• Identify and/or explain the basic functions of
the human immune system, including specific
and nonspecific immune responses.
• Describe how the human immune system
responds to vaccines and/or antibiotics.
How does the immune system protect
humans from disease?
• Nonspecific Defenses
▫ Skin
▫ Mucus, saliva, and tears
▫ Fever (Pathogens can only survive in a small temp. range)
▫ Inflammatory Response- The immune system produces millions
of white blood cells.
 Many white blood cells are phagocytes, which engulf
and destroy bacteria.
• Specific Defenses
▫ Antibody- A protein that binds to molecules on
pathogens to inactive the pathogens.
 Antibodies attach to and inactivate viral particles that
have not yet entered body cells
 B cells produce antibodies
How does the human immune system
respond to vaccines and antibiotics?
• Vaccines contain a dead or
weakened form of the disease
causing microorganisms.
– This causes the body to produce
antibodies and remember the virus
• Antibiotics- fight bacterial
diseases by killing /slowing the
growth of bacteria.
Immune System
• Key Vocabulary: antibiotic, antibody, antigen,
communicable disease, pathogen, vaccine,
vein, vascular tissue
Biology Review L.14.36 – Blood Flow
Describe the factors affecting blood
flow through the cardiovascular
system.
• Identify factors that affect blood flow and/or
describe how these factors affect blood flow
through the cardiovascular system.
How do factors such as genetics, nutrition
and behavior affect blood flow through
the cardiovascular system?
• Genetics- People can inherit genes that make
them more likely to have cardiovascular
disease.
• Nutrition- Eating healthy foods, low in fat, can
reduce your chance of plaque build up
(Atheroscelorsis) and heart disease.
• Behavior- Exercising and making healthy
choices (no smoking, etc) reduce your chance
of cardiovascular disease.
• HIGH Blood pressure can result if poor lifestyle
choices are made.
Blood Flow
• Key Vocabulary: anatomy, artery, blood flow,
blood pressure, capillaries, cardiovascular
system, homeostasis, physiology, vein,
vascular tissue

Biology Review L.16.13 – Human Reproduction
Describe the basic anatomy and physiology of the human
reproductive system. Describe the process of human
development from fertilization to birth and major changes
that occur in each trimester of pregnancy
• Identify and/or describe the basic anatomy
and physiology of the human reproductive
system.
• Describe the process of human development
from the zygotic stage to the end of the third
trimester and birth.
What are the important structures in the female and
male reproductive systems?
•
How do the male and female
reproductive systems work together to
create a zygote?
• Meiosis creates gametes in the male and
female reproductive systems.
– These gametes meet during fertilization and
create a zygote.
• Sperm path: testis epididymis  vas
deferens urethra
• Egg path: ovary  fallopian tubes  uterus
How does a human develop from a
zygote to a "full term" baby?
• First Trimester –
– Fertilization occurs
– Around week 5 heart, brain, and spinal cord develop
– At week 8 the embryo is now called a fetus
• Second Trimester –
– Continued development of all organ systems
• Third Trimester– Fetus gains weight, turns in the head down position
and prepares for birth
