Blood type (or blood group) is determined, in part, by the ABO blood group antigens present on red blood cells. A blood type (also called a blood group) is a classification of blood based on the presence or absence of inherited antigenic substances on the surface of red blood cells (RBCs).

A ventricular septal defect (VSD) is an opening or hole in the wall that separates the two lower chambers of the heart. This wall is called the ventricular septum. The hole causes oxygen-rich blood to leak from the left side of the heart to the right side. This causes extra work for the right side of the heart, since more blood than necessary is flowing through the right ventricle to the lungs. The hole is usually closed with surgery. However, in certain situations, your child's cardiologist and surgeon may think it is best to close the hole with a special device. This procedure is done in the heart catheterization lab.

The pain of ovulation can range from a mild twinge to severe discomfort and usually lasts from minutes to hours. It is generally felt on one side of the abdomen and may vary each month, depending on which ovary is releasing the egg during that cycle.

Cancer, also called malignancy, is an abnormal growth of cells. There are more than 100 types of cancer, including breast cancer, skin cancer, lung cancer, colon cancer, prostate cancer, and lymphoma. Symptoms vary depending on the type. Cancer treatment may include chemotherapy, radiation, and/or surgery.

Such foods include carrots, eggplant, cauliflower, green beans, broccoli, peppers, onions, lettuce, zucchini, tomatoes, peanuts and walnuts. These foods are generally safe for you to eat at each meal without spiking your blood sugar.

The eyes A close up of a young person's eyes. The eyes are responsible for four-fifths of all the information our brain receives. Here you can find out a bit more about how they work, common problems that affect vision and the work Sightsavers does to treat and prevent avoidable blindness. You can also find out more about the people whose lives have been changed thanks to donations from people like you. How do eyes work? (click image to see enlarged version or click here for text alternative) Graphic of an eye with information about its different parts The images we see are made up of light reflected from the objects we look at. This light enters the eye through the cornea. Because this part of the eye is curved, it bends the light, creating an upside down image on the retina (this is eventually put the right way up by the brain). The retina is a complex part of the eye, but only the very back of it is light sensitive. This part of the retina has roughly the area of a 10p coin, and is packed with photosensitive cells called rods and cones. Cones are the cells responsible for daylight vision. There are three kinds – each responding to a different wavelength of light: red, green and blue. The cones allow us to see images in colour and detail. Rods are responsible for night vision. They are sensitive to light but not to colour. In darkness, the cones do not function at all. How do we see an image? The lens focuses the image. It can do this because it is adjustable – using muscles to change shape and help us focus on objects at different distances. The automatic focusing of the lens is a reflex response and is not controlled by the brain. Once the image is clearly focused on the sensitive part of the retina, energy in the light that makes up that image creates an electrical signal. Nerve impulses can then carry information about that image to the brain through the optic nerve.

Hemoglobin is the protein molecule in red blood cells that carries oxygen from the lungs to the body's tissues and returns carbon dioxide from the tissues back to the lungs. Hemoglobin is made up of four protein molecules (globulin chains) that are connected together.

The term trisomy is used to describe the presence of three chromosomes, rather than the usual matched pair of chromosomes. For example, if a baby is born with three #21 chromosomes, rather than the usual pair, then the baby would be said to have "trisomy 21." Trisomy 21 is also known as Down syndrome. Other examples of trisomy include syndromes like trisomy 18 and trisomy 13. Again, trisomy 18 or trisomy 13 simply means the child has three copies of the #18 chromosome (or of the #13 chromosome) present in each cell of the body, rather than the usual pair.

What Happens When You're In a Coma?

The average human digestive tract is home to as many as 1,000 species of microorganisms. Most of them are harmless -- or even helpful -- under normal circumstances. But when something upsets the balance of these organisms in your gut, otherwise harmless bacteria can grow out of control and make you sick. One of the worst offenders is a bacterium called Clostridium difficile(C. difficile, or C. diff). As the bacteria overgrow they release toxins that attack the lining of the intestines, causing a condition called Clostridium difficilecolitis.

Comas are caused by an injury to the brain. Brain injury can be due to increased pressure, bleeding, loss of oxygen, or buildup of toxins. The injury can be temporary and reversible. It also can be permanent.

The spine is made flexible by discs located between each vertebra and ligaments made of tough elastic fibers which hold the vertebrae together. The spine gives the body stability and protects the spinal cord which is located in a narrow canal that runs through the center of each vertebra.

Like a fine whiskey barrel and wine cellar, cannabis also comes at its best when aged in a dark, cool place. Though there is no steadfast expiration date for cannabis, the method you use for preserving the cannabis makes a big difference in maintaining the buds’ freshness and potency. The question is, how do you store cannabis in a way that could extend its longevity while maintaining the vigor and freshness? Experts have described different methods. However, here are some time-proven methods that are easy and inexpensive and require very less equipment. Use air-tight glass containers to store the weed Use clean air-tight glass containers or jars to store cannabis. You can buy glass containers from any ordinary supermarket or hardware store. The tricky part is to make sure you do leave some air in the container while the air stored with cannabis isn’t in detrimental extent. Always leave 1/4 space at the top of the canister or container. Do not fill the containers to the brim with the buds. If you leave no air, then the buds will dry out. If you have too much air, the buds will get damp and moldy. Freeze your cannabis in a convenient temperature The best way to store your buds is in air-tight glass jars, in a cool and dark place under an ideal temperature between 60 and 70 degrees Fahrenheit. If you need to store a high volume of cannabis, you can freeze them after keeping them completely dry for a period of 4 weeks. On this note, you should know that you must not handle frozen buds until it becomes normal in room temperature as trichomes become brittle and can easily break off in freezing temperature. Refrigerate your cannabis (Not Recommended) Even if you use airtight jars, cannabis can grow mold in the fridge. So, you should avoid storing cannabis in the fridge. If you can’t help but doing it, make sure the weed is completely dry and put them in the back where the humidity and temperature don’t fluctuate. Plastic Baggies (Worst method!) Albeit this is very common among people who aren’t expert in handling cannabis, this is the worst of all storage methods. Cannabis gets brittle and dries out in plastic bags. It also loses its natural smell, and the potency deteriorates sharply. So, it should be avoided entirely or can be used for a short-term if there is no better alternative. Here are some things you should know while storing cannabis - Make sure cannabis has been cured for at least 4 weeks before putting them into long-term storage. Without proper curing before storage, the buds can lose their strength and smoothness. - Sunlight can stop the medicinal qualities of cannabis. Your cannabis, if stored correctly, can maintain its medicinal qualities for a few years. Exposure to Sun will turn your cannabis brown, no matter how you have stored it away. - Air-tight, nonporous glass jar are the best way for storing the buds for long term. You can use metal or plastic box/bag, but that could reduce the smell and taste after a while. - Avoid heat and middling temperature in the place where you store your buds. The ideal temperature is 60-70°F (15-21°C) or under 32°F (0°C). Extra heat, cold or middling temperature cause the cannabis potency to decrease. - Keep your cannabis away from any electronic devices or appliances that will expose the cannabis to heat. Keeping cannabis on top of a microwave, or near a laptop or mobile charge is a bad idea.
