population
27
It is the sum of populations inhabiting a particular area.
community
28
It is the collection of all ecosystems, and it represents the zones of life on earth.
biosphere
29
4 basic types of tissues
1. epithelium 2. connective 3. muscular 4. nervous
30
Type of tissue that forms the coverings of surfaces of the body.
epithelium
31
Functions of epithelium:
1. protection 2. adsorption 3. excretion 4. secretion 5. filtration 6. sensory reception
32
Characteristics of epithelium
1. Polarity 2. Cellular nature 3. Supported by connective tissue 4. Avascular 5. Regeneration
33
Polarity in epithelium means that it is arranged with one free surface (_______) and one attached surface (_______).
apical surface; basal surface
34
Cells in epithelium fit closely together side by side and sometimes atop each other to form sheets of cells. These sheets are held together by specialized junctions.
Cellular nature
35
True or False. Epithelium is supported by muscle tissue.
False. supported by CONNECTIVE tissue
36
It means epithelium typically lacks its own blood supply.
Avascular
37
True or False. Epithelium cells can regenerate if proper nourished.
True
38
Attachment to a layer of connective tissue at the basal surface forms a layer called the _______, an adhesive layer formed by secretions from the epithelial cells and the connective tissue cells.
basement membrane
39
Arrangements of epithelium
1. Simple 2. Stratified 3. Pseudostratified 4. Transitional
40
Cells are found in a single layer attached to the basement membrane.
Simple
41
Cells are found in 2 or more layers stacked atop each other.
Stratified
42
A single layer of cells that appears to be multiple layers due to variance in height and location of the nuclei in the cells.
Pseudostratified
43
Cells are rounded and can slide across one another to allow stretching .
Transitional
44
Shapes of epithelium
1. Squamous 2. Cuboidal 3. Columnar
45
Flat, thin, scale-like cells.
Squamous (Latin: squamascale)
46
Cells that have a basic cube shape. Typically the | cell's height and width are about equal.
Cuboidal
47
Tall, rectangular or column-shaped cells. Typically taller than they are wide.
Columnar
48
Hair-like appendages attached to the apical surface of | cells that act as sensory structures or to produce movement.
Cilia
49
These are specialized cells that produce mucus to lubricate and protect the surface of an organ.
Goblet cells
50
Are finger-like projections that arise from the epithelial layer in some organs. They help to increase surface area allowing for faster and more efficient adsorption.
Villi
51
Are smaller projections that arise from the cell's surface that also increase surface area. Due to the bushy appearance that they sometimes produce, they are sometimes referred to as the brush border of an organ.
microvilli
52
_________ is the most abundant and widely distributed tissue type found in the human body.
Connective tissue
53
Function of connective tissue
1. protect 2. support 3. bind together parts of the body
54
Characteristics of connective tissue
1. Connective tissues tend to be very vascular (have a rich blood supply). Some exceptions, such as tendons, ligaments, and cartilages, are less vascularized. 2. Connective tissues are made up of many types of specialized cells. 3. Connective tissues contain a large amount of non-living material referred to as the matrix (composed of ground substance and fibers).
55
4 types of connective tissues
1. Connective tissue proper a. Loose Connective Tissue i. Areolar ii. Adipose iii. Reticular b. Dense Connective Tissue i. Dense regular ii. Dense irregular iii. Elastic 2. Cartilage a. Hyaline b. Elastic c. Fibrocartilage 3. Bone (osseous tissue) 4. Blood
56

Integumentary System
58
What organ system is this? -made up of all the bones in the human body, i.e., the skeleton.
Skeletal System
59
What organ system is this? -includes the different types of muscles
Muscular System
60
What organ system is this? -also known as the cardiovascular system, consists of the heart, veins, arteries, and capillaries. The circulatory system circulates blood throughout the body in order to transport nutrients and oxygen to the cells.
Circulatory System
61
What organ system is this? -made up of the organs used for breathing, including the lungs, diaphragm, trachea, bronchi, and bronchioles.
Respiratory System
62
What organ system is this? -digests food and absorbs it into the body.
Digestive System
63
What organ system is this? -gets rid of wastes from the body in the form of urine.
Urinary System
64
What organ system is this? -an organism’s defense system; it protects against disease.
Immune System
65
What organ system is this? -sends and interprets signals from different parts of the body and organizes the body’s actions.
Nervous System
66
What organ system is this? -comprised of all the glands in the body that produce hormones, which are carried via the bloodstream to affect other organs.
Endocrine System
67
What organ system is this? - includes an organism’s sex organs.
Reproductive System
68
________ is the act of keeping the internal environment of a living organism within an acceptable range of conditions.
Homeostasis
69
Homeostasis controls the following:
1. temperature 2. pH 3. blood volume 4. oxygen levels 5. blood sugar levels
70
Homeostatic mechanisms that maintain internal constancy are collectively known as _________.
