This page provides a detailed diagram of the heart, illustrating its various components and their functions. The diagram clearly shows the four chambers of the heart: the right and left atria, and the right and left ventricles.
Valves play a crucial role in the heart's function. They are strategically placed to prevent blood from flowing in the wrong direction, ensuring efficient circulation. The function of valves and pacemakers in heart contraction is essential for maintaining a healthy cardiovascular system.
The heart's contraction process is initiated by the natural pacemaker located in the right atrium. This pacemaker sends electrical impulses that spread through the muscular walls of the heart, causing it to contract. In cases where the natural pacemaker doesn't function properly, artificial pacemakers can be used. These devices are placed under the skin of the heart and use a wire to send electrical currents, stimulating muscle contractions.
Definition: Pacemaker - A group of cells in the heart that generates electrical impulses to control heart rate and rhythm.
Example: An artificial pacemaker is a small electronic device implanted in the chest to help control the heart's rhythm, especially when the heart's natural pacemaker is not working properly.
This page addresses common misconceptions about blood vessels and provides detailed information about arteries and veins. It's important to understand the difference between veins and arteries in the heart and their respective functions.
Contrary to popular belief, the oxygenation status of blood is not what defines arteries and veins. Instead:
The heart itself requires a supply of oxygenated blood, which is provided by coronary arteries that wrap around the heart.
A summary of the blood flow through the heart and body is provided, illustrating the complex journey of blood from body tissues, through the heart chambers, to the lungs, and back to the body.
The structure of blood vessels is also explained:
Highlight: The difference between veins and arteries in the heart is primarily based on the direction of blood flow, not the oxygenation status of the blood they carry.
Vocabulary: Lumen - The inner space or cavity of a tubular structure, such as a blood vessel, through which blood flows.
This page focuses on capillaries, the smallest blood vessels in the body, and their crucial role in the circulatory system. Capillaries form the link between arteries and veins, allowing for the exchange of substances between blood and body tissues.
Key features of capillaries include:
The thin walls of capillaries are crucial for their function, as they allow for rapid and efficient exchange of substances between the blood and surrounding tissues. This exchange is vital for maintaining the health and function of all body cells.
Definition: Diffusion - The movement of molecules from an area of high concentration to an area of low concentration, which occurs naturally without any energy input.
Highlight: The structure of capillaries, with their one-cell-thick walls, is perfectly adapted for their function of substance exchange in the heart blood flow process in circulatory system.
This final page provides practical application of the knowledge about blood flow through an example calculation. Understanding blood flow rates is crucial for assessing cardiovascular health and function.
The page presents a problem: calculating the rate of blood flow through an artery given a specific volume of blood over a certain time period. The example shows that 1464 ml of blood passed through an artery in 4.5 minutes.
To calculate the rate of blood flow:
This calculation demonstrates how to determine the rate of blood flow through a blood vessel, which is an important metric in understanding cardiovascular health and efficiency.
Example: If 1464 ml of blood passes through an artery in 4.5 minutes, the rate of blood flow is 325 ml/min.
Highlight: Understanding blood flow rates is crucial for assessing the efficiency of the heart blood flow process in circulatory system and overall cardiovascular health.
The heart is a crucial organ in the circulatory system, working alongside blood and blood vessels to maintain life. This page introduces the concept of a double circulatory system, which separates oxygenated and deoxygenated blood flow to and from the heart.
The heart's structure consists of four chambers: two atria and two ventricles. These chambers are equipped with valves that play a vital role in the heart blood flow process in circulatory system by preventing blood from flowing in the opposite direction.
The blood flow process in the heart follows a specific path:
This cycle continuously repeats, ensuring a constant supply of oxygenated blood to the body.
Vocabulary: Atria - The upper chambers of the heart that receive blood from the body and lungs.
Vocabulary: Ventricles - The lower chambers of the heart that pump blood to the lungs and body.
Highlight: The function of valves and pacemakers in heart contraction is crucial for maintaining proper blood flow and rhythm in the heart.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

Just amazing. Let's me revise 10x better, this app is a quick 10/10. I highly recommend it to anyone. I can watch and search for notes. I can save them in the subject folder. I can revise it any time when I come back. If you haven't tried this app, you're really missing out.

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.
