Cards

Term
Cellular respiration
Definition
the process of converting glucose into ATP, it happens in the mitochondria of the cells
Term
protien
Definition
digestion begins in stomach with HCI and pepsin and then in small intestine with typsin from pancreas and peptidase form intestine glands
Term
starch
Definition
digestion begins with amylase from salivary glands and continues in small intestine wiht amylase from pancreas, ends with maltase from intestinal glands
Term
fats
Definition
begin with bile from the liver, makes fat into droplets and then lipase from pancreas converts them to fatty acids and glycerol
Term
heart
Definition
pumps blood to lungs to get oxygen and get rid of CO2/ pumps body to get nutrients and get rid of waste
Term
heart beat
Definition
Aria Ventricle Rest
Term
pace maker
Definition
sends out electrical shocks to mimic Sa and Av nods, can speed up or slow down heart beat
Term
SA nod
Definition
sends bloods from atria to ventricles
Term
AV nod
Definition
causes ventricles to contract forcing blood out of the heart
Term
purkinje Fibers
Definition
neural cells that carry impulses through the ventricular tissue
Term
LDL cholesterol
Definition
BADD deposits fatty particles in your blood vessels to block arteries
Term
HDL
Definition
good cholesterol caries fatty particles from your blood vessels
Term
LDL:HDL ratio
Definition
130;45 or below
Term
digestion
Definition
takes place in the small intestine food is broken down and absorbed into the capillary walls
Term
digestive system
Definition
salivary glands, gastric glands, pancreas, liver, small intestine
Term
body project
Definition
to help students with eating disorders
Term
atherosclerosis and what happens over time
Definition
when an artery is damaged because of HBP and the fats begin to deposit on the lining. Over time it can rip and blood clots will completly block it and everything downstream dies.
Term
systolic blood pressure
Definition
pressure generated on walls of artery while they are contracting, this pressure is higher
Term
diastolic Pressure
Definition
pressure whilethe heart is resting, pressure is lower
Term
Mediteranean diet
MEAT OILS FISH AND DAIRY
Definition
red meats only a couple times a month, poultry and fish couple times a week, oils fruits vegetables and dairy every day.
Term
lyon diet heart study
Definition
subjects placed on Mediterranean diet were less likely to have another heart attack
Term
blood pressure
Definition
normal 120/80 or below high is 140/90, higher can damage the artery walls
Term
moderate drinking
Definition
two drinks a day has a benefit of reducing risk of heart disease
Term
french paradox
Definition
french eat meals with high saturated fat but drink wine every meal so have less heart likely
Term
Why are women less tollerant
Definition
they produce less alcohol dehydrogenase, which helps process alcohol
Term
J shaped curve
Definition
risk vs rewards shown in drinking alcohol
Term
liver
Definition
detoxification of blood, it produces alcohol dehydrogenase to break it down
Term
alcohol induced liver disease
Definition
overworking of the liver because of the excess drinking
Term
ALD fatty liver and alcoholic Hepatitis
Definition
ALD can be reversed if abstinence from drinking
Term
ALD Cirrhosis
Definition
CHronic form of ALD, its permanent scaring of the liver cant be reversed. Leads to death
Term
epmphaseyma
Definition
smoke causes break down of alveolar walls so it has less surface area
Term
lung cancer
Definition
number one killer, carcinogens from smoke get caught in the lung and cause a mutation. undetectable
Term
cilia
Definition
lining of the respitory system that cleas up bacteria, smoking kills this
Term
Endocrine System components
Definition
Thyroid Pituitary and pancreas,
Term
endocrine system function
Definition
these glands produce hormones that travel thought the blood stream and control the function of other glands or cells
Term
pituitary gland
Definition
master gland, it produced hormones that control other glands through the body
Term
metabloism
Definition
how fast your body undergoes cellular respiration, its controlled by the thyroid and the pancreas
Term
thyroid system
Definition
it involves the pancreas and the thyroid gland, pancreas produces thyroid stimulating hormone and the thyroid produces thyroxine that controls metabolism
Term
negative feedback system
Definition
as thyroxin levels decrease the pancreas produces TSH, and vice versa
Term
Cretinism
Definition
Undeveloped thyroid:, thyroxin isn't produced enough to support fetal development. children are born small
Term
Simple goiter
Definition
thyroid cant produce thyroxine because lack of idoine, pituitary keeps producing TSH and it enlarges the thyroid.
Term
Diabetes
Definition
a problem in which our body digests food, it is a problem with our insulin system. People cant remove sugar from blood cells
Term
Insulin
Definition
pancreas produce it and it is needed by the cells in order to take sugar from the blood stream..it opens channels in the cells
Term
Type 1 Juvenile diabetes
Definition
autoimmune disease, more rare, pancreas is damaged by immune system and it produces to much insulin
Term
Type 2 adult onset ddiabetes
Definition
weight related cells become resistant to insulin and dont open the channels up
Term
effects of diabetes
Definition
sugar stays in blood stream and causes thick blood
Term
hemophilia
Definition
hereditary genetic disorders that impair the body's ability to control blood clotting
Term
glycerols attached to 3 fatty acids
Definition
fat
Term
two complex sugar
Definition
starch and cellulose
Term
venous end of the capillary
Definition
carbon dioxide, wastes and water move back into the capillary
Term
arterial end
Definition
oxygen, amino acids and glucose come out of the capillary
Term
Amonia
Definition
most serious side effect of cirrhosis is that liver becomes unable to convert amonia into urea
Term
hepatic Coma
Definition
the buildup of ammonia in the bloodsteam can leat do a hepatic coma and death
Term
bing drinking
Definition
5 or more drinks on any occasion
Term
difibulator
Definition
stops the heart so it can reboot
Term
capillary system
Definition
he smallest of the body's blood vessels. Oxygen and glucose pass through capillary walls and enter the cells. Waste products such as carbon dioxide pass back from the cells into the blood through capillaries.
Term
why a scientist would “run a gel.”
Definition
When they need to sort Dna, the dna will sort itself in sizes when it is run through a gel
Term
Where does the mRNA go after transcription
Definition
ribosomes
Term
DNA pairs
Definition
T&A C&G
Term
Angioplasty
Definition
It involves pulting up the artery mechanically and putting a thin mesh tube in it to keep it open.
