Introduction to Gangrene: What is Gangrene and How Can it Affect You? Gangrene is a severe and potentially fatal medical condition that arises when blood flow to a specific area of tissue is obstructed, leading to tissue decay and death. This often manifests as a greenish-black discoloration of the affected skin. Gangrene can result from a combinat
Read More主动脉的作用 主动脉是一条大血管，从心脏开始，穿过胸部和腹部，是负责将富含氧气的血液从心脏输送到身体各器官的主要动脉。 随着血液的流动，更小的血管分支向不同的组织供应血液。 主动脉壁变薄会导致隆起，当这种情况发生在腹部时，就会导致腹主动脉瘤，这是一种潜在危险的动脉扩张，需要就医以预防并发症。 (http://www.gadacanada.ca/aorta-taad) 主动脉瘤概述 动脉瘤的形成是由于动脉壁的强度降低，动脉内的压力积聚，导致动脉壁的薄弱部分突出。 这种向外凸出的现象被认定为动脉瘤。 具体来说，腹主动脉瘤（AAA）是指负责将血液从心脏输送到全身的主要血管主动脉扩张。 This artery courses through the torso, supplying blood to

Read More人体静脉的意义和功能 静脉负责将血液从各个器官输送回心脏，而动脉则将富含氧气和营养物质的血液从心脏输送到身体的各个部位。 很多静脉，尤其是手臂和腿部的静脉，都有单向阀。 这些阀门由两个边缘相接的瓣膜组成。 顺着心脏方向流动的血液会使这些瓣膜打开，就像一对只朝一个方向移动的旋转门。 如果重力或肌肉收缩试图逆转血流，或者血液试图在静脉内积聚，这些瓣膜就会自动关闭，防止血液倒流。 因此，这些瓣膜有助于血液回流到心脏，在血液流向心脏时打开，在可能出现逆流时关闭。 (https://veinscarolina.com/a-discussion-about-venous-reflux-with-vein-specialist-dr-david-draughn/) 人体深静脉及其重要作用 位于身体深处的静
Read More肾功能和透析治疗概述 在健康的身体中，肾脏起着过滤器的作用，每分钟能清洁约半杯血液。 它们排出废物和多余的水分，形成尿液。 然后，尿液通过细长的肌肉管道（膀胱两侧各一条）从肾脏进入膀胱。 膀胱会储存这些尿液，直到需要排出时才排出。 所有这些部分–肾脏、输尿管和膀胱–共同组成了您的尿路。 (https://visualsonline.cancer.gov/details.cfm?imageid=9050) 患有高血压和糖尿病等疾病会增加患肾衰竭的几率。 肾衰竭也可能来自身体损伤、疾病和其他病症等伤害性来源。 当肾脏工作不正常时，废物就会在体内堆积。 透析接手了清洁血液的工作，通过排出多余的液体和废物来保持身体平衡。 此外，它还有助于控制血压，这对人体健康非常重要。 透析
Read MoreCarotid arteries, vital vessels in your neck, supply blood to your brain and head. Carotid artery disease occurs when these arteries narrow due to plaque buildup, mainly fat, cholesterol, and calcium. This condition can lead to blockages, potentially causing strokes. While symptoms might not manifest until severe narrowing occurs, signs like a dist
Read MoreThe Importance of the Kidney The kidneys play a vital role in cleaning the blood and sending the purified blood back into the body. They filter about one liter of blood per minute, and this cleaned blood returns to circulation. Inside each kidney, there are around a million small parts called nephrons. Each nephron has a tiny filter called a glomer

These veins play a crucial role in the blood circulation of the testicles, supporting their essential functions. The testes (testicles) are located in the scrotum, which is a pouch of skin behind the penis. Similar to varicose veins observed
