CSA#4 REVIEW
HUMAN BODY, SOUND,
LIGHT
CHAPTER 1: HUMAN BODY
• Lesson 1: Body Organization
– Cell
– Nervous, muscular, skeletal systems
• Lesson 3: Homeostasis
– The process in which the body maintains a stable
internal and external environment
CHAPTER 2: BONES, MUSCLES
AND SKIN
• Lesson 1: The Skeletal System
– Shape and support, movement and protection,
production and storage of substances
– Red and yellow bone marrow
– joint
• Lesson 2: Muscular System
– Muscle
– Skeletal muscles
– One muscle shortens and contracts while the other
muscle relaxes and lengthens (ex. bicep, tricep)
– Cardiac muscle
CHAPTER 3: DIGESTION
• Lesson 3: The Digestive Process Begins
– Digestion, absorption and elimination
– Waves of involuntary muscle contractions that push
food through the digestive system
• Lesson 4: Final Digestion and Absorption
– Water is absorbed, which dries the digested food
before it is eliminated from the body
– Make bile, store vitamins and minerals, clean blood
– By absorption in the small intestine
CHAPTER 4: CIRCULATION
• Lesson 1: The Body’s Transport System
– Deliver materials, remove wastes, regulate body
temperature, fight disease
– Heart, blood vessels (arteries, capillaries, veins)
• Lesson 3: Composition of Blood
– Red blood cells, white blood cells, platelets,
plasma
– Red blood cells carry oxygen to cells, white blood
cells fight disease, platelets stop bleeding, plasma
is the liquid portion of the blood
CHAPTER 5: RESPIRATION AND
EXCRETION
• Lesson 1: The Respiratory System
– Process in which the body breaks down glucose
using oxygen to produce energy
– Carbon dioxide, water, energy
• Lesson 3: The Excretory System
– Removal of wastes from the body
CHAPTER 7: THE NERVOUS SYSTEM
• Lesson 1: How the Nervous System Works
– Receiving information, responding to information,
maintaining homeostasis
– Nervous system
CHAPTER 8: ENDOCRINE AND
REPRODUCTION
• Lesson 1: The Endocrine System
– A chemical produced by an endocrine gland that
travels through the blood to turn on, turn off, speed
up or slow down the activities of organs and tissues
• Lesson 2: The Male and Female Reproductive
Systems
– Testes
– Ovaries
– Male: testes, urethra, vas deferens, scrotum, penis.
Female: ovaries, fallopian tubes, uterus, vagina,
cervix
SOUND AND LIGHT:
CHAPTER 1: SOUND AND LIGHT-CHARACTERISTICS OF WAVES
• Lesson 1: What are waves?
– A disturbance involving the transfer of energy from place to
place
– When energy travels through a medium
– Crest, trough, rest position, wavelength, amplitude
– Waves in which the medium vibrates in the same direction in
which the energy travels
– A wave that vibrates the medium perpendicular to the direction
the energy is traveling
• Lesson 2: Properties of Waves
– The distance between adjacent crests or troughs
– The wave height (measured from rest position line to the top of
the crest or the bottom of the trough)
CHAPTER 2: SOUND
• Lesson 1: The Nature of Sound
– Light waves travel much faster than sound waves
– Longitudinal wave (sound wave)
– The sound waves bend to go around the edges of an
opening, such as a doorway
• Lesson 2: Properties of Sound
– An event where the motion of a sound source causes
the sound waves to either get closer or spread out
– Pitch: a description of how high or how low a sound is
– Loudness: the extent to which you can hear a sound
CHAPTER 3: ELECTROMAGNETIC
WAVES
• Lesson 1: The Nature of Electromagnetic
Waves
– Electromagnetic waves
– medium
• Lesson 2: Waves of the Electromagnetic
Spectrum
– Made up of radio waves, microwaves, infrared
rays, visible light, ultraviolet rays, x-rays and
gamma rays
CHAPTER 4: LIGHT
• Lesson 1: Light and Color
– Red, blue, green
– Black
– It would absorb all of the wavelengths, and not reflect
any colors
• Lesson 2: Reflection and Mirrors
– Happens when light waves bounce off of an object
– Bending of light waves when they enter a new
medium
– Sound waves going around corners
CHAPTER 4: LIGHT (CONT.)
• Lesson 3: Refraction and Lenses
– It refracts, or bends, and travels at a different angle
than before
• Lesson 4: Seeing Light
–
–
–
–
–
–
Transparent front surface of the eye
Ring of muscle that changes the size of pupil
Opening through which light enters the eye
Layer of cells lining the inside of eyeball
On the retina
Respond to different colors, send impulse to brain
