The appendix is sometimes referred to as the 'abdominal tonsil' because it is composed largely of lymphoid tissue and is very susceptible to infection. It varies greatly in size, the average length being 75 mm. Normally it is a hollow tube lined with mucous membrane, with a muscle wall similar to that of the caecum with which it communicates. Its tip may hang down over the brim of the pelvis to make contact with the bladder, the rectum, or in the female with the ovary, uterine tube or uterus. It may on the other hand, turn upwards behind the caecum pointing out towards the groin-the retro-caecal position. It may lie on the front of the caecum immediately under the anterior abdominal wall.

Bubo is an inflammatory swelling of a lymphatic gland in any part of the body. The term is usually confined to swelling of the glands of the groin.

Dhobi itch (tinea cruris) is a fungal disease of the skin caused by a type of ringworm chiefly affecting the area around the groin.

At the groin, the iliac arteries become femoral arteries, which continue down the front and inner part of the thighs becoming the popliteal arteries at the knee joint. The
femoral arteries carry a fresh supply of blood to the greater part of the legs.
Research Femoral Arteries
The femoral vein extends up the inner thigh along the femoral artery toward the groin where it joins with the internal saphenous vein and becomes the external iliac. The
femoral vein receives the greater part of the blood from the legs. This vein has four or five valves to assist in the transport of blood. The valves open to let blood through, and close to prevent it from flowing backward.

The ilioinguinal nerves branch off of the spinal cord at the first lumbar vertebra. They extend down the abdominal wall to the groin, external genitals, and the upper thigh.

The network of lymph vessels in the lower body passes lymph into the bean-sized inguinal nodes deep in the groin. The inguinal lymph nodes can be grouped as superficial and deep. The deep
inguinal lymph nodes are situated near the femoral artery and vein. They receive lymph from the lower limbs, external genitalia, and lower anterior abdominal wall. The superficial
inguinal lymph nodes can be found along the greater saphenous vein. The receive lymph from the external genitalia, and the superficial parts of the lower limbs.
Research Inguinal Lymph Nodes
Lymph nodes, or lymph glands as they are sometimes called, are small oval structures normally the size of small kidney beans. They generally are located in clusters near veins at strategic points along medium-sized lymph vessels at the knee, elbow, armpit, groin, neck, abdomen and chest. Blood is cleaned and filtered in the lymph nodes, and germ fighting cells gather there during illness. This filtration process prevents bacteria, cancer cells, and other infectious agents from entering the blood and circulating through the system. The lymph nodes are the centers for production and storage of some of the white blood cells, namely the lymphocytes and monocytes, which are important elements of the body's immune mechanism. During any kind of infection, the nodes enlarge in their area of drainage due to the multiplication of lymphocytes in the node.

The scrotum is the protective skin pouch which contains the testes (testicles). It is located in the groin, on the outside of the abdominal cavity. This positioning allows the testicles to remain at a temperature slightly below body temperature, a critical condition in the development of viable spermatozoa. After puberty, the hair begins to grow on the scrotum and nearby skin. This pubic hair remains for the rest of the adult life.

A T bandage is a bandage shaped like the letter T used principally for application to the groin, or perineum.
