way to explain directional

terms. Just like a compass’s

the eight directional terms

are used to describe the

locations of structures in

Directional Terms

Directional terms are used to describe exactly where one body structure is in relation to another. They are used as-suming that the body is standing with feet only slightly apart and the palms facing forward (called the anatomical

position)

Superior = towards or at the upper part

of a structure

inferior = towards or at the lower part

of a structure

Anterior = towards or at the front of a

body

Posterior = towards or at the back of

the body

Medial = Towards or at the midline of

the body/ on the inner side

Lateral = Away from the midline of the

body/ on the outer side

Each directional term often has a counterpart with converse or opposite meaning. These terms are very useful when describing the locations of structures.

Structure & Function

Our bodies are made up of layers, and in those

layers lay several different structures that humans

need. Without them, we wouldn’t be able to sur-

vive. The major aspects of human physical structure

are : Responsiveness, Conductivity, Immune, Circu-

latory, Integumentary, Growth, Secretion, Absorp-

tion, Reproduction, Respiratory, Excretory, Muscu-

lar, Skeletal and Digestive.

Each one has a job all it’s own and they all coexist

with one another. The Digestive system cannot

function without the Excretory system just as the

Circulatory system wouldn’t work without Absorp-

tion. The Integumentary system keeps our exterior

apart from the interior. The Immune system stops

viruses and harmful bacteria from destroying us. The

Skeletal system our body upright and protects our

organs. Our muscular system keeps us moving and

pushes our involuntary muscles. Our Digestive sys-

tem turns food into waste and spreads nutrients

throughout the body. Circulatory pumps blood

through our veins. Respiratory fills our lungs with

oxygen. Excretory removes unwanted waste. And

Reproduction helps create more life so that our

race and continue and grow with all of our advanced

structures and functions.

Our bodies are sensitive and need proper

care in order for them to keep working

on a regular basis. Eating healthy, means

making it easier on your digestive system,

breathing regularly means providing your

muscles with oxygen, and keeping in

shape helps put ease on your bones,

muscles, and heart. Its easy to see if your

outside is working regularly but if you're

not certain about how your insides are

doing, it is important to see a doctor

immediately. He can check for

irregularities or growths and make you

happy and healthy once more!

French physiologist, Claude Bernard

Homeostasis

In the 1800s, French physiologist, Claude Bernard came to

a realization that would begin studies on homeostasis. He

observed that body cells survived in a healthy condition

only when the temperature, pressure, and chemical

composition of their fluid environment remained relatively

constant. He noted that although our the environment

outside of the cells was constantly changing (ex: weather),

the internal environment (ex: body temperature) remained

stable. The reason being that every regulatory mechanism

of the body existed to maintain constant equilibrium of the

human body’s internal environment, also known as

homeostasis. The term homeostasis was coined by

American physiologist Walter B. Cannon. “Homeostasis is

the ability to maintain relatively stable internal conditions

despite a changing external environment. Dynamic state of

equilibrium, or balance. The body is said to be in

homeostasis when its cellular needs are adequately met

and functional activities are occurring smoothly. Virtually

every organ system plays a role in maintaining the internal

environment.” Examples of homeostasis:

- temperature regulation

- Regulation of blood carbon dioxide level

- Regulation of blood glucose level

The human body is organized systems working

together to maintain equilibrium & good health,

essential to continue living.

There are seven structural levels:

Chemical level: includes all chemical substances

(atoms, ions, & molecules) necessary for life.

Organelle level: organelles are considered "tiny

organs" within a cell. Organelles are made of

molecules, and molecules are made of atoms.

Organelles have specific functions within living

cells.

Cellular level: cells are the basic structural and

functional units of the human body & there are

many types of cells (ex: muscle, nerve, blood)

Tissue Level: A tissue is a group of cells that

perform a specific function and the basic types of

Human Organization

tissues in the human body include epithelial,

muscle, nervous, and connective tissues

Organ level: an organ consists of 2 or more

tissues that perform a particular function (ex:

heart, liver, stomach)

System level: an association of organs that

have a common function; there are 11 major

systems in the human body; digestive, nervous, endocrine, circulatory, respiratory,

urinary, reproductive, muscular, lymphatic,

skeletal, and integumentary.

Organism level: this level describes how our

body is able to perform acts that aide in our

survival.

Anatomical Planes

The midsagittal plane is the plane that passes vertically through the body, dividing it

symmetrically into left and right halves. It passes through the midline structures such as

the spine and navel.

The transverse plane is the plane

that passes horizontally through

the body at right angles to the

midsagittal and frontal planes. IT

divides the body symmetrically into

upper and lower halves.

physiologist to the other, depend-

looked at and by the way the life

The most important in humans are

described as the follows:

Responsiveness– or irritability is that

environment. Withdrawing from a

Conductivity– refers to the capacity

of living cells and tissues to seletiv-

processes that result in

the absorption,

transport, utilization, or

exchange of respiratory

gases between an

organism and its

Digestion– is the process

by which complex food

products are broken

that can be absorbed

body cells.

Absorption– refers to the

stances, such as di-

gestive juices and

hormones, for di-
