The superior, middle, and inferior rectal arteries supply blood to the rectum, arising from the inferior mesenteric, internal iliac, and internal pudendal arteries respectively. Venous drainage mirrors the arterial supply, with the superior rectal vein draining into the portal system and the middle and inferior rectal veins draining into the internal iliac vein. Lymphatic drainage also parallels the vascular system, with channels in the upper and middle rectum draining to the inferior mesenteric lymph nodes and channels in the lower rectum draining to both the inferior mesenteric and internal iliac lymph nodes.

Duplex ultrasound of Vericose vein
Varicose veins are dilated, elongated superficial veins caused by venous hypertension. They commonly occur in the legs but can affect other areas. The venous system of the lower limb consists of deep and superficial veins that connect via perforating veins. The long saphenous vein originates in the foot and travels up the medial leg and thigh, connecting to the femoral vein. Short saphenous vein originates laterally and connects to the popliteal vein. Valves in the veins normally prevent backflow but can become incompetent, allowing reflux and varicose vein formation. Color duplex ultrasound can evaluate reflux patterns and valve competence.

Ureter, bladder & urethra lab summary
The document describes the anatomy of the ureter, bladder, and urethra. It discusses the length, parts, relations, blood supply, and lymph nodes of the ureter. It outlines the ligaments, relations, sphincter, blood supply, nerves, and lymph nodes of the bladder. It details the sphincters, parts, blood supply, and lymph nodes of the male and female urethra.
Anatomy of venous system of lower limb
The document summarizes the anatomy of the venous system in the lower limb. It describes the three main components: deep veins, superficial veins, and perforating veins. The major superficial veins are the long and short saphenous veins. The long saphenous vein runs from the foot up the leg and thigh, draining into the femoral vein. It has numerous tributaries along its path. The short saphenous vein drains the back of the calf and popliteal fossa, joining the popliteal vein. Perforating veins connect the superficial and deep systems to allow for bidirectional flow of blood.
Lymphatic drainage of lower limb
The lymphatic system drains tissue fluid, plasma proteins, and cellular debris from the lower limb into lymph vessels. The lymph is then filtered by lymph nodes and directed into the venous system. There are superficial and deep lymphatic vessels in the lower limb. The superficial vessels follow the great and small saphenous veins, while the deep vessels accompany the anterior tibial, posterior tibial, and peroneal arteries and drain into the popliteal lymph nodes. Lymphadenopathy is abnormal swelling of lymph nodes, usually due to infection, malignancy, or autoimmune conditions. Enlarged inguinal lymph nodes could indicate issues with the lower limb or genital region.
Hepatic Portal vein and portocaval anatomosis
The hepatic portal vein drains blood from the abdominal organs into the liver before exiting into the inferior vena cava. It forms at the union of the superior mesenteric and splenic veins. In the liver, it divides into right and left branches that further branch into hepatic sinusoids. Portosystemic anastomoses allow blood to bypass the liver in portal hypertension, leading to collateral circulation and varices in locations like the esophagus, anus, and abdomen.
PULMONARY CIRCULATION PHYSIOLOGY
The document summarizes the pulmonary circulation. The pulmonary artery carries deoxygenated blood from the right ventricle to the lungs. In the lungs, the blood is oxygenated and carried by the pulmonary veins back to the left atrium. The bronchial artery supplies oxygenated blood to other lung structures. There is also a small physiological shunt where some deoxygenated blood from the bronchial circulation mixes with oxygenated blood in the pulmonary veins without being oxygenated.
Normal anatomy and congenital anomalies of vena cavae
This document discusses the normal anatomy and common congenital anomalies of the superior and inferior vena cavae. It begins with an overview of the embryological development of the vena cavae. It then describes the normal anatomy of the superior and inferior vena cavae and their major tributaries. Common congenital anomalies are then outlined, including double superior vena cavae, left-sided superior vena cava, left inferior vena cava, double inferior vena cava, azygos continuation of the inferior vena cava, and circumcaval anomalies of the left renal vein and ureter. Clinical significance is discussed for some anomalies.
Circulation of liver & Portosystemic collaterals
The document summarizes the circulation of the liver and portosystemic collateral veins. It discusses:
- The dual blood supply to the liver from the hepatic artery (25-30% of flow) and portal vein (70-75% of flow).
- The portal vein is formed by the superior mesenteric vein and splenic vein. It divides within the liver into right and left branches.
- Portosystemic collateral veins develop to bypass portal hypertension and include veins around the falciform ligament, umbilical veins, and abdominal wall veins.
- The presence of dilated umbilical or abdominal wall veins indicates high pressure within the left branch of the portal vein and

