What drains into the right subclavian vein?
What drains into the right subclavian vein?
The major part of the lymphatic fluid is drained via the thoracic duct, but the right side of the face and right upper extremity are drained into the right subclavian vein. Lymphatic flow depends upon the contraction of smooth muscle cells as well as external pressure, since the lymphatic system has very low pressure.
What veins drain into the subclavian vein?
The subclavian vein is a paired large vein, one on either side of the body, that is responsible for draining blood from the upper extremities, allowing this blood to return to the heart….
|Source||axillary vein, external jugular vein|
|Drains to||brachiocephalic vein|
What drains into the external jugular vein?
The external jugular vein is a superficial vein of the neck that drains blood from the parotid gland, most of the scalp, and side of the face, then back to the heart.
Where does left subclavian vein go?
The left subclavian trunk directly drains into the thoracic duct, and the right subclavian trunk continues to form the right lymphatic duct, which enters at the right venous angle (junction of the internal jugular vein and subclavian vein).
What does the cephalic vein drain into?
The cephalic vein, along with the basilic vein, is one of the primary superficial veins that drain the upper limb 1. It courses through both the forearm and arm and terminates by draining into the axillary vein.
What vein connects subclavian and brachial veins?
|Source||basilic vein, brachial veins, cephalic vein|
|Drains to||subclavian vein|
Where is the cephalic vein?
The cephalic vein is located on the anterior antebrachium. It crosses from the medial aspect of the leg an inch or so proximal to the carpus to join the brachial vein proximal to the elbow, which ultimately joins the external jugular vein.
What separates internal and external jugular vein?
Upon reaching the clavicle, it crosses the deep cervical fascia and ends by draining into the subclavian vein….External jugular vein.
|Drains from||Confluence of posterior division of the retromandibular vein with the posterior auricular vein|
|Drainage area||Scalp, face|
What happens if the subclavian vein is blocked?
This tissue causes the vein to narrow and restrict blood flow, leading to the formation of blood clots. Left untreated, axillo-subclavian vein thrombosis can cause: Arm pain and fatigue. Arm swelling.
Where is subclavian artery located?
The subclavian arteries lie just below the clavicles, providing blood supply to the bilateral upper extremities with contributions to the head and neck. The right subclavian artery derives from the brachiocephalic trunk, while the left subclavian artery originates directly from the aortic arch.
What are cephalic veins?
The cephalic vein is a superficial vein which courses along the anterolateral aspect of the arm and continues into the deltopectoral groove to empty into the subclavian vein.
What is the circumflex artery?
The circumflex branch of the left coronary artery primarily supplies the left ventricle. In the left-sided dominant coronary circulation, it gives off the posterior interventricular branch to supply the diaphragmatic surface of the myocardium. This article will discuss the anatomy and function of the circumflex artery.
Where does the circumflex artery join the posterior interventricular?
The circumflex artery ends at the point where it joins to form to the posterior interventricular artery in 15% of all cases, which lies in the posterior interventricular sulcus. In the other 85% of all cases the posterior interventricular artery comes out of the right coronary artery.
What happens when the circumflex artery reaches the left cardiac margin?
When the circumflex artery reaches the left cardiac margin, it wraps around the left side of the heart, emerging on its diaphragmatic surface. In most people, the circumflex artery terminates before reaching the crux of the heart. This is the point on the diaphragmatic surface where the interatrial and interventricular septa converge.
Where is the circumflex branch of the heart?
(Circumflex branch not visible, but would be near the coronary sinus .) Base of ventricles exposed by removal of the atria. (Circumflex branch not visible, but bifurcation of left coronary artery visible at left.) Posterolateral left ventricle, anterolateral papillary muscle, the sinoatrial nodal artery in 38% of people.
