According to biological rules, what is the reason for our existance?
to survive, reproduce, and continue our existance
How many categories of tissue are there?
Which organ system secretes hormones
All matter is made of
Chemical Elements
The smallest piece of an element
Biological Hierarchy of Organization
Atom, Molecule, Macromolecule, Organelle, Cell, Tissue, Organ, Organ System, Organism
Cellular Respiration
Process by which we convert stored energy into a usable form
Internal constancy; Maintaining the right balance of conditions in ur body.
Positive Feedback Mechanism
The body reinforces a change; Promotes further change away from the set point.
Negative Feedback Mechanism
Controls the bodys activities to maintain homeostasis.
Homeostasis is important because
our bodies strive to stay within normal ranges for blood pressure, pulse, resp. rate, oxygen and carbon dioxide levels, nutrients, etc.

-Fluctuations form the basis of disease diagnosis.
In what ways are bones and blood both C.T.?
-Bone forms the skeleton upon which the whole body is built, and bones connect to eachother and connect your extremities to your trunk.

-Blood travels through the entire body and connects virtually every cell.
Epithelial Tissues
-Are like wrappings; Form all linings and coverings in the body
Which tissue are basically the bodys packing peanuts?
-Loose C.T. or Areolar Tissue

- It fills spaces between structures and is often specialized into a type of c.t. called adipose (fat)
Dense Fibrous C.T.
-Very strong and forms the tendons that anchor your muscles to your bones and the ligaments that anchor your bones to eachother.
A shock absorber in many joints where your bones meet.
3 Types of Muscle Tissue
1. Skeletal

2. Smooth

3. Cardiac
Skeletal Muscle
Provides body movement by attaching to 2 bones

-Voluntary Muscle
Smooth Muscle

-Located in the walls of most of your internal organs and blood vessels
Cardiac Muscle
-Located in the heart

-responsible for the contractions that pump blood throughout ur body.
Nervous Tissue
-Found in your brain, spinal cord, and nerves

-Sends signals to your organs and controls their actions

The __________ systems acts as a fast-acting control system for the body.
The _________ systems functions to produce blood cells
What covers an organ?
Visceral pericardium
__________ _________ line cavities.
Parietal serosa
The ability to sense changes in the environment and respond to them is a physiological ability known as:
If the human body temperature drops slightly below 37° C (98.6° F), what occurs?
If the human body temperature drops below 37° C, metabolic reactions become slower.