Radial artery
Ulnar artery
In this article, we shall look at the anatomy of the arteries of the upper limb – their anatomical course, branches and clinical correlations.
Upper limb Blood Supply arteries.pptx
The upper limb is supplied by three main arteries:
1) The subclavian artery becomes the axillary artery as it passes into the arm, further dividing into the brachial artery.
2) The brachial artery then bifurcates into the ulnar and radial arteries in the forearm.
3) These arteries anastomose throughout the arm and forearm, additionally supplying branching vessels to surrounding muscles and bones.
Veins of the upper limb mirror the arterial system, with superficial veins like the cephalic and basilic draining into deep brachial, axillary, and subclavian veins. The superficial veins connect at the elbow before joining the deep venous system.

11. superfacial veins of the upper limb
The superficial veins of the upper limb include the cephalic vein and basilic vein. The cephalic vein originates on the back of the hand and travels up the lateral forearm and arm, terminating in the axillary vein. The basilic vein also originates on the back of the hand, traveling medially up the forearm and arm where it joins the brachial artery to form the axillary vein. The median cubital vein is a branch of the cephalic vein that crosses in front of the brachial artery and median nerve in the cubital fossa before joining the basilic vein. The superficial lymph vessels follow similar paths to the cephalic and basilic veins to drain into lymph
The veins of the lower limb
The veins of the lower limb can be divided into three groups: superficial, deep, and perforating. The superficial veins include the great and small saphenous veins. The great saphenous vein runs along the medial leg and thigh and joins the femoral vein. The small saphenous vein runs along the back of the leg and joins the popliteal vein. The deep veins include the venae comitantes of the leg arteries and the popliteal, femoral, and iliac veins. Perforating veins connect the superficial and deep veins. Valves in the veins ensure blood flow moves upwards from the feet. Varicose veins can develop when valves are incompetent.
Vascular anatomy of extremities
This document summarizes the vascular anatomy of the upper and lower extremities. In the upper extremity, it describes the arterial supply from the subclavian artery and its branches down to the palmar arches. It also describes the deep and superficial venous drainage. In the lower extremity, it outlines the arterial supply from the femoral artery through the profunda femoris, popliteal, tibial and peroneal arteries. It also maps the deep and superficial venous drainage including the great and small saphenous veins. The document notes some common anatomic variations and clinical implications such as thoracic outlet syndrome, arteriovenous fistula mapping, and varicose veins.
Urethral anatomy
The document provides an overview of male urethral anatomy including:
- The urethra extends from the bladder neck to the penile meatus and has both anterior and posterior portions.
- It passes through the prostate and is surrounded by muscles that aid in continence.
- The urethra has a dual blood supply to allow for mobilization during surgery.
- Knowledge of the anatomy is important for successful management of strictures and other anomalies.
Lymphatic system
The lymphatic system consists of lymph vessels, lymph nodes, and lymphoid tissues that work together to drain excess fluid from tissues, absorb and transport fatty acids from the gut, and help fight infection. Lymph is formed when interstitial fluid drains into initial lymphatic vessels and circulates through a network of vessels, nodes, ducts, and eventually returns to the bloodstream. Lymph nodes filter lymph as it circulates and contain immune cells that help fight pathogens. The major lymphatic ducts are the thoracic duct and right lymphatic duct which drain lymph into the bloodstream in the neck.
lymphaticsystem-181202101207.pdf
The lymphatic system consists of lymph vessels, lymph nodes, and lymphoid tissues that work together to drain excess fluid from tissues, absorb and transport fatty acids from the gut, and help fight infection and disease. Lymph is formed from interstitial fluid that has leaked from blood vessels and is transported through unidirectional lymph vessels to lymph nodes where it is filtered and returned to the bloodstream to maintain fluid balance. The major components of the lymphatic system include lymph, lymph vessels, lymph nodes, and lymphoid organs that circulate lymph in a stepwise fashion throughout the body.
