Types of Capillaries: Understanding Continuous, Fenestrated, and Sinusoid Structures

Cardiovascular System anatomy-note-512-512-png-1-96x96 Tag Template - Week PRO Anatomy Note -
Capillaries are the smallest blood vessels in the body, playing a crucial role in the exchange of nutrients, gases, and waste products between blood and tissues. This diagram illustrates the three major types—continuous, fenestrated, and sinusoid—highlighting their unique structural features that determine permeability and function in various organs.

Red Blood Cell Maturation: The Process of Nucleus Extrusion in Erythroblasts

Physiology anatomy-note-512-512-png-1-96x96 Tag Template - Week PRO Anatomy Note -
The red blood cell maturation process involves a critical transformation where erythroblasts extrude their nucleus to become mature, hemoglobin-rich cells. This article examines a micrograph showcasing this process in two panels, one before and one after nucleus ejection, highlighting the structural changes that enable red blood cells to efficiently transport oxygen. Sourced from the Regents of University of Michigan Medical School, the images provide a detailed look at this essential stage of erythropoiesis.

Cardiovascular system: artery and vein diagram

The cardiovascular system represents a complex network of blood vessels that transport essential nutrients, oxygen, and waste products throughout the body. This detailed illustration demonstrates the hierarchy of blood vessels, from major arteries and veins to microscopic capillaries, showing how blood circulates from the heart to tissues and back. The diagram uses color coding to distinguish between oxygen-rich (red) and oxygen-poor (blue) blood vessels.
