The cell membrane is selectively permeable to ions and organic molecules and controls the movement of substances in and out of cells. The basic function of the cell membrane is to protect the cell from its surroundings. It consists of the phospholipid bilayer with embedded proteins.
kin grafting is a type of graft surgery involving the transplantation of skin. The transplanted tissue is called a skin graft. Skin grafting is often used to treat: Extensive wounding or trauma Burns Areas of extensive skin loss due to infection such as necrotizing fasciitis or purpura fulminans[2] Specific surgeries that may require skin grafts for healing to occur - most commonly removal of skin cancers Skin grafts are often employed after serious injuries when some of the body's skin is damaged. Surgical removal (excision or debridement) of the damaged skin is followed by skin grafting. The grafting serves two purposes: reduce the course of treatment needed (and time in the hospital), and improve the function and appearance of the area of the body which receives the skin graft.
Abdominal aortic aneurysms can weaken the aorta, your body’s largest blood vessel. This can develop into a potentially serious heath problem that can be fatal if the aneurysm bursts, causing massive internal bleeding. Endovascular stent grafting, or endovascular aneurysm repair (EVAR), is a newer form of treatment for abdominal aortic aneurysm that is less invasive than open surgery. Endovascular stent grafting uses an endovascular stent graft to reinforce the wall of the aorta and to help keep the damaged area from rupturing.
Embryonic cardiovascular system. ... The human arterial and venous systems develop from different embryonic areas. Aortic Arches. The aortic arches—or pharyngeal arch arteries—are a series of six, paired, embryological vascular structures that give rise to several major arteries .
Lipomas are slow-growing soft tissue tumours that rarely reach a size larger than 2 cm. Lesions larger than 5 cm, so-called giant lipomas, can occur anywhere in the body but are seldom found in the upper extremities. The authors present their experiences with eight patients having giant lipomas of the upper extremity. In addition, a review of the literature, and a discussion of the appropriate evaluation and management are included.
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.
The primary functions of the liver are: Bile production and excretion. Excretion of bilirubin, cholesterol, hormones, and drugs. Metabolism of fats, proteins, and carbohydrates. Enzyme activation. Storage of glycogen, vitamins, and minerals. Synthesis of plasma proteins, such as albumin, and clotting factors.
Frostbite is an injury caused by freezing of the skin and underlying tissues. First your skin becomes very cold and red, then numb, hard and pale. Frostbite is most common on the fingers, toes, nose, ears, cheeks and chin. Exposed skin in cold, windy weather is most vulnerable to frostbite. But frostbite can occur on skin covered by gloves or other clothing. Frostnip, the first stage of frostbite, doesn't cause permanent skin damage. You can treat very mild frostbite with first-aid measures, including rewarming your skin. All other frostbite requires medical attention because it can damage skin, tissues, muscle and bones. Possible complications of severe frostbite include infection and nerve damage.
The heart itself is made up of 4 chambers, 2 atria and 2 ventricles. De-oxygenated blood returns to the right side of the heart via the venous circulation. It is pumped into the right ventricle and then to the lungs where carbon dioxide is released and oxygen is absorbed. The oxygenated blood then travels back to the left side of the heart into the left atria, then into the left ventricle from where it is pumped into the aorta and arterial circulation.

Anytime you're having unprotected sex, there's always a chance that a woman can get pregnant. Pregnancy requires sperm and egg to meet up together so a woman needs to be during her most fertile time of the month, which is usually 6 days out of the month; 5 days leading up to ovulation and on the day of ovulation. For most women, ovulation happens 12-16 days before her period's going to start. So a woman is usually most fertile for a week to a week and a half after her period has ended generally speaking, if you don't want to count each and every single day. So if you have unprotected intercourse during this time, then there's a high probability that a woman can get pregnant. Now, you mentioned that your girlfriend is supposed to start her period in about five days or so. If you've had intercourse any time leading up to this, there's always a chance that she could get pregnant. But as for the mechanics of it all, in order to get pregnant, semen needs to be inserted inside the vaginal canal where the egg and sperm can then meet. So if that did not happen, then the chances of her getting pregnant are slim. But if that has happened, the chances of her getting pregnant are great. So it would be best for you and her to just wait until her period is supposed to start and if she's late, then take an over-the-counter pregnancy test and if it's positive, congratulations to both of you! If it's negative and she still doesn't start her period, then tell her to wait about 5-7 days. Take another test and then maybe at that point, it will be positive if she is indeed pregnant. If she continues to not have a period or she's concerned about anything, it would be best for her to follow up with her doctor and they can decide if further investigation or treatment is warranted.
