It is situated just below the diaphragm, to the right of the stomach and on top of the gallbladder. There are two ways blood can travel to and from the liver: the hepatic artery and the portal vein. The hepatic artery carries blood solely...
The esophagus is the muscular tube that is located between the pharynx and the stomach that aids in digestion during swallowing. Formation and Orientation The esophagus is composed of four separate layers; the mucosa, submucosa, muscularis externa and the adventitia. The mucosa includes the stratified squamous epithelium, lamina propria and muscularis mucosae. The submucosa houses the esophageal glands and connective papillae. The muscularis externa is composed of three sublayers The...
The ovaries are the two reproductive female organs where the eggs are produced. These are parallel to the testes in men. Formation and Orientation Each ovary is the size of an almond and is located on one side of the pelvis before the ureter and internal iliac artery but after the external iliac artery. They are attached to either side of the uterus. They are connected and release eggs to fallopian tubes, though not attached, monthly during the menstrual cycle. They also produce...
Skin is the outermost organ that protects and incases the tendons, ligaments, bones, muscles, etc. It is also the largest organ of the human body. Formation and Orientation Healthy skin consists of vitamins A, C, D and E, but in all skin, there are melanocytes which produce mesodermal cells. These cells allow for the absorption of UV rays. There are five main pigments that provide color in the skin’s many levels. Although not found in the skin, Oxyhemoglobin is found in the blood,...
The appendix is a dead-end tube like structure, ranging from 2 to 20 cm, that spans off the cecum of the colon. It is attached to the lower part of the large intestine. Formation and Orientation The appendix can be found in many mammals including marsupials, euarchontoglires (rodents) as wells as humans of course.
