Your body is a fortress that is always under attack. External foes include infectious illnesses, parasites, environmental pollutants, physical trauma, allergies, and natural catastrophes. Internally, it is endangered by overactive allergy, immunological, and inflammatory reactions, as well as cancer-causing cellular alterations.

Fortunately, the body’s defenses are extraordinarily effective, and we are usually unconscious of the dramatic drama unfolding within our cells and organs.

The fascinating nuances of this drama comprise the area of pathophysiology, which is the study of abnormalities in normal physiological functioning caused by disease or damage. Medical students are given a thorough introduction to this topic early in their training, and the greatest clinicians are experts in it. However, few laypeople grasp the tale of how our bodies fail and how they recover themselves.

The Human Body: How We Fail, How We Heal aims to bridge this knowledge gap. In 24 half-hour courses, you will learn about how the body responds to sickness and damage with astonishing defenses and healing capacities, and how, in certain situations, it may fail or overreact.

A Medical Professional Who Can Tell You What’s Wrong and Why

Dr. Anthony A. Goodman is your tour guide. He is a surgeon, educator, author, and expert presenter of medical information. In his previous course, Understanding the Human Body: An Introduction to Anatomy and Physiology, many Teaching Company students have already encountered his calming bedside approach. That series addressed the typical operation of the body’s organ systems, as well as glimpses of more prevalent clinical issues.

Dr. Goodman now offers a thorough examination of what might go wrong, why, and how the body responds, as well as what clinicians can do to intervene. There is no better example of the wonderful complexity of the human body and the everyday marvel of good health.

Hundreds of Medical Illustrations

Dr. Goodman discusses many topics that you may have wondered about, while also bringing you down intriguing roads that will be entirely new to you. Among the hundreds of instances he provides:

Grapefruit with medicine: Many pharmaceuticals cause cells to react as if they were poisons, which is why the medications only operate for a brief period of time before being ejected. Specific grapefruit compounds interfere with this “toxin-recognition” function in some cells, causing the drug to stay in the system for longer than usual—a regular dose may become excessive.
When you see an ophthalmologist for a problem like conjunctivitis, a corneal abrasion, or an infection, the doctor will ask you to close your eye and then cover the eyelid with gauze and adhesive tape to keep it closed. The inside of the eyelid is the greatest dressing in the world. It was never exceeded.
Human bite: The human oral flora is exceedingly poisonous everywhere except in the mouth. As a result, human bites are among the most harmful. If the “boxer’s fracture”—a fractured hand from a strike to the opponent’s teeth—is contaminated with bacteria from the mouth, it must be treated much more urgently than a dog or cat bite.
Appendicitis: An early pain around the appendix is more likely to be a kidney stone than appendicitis, which typically begins as pain around the navel due to how nerves interpret swelling in the intestines. Dr. Goodman shows how pain migrates when the appendix gets clogged, swollen, and infected.
Colon cancer: Most colon cancers are caused by tumors that progress from benign to malignant in a regular pattern. Polyps, which are precancerous growths, can be removed with early management. “We almost eliminate colon malignancies in the group willing to be colonoscoped every five to ten years or so,” Dr. Goodman remarks.

Learn the Terminology Used by Doctors

One of the most beneficial aspects of this training is the introduction to medical terminology. Dr. Goodman is generous in his use of technical jargon and equally generous in his explanations of them. You’ll discover the distinction between signs and symptoms, whether a sickness is acute vs chronic, how to tell the difference between endemic, epidemic, and pandemic, and why the malapropism exists. Elephantitis is an incorrect phrase that means “inflammation of your elephant.” Elephantiasis is the proper term (meaning “appearing like an elephant”).

Dr. Goodman reminds viewers that medical students are exposed to thousands of new terms in their first two years, and that physicians must comprehend one other as well as the biology of the body, which is why a precise, familiar vocabulary is essential. “We’ll try to keep these concepts in play all the time,” he adds reassuringly, “and I think you’ll find them just a part of your lexicon as we go along.”

It’s just one of the many ways Dr. Goodman treats you with collegiality while presenting you to the body’s amazing, but natural, systems of healing and self-defense when confronted with the assaults and mishaps of everyday life.

What You Will Discover

Cellular level: Following an introduction lecture that describes the scope of the course, you begin at the cellular level, investigating the function of cells and the many types of damage. This provides the groundwork for all that comes after.

The immune system and inflammation: The inflammatory response is the body’s most rudimentary and rapid response to most types of assault. The immunological response is slower but more advanced, and it is tailored to each danger, for which it creates a unique memory.

Infectious illnesses are the most persistent and lethal threats to humanity. They can be caused by a variety of factors, including molecular prions, viruses, bacteria, parasites, and worms. These lectures will concentrate on their prevention and treatment.

Shock: When the body detects a dangerous threat, it initiates an automatic, systematic shutdown of functions to protect the brain and heart. This eventually life-saving response is known as shock, and it can swiftly lead to death if appropriate precautions are not taken.

Cancer is a self-inflicted damage generated when a cell’s genetic machinery malfunctions. These lectures investigate the environmental origins of cancer, the particular phases in its molecular biology, and treatment techniques for its many types.

Wound healing: Wound healing exemplifies the complicated and amazing processes of physiological healing and restoration in infections, trauma, and surgical intervention. You might be startled to find that no wound has to be closed, and that attempting to seal a potentially infected wound is typically a terrible idea.

Dr. Goodman’s objective is to provide you with the knowledge to comprehend illnesses and injuries, as well as the body’s response to them. Such information is not a substitute for seeing your doctor; but, you will be better equipped to communicate with your doctor, know what questions to ask, and have greater clarity about your own or a loved one’s sickness.

Please keep in mind:

These lectures are designed to help students better comprehend the structure and function of the human body. They are not intended to be used as medical references for diagnosing or treating medical conditions or injuries. Neither The Teaching Company nor Dr. Goodman are liable for any outcome resulting from the usage of this material. Questions about medical diagnosis or treatment must be brought to the attention of certified medical experts.
