• Plasma glucose flow chart
• Exam, Muscle, Cardiovascular, Endocrine system
• Bonus questions from exam 2 and exam 1 difficult endocrine system questions
• Capillary has limited stuff going between it
• Proteins in blood trapped in blood
• There are proteins in the interstitinal fluid
• Ultrafiltration, mediated transport, aquaporins- water transport
• Water movent is used to carry nutrients.
• Ultrafiltration enhances ability to deliver nutrients and pickup waste
• Where do nutrients come from? Glycogen→glucose (Liver) Digestive system Fatty acids
from fat cells.
• Urea comes from the liver
• Organs of excretion
o Kidneys- Water-soluble stuff. Kidneys cannot deal with proteins
o Liver- Puts stuff into bile→ intestines Fat soluble stuff. Liver can make stuff
water soluble.
• Regulation of systemic blood pressure
o Local blood pressure tends to be locally controlled
o Systemic is hormonally, nervous system can play some role
o Short-term changes Basoconstriction
o Long-term changes- Blood volume controlled via hormones in the kidney
• LONG TERM BLOOD REGULATION IS DUE TO WHAT?
• WHY DO DEHYDRATED PEOPLE HAVE LOW BP?- LOW VENOUS RETURN LOW BLOOD
VOLUME. LOW BP
• DECREASE HEART RATE
• SYMPATHETIC STIMULATION?
• PARASYMPATHETIC STIMULATION?

•
• Platelets- Cell fragments
• White blood cells are leukocytes- The immune system- Very prominent nucleus used to
determine one cell versus another
• Plasma- Water and everything dissolved in it, proteins, enzymes, carrier molecules for
lipid soluble stuff, immune system proteins, antibodies
• Hematocrit- % RBC
• Plasma serum- derived from blood clotting allowed to occur clotting proteins not
present
• Plasma obtained by centrifugation
• Blood volume regulation via kidney
