Overview of Systemic Arteries01:11

Overview of Systemic Arteries

1.1K
The human body is a complex, well-organized machine, and at the heart of its operations lies the circulatory system. This network of blood vessels, which includes systemic arteries, plays a vital role in maintaining life by transporting nutrients, oxygen, and waste products to and from cells throughout the body.
Systemic circulation is the part of the cardiovascular system that carries oxygenated blood away from the heart to the body's tissues and returns deoxygenated blood back to the...

Overview of the Vascular System

3.1K
The vascular system comprises an extensive network of arteries, capillaries, and veins. The vascular system can be broadly divided into the blood and lymphatic systems. Typically, blood vessels can be categorized into three histological regions: tunica intima, tunica media, and tunica adventitia. The tunica intima consists of a single layer of endothelial cells attached to the basal lamina. Underlying the basal lamina is a connective tissue layer and an elastic lamina that gives stability and...

Nephrotic Syndrome I : Introduction

91
Nephrotic Syndrome is a chronic kidney disorder defined by clinical findings such as severe proteinuria, hypoalbuminemia, hyperlipidemia, and edema. These symptoms result from damage to the glomeruli, the kidney’s filtering units, increasing their permeability to proteins.Definition and Meaning:Proteinuria, defined as the loss of more than 3.5 grams of protein per day in adults, is a crucial feature of nephrotic syndrome. This condition is often accompanied by edema, the accumulation of...

Overview of Systemic Veins

765
Systemic veins are crucial blood vessels that return deoxygenated blood from various body tissues back to the heart. There are three systemic veins that return deoxygenated blood to the heart, they are as follows.
The coronary sinus, the heart's principal vein, resides in the coronary sulcus on the heart's posterior aspect. This broad venous channel receives nearly all venous blood from the myocardium, the heart muscle. It is fed by three primary veins: the great cardiac vein, the...

Overview of Blood Vessels

6.8K
The human cardiovascular system comprises five primary types of blood vessels: arteries, arterioles, veins, venules, and capillaries, each serving unique functions.
Arteries and Arterioles: Arteries are muscular and elastic vessels that primarily carry oxygenated blood from the heart to body tissues, except for the pulmonary artery, which carries deoxygenated blood. They have thick walls to withstand high pressure and contain a layer of muscle tissue, allowing them to expand or contract as...

Overview of Systemic and Pulmonary Circulation01:15

Overview of Systemic and Pulmonary Circulation

6.3K
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...

Area of Science:

  • Rheumatology
  • Immunology
  • Internal Medicine

Background:

  • Lupus vasculitis (LV) is a common complication in systemic lupus erythematosus (SLE), affecting approximately 50% of patients.
  • LV primarily involves small and medium-sized vessels, with rare instances of large vessel involvement.
  • Clinical manifestations vary widely based on vessel size and affected organ systems.

Purpose of the Study:

  • To provide a comprehensive overview of lupus vasculitis.
  • To describe the clinical impact and diverse manifestations of LV.
  • To focus on current treatment strategies for LV.

Main Methods:

  • This study is a review of existing literature on lupus vasculitis.
  • It synthesizes information on the pathophysiology, clinical presentation, and treatment of LV.
  • The review focuses on understanding the spectrum of LV and its management.

Main Results:

  • LV presents a broad spectrum of disease, from mild cases to life-threatening multi-organ involvement.
  • Severe manifestations include mesenteric vasculitis, pulmonary hemorrhage, and mononeuritis multiplex.
  • Prognosis is often poor, underscoring the need for timely diagnosis and intervention.

Conclusions:

  • Lupus vasculitis requires prompt diagnosis due to its potential for severe and life-threatening complications.
  • Treatment strategies for LV are dependent on the specific organs involved and the severity of the vasculitic process.
  • Effective management of LV is essential for improving patient outcomes in SLE.
