On January 21st, 2020, the New York Times published this article:
The article didnât even call the disease âCOVID-19â or âcoronavirusâ. Instead, the author just referred to the disease as a âmysterious respiratory infectionâ.
Thatâs because most people didnât even know about the virus. We just knew what it did to our body.
Specifically, the first case of COVID-19 in the U.S. was by an anonymous man who lived near Seattle, Washington.
We donât know who this mysterious person is, but for this article, letâs make the false claim that the first COVID patient in the U.S. was ScioVirtual Physics Instructor, Arvyn De (see picture on right).
Arvyn recently travelled from Wuhan, China back to house in Washington. However, when he came back, he was:
- Coughing
- Had a fever
- Began vomiting
Clearly, the virus is hurting his body by preventing it from functioning normally. Specifically, the virus is negatively affecting the normal anatomy and physiology of Arvyn.
Anatomy & Physiology (A&P) is simply the study of your body systems (e.g. respiratory, digestive, immune, nervous, cardiovascular etc.).
Here are the steps to learn the basics of Anatomy & Physiology.
Step 1: Understand the Basic Principles
Principle 0: Anatomy or Physiology?
We often group âAnatomyâ and âPhysiologyâ together. However, they are very different.
On one hand, anatomy is the structure of the body. For instance, if you dissect a rat and look at its internal organs, you are studying its anatomy. Another example is âneuroanatomyâ, which is the study of the parts of the brain. Learning anatomy primarily tests your ability to memorize structures and sometimes your spatial reasoning.
On the other hand, physiology is more complicated than just knowing names and locations. Physiology is the actual processes executed by organ structures. You often canât learn much physiology just through dissecting a body. Rather, physiology usually involves microscopic cellular and tissue processes such as the transmission of electric signals between neurons in the brain.
Principle 1: Cells â Tissues â Organs â Organ Systems
The body is made up of cells that make up tissues that make organs that then make organ systems. Read the Khan Academy article linked below to get an in-depth understanding of what makes anatomical structures.
Principle 2: Body Organs Promote Homeostasis
One way to think of the function of our body systems is simply to maintain homeostasis, the bodyâs inclination towards maintaining stable health conditions to keep us alive.
In light of âLearning hack #1â, I will provide three articles in increasing difficulty and length. Choose the one that feels âjust rightâ to you. You can also try to build up to the harder resource by going through them in order. Click the arrow to reveal the resource.
The importance of synthesizing knowledge
Anatomy & Physiology can get dense with information from over ten different body systems.
How do you keep track of all this information? How do you not forget everything?
The solution is: always remember the bigger picture.
âWe have a bunch of body systems, and theyâre all interdependent.â
Whisper that quote to yourself every time before you sleep. Tattoo it on your arm.
Take any component of your body and you will find that it relates to almost everything else directly or indirectly.
For a good example of the synthesis that you should be doing after you read a new section, attempt the question below before viewing the answer (by clicking the arrow).
Step 2: Applying the Principles
The more fun part about A&P is to now apply general A&P principles to specific body systems and health conditions.
Letâs go back to Arvyn and his coughing.
Medical researchers investigated why patients like Arvyn were coughing when they got the âcorona.â
What they found was interestingâŚ
- The virus enters through the nose or mouth of the victim.
- The virus invade the epithelial cells that line the airway.
- The invasion causes localized inflammation.
- This inflammation results in the death of cells through a process called pyroptosis.
The inflammation irritates Arvynâs airway, resulting him in coughing.
How does COVID-19âs mechanism of infecting Arvyn demonstrate the A&P principles above?
Now You Are Ready to Learn the Specifics
If you just want a general sense of Anatomy principles, skip this step.
Now that you have learned the basics of A&P, you can apply these principles to understand specific body systems. Select a body system that fascinates you below to explore more.
You can get extremely deep into some of these topics. For instance, here is a public Anatomy & Physiology cheat sheet for the muscular, skeletal, and integumentary systems to the right.
Donât be too intimidated at first. Most of the content will make sense after a few weeks of getting familiar to the body systems!
