The tunica media is the thickest tunic; it is predominantly muscular in arterioles and most arteries, and it is predominantly elastic in the largest arteries (the so-called elastic arteries such as the aorta and the common carotid).
What is the main vein?
The superior vena cava carries blood from the arms and head to the right atrium of the heart, while the inferior vena cava carries blood from the legs and abdomen to the heart. The portal venous system is a series of veins or venules that directly connect two capillary beds.
Which leg is your main artery in?
The femoral artery is a large artery in the thigh and the main arterial supply to the thigh and leg.
What are the 3 main heart arteries?
What are the two major coronary arteries?
- Right coronary artery supplies the right atrium and right ventricle with blood.
- Left main coronary artery branches into the circumflex artery and the left anterior descending artery.
Which is the smallest vein in human body?
The smallest veins in the body are called venules. They receive blood from the arteries via the arterioles and capillaries. The venules branch into larger veins which eventually carry the blood to the largest veins in the body, the vena cava.
What is the strongest vein in the body?
All the arteries of the body, save the pulmonary arteries, stem from the aorta or one of its main branches. Vena Cava are large veins that return deoxygenated blood from the body into the heart. In humans they are called the superior vena cava and the inferior vena cava, and both empty into the right atrium.
What vein is the best to shoot up in?
To shoot dope, you need to find a vein. The best place to look for veins is the crook of the arm. These are called the cubital fossa, to be technical.
What is the smallest vessel in the body?
What is the biggest vein in the heart?
The largest vein in the human body is the inferior vena cava, which carries deoxygenated blood from the lower half of the body back up to the heart.
Which layer is thickest in veins?
The outer layer (tunica adventitia) consists chiefly of connective tissue and is the thickest layer of the vein. As in arteries, there are tiny vessels called vasa vasorum that supply blood to the walls of the veins and other minute vessels that carry blood away.
What are the 3 main veins to draw blood?
Median cubital vein A superficial vein, most commonly used for venipuncture, it lies over the cubital fossa and serves as an anastomosis between the cephalic and basilic veins. 2. Cephalic vein Shown in both forearm and arm, it can be followed proximally where it empties into the axillary vein.

- Chest pain.
- Shortness of breath.
- Heart palpitations.
- Weakness or dizziness.
Is a blocked artery in the leg dangerous?
The most dangerous symptom is known as critical limb ischemia. Ischemia means tissue damage caused by lack of blood and oxygen. In the case of PAD, it can be triggered by a blood clot that blocks a narrowed artery.
