1. Unit 10 Review
Body systems Test

2. Section 1 - The Brain
What are the four lobes to the brain and what are the functions?
Parietal Lobe = Sensory information / pain / touch
Occipital Lobe = Vision only
Temporal Lobe = Visual memories / emotions / hearing
Frontal Lobe = Critical thinking / personality

3. Section 1 - The Brain
What are the four lobes to the brain and what are the functions?
Cerebrum = largest portion of the brain , processes information
Cerebellum = Balance / Coordination / fear
Brain Stem = Regulates basic function – heart rate, breathing, swallowing, vomiting

4. Section 1 – The Brain Draw and label a brain diagram. Parietal Lobe
Frontal Lobe
Occipital Lobe
Temporal Lobe

5. Section 1 - The Brain
What is the difference between the peripheral nervous system and the central nervous system?
Central
Peripheral
Brain
Spinal Cord
Function – processes information
All nerves outside of CNS
Controls reflex pathways as well
Function - Takes in information

6. Section 2 – Heart, Lungs, Blood
What are the functions of the parts of the blood?
Red blood cells = Carry oxygen and carbon dioxide around body
White blood cells = fight infection
Platelets = stops bleeding, very small
Plasma = liquid part of blood, mostly water
Formed Elements = Iron, calcium, potassium

7. Section 2 – Heart, Lungs, Blood
How are heart rate and breathing rate related to each other?
Heart rate increases with breathing rate (vice versa)
How does blood flow in arteries and veins?
Arteries flow AWAY from the heart , Veins flow TOWARD the heart
What does hemoglobin do for the red blood cells?
Iron helps bond oxygen and carbon dioxide to the RBC

8. Section 2 – Heart, Lungs, Blood
What is the structure of the heart?
4 chambers – 2 top = atria, 2 lower = ventricles
How does blood flow in the body?
Heart  lungs  heart  artery  capillaries (body)  veins  back to heart
How does exercise affect blood flow? How does arthrosclerosis affect blood flow?
Exercise increases blood flow and makes the heart muscles stronger, thus making it easier for blood to move. Arthrosclerosis restricts blood flow by blocking walls of arteries.

9. Section 3 – The Immune System
What are non-specific responses and specific responses in the immune system?
What are common effective methods humans can use to stop the spread of disease?
Keep things clean – use of chemicals / heat to kill pathogens, good sanitary habits, antibiotics
Specific
Non -specific
Specific cells = T Cells, B Cells, (Memory cells recognize pathogens and fight it off in the future)
Fever
Inflammation
Increased blood flow

10. Section 3 – The Immune System
How do vaccines work?
Antigens from a pathogen are removed from disease and given to the body so it can recognize future infections. Memory cells develop.
What do the mucus membranes do in the body?
Nose, ears, mouth, excretory organs covered. Catch and trap particles and prevent them from moving into the body further.

11. Section 4 – Sexual Reproduction
Know the major organs of the female and male reproductive systems
Female
Uterus = embryo develops here
Cervix = barrier to the uterus
Fallopian Tube = where fertilization occurs
Ovaries = produces the ova (eggs)
Vagina = entry/exit of reproduction system
Uterine Lining = where the fertilized egg attaches
Male
Testes = produces sperm
Epididymis = stores mature sperm
Vas Deferens = connects testes to urethra
Prostate Gland = produces semen
Urethra = carries urine and semen out
Penis = houses urethra

12. Section 4 – Sexual Reproduction
What is the purpose of the testes and the ovaries?
Testes produce sperm and testosterone. Ovaries produce eggs/ mature eggs and makes estrogen and progesterone.
What are the gametes of males and females?
Male = sperm , female = ova (ovum)

13. Section 4 – Sexual Reproduction
What does a fetus use the umbilical cord/placenta/and amniotic sac for?
Umbilical = connects products of blood with mother, Placenta = filters blood components, Amniotic sac = suspends the fetus for development to prevent damage.
What are the names/pattern of development from single cell to whole human?
Zygote (fertilized cell)  blastocyst  embryo  fetus  infant (only after birth)

14. Section 4 – Sexual Reproduction
What major events occur during each trimester of development?
Trimester 1 Trimester Trimester 3
Overall body structure is made
Arms, legs, head, body
Organs develop
Weeks
Fingers, toes, eyelids, lips form
Organs become more dense
Movement occurs
Weeks
Hair – skin transparent
Brain activity – dreams, hearing, sight
Organs develop
Weeks
