The venules carry deoxygenated blood from the capillaries back towards the heart.
静脉毛细血管将含氧量较低的血液从毛细血管回流至心脏。
Venules are small blood vessels that join together to form veins.
静脉毛细血管是汇合成静脉的小型血管。
Inflammation can cause the walls of the venules to become leaky, allowing fluid and immune cells to enter surrounding tissues.
炎症可能导致静脉毛细血管壁通透性增加，使得液体和免疫细胞进入周围组织。
The exchange of nutrients and waste products between the blood and tissue occurs primarily through the walls of the venules.
血液与组织间营养物质和废物的交换主要通过静脉毛细血管壁进行。
As blood flows through venules, its pressure decreases due to the widening of the circulatory path.
当血液流经静脉毛细血管时，由于循环路径变宽，其压力会下降。
Venules have thinner walls than arteries because they operate under lower pressure.
静脉毛细血管的壁比动脉薄，因为它们在较低的压力下运作。
The white blood cells that fight infection often first migrate into the body's tissues through the venules.
用于抵抗感染的白细胞通常首先通过静脉毛细血管迁移到身体组织中。
In severe cases of trauma or shock, venules may constrict, limiting blood flow back to the heart.
在严重创伤或休克情况下，静脉毛细血管可能会收缩，限制血液回流至心脏。
During the process of angiogenesis, new venules develop to support increased blood flow in growing tissues.
在血管新生过程中，新的静脉毛细血管形成以支持生长中的组织增加的血流量。
Diseased or damaged venules can lead to edema and other complications if left untreated.
如果未经治疗，病态或受损的静脉毛细血管可能导致水肿和其他并发症。
