In terms of hierarchy of organization, organs fall between _____ and _____.
tissues ... organ systems.
Tissues are composed of _____.
similar cells
Anatomy is to physiology as ___________.
a book is to reading
__________ are the fundamental units of life.
cells
What are the four major categories of tissues?
nervous, epithelial, connective, and muscle. These are the four major categories of
tissues. Nervous tissue is involved with communication. Epithelial tissue covers the
body and lines organs. Connective tissue binds and supports. Muscle tissue is involved
in movement.
What type of epithelium would you expect to find covering a surface subject to
physical forces?
Stratified epithelium consists of multiple layers; this thickness provides a protective
barrier.
What type of epithelial tissue, found in the intestines, absorbs nutrients?
Simple columnar epithelium, such as that found lining the intestines, is specialized for
absorption and secretion.
Which of these tissues, found in the lungs, permits gas exchange by diffusion?
simple squamous epithelium. This is a thin single layer of cells that allows for diffusion.
What type of epithelial tissue lines kidney tubules?
The simple cuboidal cells of kidney tubules allow for both secretion and absorption.
Which of the following lines organs that come into contact with the environment?
Occurring in sheets of tightly packed cells, epithelial tissue covers the outside of the
body and lines organs and cavities within the body.
Epithelial tissues include _____.
squamous, cuboidal, and columnar cells
The apical surfaces of many epithelial cells in the respiratory system have
__________.
modifications called cilia. Projections called cilia are found on the apical surfaces of
some cells and help move materials along the epithelial surfaces
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. for example, to hold
organs in place
, _____ is the connective tissue specialized for transport.
Blood is specialized for the transport of substances such as nutrients, wastes, and
gases.
Connective tissue __________.
consists of cells scattered in an extracellular matrix
Connective tissue consists of a population of cells embedded in an extracellular
matrix. What is the extracellular matrix associated with blood?
plasma. Blood is suspended within a liquid extracellular matrix known as plasma. It
consists of water, salts, and dissolved proteins.
Which of the six major types of connective tissue has a rigid matrix made of
collagen and calcium salts?
bone
What is the primary function of loose connective tissue?
holding other tissues and organs in place. The matrix of loose connective tissue is a
weave of fibers in a watery fluid that aids in its function.
What type of muscle is responsible for the involuntary contractions of the
digestive tract and arteries? non striated
smooth muscle
Cardiac muscle is the only muscle composed of _____ fibers.
branched
Skeletal muscles are attached to bones by _____, which are made of _____.
tendons ... fibrous connective tissue
Muscle cells contract. This is possible because of __________
contractile proteins
Voluntary body movements involve _____.
Skeletal muscle is generally responsible for voluntary movements. In humans, it is
attached to bones by tendons and allows the bones (and thus the body) to be moved.
striated.
Branched and striated is a description that would apply to which kind of animal
tissue?
cardiac muscle
A neuron consists of _____.
dendrites, a cell body, and axons
Nervous tissue functions _____.
to sense stimuli and transmit info
Which of the following is the primary function of the nervous tissue?
rapid communication of signals
Which of the following tissues is responsible for food absorption in the small
intestines?
columnar epithelium. This tissue secretes digestive juices and absorbs nutrients.
Columnar epithelium is arranged into fingerlike projections to increase the surface area
for absorption.
Which organ system regulates the water balance of the blood?
Urinary (especially kidney)
In what organ system do hormone-producing organs belong?
endocrine system
