describ the position of venous blood vessels in relation to arteries, nerves and other structures
circulatory system
They supply the brain (and structures of the head, as well) with oxygenated blood.
The veins carries blood from the body to the heart.
Although it is an arguable topic whether blood is ever truly blue at one point or not, we'll just go along with the common lesson that "blue blood" is blood that is not oxygen-rich. This blue blood is carried in the pulmonary artery, where it is taken to the lungs in order to obtain oxygen, where it is then sent back to the heart, then sent to the rest of the body.
muscular arteries
Properly called the trachea, the windpipe is surrounded by several structures. These anatomical structures, include the thyroid gland, lymph nodes, esophagus. carotid arteries, epiglottis and cervical vertebrae.
Tunica adventitia is poorly developed in arteries then in veins
Capillaries are the structures that connect arteries to veins.
they are the san
Anastomosis is the anatomical reconnection of two tubular organs, such as the intestine.
the two pulmonary arteries lead to hogwarts and narnia.
Arteries are called arteries because they ALWAYS take blood away from the heart. Veins ALWAYS take blood back to the heart. It does not matter if they have blood high in oxygen or not. These are anatomical terms not physiological terms.
Capillaries do
heart arteries veins
Arteries
they are the san
The main structures of the cirulatory system are: the heart, the arteries, veins and capillaries.
