ___.
there is a decrease in the surface-to-volume ratio
Nervous tissue functions _____.
to sense stimuli
The interstitial fluid takes up nutrients and oxygen from the blood plasma for transfer to active cells, and the active cells are the source of wastes and carbon dioxide for transfer to the blood plasma.
...
The simple cuboidal cells of kidney tubules allow for both secretion and absorption.
...
This describes many connective tissues, such as loose connective tissue.

connective tissue
A neuron consists of _____.
dendrites, a cell body, and axons
Blood is best classified as connective tissue because ___.
its cells are separated from each other by an extracellular matrix.
Connective tissues typically have ___.
relatively few cells and a large amount of extracellular matrix
