Organ Systems
Organ Systems Objective
- Provide examples of different organ systems, including the hierarchy of organ system, organ(s), tissues, and cells.
Instead of a final exam, you will be constructing a final portfolio of your work. This includes your weekly media pieces and quiz responses.
The easiest way to do this is to add your favorite media pieces and quiz responses to your portfolio as the course progresses instead of waiting until week #10. So to get started, the next two videos introduce the portfolio.
This video provides an overview of the portfolio, including how to use the course outcomes.
Examine the course learning outcomes in more detail
This video provides ideas about different possible portfolio formats.
The sky is the limit! For example, you could do an entire slide show about your own body, a “natural history of you.” Or you could provide different observations about humans in a journal about our species. As long as you substantially address the nine course learning outcomes, you have room for creativity.
Are you thinking of featuring COVID-19 in your portfolio?
We shot this video in the spring of 2020 when Covid-19 started weighing heavily in our minds.
Organ Systems
One of the earliest things we learn about the human body is that we have different organ systems made up of organs. For example, the urinary system has kidneys and a bladder; the cardiovascular system includes the heart and blood vessels, and the skeletal system is made up of bones.
Organ systems are made up of organs, and many of those organs are generally familiar. What is less familiar is that organs are made up of tissues, and tissues are groups of cells.
The integumentary system we covered in the last module was pretty straight forward, an organ system with one basic organs (skin) and it’s appendages (hair and nails). The skin organ is made of tissues: epithelial in the epidermis, loose connective in the dermis, and adipose connective in the hypodermis. We also met some of the cells in the tissues: keratinocytes in the epithelial tissue of the epidermis, fibroblasts in the connective tissue of the dermis, and adipocytes in the connective tissue of the hypodermis.

This week we start building off of the basics you learned last week. For example, we will be back to skin when we discuss the impacts of aging on organs.
Check your memory of skin basics with this video.
This week’s two organ systems are also straight forward. This video explains why.
This video uses an inexpensive flip chart to provide an overview of the organ systems we are covering in the weeks to come.
The next section provides an overview of the skeletal system, followed by a detailed look at the bone organs, bone connective tissue, and bone cells.
Check your knowledge. Can you:
