This Khan Academy video describes how the proteins myosin and actin interact to produce a mechanical force on muscles, allowing them to move.

Type: Tutorial

This Khan Academy video explains the role that tropomyosin and tropinin play in muscle contraction. The role of the calcium ion concentrations are also explained.

This challenging tutorial addresses the concept at a high level of complexity.

Type: Tutorial

This Khan Academy video describes the structure of muscle cells. The tutorial details the muscle cell from the macro skeletal muscle to the individual cell of the muscle, called the myofiber. The functions of actin and myosin and how they cause muscles to contract are also explained.

This tutorial will help you to understand how bone growth is different from the growth of many other organs. Although bone may appear to be rigid and lifeless it is actually living tissue that is capable of growth. Unlike soft tissues, bone cannot simply grow by adding additional cells and removing cells that are no longer necessary. The calcium laid down in bone gives the skeleton the strength and rigidity needed to protect and support the body. This rigidity means that expansion requires addition of cells on the outside and, when necessary, the removal of calcium and other materials on the inside.

This tutorial helps you to understand the factors involved in air flow into and out of the lungs.

This challenging tutorial addresses the concept at a high level of complexity.

This tutorial explains that electrical signals cannot travel from one neuron to the next directly. The signal crosses the synapse in chemical form. One neuron releases chemicals in response to an action potential and the chemicals travel across the synapse and stimulate an action potential in the next neuron. These chemicals are called neurotransmitters.

Type: Tutorial

This tutorial explains the exchange of oxygen and carbon dioxide within the respiratory system.

Type: Tutorial

This tutorial will help you to understand how the exchange of gases between the alveoli and the blood occurs by simple diffusion due to the changes in the partial pressure of oxygen and carbon dioxide.

This challenging tutorial addresses the concept at a high level of complexity.

Type: Tutorial

This tutorial is helpful in understanding how the exchange of oxygen and carbon dioxide takes place during the process of respiration.

Type: Tutorial

This tutorial will help you to visualize and understand how nerve impulses cause muscle contractions. The neurons and muscle tissue conduct electrical current by moving ions across cellular membranes. The signal will travel through the tissue and trigger the contraction of individual sarcomeres, the functional units of muscle. This tutorial explains the neuromuscular junction where the synapse occurs.

Type: Tutorial

This tutorial will help you to understand which factors determine the strength of bone. Bone strength is determined by the internal structure, shape, and size of the bone. As we age, bone mass is lost, leading to a common condition called osteoporosis. This tutorial compares normal bone tissue with osteoporotic bone tissue.

Type: Tutorial

This tutorial will help you to understand how the movement of oxygen and carbon dioxide takes place between the alveoli and the blood by taking partial pressure into consideration. Oxygen diffuses from the air through the alveoli into the blood and carbon dioxide diffuses from the blood into the alveoli. This occurs due to differences in partial pressures.

This challenging tutorial addresses the concept at a high level of complexity.

This tutorial will help you to understand how all of the components of the heart are able to work together without direct control from the central nervous system. This video shows that for proper function of the heartbeat, it is necessary that all of the muscle fibers in a region contract in unison.

Type: Tutorial

This tutorial will help students understand the process of muscle contraction. A muscle contains many muscle fibers and each fiber contains a bundle of 4-20 myofibrils. Each fibril is striated and these striations are produced by the arrangement of thick and thin filaments, called actin and myosin. The contraction and relaxation of these actin and myosin filaments help muscles move.

Blood pressure is determined by the force of the blood acting on the walls of the blood vessels. Two factors determine the size of this force. One is the volume of blood being pumped through the vessel. The other is the size of the vessels. Changes in blood pressure can be caused by either a change in the amount of blood being pumped or by a change in the size of the blood vessels. Feedback mechanisms, described in this animation, will alter heart rate and blood vessel dilation to maintain blood pressure at appropriate levels.

Type: Tutorial

This tutorial will help students to understand how concentrations of gases in the blood change during breathing. This animation shows high carbon dioxide concentrations and low oxygen concentrations indicating that gas exchage is occurring at a slower than ideal rate. Because of this, heart rate increases or decreases to compensate the exchange of gas.

Type: Tutorial

This tutorial will help students understand how the difference in the alveloar pressure and the barometric air pressure allows the inspiration and expiration of air in the lungs.

This TED ED original lesson takes a closer look at how the heart pumps blood. For most of history, scientists weren't quite sure why our hearts were beating or even what purpose they served. Eventually, we realized that these thumping organs serve the vital task of pumping clean blood throughout the body. But how? Edmond Hui investigates how it all works by taking a closer look at the heart's highly efficient ventricle system.

In this animated video from TEDed, you will learn about the power of metaphors in your reading and in your writing. The video explores questions like: "How do metaphors help us better understand the world?", as well as "What makes a good metaphor?"

This video presentation will help to understand the regeneration process in a zebrafish. When the zebrafish heart is damaged, the wound site is rapidly sealed with a fibrin clot that stems bleeding within seconds. Following clot formation, the tissue that surrounds the heart muscle, the epicardium, gradually covers the fibrin clot via migration and cell division. Over the next few months, new cardiac muscle is produced and replaces the clot.

In this online activity, students burn a simulated forest and adjust the probability that the fire spreads from one tree to the other. This simulation also records data for each trial including the burn probability, where the fire started, the percent of trees burned, and how long the fire lasted. This activity allows students to explore the idea of chaos in a simulation of a realistic scenario. Supplemental materials, including background information about the topics covered, a description of how to use the application, and exploration questions for use with the java applet are linked to the applet.

In this activity, students select one of three doors in an attempt to find a prize that is hidden behind one of them. After their first selection, one of the doors that doesn't have the prize behind it is revealed and the student has to decide whether to switch to the one remaining door or stay on the door of their first choice. This situation, referred to as the Monty Hall problem, was made famous on the show "Let's Make A Deal" with host Monty Hall. This activity allows students to explore the idea of conditional probability as well as unexpected probability. This activity includes supplemental materials, including background information about the topics covered, a description of how to use the application, and exploration questions for use with the java applet.
