Blood Vessel Anatomy: Exploring the Structure of Sectional Views
The anatomy of blood vessels is a cornerstone of the circulatory system, with their sectional views revealing the intricate layers that facilitate blood transport throughout the body. This image provides a detailed look at the tunica intima, tunica media, and tunica adventitia, showcasing the structural adaptations that support the high-pressure demands of arteries and the lower-pressure needs of veins.
Blood Vessel Anatomy: A Comparative Study of Arteries and Veins
The structure of blood vessels plays a fundamental role in maintaining the body’s circulatory system, with arteries and veins showcasing distinct yet related anatomical features. This image provides a sectional and microscopic view, highlighting the thicker walls of arteries compared to veins due to the higher pressure of blood flow, as captured in a micrograph at 160x magnification, courtesy of the Regents of the University of Michigan Medical School.
Adrenal Gland Hormones: Functions and Overview
The adrenal glands, perched atop the kidneys, are vital endocrine organs that produce hormones essential for stress response, metabolism, and electrolyte balance. This article explores a detailed chart outlining the hormones secreted by the adrenal glands, their release mechanisms, and their physiological effects, offering a comprehensive look at their role in maintaining bodily homeostasis.
CURB-65 score
The CURB-65 score is a clinical prediction tool used to assess the severity of community-acquired pneumonia (CAP) in adults and guide decisions on treatment setting (outpatient, inpatient, or ICU). Developed in 2003 by Lim et al., it stratifies patients based on mortality risk using five simple criteria. The acronym stands for Confusion, Urea, Respiratory rate, Blood pressure, and age ≥65 years. CURB-65 is widely used in emergency departments, primary care, and hospital settings due to its simplicity and validated prognostic accuracy.
Circulatory system gross view (lymphatic system and blood system)
The blood circulatory system, powered by the heart, delivers oxygen and nutrients to tissues while removing carbon dioxide and metabolic waste. Meanwhile, the lymphatic system acts as a complementary drainage network, collecting excess interstitial fluid and returning it to the bloodstream while simultaneously serving as a critical component of the immune system. This integrated approach to circulation showcases the body's remarkable efficiency in maintaining homeostasis and protecting against pathogens.
