淋巴的重要性 - Importance of lymph

文章导读

相信很多人都知道,人们身上有很多淋巴组织,很多人不知道你吗?这些东西到底对人们身体来说有什么样的好处或者有什么样的作用?但是一些人肯定会知道淋巴有变异成癌症的可能性,就导致人们对于态度不是太友好。那么礼貌这种东西对于人们的身体来说到底有什么样的好处呢?它对于人们来说到底有多重要呢?

一、淋巴的重要性

淋巴结是机体重要的免疫器官,是接受抗原刺激产生免疫应答反应的场所,有过滤、增殖和免疫作用。

1、人体重要防卫体系

淋巴系统是人体的重要防卫体系,它与心血管系统密切相关。淋巴系统能制造白细胞和抗体,滤出病原体,对于液体和养分在体内的分配也有重要作用。 像遍布全身的血液循环系统一样,淋巴系统也是一个网状的液体系统。淋巴系统里流通的淋巴液,由血浆变成,但比血浆清,水分较多,能从微血管壁渗入组织空间。

2、脾脏是最大的淋巴器官

脾脏是最大的淋巴器官,脾能过滤血液,除去衰老的红细胞,平时作为一个血库储备多余的血液。 淋巴系统有许多管道和淋巴结,毛细淋巴管遍布全身,收集多余的液体,输入两条总导管:一条是淋巴系统的主干胸导管,与脊柱互相平行,通向左边近心脏的一条大静脉;另一条是右淋巴导管,通向右边的静脉。 淋巴系统没有一个像心脏那样的泵来压送淋巴液。新的组织液流入细胞间的空隙中的液体挤入淋巴管。动脉和肌肉的张缩也对淋巴液施加向前的压力。呼吸作用则在胸导管内造成负压,使淋巴液向上流而回到血液中去。

3、滤出微生物和毒素

人受伤以后组织会肿胀,要靠淋巴系统来排除积聚的液体,恢复正常的液体循环。沿着毛细淋巴管有100多个淋巴结或淋巴腺,身体的颈部、腹股沟和腋窝特别密集。每个淋巴结里有一连串纤维质的瓣膜,淋巴液就从此流过,滤出微生物和毒素,并加以消灭,以阻止感染蔓延。

二、淋巴结是什么

当病毒侵入人体发生感染时,淋巴结会肿大疼痛。像喉咙发炎时,会在下巴颏下摸到两个肿块,那就是淋巴结。炎症消失后淋巴肿块也会自然缩小。 组织液进入淋巴管即成为淋巴液。淋巴液和淋巴细胞组成了通常所说的“淋巴”。

I believe many people know that people have a lot of lymphoid tissue, many people do not know you? What are the benefits or effects of these things on people's body? But some people will surely know that lymph has the possibility of mutating into cancer, which leads to people's attitude is not too friendly. So what are the benefits of politeness to people's bodies? How important is it to people?

1. The importance of lymph.

Lymph node is an important immune organ of the body. It is the place where antigen stimulation produces immune response. It has the functions of filtration, proliferation and immunity.

1, the important defense system of human body

The lymphatic system is an important defense system of the human body. It is closely related to the cardiovascular system. Lymphatic system can produce white blood cells and antibodies, filter out pathogens, and play an important role in the distribution of liquid and nutrients in the body. Like the blood circulation system that spreads all over the body, the lymphatic system is also a netted liquid system. The circulating lymph in the lymphatic system changes from plasma to serum, but it has more water than plasma, and can infiltrate tissue space from the microvascular wall.

2, the spleen is the largest lymphoid organ.

The spleen is the largest lymphatic organ. It filters blood, removes aging red blood cells and stores surplus blood as a blood bank. There are many lymphatic ducts and lymph nodes in the lymphatic system. The capillary lymphatic ducts are all over the body. They collect excess fluid and are fed into two main ducts: one is the main thoracic duct of the lymphatic system, which is parallel to the spine and leads to a great vein near the heart on the left side; the other is the right lymphatic duct, which leads to the vein on the right side. The lymphatic system does not have a pump like the heart to pressurized lymph. The new tissue fluid flows into the intercellular space of the fluid and squeezed into the lymphatic vessels. The contraction of arteries and muscles also exerts a forward pressure on lymph. Respiration causes negative pressure in the thoracic duct, causing lymph to flow upward and return to the blood.

3. Filter out microbes and toxins.

When a person is injured, the tissue will swell. It depends on the lymphatic system to remove the accumulated fluid and restore the normal fluid circulation. Along the capillary lymphatics there are more than 100 lymph nodes or lymph glands, especially in the neck, groin and axilla of the body. Each lymph node has a series of fibrous valves from which lymph flows, filters out microorganisms and toxins, and destroys them to prevent the spread of infection.

Two. What is lymph node?

When the virus invades the human body, the lymph nodes will become swollen and painful. Like throat inflammation, there are two lumps under chin: lymph nodes. After the inflammation disappeared, the lymphatic masses would also shrink naturally. Tissue fluid enters lymph vessels and becomes lymph. Lymph and lymphocytes constitute what is commonly referred to as "lymphatic".
