blood vessel
A tube-like structure in the body of humans and animals through which blood is transported, such as an artery, vein, or capillary.
Durch ein verengtes Blutgefäss kann der Blutfluss behindert werden.
Blood flow can be obstructed by a narrowed blood vessel.
The word is a clear compound of 'das Blut' (blood) and 'das Gefäß' (vessel/container). A 'Gefäß' is a container, so a blood vessel is literally a 'container for blood'.
Rauchen kann die Blutgefäße schädigen.
Smoking can damage the blood vessels.
In a medical context, 'Blutgefäß' (blood vessel) is often used with verbs such as 'verengen' (to narrow/constrict), 'erweitern' (to dilate/expand), 'verkalken' (to calcify), or 'schützen' (to protect).
Sport hilft dabei, die Blutgefäße elastisch zu halten.
Exercise helps keep the blood vessels elastic.
Although it is a medical technical term, 'Blutgefäß' (blood vessel) is also widely used in everyday language when talking about health topics.
Der Arzt erklärte mir, wie wichtig gesunde Blutgefäße sind.

vessel / container
'das Gefäss' and 'das Blutgefäss' can mean almost the same thing in the body when the transport of blood is involved. However, 'Gefäss' is more general. In anatomy, it can also refer to other fluids in the body, and outside medicine it can even mean a container. 'Blutgefäss' is more precise: it always refers to a structure through which blood flows. Learners may confuse the words because 'Gefäss' is often used as a short form of 'Blutgefäss' in medical contexts. If you want to be clear and precise that blood is meant, 'Blutgefäss' is better.
