Blood that comes from the left side of the heart is full of oxygen and nutrients. Nutrients are substances that your body needs to live, like protein, fat, carbohydrates, vitamins, and minerals. The blood brings the oxygen and nutrients to your body.
This blood in "systemic" arteries that is full of oxygen and nutrients is "systemic arterial blood". It is sometimes just called "arterial blood".
The biggest systemic artery in the body is the aorta. This is the large blood vessel that comes out of the heart. Smaller arteries branch off from the aorta. These arteries have smaller arteries that branch off from them. The smallest arteries turn into arterioles.
The smallest blood vessels are capillaries. Systemic arterioles turn into capillaries. The blood from arterioles goes into the capillaries. There oxygen and nutrients go out of the blood into the tissue around the capillaries. The blood also picks up carbon dioxide and waste from the tissue. The network of capillaries that brings blood to an area is called a "capillary bed".
On the other end of the capillary, it turns into a venule. Venules are the smallest veins. Veins take blood back to the heart. As veins go back to the heart, they merge and get bigger. The biggest systemic veins in the body are the vena cava. There are two vena cava. The "inferior vena cava" takes blood from the lower part of the body to the right side of the heart. (In anatomy, inferior means below.) The "superior vena cava" takes blood from the upper part of the body to the heart. (Superior means above.)
This same movement of blood goes through the lungs in the "pulmonary circulation".
The blood that the vena cava vein takes to the heart is full of carbon dioxide. It has much less oxygen than (systemic) arterial blood. The right side of the heart pushes the venous blood into the pulmonary artery. The pulmonary artery takes blood to the lungs. In the lungs, the blood goes through the "pulmonary capillary bed". (The capillaries that are in the lungs). Here it gets more oxygen. It also drops off carbon dioxide. (This is the opposite of what happens in capillary beds in the rest of the body. In the systemic circulation blood drops off oxygen and picks up carbon dioxide).
After the pulmonary capillary bed, the blood goes to the pulmonary veins. This "pulmonary venous blood" now is full of oxygen. The pulmonary veins take blood to the left side of the heart. Then the blood goes to the systemic circulation again.
Veins from the gut shunt to the liver before returning to the right atrium and ventricle. The shunt is called the hepatic portal vein.
The meaning of this is as follows. The liver is the body's main chemical factory. It takes in the flow of nutrients from the gut, and adjusts them to suit what the body needs. It can store surplus nutrients, or release extra nutrients from store. It can change the chemical make-up of many nutrients. In this way it adapts to the many different kinds of food which the body digests.
Pink triangle
The pink triangle is one of the two big symbols of the LGBT community. The other is the rainbow flag.
The pink triangle was first used in Nazi Germany to mark homosexual prisoners. There was also a "black triangle" that marked "anti-social women". Many but not all of these women were lesbians. Jews wore the famous yellow star of David. If a prisoner was both Jewish and gay, he would wear a yellow triangle overlapped by a pink triangle, creating a star of David.
Homosexuality was illegal in Nazi Germany under a law called "Paragraph 175", which made it a felony (a "very serious" crime). About 100,000 people were arrested, with about 50,000 sent to prison. Some were sent to mental hospitals. Some were castrated (had their testicles removed). Some homosexual men were also sent to concentration camps, especially Jewish homosexuals. Between 15,000 and 600,000 homosexual men were sent to concentration camps. Most of them died there. We are not sure of the real number. Prisoners who were Jewish and homosexual may not have been counted as homosexual.
Homosexual prisoners were treated worse than other prisoners. Their death rates were higher than other "anti-social" groups. One story by a gay man who lived in a concentration camp shows how it was. Pierre Seel was sent to the Schirmeck concentration camp. The Nazis said a public execution would happen. A man was brought out. Seel saw that the man was his 18 year old lover. The Nazis took all the clothes of Seel's lover and put a bucket over his head. Then Seel had to watch as the Nazis let German Shepherds (dogs) maul his lover to death.
After World War II, homosexual men were still not treated well in Germany. The law continued. It was used to hurt homosexuals and to put them in prison. Many spent years in prison.
The pink triangle observes the memory of the homosexual people who died in the Holocaust. It is important not to ignore these deaths. The killing of homosexuals both during WWII "and" "after" WWII ended is the secret story of the Holocaust. Using the pink triangle symbol puts these victims in the public view. It is in respect for those who died.
Chat room
A chat room is a virtual place on the Internet where people can get together and type messages to each other using text. People use programs like IRC to join a chat room and type messages or send pictures to the other people within that chat. There are also other programs called instant messengers to stay in contact with friends, colleagues and other people. Websites on the Internet often have types of chat rooms built into them, and lots of chat rooms also use .
Chat rooms are normally used as tools to talk with people that are far away, but many people still use them to talk to people who live near them, because it's very convenient.

Devil May Cry 4
Devil May Cry 4 is the fourth video game in the series of "Devil May Cry". It was released on the PlayStation 3 and Xbox 360 on February 5 2008. Before to this game, all "Devil May Cry" games had only been released on the PlayStation video game consoles. This one was the first game to be released on the Xbox as well as The PlayStation. In January, gamers could download a demo at the PlayStation Store and Xbox Live Marketplace .
One big difference in this game is that Dante is no longer the main character. A new character named Nero is the new hero. Lady and Trish from older games return in this game. This game has more new characters, such as Kyrie, Credo, Agnus, Gloria, and Sanctus and new demons and bosses for the player to fight.
This game is just like the first games. It follows the usual "Devil May Cry" gameplay using a variety of melee and long-range weapons
