Terms in this set (28)
Which organs are found in the thoracic cavity?
Small and Large Intestines
Arrange the following structural terms by hierarchy from LOWEST TO HIGHEST(i.e. from most basic to most advanced):
Atom, molecules, organelles, cells, tissues, organs, organs system, organisms
The ___________ plane is the one cut through the midline of the body, equally splitting the left and right sides as viewed from the front.
This cavity is the largest of the body and contains the liver, stomach, intestines, and gallbladder.
Directionally, superior refers to
being higher (toward the head),
Inferior refers to
being lower (toward the feet).
is the study of disease that draws heavily on knowledge of Anatomy and Physiology for development of therapies and cures.
is the study of the structure of an organism and the relationships of its parts.
is the study of the functions of living organisms and their parts.
The fundamental building block of matter; also known as he lowest level of the hierarchy of life.
A covalently bonded groups of atoms
A bonded group of atoms that are comprised of different elements
The identity of a chemical species, which is determined by the number of protons in the nucleus.
Any atom that has a differing number of neutrons in the nucleus
Any atom that has a differing number of electrons in the orbitals it contains, resulting in an IMBALANCED CHARGE.
is associated with the sharing of electrons between two atoms to build a stable outer shell.
Are simply electrical attractions between ions of opposing charges.
An acids is where
a molecule that increases H+ in water,
Bases is where
is something that lowers H+ in water.
This class of molecules is primarily used for energy in the body and is comprised of monosaccharides, disaccharides, and polysaccharides.
This class of proteins is responsible for chemical activity and drives most of the homeostasis in the body by making reactions operate at high speed.
Lipids have a variety of functions in the body. What class of lipids are the primary structural unit of the cell membrane?
This class of molecules is the source of the genetic code, which is directly translated into protein by the organelles in the cell. It is comprised of nucleotides.
On the pH scale, acids have a
low value (close to 0).
have a high value close to 14.
have an intermediate value of 7 that resemble pure water in acidity.
Describe, in detail, the structure of the atom. A complete answer will include the subatomic particles, their locations and their roles in structure and function of the atom and the atom's identity.
Neutrons and protons in the nucleus, electrons in the outside. The number of valence electrons determine how reactive it is, like the molecule wants to achieve a full valenc electrons shell, so it will be more reactive if it's not filled. But if it's full, it'll be less reactive
Negative feedback loops are those that "oppose, or negate, a change in a controlled condition" in order to return to a homeostatic balance. Using the terms controlled condition, disturbance, sensor, integrator, and effector, provide a short description of a feedback loop example. It can be one we that we discussed in class, the text, or another accurate example.
Controlled conditions- body temperature decrease
Sensor- by cold temperatures
feed back- to actual body tem
Signals- normal body tem
Effector- muscles (shivers)
