State Standards
• SC.912.L.14.26 Identify the major parts of the brain on
diagrams or models. (LOW)
• Low Complexity 10%-20%
Low complexity benchmarks rely heavily on the recall and recognition of
previously learned concepts and principles. These benchmarks typically
specify what the student is to do, which is often to carry out a procedure that
can be preformed mechanically. It is not left to the student to come up with an
original method or solution. Skills related to low complexity benchmarks
include the following.
• Identify a common example or recognize a concept
• Retrieve information from a chart, table, diagram, or graph
• Recognize a standard scientific representation of a simple phenomenon
• Calculate or complete a familiar single-step procedure or equation using a
reference sheet

Moderate Complexity 60%-80%
Benchmarks in the moderate complexity category involve more flexible thinking and
choice among alternatives. These benchmarks require a student response that goes beyond
the habitual, is not specified, and ordinarily has more than a single step or thought process.
The student is expected to decide what to do – using informal methods of reasoning and
problem solving strategies – and to bring together skills and knowledge from various
domains. Skills related to moderate complexity benchmarks include the following.
Apply or infer relationships among facts, terms, properties, or variables
Describe examples and non examples of scientific processes or concepts
Predict or determine the logical next step or outcome
Compare or contrast structures or functions of different organisms or systems
Choose the appropriate formula or equation to solve a problem and then solve it
Apply and use concepts from a standard scientific model or theory

Students will identify factors that affect blood flow and/or describe
how these factors affect blood flow through the cardiovascular
system.
Cardiovascular Flow
• The Heart
• Blood flow:
o Artery & Vein composition
o Heart – flow of blood
o Blood pressure vs. osmotic pressure
o Skeletal muscle contraction
endothelium
smooth muscle
valve
connective tissue
ARTERY
VEIN
CAPILLARIES
arteriole
venule
Arteries, veins, and capillaries
transport blood to all parts of the body.
• Arteries carry blood away from the heart.
– blood under great pressure
– thicker, more muscular walls
• Veins carry blood back to the heart
– blood under less pressure
– thinner walls, larger diameter
– valves prevent backflow
• Capillaries move blood between veins, arteries,
and cells.
– One layer, one cell thick
• Blood pressure is a measure of the force of blood
pushing against artery walls.
– systolic pressure:
left ventricle
contracts
– diastolic pressure:
left ventricle
relaxes
• High blood pressure can precede a heart attack or stroke.
How the heart pumps
What makes the blood move
through the heart?
* cardiac muscle
* difference in thickness of wall
* valves
• Blood flow animation
• Besides the composition of the blood vessels, the heart,
and blood pressure, what else can affect the heart rate?
External factors?
Atherosclerosis
• a condition in
which an artery
wall thickens as a
result of the
accumulation of
fatty materials
such as
cholesterol.
• This is linked to
high fat diets and
lack of exercise.

• Immune System is a body system that fights
infection & prevents illnesses
• Immunity:
– the ability of the body to defend itself against
infectious agents, foreign cells, and abnormal
body cells (ex. cancer)
Line of Defense
• 1st Line: barriers
– Broad, external defense
• “Walls and Moats”
• skin & mucus membranes
• 2nd Line: Nonspecific patrol
– Broad, internal defense
• “Patrolling soldiers”
• phagocytes eating WBC’s
• 3rd Line: Immune System
– Specific, acquired immunity
• Elite trained units
• lymphocyte WBCs & antibodies
– B & T cells
1st line: Physical Barriers
•Non-specific defense
•External barriers
•skin –physically blocks pathogens
• mucus membranes- traps particles
in nose and throat
•excretions
•sweat
•tears
•mucus
•stomach acids
•saliva (“lick your wounds”)
Lining of trachea:

