What vein runs with brachial artery?
The brachial vein (deep vein) accompanies the brachial artery in the region of the arm. It is formed by the unification of the ulnar and radial veins at the elbow. The basilic vein joins the brachial vein and becomes the axillary vein at the inferior border of the teres major muscle.
Is the brachial artery a vein?

What are the 3 main veins to draw blood?
The most site for venipuncture is the antecubital fossa located in the anterior elbow at the fold. This area houses three veins: the cephalic, median cubital, and basilic veins (Figure 1).
What is the longest vein in the body?
Great Saphenous Vein
Did you know that your Great Saphenous Vein is the longest vein in the human body? Extending from the top of your foot to the upper thigh and groin, THIS vein is the major culprit that causes Varicose Veins.
How do you know if you hit an artery instead of a vein?
Puncture of an artery may be more uncomfortable than puncture of a vein. This is because arteries are deeper than veins. Arteries also have thicker walls and have more nerves. When the needle is inserted, there may be some discomfort or pain.
Where are the main veins in your arm?
At the top of the arm it lies between the deltoid and pectoralis major. The large vein crossing the front of the elbow is the antecubital vein. It crosses from the cephalic, to the basilic vein. The basilic vein then runs up the medial aspect of the arm to join this brachial vein, which is one of a pair.

What is the function of the brachial vein?
The brachial artery is the main vessel supplying blood to the muscles in your upper arm and elbow joint. It’s often used to measure your blood pressure.
What happens if you cut your brachial artery?
The Brachial artery runs along the inside of your arms. This artery is deep, but severing it will result in unconsciousness in as little as 15 seconds, and death in as little as 90 seconds.
What is the easiest vein to draw blood?
median cubital vein
For adult patients, the most common and first choice is the median cubital vein in the antecubital fossa. Commonly referred to as the antecubital or the AC it can be found in the crevice of the elbow between the median cephalic and the median basilic vein.
Which is the smallest vein?
Capillaries. Capillaries, the smallest and most numerous of the blood vessels, form the connection between the vessels that carry blood away from the heart (arteries) and the vessels that return blood to the heart (veins).
What is the smallest blood vessel?
Capillaries
Capillaries are the smallest blood vessels in the body. How small are they? About ten of them equal the thickness of one human hair, and most are so small that only one blood cell can pass through them at a time. Explain that smoking harms your blood cells and blood vessels, including tiny capillaries.
What happens if you stick a needle in an artery?
Hitting an artery can be painful and dangerous. Arterial blood travels away from the heart so whatever is injected goes straight to body limbs and extremities. Injection particles get stuck in blood capillaries and cut off circulation. This can result in a lack of blood flow, eventually causing the tissue to die.
Can you accidentally hit an artery when drawing blood?
Whole blood is drawn from the vein of a blood donor, however an arterial phlebotomy may happen accidentally.

Veins of the arm and axilla include superficial veins (cephalic and basilic veins) and deep veins (brachial and axillary veins).
What are the 3 main veins in the arm?
What does the brachial artery supply?
Once the brachial artery reaches the cubital fossa, it divides into its terminal branches: the radial and ulnar arteries of the forearm. The brachial artery and its branches supply the biceps brachii muscle, triceps brachii muscle, and coracobrachialis muscle.
How deep is the brachial artery?
Course. As a continuation of the axillary artery, it begins at the inferior border of the teres major tendon and it ends at the level of the neck of the radius about 1cm distal to the elbow joint.
What is the most vulnerable artery?
The brachial artery is the most frequently injured artery in the upper extremity due to its vulnerability.
What veins should you avoid?
While hand veins may be utilized for blood draws and intravenous infusions, veins in the feet and legs should be avoided for adults. Drawing from these sites can cause blood clotting and hemostasis.

What are the 3 types of veins?
There are four types of veins:
