Mini Unit - Digestion (Topic 6.1) - It's all about Structure/Function
It all starts in the mouth with saliva. Saliva helps us swallow food, protects our teeth and even gives us a sense of sweetness as it converts starch to glucose. Anthropologist and evolutionary biologist Nathaniel Dominy, associate professor in the Department of Anthropology at Dartmouth College, has studied saliva from around the globe. He researches how humans acquire, process and assimilate food -- and how those behaviors affect the evolution of anatomical form and function. Listen to the following short interview.
Be able to explain why a given structure is supportive of a corresponding function! This is the basis of many of the questions on the Essential Biology packet.

Left: nice visual way to show the difference between absorption and assimilation....what is the destination?
Above: SA/vol ratio...at three levels in the small intestine.

Note how neatly digestion allows you to revisit the concepts of enzymes.

6.2 Transport (Circulation - connected to Gas exchange and Kidney functions)
HOW DO THE VALVES WORK?
valves in the heart maintain one-way flow of blood
|
valves are also found in the veins of the legs - Why??

WHAT STARTS THE SYSTEM? MYOGENIC SINO-ATRIAL NODE. NOTE WHAT IS MUSCLE AND WHAT IS NERVE TISSUE IN THE FOLLOWING (click on image to set animation)
WHAT CONTROLS THE RATE?
INCLUDE ROLES OF CARBON DIOXIDE, CHEMORECEPTORS IN THE BLOOD,
THE MEDULLA OBLONGATA IN THE BRAIN, THE VAGUS NERVE,
EPINEPHRINE, AUTONOMIC CONTROL, NEGATIVE FEEDBACK.

What's new?
6.4 - Gas Exchange
Gas exchange (a) oxygen (red) from lungs TO capillary, (b) from capillary TO body cells. Carbon dioxide (blue) is shown in the reverse path

Tissue level and cellular level diagrams of lung structure
|
Photomicrograph of lung tissue - note the interconnectedness of lung and capillary tissues
also look at the torso model in class and diagram below - note the internal and external intercostal (in between the ribs) muscles - which contracts with inspiration and which with expiration?
|
also look at lung model in class and diagram below - what happens as the diaphragm contracts?
|
external intercostals contract - expands thoracic cavity
internal intercostal contract - decreases volume in thoracic cavity
|
diaphragm contract - expand thoracic volume,
diaphragm relaxes - decrease thoracic volume

TAKE SOME TIME TO WATCH THIS FILM...Public Health Case Study
Based on Randy Shilt's 1987 book of the same name. All real characters, played by many prominent actors who volunteered their time. Excellent portrayal of the intersection of politics and science, especially the under-recognized area of public health.

A REFLECTIVE UPDATE
From the website of the same name...and available on Netflix.
2011 marks 30 years since AIDS descended. Like an unrelenting hurricane, the epidemic roiled San Francisco for two decades and only began granting some reprieve with medical advancements in the late 90s. The death years of AIDS left the City ravaged and exhausted, yet, as in most of the developed world, the worst seems past. Though thousands are still living with HIV, and new infections continue at an alarming rate, the relentless suffering of the 80s and 90s has given way to a kind of calm, and, understandably, a degree of willful forgetfulness. We Were Here utilizes San Francisco’s experience with AIDS to open up an overdue conversation both about the history of the epidemic, and the lessons to be learned from it.

11.2 MUscles and movement
FIRST, GO THROUGH THE MACROSCOPIC LEVELS OF UNDERSTANDING MUSCLES, BONES, TENDONS, LIGAMENTS, JOINTS, ETC...USE THE POWERPOINT TO REVIEW THIS AND ANSWER THE ESSENTIAL BIOLOGY QUESTIONS.
THEN SPEND A GOOD DEAL OF TIME REALLY BREAKING DOWN THE STEPS IN SLIDING FILAMENT THEORY
Clicking on the image should take to the Campbell Biology site. Try turning off the narration and see if you can explain it yourself.
HOW DARWIN CONNECTS WITH BRAVE NEW WORLD CONNECTS WITH SLIDING FILAMENT THEORY...
The animation/explanation goes by pretty quickly, but the cross-disciplinary connections are worth a look.
