Illustration of the female reproductive system and its blood supply (vasculature), including the uterine artery and the ovarian artery. The anatomical relationship of the uterus, ovaries, and bladder is detailed in the inset.

Illustration of the female reproductive system: lateral pelvic wall, pelvic basin, ovaries, uterus, cervix, and vagina, anterior cutaway view.

Illustration of the upper respiratory system anatomy: nasal passage, hard palate, soft palate, tongue, uvula, epiglottis, pharyngeal muscles, vocal cords, and trachea. Air is shown moving freely through the airway to the lungs.

Illustration of the circulatory system in a female figure: heart, aortic arch, abdominal aorta, iliac arteries, femoral artery, popliteal artery, and tibial arteries, frontal view.

Illustration of the human female anatomy: skull, brain, eyes, facial nerve, mandible, common carotid artery, clavicle, ribs, lungs, heart, spleen, stomache, diaphragm, liver, pancreas, kidneys, pelvic bones, rectum, femoral artery, femur, patella, tibia, and fibula.

Illustration of the muscular, skeletal, and nervous systems in a figure, posterior view. Prominently shown are the upper back and arm muscles.

Illustration of a normal third trimester fetus in utero (left) and a fetus with umbilical cord abnormalities (right). The abnormalities shown are an unusually short cord and a nuchal cord, in which the umbilical cord wraps around the fetal neck.

Illustration of the kidney anatomy and physiology. Labels include the kidneys, renal arteries and veins, abdominal aorta, ureters, bladder, and urethra. Details of the kidney show blood circulation through the hilum and renal cortex (top right) and enlarged views of the kidney tissue and a nephron (lower right).

Illustration of the large intestine (colon) anatomy: appendix, cecum, ascending colon, right hepatic flexure, transverse colon, left splenic flexure, descending colon, sigmoid colon and rectum.

Illustration of the left lower leg, showing the nerves and bones: tibia, fibula, femur, patella, ankle, and foot bones.

Illustration of the normal anatomy of the hepatic and pancreatic ducts. Other anatomical structures shown are the liver, gallbladder, cystic duct, common bile duct, pancreas, and duodenum. The hepatic ducts carry bile from the liver, joining with the cystic duct to form the common bile duct, which itself conveys bile into the duodenum.

Illustration of the human skeletal system (skeleton), anterior and posterior views. Labeled bones include the skull, orbital cavity, maxillary bone, mandible, clavicle, sternum, scapula, humerus, costal cartilage, radius, ulna, sacrum, coccyx, femur, patella, tibia, and fibula.

Illustration of the normal brain, anterior view and cutaway section viewed from above. Labels identify the cerebrum, parietal lobe, occipital lobe, cerebellum, medulla oblongata, temporal lobe, and frontal lobe.

Illustration of the head and neck, showing the spinal accessory nerve and nearby muscles, side view. Labels include the spinal accessory nerve, cervical vertebrae (C2, C3, and C4), trachea, and the following muscles: temporalis, splenius capitis, levator scapulae, middle scalene, trapezius, masseter, and sternocleidomastoid muscles.

Illustration of the normal liver, stomach, and large and small intestines, frontal view. Labels include the liver, stomach, duodenum, ascending colon, terminal ileum, cecum, transverse colon, descending colon, sigmoid colon, and rectum.

Illustration of the cervical (neck) vertebrae.

Illustration of the abdomen, showing the anatomy of the retroperitoneal space in a male figure, anterior cutaway view. Labeled structures include the kindeys, abdominal aorta, inferior vena cava, peritonium, iliac arteries, spine, colon, testicular blood vessels, bladder, penis, femurs, and femoral arteries.

Illustration of the heart, showing the cardiac conduction system, cutaway view.

Illustration showing the relationship of the gallbladder to the cystic duct, common bile duct, cystic artery, and liver.

Illustration of the biliary region of the digestive system. Anterior cutaway view of the abdomen shows (left): liver, gallbladder, large intestine (colon), pancreas, and small intestine. Deeper anatomical structures shown include (right): liver, aorta, duodenum, greater duodenal papilla, jejunum, vena cava, and superior mesenteric blood vessels.
