- B1- Health
- Blood Pressure
- Normal Pressure = systolic/diastolic
- How strong blood is pumped in and out of the heart
- Pressure blood pushes on blood vessel sides
- Capillaries have very thin walls
- Heart Disease
- Cholesterol
- Salt
- Causes you to hold more water -> dilutes blood flow
- Carbon Monoxide
- Red Blood Cells have a greater affinity for CO than for O^2
- Smoking
- Nicotine narrows arteries
- Salt
- Cholesterol
- Malaria
- Infected Female Moquitos
- Lands and sucks the hosts's bloods
- Reproduces in liver
- Blood stream
- Cell bursts
- Blood stream
- Parasite
- Reproduces in liver
- Lands and sucks the hosts's bloods
- Infected Female Moquitos
- Defences
- White blood cells produce antibodies
- Attach to pathogens
- Then allow WBCs to locate and DESTROY
- Antibodies= a protein specificity
- Attach to pathogens
- White blood cells produce antibodies
- High Blood Pressure
- Age
- Genetics
- Weight
- Lots of Salt
- Lots of alcohol
- Drugs
- Stress
- Lack of exercise
- Healthy Diet
- EAR
- in g = 0.6 x body mass
- Estimated Average daily Requirement of Protein
- BMI
- Mass/ (Height)^2
- suger -> fat -> protein
- EAR
- Smoking
- CO
- Nicotine
- Tar
- Solidifies in alveolus
- Builds up
- = less Surface Area = less diffusion = less o2
- Builds up
- Solidifies in alveolus
- CO2
- Carcinogens
- Alcohol
- Depressant
- Brain damage
- inflamitory of gullet
- Liver
- inflames
- fatty
- cirrhosis
- Sugar Levels
- Diabetes
- TYPE 1
- Not enough insulin is produced
- TYPE 2
- Too much insulin
- TYPE 1
- Glucose
- insulin
- in the pancreas
- -> glycogen -> liver
- fats
- insulin
- Diabetes
- Blood Pressure
