The heart is practically immune to getting cancer. 2 in 100,000 of those who have cancer are those with a primary cancer of the heart. That is an astonishing low number. So, what is so special about the heart that it rarely, if ever,...

Let's dive into the cardiac action potential and how it results in the contraction of the heart. We'll talk about the signal that starts at the SA node and spreads throughout the heart. We'll also get into the phases of depolarization,...

Unlock the mysteries of the human heart with this comprehensive and easy-to-understand tutorial on EKG interpretation! We'll break down the basics of electrocardiogram analysis and help you master reading EKGs in no time. Whether you're...

Exercise Physiology | Variation of Fuel Source with Exercise Intensity

In this video, the speaker discusses the anatomy and injuries related to the calf muscles and the Achilles tendon. They explore the relationship between calf strains, Achilles tendonitis, and Achilles tendon tears, using examples from...

This video explains the concept of cell specialization and differentiation. The narrator discusses how cells differentiate to become specialized for their unique functions within an organism. The differences in differentiation between...

In this video, we will explore the physiological events in the cardiomyocyte that occur during the cardiac action potential. What occurs during each phase of the action potential?<br/>

In this video, we take a look at the graph representing the cardiomyocyte action potential and what each region of the graph represents.<br/>

Creatine Physiology, Biosynthesis, and Organic Mechanism (Part 1) Gly Amidinotransferase; GANMT

It explains the significance of tissues in living beings and lists different types of plant and animal tissues.

The video discusses how the organs in the digestive system work together to break down food molecules into smaller and soluble molecules that can be absorbed by the body. The example of muscle tissue is used to illustrate how a large...

The video discusses the importance of glucose in the human body and how blood glucose concentration is monitored and controlled through the release of insulin by the pancreas. The video explains how insulin helps lower blood glucose...

In this lecture, I discuss the endocrine system and how endocrine glands control functions in the body through the release of hormones. The pituitary gland is known as the Master Endocrine Gland and plays a major role in controlling the...

Making Biology Fun. In this video, I go through the P wave, QRS complex, T and U waves of the Electrocardiagram and go into the details of what each of them represents. Enjoy!

In this episode, I start talking about skeletal muscle contraction, by giving a general introduction into how muscle contraction happens. I deal with how the action of actin and myosin in the sarcomere results in movement. Enjoy!

In this episode, I show how the Action potential is generated in cardiac muscle cells and how this results in Contraction of the Heart. When the action potential happens, calcium ions are released from the Sarcoplasmic reticulum, causing...

Have you ever wondered what creatine is and how it works, then this video is for you. I'll explain the biology behind creatine in the context of how muscle contraction happens. Enjoy!

It explains the occurrence, location, reactions, enzymes involved, products formed and energy balance sheet

This video discusses how muscles respond and adapt to exercise. It explains the differences between slow twitch and fast twitch muscle fibers and how they adapt differently to exercise. The video also discusses the importance of...

Biology is all about cells and living organisms. But after the summer holidays, Sally can’t remember what a cell is! Why is she uploading photos on Instagram when she has an exam tomorrow? Thankfully, it’s not difficult to learn about...

This live-action video program is about muscle types. The program is designed to reinforce and support a student's comprehension and retention of the term through use of video footage, photographs, diagrams and colorful, animated...

This video explains the process of cellular respiration and the different ways in which respiration can take place. It discusses aerobic and anaerobic respiration, along with their word equations and balanced symbol equations. The video...