Arterial Supply and Venous Drainage of Pelvis.pptx
The rich vascular supply of the pelvis not only supports the structures contained within it, including the bladder, rectum, and reproductive organs, but also extends to the lower extremities. For a complete understanding of vascular anatomy as it pertains into the endovascular procedures of interventional radiology, it is useful to discuss the vascular structures in sections, from the bifurcation of the aorta and the inferior vena cava to the level of the common femoral arteries and veins. We will also review the anatomy of the iliac vessels, including their branches, common variants, and various collateral pathways
Venous anatomy of brain - Radiology
The document summarizes the cerebral venous system, including:
- Cerebral veins drain the brain and lack valves, emptying into dural venous sinuses between the dura layers.
- The major dural venous sinuses include the superior and inferior sagittal, straight, occipital, transverse, sigmoid, and cavernous sinuses.
- The sinuses receive blood from cerebral veins and CSF from arachnoid villi before draining into the internal jugular veins.
LYMPHATIC DRAINAGE OF GIT.pdf
The lymph vessels from different parts of the gastrointestinal tract drain to specific lymph nodes before eventually reaching one of two central lymph node groups - the celiac nodes or superior mesenteric nodes. The esophagus, stomach, duodenum and parts of the colon drain to the celiac nodes, while the jejunum, ileum, cecum, appendix, parts of the colon and descending colon drain to the superior mesenteric nodes.
Blood vessels of Upper Limb.pptx
The document summarizes the major blood vessels of the upper limb, including both arteries and veins. It describes the five main arterial vessels that supply blood from proximal to distal as the subclavian, axillary, brachial, radial, and ulnar arteries. It then provides details on each of these vessels, including branches, parts, and clinical relevance such as sites for measuring blood pressure and potential complications from occlusion. It also outlines the superficial and deep venous systems that drain the upper limb, noting key veins like the basilic and cephalic as well as the median cubital vein which is a common site for blood draws.
Blood supply of female pelvis.
The document summarizes the blood supply of the female pelvis. It describes the branches of the internal iliac artery and vein that supply various pelvic structures like the uterus, vagina, ovaries and rectum. It also discusses variations in pelvic vasculature and anastomoses between vessels that allow for collateral blood flow. Applied clinical points are mentioned, such as the risk of ureter injury during uterine artery ligation and routes for metastatic spread from pelvic cancers.
femoralartery-180430021308.pdf
The femoral artery is the main artery of the lower limb. It enters the femoral triangle behind the inguinal ligament and runs downwards through the femoral triangle and adductor canal before becoming the popliteal artery. It has many branches that supply structures in the thigh like the profunda femoris artery. The femoral artery can be palpated in the femoral triangle and is often used for procedures like angiography due to being superficial in this region.

- 24. Arterial supply • The superior rectal artery arises from the terminal branch of the inferior mesenteric artery and supplies the upper rectum. • The middle rectal artery arises from the internal iliac artery • The inferior rectal artery arises from the internal pudendal artery, which is a branch of the internal iliac artery. • A rich network of collaterals connects the terminal arterioles of each of these arteries, thus making the rectum relatively resistant to ischemia
- 25. Venous drainage • The superior rectal vein drains into the portal system via the inferior mesenteric vein. • The middle rectal vein drains into the internal iliac vein. • The inferior rectal vein drains into the internal pudendal vein, and subsequently into the internal iliac vein. • A submucosal plexus deep to the columns of Morgagni forms the hemorrhoidal plexus and drains into all three veins
- 26. Lymphatic drainage • Parallels the vascular supply • Lymphatic channels in the upper and middle rectum drain superiorly into the inferior mesenteric lymph nodes • Lymphatic channels in the lower rectum drain both superiorly into the inferior mesenteric lymph nodes and laterally into the internal iliac lymph nodes.
