16
Role of Hypothalamus: (
NS = Nervous System, ES = Endocrine System)
Hypo- Hypo what?? We never learned this Uday...
link between NS & ES ...controls Pituitary

What is the definition of homeostasis?
To maintain a stable, almost constant external environment
The neurological ability to think
Two of the answers are correct
To maintain a stable, almost constant internal environment
19
Why is oxygen essential for our ability to live?
Because it kills deadly pathogens, thus helping us live
Is energy for cells, allows them to carryout their functions
It is what's keeping the sky from falling
Because the government says so
20

Bro I don't know most of this, I'm gonna try to study more
Almost, maybe need a bit more practice
I'll try to study, But I always procrastinate
Bro this is easy money
21
How are Vaccines and Antibiotics DIFFERENT?
Vaccines do not prevent disease while Antibiotics do prevent
Vaccines are for bacteria, Antibiotics are for viruses
Vaccines are for viruses, Antibiotics are for bacteria
Antibiotics can be used as cancer cure, vaccines cannot.
22
How are vaccines and antibiotics
SIMILAR
?
Both kill viruses
Both aid pathogens in infecting the host/organism
Both aid immune system
Both prevent disease
23
What causes a fever?
Constipation is the main cause for fever
A concussion
THe presence of pathogens in the body
A hurtful comment
24
What are the two main glands of the Endocrine system?
Hypothalamus and Thymus
Hypothalamus and Pancreas
Pancreas and Thyroid
Hypothalamus and Pituitary
25
"Defends body from pathogens" which body system is being described?
Mall Cop system
Endocrine
Nervous
Immune
26
What is melanin, what does it do to protect us?
Pigment that absorbs Mr.Reynolds homework, so you don't burn
Pigment in your skin, absorbs U-V light so you do not burn
Melanin is located in the Hypothalamus and excretes hormones
Melanin is an organ near the kidney, that helps filter waste
27
How do the
Respiratory
and
Circulatory
systems work together? (
R = Respiratory, C= Circulatory)
R inhales O2 needed by cells. Exhales CO2, waste from cells
All of the answers are correct
C moves blood with O2 & energy to cells
C moves blood to Ks to be filtered
