The Warning Signs of Retinal Detachment & What You Should Do

Retinal detachment is a medical condition strongly linked with changes in the eye due to normal aging. The eye disorder presents a serious concern because, unlike many other illnesses, no pain is involved when the retina detaches. If left untreated, retinal detachment can cause permanent vision loss. Being aware of the warning signs and knowing what to do if they occur is essential.

Although the heart is a complicated organ, in essence, it is a pump that continuously works to circulate blood throughout the body.

The heart is an organ that weighs approximately 350 grams (less th

The Anatomy of the Biliary System

The biliary system, also called the biliary tract or biliary tree, is a system of ducts (narrow tubular structures), organs (including the liver, gallbladder, and pancreas), and associated structures that function to produce, store, secrete, and transport bile.

Bile is a greenish-brown, thick substance produced in the liver and stored in the gallbladder. Bile’s function is to be released into the small intestine when a fatty meal is ingested to help break down fats for absorption.

The Integumentary System: Your Skin, Hair, Nails, and Glands

The integumentary system is made up of several organs and structures including the skin, hair, nails, glands, and nerves. The primary function of the integumentary system is to protect the inside of the body from elements in the environment—like bacteria, pollution, and UV rays from the sun.

The skin and its associated structures also retain bodily fluids, eliminate waste products, and regulate the body’s temperature. The integumentary system works with all other bodily systems—such as the nerv

The Anatomy of the Coronary Sinus

The coronary sinus is a large vein that that returns deoxygenated blood from the heart muscle to the right side of the heart so that it can be replenished with oxygen.

The coronary sinus is located on the heart’s posterior (behind) surface and is positioned between the left ventricle and the left atrium. All mammals, including humans, are known to have a coronary sinus.

The length of the coronary sinus is from 15 to 65 millimeters (0.59 to 2.5 inches). It is wider than most of the coronary vei

The Anatomy of the Subclavian Artery

Arteries are large blood vessels that carry oxygenated blood from the heart to the cells, tissues, and organs throughout the body. They can be found in every part of the body (except the hairs, nails, upper layer of the skin, cartilage, and cornea of the eye).

The subclavian artery is a major blood vessel located in the thorax (chest area) that functions to carry oxygen-rich blood from the heart to parts of the upper body, including the:

The Anatomy of the Duodenum

The duodenum, the first and shortest section of the small intestine, is a key organ in the digestive system. The small intestine’s most important function is to digest nutrients and pass them into the blood vessels—located in the intestinal wall—for absorption of the nutrients into the bloodstream.

Together, the duodenum and other organs of the alimentary canal (the pathway by which food enters the body and solid wastes are expelled) form the digestive system of the body.

The duodenum has been

The Anatomy of the Small Intestine

The small intestine—commonly referred to as the small bowel—is a tubular structure/organ that is part of the digestive system. In fact, it is the longest portion of the digestive system, approximately 20 to 25 feet in length.

It is referred to as the “small” intestine because its lumen (opening) is smaller in diameter (at approximately 2.5 centimeters or 0.98 inches) than the large intestine (colon).

The primary function of the small intestine is to break down and absorb ingested nutrients whi

The Anatomy of the Superior Vena Cava

Veins are tubular, hollow structures that form part of the circulatory system of the body; in most instances, veins carry deoxygenated blood toward the heart. The superior vena cava (SVC) is one of the two largest veins in the body and is considered one of the many systemic veins. Systemic veins are those carrying deoxygenated blood from various areas of the body to the heart and are vital to the function of the cardiovascular system.

The importance of the superior vena cava is its function in
