Coronary circulation is the circulation of blood in the blood vessels of the heart muscle (myocardium). The vessels that deliver oxygen-rich blood to the myocardium are known as coronary arteries. The vessels that remove the deoxygenated blood from the heart muscle are known as cardiac veins.

A new research seems promising in curing the Diabetes type 1 permanently through Pancreatic Islet Transplantation. Islets are clusters of cells in the pancreas that make insulin which helps to convert food into energy.

Systemic circulation carries oxygenated blood from the left ventricle, through the arteries, to the capillaries in the tissues of the body. From the tissue capillaries, the deoxygenated blood returns through a system of veins to the right atrium of the heart.

The protein inside red blood cells (a) that carries oxygen to cells and carbon dioxide to the lungs is hemoglobin (b). Hemoglobin is made up of four symmetrical subunits and four heme groups. Iron associated with the heme binds oxygen.

Asthma is a condition in which your airways narrow and swell and produce extra mucus. This can make breathing difficult and trigger coughing, wheezing and shortness of breath.

Knee replacement, also called arthroplasty, is a surgical procedure to resurface a knee damaged by arthritis. Metal and plastic parts are used to cap the ends of the bones that form the knee joint, along with the kneecap. This surgery may be considered for someone who has severe arthritis or a severe knee injury.

Two common treatments for kidney failure are hemodialysis and peritoneal dialysis. With the right nursing assessments and interventions, your kidney failure patient can have a better chance at recovery.

We’re going over the roles that potassium plays in each of these two types of dialysis, as well as how stenosis monitoring can be used to prevent complications.

Why Does Thinking Hard Make You Tired?

an. 4, 2017 -- Scientists say they've identified a new organ in the body -- a swath of tissue dubbed the mesentery that connects the intestine to the abdomen and holds everything in place. For years, anatomical experts have thought the organ was composed of several different segments of tissue, as opposed to being one single structure, according to Discover magazine. Since an organ must be one structure that performs a vital function, it was not deemed worthy of organ status. But recent research from doctors at the University Hospital Limerick in Ireland shows that the mesentery is actually one single band of tissue, the magazine reported Tuesday. It begins at the pancreas and wraps around the small intestine and colon. Its purpose: to hold these organs in position so they can perform their respective functions. "Without it you can't live," lead researcher Dr. J. Calvin Coffey, a colorectal surgeon at Limerick, told the magazine. "There are no reported instances of a Homo sapien living without a mesentery." "Understanding how and why our digestive system is arranged the way it is could be crucial to our understanding of diseases like Crohn's and irritable bowel syndrome," Coffey added. "There are a lot of diseases that we are stalled on, and we need to refresh our approach to these diseases," Coffey said. "Now that we've clarified its [the mesentery's] structure, we can systematically examine it. We're at a very exciting place right now." The discovery was published recently in the Lancet Gastroenterology & Hepatology journal.

Although the Apgar score was developed in 1952 by an anesthesiologist named Virginia Apgar, you also might hear it referred to as an acronym for: Appearance, Pulse, Grimace, Activity, and Respiration. The Apgar test is usually given to a baby twice: once at 1 minute after birth, and again at 5 minutes after birth.

Marfan syndrome is a genetic disorder that affects the body’s connective tissue. Connective tissue holds all the body’s cells, organs and tissue together. It also plays an important role in helping the body grow and develop properly. marfan_general_2.jpg What is Marfan Syndrome?Connective tissue is made up of proteins. The protein that plays a role in Marfan syndrome is called fibrillin-1. Marfan syndrome is caused by a defect (or mutation) in the gene that tells the body how to make fibrillin-1. This mutation results in an increase in a protein called transforming growth factor beta, or TGF-β. The increase in TGF-β causes problems in connective tissues throughout the body, which in turn creates the features and medical problems associated with Marfan syndrome and some related disorders. Because connective tissue is found throughout the body, Marfan syndrome can affect many different parts of the body, as well. Features of the disorder are most often found in the heart, blood vessels, bones, joints, and eyes. Some Marfan features – for example, aortic enlargement (expansion of the main blood vessel that carries blood away from the heart to the rest of the body) – can be life-threatening. The lungs, skin and nervous system may also be affected. Marfan syndrome does not affect intelligence.

The pituitary gland is often portrayed as the "master gland" of the body. Such praise is justified in the sense that the anterior and posterior pituitary secrete a battery of hormones that collectively influence all cells and affect virtually all physiologic processes. The pituitary gland may be king, but the power behind the throne is clearly the hypothalamus. As alluded to in the last section, some of the neurons within the hypothalamus - neurosecretory neurons - secrete hormones that strictly control secretion of hormones from the anterior pituitary. The hypothalamic hormones are referred to as releasing hormones and inhibiting hormones, reflecting their influence on anterior pituitary hormones.

Women's College Hospital is revolutionizing the way knee-replacement surgery is done. It is starting to provide the procedure as an ambulatory service. Patients can go home from hospital four hours after having the surgery. In some other hospitals knee replacement surgery patients have to stay as long as 4 days.

Read an excerpt from Theresa Boyle's story:
It’s been less than four hours since Greg Nemez underwent knee-replacement surgery and the 56-year-old Mississauga man is already on his way home from hospital.

This past Monday, he became the fifth patient at Toronto’s Women’s College Hospital to undergo the outpatient procedure, which normally requires a hospital stay of two or three days.

“I’m happy ... You have that freedom of movement from before. It’s like wow,” he said on the elevator as he was leaving the hospital.

After years of being unable to hold his leg straight, the real-estate agent can finally do so. A 20-year-old football injury had left him with severe arthritis and pain.

patient has fever, hypotension, swelling, and erythema of his left leg. Notably, his leg is more painful to palpation than might be expected after visual inspection. These symptoms are very concerning for necrotizing fasciitis. Necrotizing fasciitis is a fulminant infection of the subcutaneous tissue that spreads rapidly along the fascial planes and leads to extensive tissue necrosis and shock. Treatment • Requires surgical debridement & broad-spectrum antibiotics
