Article: Around a quarter of the human body cells are red blood cells, or erythrocytes. These RBCs are developed in the bone marrow produced at approximately 2.4 million red blood cells per second. Erythrocytes circulate in the body for 100 to 120 days. It is the same reason why we can only donate blood once every 3 to 4 months. Men have an average of 5.2 million RBCs per cubic millimeter meanwhile 4.6 million in women. If you are a regular blood donor, you'll notice that there are more men who passed the blood donation screening than women. The iron-rich protein known as hemoglobin is the main component of the red blood cells. It is responsible for the red color as iron binds with oxygen. Each hemoglobin molecule has four iron atoms and each of which binds to 1 oxygen molecule with 2 oxygen atoms. Around 33% of an erythrocyte is hemoglobin normally 15.5 g/dL in men and 14 g/dL in women. Red blood cells play an important role in transporting oxygen-rich blood from the lungs to the tissues and cells. RBCs have cell membranes composed of lipids and proteins essential for physiological function while working within the capillary network through the circulatory system. In addition, red blood cells aid in the removal of carbon dioxide. They contain the carbonic anhydrase enzyme which allows for a reaction of water and carbon dioxide to form carbonic acid and separate hydrogen and bicarbonate ions. Hydrogen ions bind with hemoglobin while bicarbonate ions go to the plasma removing approximately 70% of carbon dioxide. Twenty percent of carbon dioxide binds with hemoglobin which then released in the lungs. Meanwhile, the remaining 7% gets dissolved in the plasma.

Know the basics of red blood cells. Know how hemoglobin works in the blood. Understand the role of red blood cells.
Article: At the beginning of a group meeting, you should briefly introduce the interpreter by saying, "This is [name] and she will be the interpreter for today." This will let everyone know what the interpreter's role is in the room and acknowledge her presence for the deaf person. You may then want to allow the deaf person to introduce herself to the group, using the interpreter. If you are meeting the deaf person one-on-one with an interpreter, you should introduce yourself to the deaf person, not the interpreter. Face the deaf person and speak slowly and clearly. Most deaf people can read lips, but the deaf person may also have the interpreter sign your name. The deaf person may also introduce their interpreter to you, but you should avoid addressing the interpreter directly. Interpreters are there to facilitate, not participate, in the conversation. Make sure you are standing in a spot where the interpreter can be seen by the deaf person. Do not stand between or in the sightline of the interpreter and the deaf person. You may ask the interpreter where they would like you to stand or have the interpreter stand to the side of you in their chosen spot. The deaf person may also prefer to sit in the front of the room, close to the interpreter, so she can see the interpreter clearly during the meeting. You should start the group meeting by handing out any written materials right away as this will help the deaf person follow along and note anything if she misses the interpreter's signs. You may also want to create a clear itinerary for the meeting and hand it out so the deaf person is aware of what is going to be discussed. Remember the interpreter is not part of the conversation you are having with the deaf person and is not allowed to voice any personal opinions or enter the conversation. You should make eye contact with the deaf person and position your body toward her. If the deaf person needs the interpreter to explain something, she will turn and ask the interpreter. Allow her to do this, rather than try to do it yourself. You should try to speak in your normal speed and your normal tone of voice. Try to not rush or stumble when you speak and project your voice so it can be heard. Take a breath between each sentence as this will allow the interpreter and the deaf person time to catch up with what you are saying. If you are reading a text out loud, speak slowly and clearly. Avoid shouting or yelling, as this will not make it easier for the interpreter to sign to the deaf person and can be considered rude or inappropriate. Remember that there will be a slight lag as the interpreter signs to the deaf person. Keep this lag in mind as you speak and be patient as the interpreter finishes signing your words to the deaf person before moving on to your next sentence or thought. This lag will usually be a few words behind your speech. Allow for time for the interpreter to finish so the deaf person can respond and participate in the discussion. If the interpreter is confused or unclear about what you are saying, she may ask you to repeat your statement or ask questions about your statement for clarity. Answer her questions patiently and promptly to keep the conversation flowing for the deaf person. It can be confusing and overwhelming for the interpreter when more than one person is speaking at a time. In a group meeting setting, have everyone speak one at a time or take turns speaking around the room. You may also want to give the floor to one person at a time so the interpreter can focus on that person. You should make sure there is a brief pause between speakers so the interpreter has time to finish signing to the deaf person. This pause can also allow the deaf person to collect her thoughts and respond to the speaker. Avoid talking over someone else or interrupting someone during the meeting, as this can throw off the interpreter and make it more difficult for you to communicate effectively with the deaf person.

Introduce the interpreter. Position yourself out of the sightline of the interpreter and the deaf person. Pass out any written materials at the beginning of the meeting. Speak directly to the deaf person, not to the interpreter. Talk in your normal speed and tone. Wait patiently while the interpreter communicates your words to the deaf person. Have only one person speak at a time.
Article: It's summertime, so there is almost always an abundance of fresh fruit and vegetables. Pick your own - it'll taste the sweetest you've ever had. (Just be sure to know exactly what you are picking, and don't get anything poisonous.) Insect bites and sunburn can make your trip miserable. If this is a group trip, the sponsor or organizers should have this covered, but for a trip with family or friends, you may have to supply your own. Pack some antibiotic ointment, allergy medication, band aids, and toilet paper in it, at least. Don't forget bandages and tubi griped
