Paul Andersen introduces Anatomy and Physiology in this podcast. He starts by describing how the form of an object fits the function. He then explains the themes of homeostasis and hierarchy. He describes the four major types of tissues; epithelial, muscle, nervous and connective. [11:25]
Paul Andersen explains how hugs between tissues can help maintain homeostasis. Countercurrent heat exchange allows heat to stay within the core of the body. Close contacts between the capillaries and alveoli allow our body to maintain the correct concentration of oxygen. Capillaries also hug the tubules in the nephron to maintain osmolarity and filter the blood. [8:34]
In this video segment adapted from A Science Odyssey, learn about bubonic plague and how city officials in San Francisco tried to contain its spread in the early 1900s. [5:06]

This video describes the role of the brain in regulating body temperature and how sometimes fever is employed to fight off infection.

Students learn about the form and function of the human heart through lecture, research and dissection. They brainstorm ideas that pertain to various heart conditions and organize these ideas into categories that help them research possible solutions. An expert in the field of cardiac valve research was interviewed for this lesson and shares his ideas with the class. Students conclude by researching various possible heart defects.
A complete, self-paced lesson on homeostasis in the human body, focusing on kidney function. Students work their way through illustrated and animated tutorials, and answer review questions along the way. There is a self-checking quiz at the end of the lesson.
This lesson will explain the process of homeostasis and how it allows organisms to maintain a stable internal environment. It is 3 of 10 in the series titled "Homeostasis."
Students learn how the human body self-regulates to maintain a stable internal environment despite changes in the external environment.
This interactive simulation of human homeostasis provides students the opportunity to explore how our body maintains a stable internal environment in spite of of the outside conditions, within certain limits. This simulation allows students to investigate a phenomenon that may in real life, be dangerous to humans. Students are asked to regulate the internal body temperature of an individual using clothing, exercise, and perspiration. A four- page exploration sheet guides students through the simulation, including a short prior knowledge piece providing information on how to use the simulation and introductory questions. Two separate activities are included: one that helps students understand the how each external factor affects initial body temperature and another that allows students to explore effects on body temperature after one hour. In the second portion of the interactive simulation students try to maintain a stable body temperature when the factors are changed. Students choose the factors of exercise level, sweat level, body position, clothing, and nutrients in terms of both water and food to maintain homeostasis. The simulation generates data tables and graphing during specific time intervals of outside temperature and body temperature. Students may also alter the outside temperature as part of the simulation. Students adjust the exercise level, amount of clothing, and sweating levels. Water level, sugar level, and fatigue level are influenced by the students choices and are illustrated by bar graphs and line graphs. This simulation can provide an introduction to a lesson or unit that explores how body systems interact. This simulation provides a good foundation for continued study of how the body systems interact and would be an excellent starting point for a lesson or unit on this concept. This interactive simulation provides students with a strong introduction to how body systems interact as the simulation illustrates how to maintain body temperature, sugar level and fatigue level and students are made aware of the consequences of not maintaining those levels. The importance of water and food are also emphasized. Students can rerun the simulation making different choices to determine the effects on homeostasis. Student exploration sheets provide guides for different runs with students setting their own parameters for the runs and drawing conclusions from the resulting changes. Teachers can view student assessment responses by assigning the simulation to a class created within the ExploreLearning site. Access to the teachers guide is provided with the free 30 day access and is helpful and complete. Vocabulary of dehydration, heat stroke, homeostasis, hypothermia, and involuntary, voluntary and thermoregulation are explained in detail in the accompanying teachers vocabulary guide.
Using ordinary household materials, student “biomedical engineering” teams design prototype models that demonstrate semipermeability under the hypothetical scenario that they are creating a teaching tool for medical students. Working within material constraints, each model consists of two layers of a medium separated by material acting as the membrane. The competing groups must each demonstrate how water (or another substance) passes through the first layer of the medium, through the membrane, and into the second layer of the medium. After a few test/evaluate/redesign cycles, teams present their best prototypes to the rest of the class. Then student teams collaborate as a class to create one optimal design that reflects what they learned from the group design successes and failures. A pre/post-quiz, worksheet and rubric are provided.

Cells are found in all different types of environments, and these environments are constantly changing. For example, one-celled organisms, like bacteria, can be found on your skin, in the ground, or in all different types of water. Therefore, cells need a way to protect themselves. This job is done by the cell membrane, which is also known as the plasma membrane. Learn more about cell transport in this learning module produced by CK-12.

How do you define a living thing? What do mushrooms, daisies, cats, and bacteria have in common? All of these are living things, or organisms. It might seem hard to think of similarities among such different organisms, but they actually have many properties in common. Living organisms are similar to each other because all organisms evolved from the same common ancestor that lived billions of years ago.

Students learn about the form and function of the human heart through the dissection of sheep hearts. They learn about the different parts of the heart and are able to identify the anatomical structures and compare them to the all of the structural components of the human heart they learned about in the associated lesson, Heart to Heart.
Psychology is designed to meet scope and sequence requirements for the single-semester introduction to psychology course. The book offers a comprehensive treatment of core concepts, grounded in both classic studies and current and emerging research. The text also includes coverage of the DSM-5 in examinations of psychological disorders. Psychology incorporates discussions that reflect the diversity within the discipline, as well as the diversity of cultures and communities across the globe.Senior Contributing AuthorsRose M.
