Why do biologists say that in physiology, form and function are related? Be able to give some
examples of this. (40.1) - (ANSWER)They say that the form of the animal (which is the size and
shape), can affect the physiology of the animal and the way that it interacts with the
environment. For example, Seals and fish have more streamlined bodies so that they can cut
through dense waters without much energy use.
What sorts of substances do organisms need to be able to exchange with their environments?
Why is this easier for single-celled organisms than for multicellular organisms? (40.1) -
(ANSWER)They must be able to exchange nutrients, waste, and gases with their (has to be
aqueous) environment. This is easier for single-celled organisms, because they merely don't have
as much surface area as multicellular organisms, and so it is easier to facilitate an aqueous
environment to conduct nutrient exchange for singular-celled organisms.
What do physiological structures specialized for exchange tend to look like? (40.1) -
(ANSWER)In most animals, exchange surfaces are specialized cells located in the body,
arranged in a way that protects tissues from abrasion or dehydration, and also maxim izes surface
area with their respective environment.
,What are the 4 basic tissue types? (40.2) - (ANSWER)Epithelial, connective, muscle, and
nervous
What are the 5 types of epithelial tissue cells? (40.2) - (ANSWER)Simple squamous, simple
columnar, simple cuboidal, stratified squamous, and stratified columnar/cuboidal
What are the 6 types of connective tissue cells and the function of each? (40.2) - (ANSWER)-
Loose connective binds epithelial cells to underlying tissues (also holds organs in place).
- Fibrous connective tissues are mostly found in tendons and ligaments, connecting bones to
joints.
- Bones are merely mineralized connective tissue that make up the skeleton of vertebrates.
Osteoblasts deposit a matrix of collagen, making repeating units called osteons, that have
concentric layers of the matrix, deposited around a central canal w/ blood and nerves.
- Adipose tissue stores fat in adipose cells that are distributed throughout its matrix.
- Cartilage, containing collagenous fibers in chondroitin sulfate, is a support material for
skeletons of vertebrate embryos. Some remain in adult vertebrates, such as the disks in the spine
that act as cushions between vertebrae.
What are the 3 types of muscle tissue cells? Which are voluntary and which are involuntary?
(40.2) - (ANSWER)Skeletal (striated) muscle controls all voluntary movements. They are
usually attached to bones, via tendons. Smooth muscle, found in digestive tract walls, urinary
, bladder, arteries etc., are usually controllers of involuntary body activities, like digestion or
vasoconstriction. Cardiac muscle (which is involuntary), forming the heart walls, relay signals
and synchronize heart beats through intercalated disks.
What are the 2 types of nervous tissue cells and their functions? (40.2) - (ANSWER)Neurons,
the basic unit of the nervous system, receives and transmits impulses to other neurons, muscles,
or other cells via axons. Glia helps "take care" of neurons, and sometimes modulates neuron
function as well.
What are the two communication systems used within the body? How do they differ from each
other? What are the chemical signals used by each called? (40.3) - (ANSWER)The endocrine
system sends signals to other parts of the body through hormones, chemicals that are released in
the bloodstream and are circulated until the target cell is reached. Meanwhile, the nervous system
uses neurons to transmit electrical impulses along comm. lines (axons) to specific locations of
the body.
Homeostasis is merely the idea of maintaining a state of internal balance. It requires maintaining
a decently constant environment that the body can function optimally in, despite external
environment changes. - (ANSWER)What does the word homeostasis mean? Does it involve
keeping conditions in the body exactly the same at all times? (40.3)
