Blood travels away from the heart through arteries and to the heart through the veins.
Veins are thin walled, with valves in them and with a wide lumen (central opening, the space that blood flows).
Arteries are thick, muscular walled with many different layers and with a narrow lumen.
In most cases, veins carry oxygen depleted blood (blue blood) from the tissues while arteries carry oxygen rich blood (red blood) to the tissues. However, the pulmonary artery carries oxygen depleted blood from the heart to the lungs. The pulmonary veins carry oxygen rich blood to the heart from the lungs.
Arterie
Yes of coarse Arterie= oxygenated blood Vein= deoxygenated blood Capillarie= link to the vein from arterie
Arteries are connected to veins through capillary beds in the body tissues.
aorta
Pulmanry arterie
aorta definitely....
There is no portal artery. A portal vein connects one capillary bed to a second capillary bed. (in series)
femoral arteries
Vena Cava
pulmonary arterie
The aorta is the main artery coming out of the heart.
However many you want there to be.
