Lesson 9
Types of animal tissues
and human organ
systems
A-Review
A1. What are tissues made of?
A2. Tissues are made of many cells
A3. What are the 3 main tissues in
plant?
1. Dermal
2. Ground
3. Vascular bundles
B- Types of animal tissues
B1. There are
4 main types
of tissues
B2.These
tissues are
found in
many
different
animals, not
just in human
C- 4 types of animal tissues
1.Epithelial
2.Muscle
3.Nervous
4.Connective
Tissue
Locations
line the body's
surface (skin)
and between
internal
organs (small
intestine, lung,
1.Epithelial esophagus)
Function
Example type
create barrier
to protect
body, absorb
and secrete
substances
a. skin
epithelia
b. columnar
epithelia in small
intestine with cilia
to absorb food
and secrete
mucous
2. Muscle
specialized for
voluntary and
involuntary
movement of
various organs
skeletal
muscle (look
striped)
Cardiac muscle
(unevenly striped,
found only in
heart)
Appearance
Tissue
3.
Nervous
Locations
Function
Brain
made of neurons,
receive and
transfer signals,
coordinate body
actions
bone,
fat,
4.
Connective blood
support,
protection,
binds cells
and tissues
Example type
Nervous
tissue
Bone
(calcium
hardened
tissue)
Fat (adipose
tissue)
blood (attack
invader,
transport
nutrients and
O)
Appearance
E- 11 human organ systems
Organ
Organ systems
E1. What made up tissues? Organs? Organ
systems? Body?
F-General functions of some typical
human organ systems
F1. Immune system:
F2. defend body against infections
F3. Endocrine system:
F4. produce hormones, act together with the
nervous system to keep body in balance
F5. Integumentary system:
F6. skin, hair and nails that creates a barrier
around the body
Etc.
• Full list can be studied on p 96 of your textbook
G- Focus on
G1. Digestive system
G2. Circulatory system
G3. Respiratory system
H- Digestive system
H1. Mechanical + chemical
digestion gives proper
digestion of food
H2. Fate of food:
H3. Start in mouth:
H4. Teeth grind food
(mechanical digestion)
into smaller pieces
H5. Enzymes in saliva
chemically digest food
H6.Partially digested food
then pass through
pharynx then esophagus
then stomach
H-Digestive system
H7.In stomach:
H8.Stomach is a muscle that further
churns the food (mechanical
digestion)
H9.Gastric juices + HCl + enzyme
pepsin secreted by stomach lining
further break down food to liquid
(chemical digestion)
H10.Liquidy food now passed on to the duodenum where
pancreas, liver and gall bladder release more enzymes
H11.The food are absorbed in the small and large
intestines
H12.Small intestine: 6-8 m long, has finger-like projections
called villi and microvilli for food absorption
H13.Bacteria E.coli live in large intestine
I-Circulatory system
I1.Functions: transports
nutrients and O2 to
cells and picks up
waste
I2.Arteries (red) carry
oxygenated blood
away from the heart
I3.Veins (blue) return
deoxygenated blood
to the heart
I-Circulatory system
What is O2 used for in animal cells?
Hint: glucose +O2  CO2 + water + energy
(Cellular respiration)
Which organelle use O2 to obtain energy?
Mitochondria
J- Blood flow in the heart
J1.Deoxygenated blood
from rest of body to
right atrium via superior
and inferior vena cava
 right atrium  right
ventricle  pulmonary
artery  lung where
blood picks up O2 
left atrium via
pulmonary veins  left
ventricle  oxygenated
blood left heart via
aorta to rest of the body
K- Try it yourself
1. Label AD in the diagram below.
2. Which kind of blood
(deoxygenated/oxygenated?) that
entering:
a. superior vena cava
b. pulmonary vein
c. pulmonary artery
d. aorta
3. Where does the blood come from before
entering the superior vena cava?
4. Where does the blood come from before
entering the inferior vena cava?
5. Where does the blood go to after leaving
the pulmonary artery?
6. The part receives blood from lung is:
a. left ventricle
c. left atrium
b. right atrium
d. right atrium
Everyone
Take 3 deep breath
Inhale…..
then, exhale…..
L- Respiratory system
L1.Function: brings in O2
and gets rid of CO2.
L2.Air enters nose 
pharynx  larynx
trachea  bronchi 
bronchioles (smaller
branches of bronchi) 
alveoli (tiny sacs on the
bronchioles)
L3.The very thin wall of
alveoli allows CO2 and
O2 to be exchanged
with the circulatory
system

N-Medical imaging technology
N1.The big idea: our society benefit greatly
from the advancement of medical imaging
technology
1.X-ray: what do you know about X-ray?
N2.X-ray image is basically a shadow:
radiation is shined on one side of the body,
and a piece of film on the other side
registers the shadow of the bones.
N3.absorbed by human body
N4.Huge benefits in dental and bone fracture
diagnosis
N5.Not without risk: can cause cancer and
mutate chromosomes if exposed
Dental X-ray

instrument
N-Medical imaging technology
2. CT or CAT scan
(CAT= computerized
axial tomography):
N6. X-ray beam rotates
around an area of the
body, generating 3-D
image of the internal
structures with the
help of a computer
CAT scan thin slice image of a
N-Medical imaging technology
3.Ultrasound
N7. high frequency sound waves
are transmitted through the skin
and reflected by the internal
organs
N8. These "echoes " form a
picture on a screen which can
be examined for any
abnormalities.
N9. This procedure avoids the
need to expose body to harmful
radiation such as x-ray
N- Medical imaging technology
4. Magnetic resonance
imaging (MRI) scan:
N10.Use strong magnetic
field and radio-waves
instead of harmful X-ray
MRI instrument
MRI image
N11.What are the
differences
between MRI and
CT scan?
N-Medical imaging technology
5. Endoscopy:
N12.Technique that use
a flexible tube that
has a small camera
on the end of it.
N13.This instrument is
called an endoscope
which is inserted into
the body via mouth,
anus or small cut
