Summary
Understanding lung vasculature, including pulmonary arteries and veins, is crucial. Anatomical variations, especially in upper lobes, impact diagnosis and interventional planning for vascular lung diseases.
Area of Science:
- Thoracic anatomy
- Vascular radiology
Background:
- Pulmonary and bronchial arteries supply the lungs.
- Pulmonary veins drain into the left atrium.
Purpose of the Study:
- To describe the normal and variant anatomy of lung vasculature.
- To highlight the importance of this knowledge for diagnosis and intervention.
Main Methods:
- Review of cross-sectional imaging.
- Review of angiographic images.
Main Results:
- Pulmonary arteries parallel bronchi, with variations in upper lobes.
- Pulmonary veins run in interlobular septa, converging to form major vessels.
- Anatomical variations are common, particularly in accessory arteries.
Conclusions:
- Accurate diagnosis of pulmonary vascular pathology requires knowledge of normal and variant anatomy.
- Understanding lung vasculature is essential for planning interventional procedures.

01:27Anatomy of the Heart
120.0K
The human heart is made up of three layers of tissue that are surrounded by the pericardium, a membrane that protects and confines the heart. The outermost layer, closest to the pericardium, is the epicardium. The pericardial cavity separates the pericardium from the epicardium. Beneath the epicardium is the myocardium, the middle layer, and the endocardium, the innermost layer. There are four chambers of the heart: the right atrium, the right ventricle, the left atrium, and the left ventricle.

02:03Anatomy of the Circulatory System
98.1K
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.

02:30Histone Variants at the Centromere
5.1K
Histone variants are the histone proteins with structural and sequence variations. These variants may be regarded as “mutant” forms that replace their canonical histone counterparts in the nucleosomes. Specific post-translational modifications on the histone variants enable further chromatin complexity and regulate tissue-specific gene expression. The most common histone variants are from histone H2A, H2B, and linker histone H1 families. However, several variants of histone H3...

01:11Anatomical Positions
20.4K
In anatomy, several standard anatomical positions are used as references for describing the position and orientation of different body parts. These positions help provide a common frame of reference when discussing anatomical structures. The anatomical position is the standard reference point for describing the body's position and orientation. In this position:
The body is upright, facing forward, and standing erect.
The feet are parallel and flat on the floor.
The arms are hanging by the...

01:20Anatomical Terminology
27.4K
Knowledge of anatomy is essential to understand human biology and medicine. Anatomists and health care professionals use standard terminology to describe the human body with more precision and no ambiguity. Anatomical terms have mostly Greek and Latin-derived roots. Because these languages are rarely used in conversation, the meaning of words remains the same. Each term is made up of a root in between the prefixes and suffixes. The root of a term often refers to an organ, tissue, or condition,...

00:51Anatomical Movements
16.1K
Anatomical movements refer to the various actions or motions that can be performed by the body's joints and muscles. These movements are described using specific terms to provide a standardized way of discussing and understanding the range of motion at different joints.
Here are some common anatomical movements:
Flexion and extension motions are in the sagittal (anterior–posterior) plane of motion. These movements take place at the shoulder, hip, elbow, knee, wrist,...
