The Body's Systems I
Reading
OpenStax book: Ch. 16 "The Body's Systems", sections 16.1 through 16.3
BJU: 21A - "The respiratory system", 21B - "The digestive system, and 22A - "The circulatory system"
AP students planning to take the AP exam May 14th need to be reviewing the Princeton study guide
Topics
Labs
Memo: 2020-2021 labs will include hands-on and virtual, and may vary as the Covid-19 situation changes.
Here is a list of possible labs for this lesson. I will choose from this list when we get here.

Here is a list of possible labs for this lesson. I will choose from this list when we get here.
- Cow eye dissection
- Sheep heart dissection
- Kidney dissection
- Virtual heart surgery
- Or... we could spend another week finishing one of the "Biotechnology labs" from the previous 3 Units
- And... there are many virtual labs on physiology and infectious disease
Lecture outline
This section of Biology, called "Body Systems", examines the structure, layout, and function of human tissues, organs, and systems.
Levels of structure:
This section of Biology, called "Body Systems", examines the structure, layout, and function of human tissues, organs, and systems.
Levels of structure:
- Atoms bond together to form molecules
- Molecules assemble to form cells (you have trillions of cells in your body)
- Similar-functioning cells group together to form tissues (you have about 200 different tissues in your body)
- Tissues group together to form organs (heart, lungs, pancreas)
- Organs function together as organ systems (the heart, blood, and blood vessels make up the circulatory system)
- Organ systems make up the organism (humans, fruit flies, seaweed, dolphins
Video clips below: we will watch and discuss these in class

LABS & HOMEWORK BELOW: There are numerous labs, projects, presentations, and homework exercises posted on this portal. Don't panic. Some of these are current, some are left over from prior years, and some are just "parked" here for future use. DO NOT WORK ON A LAB OR HOMEWORK EXERCISE unless it has been assigned in your weekly class email! Due to the 2020-2021 Covid-19 situation, I will assign labs and homework as we go along based on what we are able to do.

Digestive System Review Questions
Read BJU "Digestive System" (posted above) and answer Review Questions 21.4 (12 questions) and 21.5 (7 questions). Give complete, well thought-out answers. Number your answers the same way the book has them numbered. Turn in your completed work as an email attachment.

2019 Digestive System lab
We test the "digestion" of various foods in hydrochloric acid (to simulate the stomach) and a variety of enzymes (to simulate the small intestine), observe and compare the results.
