Anatomy of the Circulatory System02:03

Anatomy of the Circulatory System

92.4K
The human circulatory system consists of blood, blood vessels that carry blood away from the heart, around the body, and back to the heart, and the heart itself, which acts as a central pump. The systemic circuit supplies blood to the whole body, the coronary circuit supplies blood to the heart, and the pulmonary circuit supplies blood flow between the heart and lungs.

Blood Flow01:29

Blood Flow

70.2K
Blood is pumped by the heart into the aorta, the largest artery in the body, and then into increasingly smaller arteries, arterioles, and capillaries. The velocity of blood flow decreases with increased cross-sectional blood vessel area. As blood returns to the heart through venules and veins, its velocity increases. The movement of blood is encouraged by smooth muscle in the vessel walls, the movement of skeletal muscle surrounding the vessels, and one-way valves that prevent backflow.

Overview of Systemic and Pulmonary Circulation

4.9K
The systemic and pulmonary circuits are crucial components of the circulatory system, working together to transport blood between the heart, lungs, and the rest of the body. The process begins with pulmonary circulation, where deoxygenated blood is pumped from the right ventricle to the lungs via the pulmonary trunk and arteries. Upon reaching the lungs, the blood becomes oxygenated and returns to the heart, specifically to the left atrium, via the pulmonary veins.
The oxygenated blood is sent...

Design Example: Flow of Oil Through Circular Pipes

154
Understanding fluid flow behavior through pipes is critical in fluid mechanics, especially in applications like oil transportation through pipelines. Hagen-Poiseuille's law provides an exact solution derived from the Navier-Stokes equations for steady, incompressible, and laminar flow within a circular pipe. Hagen-Poiseuille's law helps determine the necessary pressure drop across a pipeline section by determining parameters like pipe length, radius, oil viscosity, and the desired...

Overview of Pulmonary Circulation01:19

Overview of Pulmonary Circulation

1.3K
The pulmonary circulation is a vital system in our body that acts as a bridge between the respiratory and cardiovascular systems. It serves as a transport network for deoxygenated blood from the heart to the lungs and then returns oxygen-rich blood back to the heart.
The process begins with the right ventricle of the heart pumping deoxygenated blood into the pulmonary trunk. This large vessel extends about 5 centimeters before splitting into the left and right pulmonary arteries. These arteries...

Anatomy of Blood Vessels01:20

Anatomy of Blood Vessels

619
The vascular system, an integral part of the circulatory system, comprises various blood vessels that play crucial roles in maintaining the body's homeostasis. These blood vessels form a complex and efficient circulatory network. The three primary categories of blood vessels are the arteries, veins, and capillaries.
Arteries
Arteries circulate oxygenated blood from the heart, except the pulmonary artery, which transports deoxygenated blood to the lungs. Large arteries, such as the aorta,...

Summary

Scientific images are crucial for knowledge production and dissemination in life sciences. This issue explores how images circulate, focusing on their social life and the role of trust in their scientific impact.

Area of Science:

  • Life sciences
  • Scientific visualization
  • Historiography of science

Background:

  • Scientific images are integral to knowledge production and dissemination.
  • Understanding the journey of scientific images is key to appreciating their impact.
  • Existing studies often overlook the dynamic nature of scientific imagery.

Purpose of the Study:

  • To introduce 'circulation' as a framework for analyzing scientific images.
  • To explore how images are adopted, co-opted, and adapted in life sciences and beyond.
  • To connect studies on visualization in knowledge production with those on broader dissemination.

Main Methods:

  • Thematic analysis of papers within a special issue.
  • Examination of the social life of scientific representations.
Keywords:

  • Investigation of factors influencing image circulation, such as authorship, expertise, and trust.

    • Main Results:

    • Scientific images have a dynamic 'social life' shaped by their contexts and settings.
    • Authorship, expertise, and trust significantly influence the circulation and impact of scientific images.
    • The concept of circulation offers new perspectives on the historiography of scientific images.

    Conclusions:

    • Circulation provides a valuable lens for understanding the multifaceted roles of scientific images.
    • This volume prompts new questions regarding the practice of image circulation in the life sciences.
    • Recognizing image circulation enhances our understanding of scientific knowledge production and dissemination.
