1. Cell Types

2. Instruction:
Arrange the words according to the levels of
biological organization.
Organ system organism tissuecell

3. Biological Levels of
Organization

4. Four Main Types of Cells
 Epithelial Cells
 Connective Tissue Cells
 Muscle Cells
 Nerve Cells

5. Epithelial Tissue
 This type of tissue is commonly seen outside
the body as coverings or as linings of organs
and cavities.
 They are characterized by closely-joined cells
with tight junctions (i.e., a type of cell
modification).
 Being tightly packed, tight junctions serve as
barriers for pathogens, mechanical injuries,
and fluid loss.

6. Cells that make up epithelial tissues can
have distinct arrangements:
 Cuboidal
 Simple Columnar
 Simple Squamous
 Stratified Squamous
 Pseudo-stratified Columnar

7. Cells that make up epithelial tissues can
have distinct arrangements:
 Cuboidal
 For secretion
 Ex: salivary
and sweat
glands

8. Cells that make up epithelial tissues can
have distinct arrangements:
 Simple Columnar
 Brick-shaped cells;
for secretion and
active absorption
 Ex: stomach and
intestines

9. Cells that make up epithelial tissues can
have distinct arrangements:
 Simple
Squamous
 Plate-like cells; for
exchange of
material through
diffusion
 Ex: blood vessels

10. Cells that make up epithelial tissues can
have distinct arrangements:
 Stratified Squamous
 Multilayered and regenerates quickly; for protection
 Ex: outer layer of the skin (epidermis)

11. Cells that make up epithelial tissues can
have distinct arrangements:
 Pseudo-stratified
Columnar
 Single layer of cells; may
just look stacked because
of varying height; for lining
of respiratory tract; usually
lined with cilia (i.e., a type
of cell modification that
sweeps the mucus).

12. Connective Tissue
 Blood
 Connective Tissue
Proper (CTP)
 Cartilage
 Bone

13. Connective Tissue
 Blood
 Made up of plasma;
contains water, salts, and
dissolved proteins;
erythrocytes that carry
oxygen (RBC), leukocytes
for defense (WBC), and
platelets for blood clotting.

14. Connective Tissue
 Connective Tissue Proper (CTP)
 Made up of loose connective tissue that is
found in the skin and fibrous connective tissue
that is made up of collagenous fibers found in
tendons and ligaments.
 Adipose tissues are also examples of loose
connective tissues that store fats which
functions to insulate the body and store energy.

15. Connective Tissue
 Connective Tissue
Proper (CTP)

16. Connective Tissue
 Cartilage
 Characterized by collagenous
fibers embedded in chondroitin
sulfate.
 Chondrocytes are the cells that
secrete collagen and
chondroitin sulfate.
 Cartilage functions as cushion
between bones.

17. Connective Tissue
 Bone
 Mineralized connective tissue
made by bone-forming cells
called osteoblasts which
deposit collagen.
 The matrix of collagen is
combined with calcium,
magnesium, and phosphate
ions to make the bone hard.
 Blood vessels and nerves are
found at a central canal
surrounded by concentric
circles of osteons.

18. Muscle Tissue
 These tissues are composed of long cells
called muscle fibers that allow the body to
move voluntary or involuntary.
 Movement of muscles is a response to signals
coming from nerve cells.

19. Three Categories in Muscle
Tissue (In Vertebrates)
 Skeletal
 Cardiac
 Smooth

20. Three Categories in Muscle
Tissue (In Vertebrates)
 Skeletal
 striated; voluntary
movement
 To generate force
to support
locomotion and
posture

21. Three Categories in Muscle
Tissue (In Vertebrates)
 Cardiac
 Striated with
intercalated
disk for
synchronized
heart
contraction;
involuntary.
 To pump blood

22. Three Categories in Muscle
Tissue (In Vertebrates)
 Smooth
 Not striated;
involuntary
 Can be found in
the intestines,
digestive tract
and blood
vessels
 For digestion
and nutrient
collection

23. Nervous Tissue
 These tissues are composed of nerve cells called
neurons and glial cells that function as support cells
 These neurons sense stimuli and transmit electrical
signals throughout the animal body.
 Neurons connect to other neurons to send signals.
 The dendrite is the part of the neuron that receives
impulses from other neurons while the axon is the part
where the impulse is transmitted to other neurons.
 Cell body – contains the nucleus and connects the
dendrites, which bring information into the neuron

24. Nervous Tissue

25. Direction: Match each general tissue category to the
appropriate feature. Write the letter of your choice before
each number.
