Exam 5: Part 2 Review

Prolactin: Stimulates milk production
Growth Hormone: Stimulates growth and medtabolism l

Thyroxine (T4): Increases metabolism and growth
Calcitonin: Lowers blood calcium lvls

Cortisol: Regulates metabolism
Aldosterone: Regulates sodium and potassium lvls

Thymosin: Promotes T-cell maturation

Estrogen: Develop female reproductive system
Progesteron: Same as above

Testosterone: Develops male reproductive system

Eat a meal
- Increase in blood glucose
- (Beta Cells) Pancreas releases insulin
- trigures cells to uptake glucose
- glucose stored as glycogen in the liver
- return to normal

Fasting
- Decrease in blood glucose
- (Alpha Cells) Pancrease relases glycogen
- Glycogen broken down into glucose
- Synthesis of glucose
- return to normal

Superior & Inferior Vena Cava -> Right Atrium -> Tricuspid valve -> Right ventricle - Pulmonary valve -> pulmonary arteries -> lungs -> pulmonary veins-> Left Atrium -> Bicuspid valve -> Left ventricle -> Aortic valve -> aorta -> Rest of body

1. Transportation (Ex. O2, CO2, Hormones, etc.)
2. Regulation (Ex. Body temp, pH, solute concentration, etc.)
3. Protection (Ex. against pathogens (bacteria & viruses) and blood loss)

Arteries
- thick walls
- high pressure
- blood away from heart

Veins
- thin walls
- low pressure
- blood to heart

Capilaiares
- single layer
- smallest blood vessel
- exchange of materials between cells and blood

Systolic
- Max BP achieved during ventricular contraction

Diastolic
- Min BP achieved during ventricular relaxation

Carries O2 & CO2

Aids in blood clotting

Responds to infections & injury

Help kill/neutralize parasites

Release histamine and heparin

Macrophages in tissues

Target/neutralize pathogens

Left ventricle -> Aortic valve -> aorta -> Subclavian artery -> Brachial artery -> arm
