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 are the two types of veins?
Veins. The pulmonary veins carry oxygenated blood from the lungs to the left atrium of the heart. Systemic veins carry low-oxygen blood from the body to the right atrium of the heart.

Where is the brachiocephalic vein?
thoraxThe brachiocephalic veins also referred to as the innominate veins, are large venous structures located within the thorax and originate from the union of the subclavian vein with the internal jugular vein. The left and right brachiocephalic vein join to form the superior vena cava on the right side of the upper chest.
Where is the dorsal venous arch located?
Dorsal venous arch of the foot. The dorsal venous arch of the foot is superficially located near the skin surface. For most people, it should be easily visible on their foot’s upper side. If a person were to press their finger against it, they should be able to feel a pulse. The pulse is from the dorsalis pedis artery.
Where does blood flow from the arch?
Eventually, the blood flows into many other vessels in the venous system as it travels up the leg and back to the lungs and the heart.
What is the function of the arch?
The arch assists in draining oxygen-depleted blood from the foot. Also, it receives blood from the dorsal metatarsal veins, which drains the foot’s metatarsal region (the area leading to the toe bones) and drains the dorsal digital veins servicing the toes.
What is the purpose of the arterial vessels in the foot?
Unlike veins, these arterial vessels deliver oxygenated blood from the lungs and heart, which allows for proper functioning of the foot’s muscles, tendons, and ligaments. Last medically reviewed on January 19, 2018.
Where is the pulse on the foot?
If a person were to press their finger against it, they should be able to feel a pulse. The pulse is from the dorsalis pedis artery. The arch assists in draining oxygen-depleted blood from the foot.
Where is the dorsal venous arch?
The dorsal venous arch lies at the distal portions of the metatarsal bones. There are medial and lateral marginal veins, which drain both of the dorsal and plantar aspects of the particular sides within the dorsal venous arch alongside the foot.
Where do the dorsal veins originate?
10 dorsal digital veins originate through sides of the toes. Surrounding 8 veins merge at the web of the toes creating 4 dorsal metatarsal veins. They merge and create dorsal venous arch, being located opposite the middle of the dorsum of foot, which connects with the venous system at the dorsum of the foot as well as in front of the ankle.
What is the function of the arch?
Functions. The arch helps in draining oxygen-depleted blood through the foot. Also, it gets blood via the dorsal metatarsal veins, which drains the foot’s metatarsal area and also drains the dorsal digital veins supplying the toes.
Which vein drains blood from the calf?
Small saphenous vein: drains blood via the lateral dorsal venous arch along with posterior leg (calf) within the popliteal vein posterior towards the knee. Great saphenous vein: drains blood via the medial dorsal venous arch, leg, as well as thigh within the femoral vein just inferior towards the inguinal ligament.

What is the dorsal vein?
The dorsal venous arch of the foot is a superficial vein that connects the small saphenous vein and the great saphenous vein. Anatomically, it is defined by where the dorsal veins of the first and fifth digit, respectively, meet the great saphenous vein and small saphenous vein.
Anatomy
Course A superficial vein that joins the great and small saphenous veins. It starts where the first dorsal digital vein of the foot meets with the great saphenous vein and connects to the small saphenous vein where it meets the fifth dorsal digital vein of the foot.
Drain
Receives tributaries from the dorsal digits and creates and anastomotic connection between the great and small saphenous vein.
Clinical
Can be easily palpated in a clinical setting just above the metatarsal bones.
