Biology 1202 Chapter 40 (Exam 4 for Gregg Animal form and function) Questions and
Answers| New Update with 100% Correct Answers
What physical laws constrain animal form? Physics of exchanging materials with
environment; needs to take up food and get rid of waste. A concept of exchange.
How do simple organisms exchange material? by diffusion and entire plasma membrane is
exposed to medium
Why can't a giant amoeba survive on earth? too much volume compared to surface area
and not enough exchange to maintain the organism
Epithelial tissue covers the outside of the body and lines the organs and cavities, provides a
barrier, different epithelial tissues with different functions and shapes
Connective tissue bind and support other tissues; composed of sparsely packed cells
scattered throughout an extracellular matrix
What are some examples of epithelial tissues? stratified squamous, cuboidal, simple
columnar, simple squamous, and pseodostratified columnar
Loose connective tissue Skin; Connective tissue that lacks great amount of collagen or elastic
fibers (hence, loose), e.g., adipose tissue and areolar (general connective) tissue.
Adipose tissue Stores lipids for energy, insulation and cushioning
Fibrous connective tissue in the ligaments, densely packed collagen fibers; connect bones
and such
What are some examples of connective tissues? Loose connective, adipose, fibrous
connective, cartilage, bone and blood
, Muscle tissue Composed of long cells called muscle fibers and contracts/expands in
response to nerve cells
What are the three types of muscle tissues? Skeletal, cardiac and smooth
Which muscle tissue is voluntary? Which are involuntary? Skeletal (voluntary), Cardiac and
smooth muscle tissues are voluntary
Where can cardiac muscle be found? The heart, which pumps blood throughout the
circulatory system
Smooth muscle tissue can be found where? Lining of organs.
What is different about the smooth muscle tissue from the cardiac and skeletal muscle tissue?
It is not striated.
What is the function of the nervous tissue? sense stimuli and transmits signals throughout
the body
What are nerve cells made of? Excitable cells that sends an action potential to respond to
stimuli
What nerve cell is responsible for transmitting and receiving? Neuron
What nerve cell does not transmit information but for support? Glial cells
A system that is slow in response, but long lasting. It releases chemicals that circulate body and
get to their target cell. And stay in the body for a while Endocrine system