cells
2nd Line of Defense
Non-specific
Inflammatory reaction
–Four outward signs (redness, heat, swelling, & pain)
–Histamine is released which cause capillaries to
become enlarged
–and more permeable
–(causes redness,
–swelling, pain)
White Blood cells
Non-specific (macrophage)
3rd Line of Defense - Specific Defense
• Pathogens, cancer cells, or foreign cells have protein markers on
surface (antigens) that activate the immune system because
foreign to body
Types of White Blood Cells
- all made in the bone marrow
- All called in after the non-specific WBCs
–B lymphocyte cells (mature in bone marrow)
• produce antibodies that combine with antigens and target
particular pathogens
• Produce memory B cells
–T lymphocyte cells (mature in thymus gland)
• directly destroy infected cells
• produce cytotoxic T cells, helper T cells, and memory T
cells
Immunity
• Active
– Body creates an immune response after being
exposed to a pathogen or a vaccine
– Memory cells are produced so this immunity
lasts (sometimes even a lifetime)
• Passive
– Antibodies in breast milk or shots of antibodies
provide a temporary immune response
Different pathogen cause common infectious diseases
•Antibiotics kill pathogens inside the body
•antibiotics cause pathogens to burst
•target on specific bacterium or fungus
•not effective against viruses
• antibiotic resistance issues
Antibiotics have killed the bottom cell by
weakening its cell wall and causing it to
burst. (colored TEM; magnification
55,000X
• Antibiotic resistance can cause medicines to
become ineffective.
– Some bacteria in a population have genes that make
them immune to antibiotics.
– These bacteria spread the gene, making the antibiotics
useless.
A bacterium carries
genes for antibiotic
resistance on a plasmid.
A copy of the plasmid is transferred
through conjugation.
Resistance is quickly
spread through
many bacteria.
Vaccines artificially produce acquired immunity.
• Vaccines also control pathogens and disease.
– given to prevent illness
– contain the antigen of a weakened pathogen
• Vaccination provides acquired immunity.
– stimulates a specific

Allergies
• Our body releases histamine which makes vessels
leaky
• Histamine causes the mucus membranes of the
nose and eyes to release fluid as a defense against
pathogens
– This produces cold-like symptoms
• With anaphylatic shock, the capillaries become
so permeable that blood pressure drops

Male Reproductive System
Scrotum contains:
• Testes
– The seminiferous tubules produce sperm and
testosterone
– Require a low temperature
– Sperm live up to 72 hrs. in a female
• Epididymis - folds of tissue (700 ft long)
– Lies on top of the testes
– Sperm mature here with aid from helper sperm (mask
the 23 chromosome sperm from immune system)
• Vas deferens
– Connects the external scrotum to the internal pathway.
– Curves around the bladder, stores sperm, empties into the urethra
– Sperm travel through this during ejaculation
• Urethra
– glands including the prostate gland produce a fluid that combines
with the sperm to produce semen, enters here
– semen flows through the urethra along with sperm during
ejaculation (out the penis)
Female Reproductive system
(oviduct)
Female Reproductive System
• Ovaries - pair, internal
–

–
Mature and release one egg/month
Matures in the follicles within the ovaries
Born with all the eggs a female will ever have
2 million at birth; 200-400 thousand at puberty; 400 will
mature and be released
– Once the egg has been released by the follicles, the
follicles will release hormones for child development if
fertilization takes place
Female Reproduction
• Oviducts or Fallopian tubes
– Feathery like projections
– After ovulation (releasing of the egg) occurs, the egg enters one
of the oviducts
– This is where fertilization occurs as the egg only lives 6-24 hrs.
– The egg can’t move so it relies on cilia that lines the duct to
cause a current along with muscle contraction (cramps at
ovulation)
– Fertilized egg  zygote  embryo
• Uterus
– Embryo will embed itself in lining of uterus
• This causes a hormone to be released (+ pregnancy
test result)
– Embryo will develop into a fetus
– Uterus: 5 cm wide but expands to 30 cm
– Thick walled muscular organ above the bladder
• Cervix
– This opening connects the vagina to the uterus
– Opening is usually 1 cm wide, but during birth, expands
to 10 cm
• Vagina
– Birth canal, site of sexual intercourse, site of
menstruation – acidic for immunity reasons
Fetal Development
The fertilized egg implants into the uterus and is
nourished by the placenta and umbilical cord.
• The zygote becomes a blastocyst and implants in the uterus.
