Mon-Day 2
Bio 3/6 - we discussed the THREE "regions" of the human circulatory system:
PULMONARY, SYSTEMIC, and CORONARY circulation.
Pulmonary circulation allows for the exchange of gases between the blood in the capillaries around the lung air sacs ("alveoli") and the air sacs themselves; carbon dioxide diffuses out of the blood and into the air sacs to be exhaled while oxygen that was inhaled diffuses from the air sacs into the blood.
Systemic circulation allows for the diffusion of the transported oxygen from the blood in the capillaries to any given body cell (nerve, muscle, hair follicle, liver) while carbon dioxide diffuses from any given body cell into the blood in the capillaries.
Coronary circulation is the transport of oxygenated blood FROM the HEART back TO the HEART, which has a constant and high demand for oxygen so that it can perform AEROBIC respiration to produce the ATP that provides the ENERGY for heart muscle contractions 24/7 (heartbeats).
AP Chem - we took the test that is the culmination and synthesis of the units on atomic structure, periodicity, bonding, molecular geometry, and finally intermolecular attractions. If you got anything wrong on this test, MAKE SURE to ask about it and go over it with me at extra help. You CANNOT do well on the AP exam without confident and accurate knowledge of the aforementioned topics.
We continue with our second semester tomorrow as we delve further into KINETICS.
Check Blackboard for the current notes on that unit.
