Answer:
The heart has four chambers — two upper chambers (called atria) and two lower chambers (ventricles). The heart has valves that temporarily close to permit blood flow in only one direction. The valves are located between the atria and ventricles, and between the ventricles and the major arteries from the heart.
Normal heart sounds are called S1 and S2. They are the “lubb-dupp” sounds that are thought of as the heartbeat. These sounds are produced when the heart valves close.
Because the heart is also divided into a right side and a left side, sometimes these sounds may be somewhat divided — most commonly noted is a split S2, caused when the right and left ventricles contract at very slightly different times. This is normal, but occasionally the nature of the split can indicate an abnormality such as enlargement of one of the ventricles.
Murmurs are blowing, whooshing, or rasping sounds. They are the result of vibrations caused by turbulent blood flow patterns. This can happen when a valve does not close tightly (such as with mitral regurgitation), or when the blood is flowing through a narrowed opening or a stiff valve (such as with aortic stenosis).

WRITING: PRINCIPLES OF CARBOHYDRATE LOADING
Write a 300-500 word essay. Explain the purpose of carbohydrate loading. What benefit is it in terms of performance? Give examples of when carbohydrate loading is appropriate and for approximately how long. Give a sample diet for one day of carbohydrate loading; portions are not needed. The emphasis is on food choices. Include three meals and two snacks.
Explanation:
Definition
A carbohydrate-loading diet, also called a carb-loading diet, is a strategy to improve your athletic performance for endurance events by increasing the amount of fuel stored in your muscles.
Carbohydrate loading occurs when you eat a high-carbohydrate "training diet" at the same time that you scale back your activity level in the days before an event.

Purpose
Any physical activity requires carbohydrates for fuel. For most recreational activity, your body uses its existing energy stores for fuel.
But when you engage in long, intense athletic events, your body needs extra energy to keep going. The purpose of carbohydrate loading is to give you the energy you need to complete an endurance event with less fatigue, improving your athletic performance.
Carbohydrate loading may be most beneficial if you're an endurance athlete — such as a marathon runner, swimmer, cyclist or all three — preparing for an event that will last 90 minutes or more. Other athletes generally don't need carbohydrate loading. It's usually enough to get about half of your calories from carbohydrates.
Diet details
The role of carbohydrates
Carbohydrates, also known as starches and sugars, are your body's main energy source. Complex carbohydrates include legumes, grains and starchy vegetables, such as potatoes, peas and corn. Simple carbohydrates are found mainly in fruits and milk, as well as in foods made with sugar, such as candy and other sweets.
During digestion, your body breaks down carbohydrates into sugar. The sugar enters your bloodstream, where it's then transferred to individual cells to provide energy. Sugar is stored in your liver and muscles as glycogen — your energy source.
Increase your energy storage
Your muscles normally store only small amounts of glycogen — enough to support you during recreational exercise activities. If you exercise intensely for more than 90 minutes, your muscles may run out of glycogen. At that point, fatigue might set in, and your performance may suffer.
But with carbohydrate loading, you may be able to store more energy in your muscles. This may give you the stamina to make it through longer endurance events. But, you'll still need to consume some energy sources during your event.
Carbohydrate loading
Carbohydrate loading is done the week before a high-endurance activity. One to three days before the event, increase your carbohydrate intake to about 8 to 12 grams of carbohydrate per kilogram of body weight. Cut back on foods higher in fat to compensate for the extra carbohydrate-rich foods.
Also scale back your training for three to four days before the event. The combination of eating more carbohydrates and tapering activity appear to boost muscle glycogen stores.
How many carbs you need depends on your total calorie goal as well as your sport. For most athletes, 5 to 7 grams of carbohydrate per kilogram of body weight daily is right for general training. (Note that 1 kilogram equals 2.2 pounds.) Endurance athletes may need up to 12 grams per kilogram.

Write a Paragraph on who started the first blood Bank/history
Answer:
One of the soonest blood donation centers was set up by Frederic Durán-Jordà during the Spanish Civil War in 1936. Duran joined the Transfusion Service at the Barcelona Hospital toward the beginning of the contention, however the clinic was before long overpowered by the interest for blood and the lack of accessible benefactors. With help from the Department of Health of the Spanish Republican Army, Duran set up a blood donation center for the utilization of injured officers and regular folks. The 300–400 ml of separated blood was blended in with 10% citrate arrangement in an altered Duran Erlenmeyer jar. The blood was put away in a sterile glass encased under tension at 2 °C. During 30 months of work, the Transfusion Service of Barcelona enrolled just about 30,000 givers, and handled 9,000 liters of blood.

This is the song "Dear parents" By Tate Mcrae. Now while I may not be 16...I can relate to so much of this song. Who else can? This is the full song btw for others asking.
"16, lot on her mind
Gotta few friends, left the rest behind
But guess that's just what happens, people change
Stressed out but is always "fine"
They be asking, but she can't describe
Maybe, they're right, it'll all be fixed with age
[Pre-Chorus]
Ha.te that you've been saying I'm dramatic
Immature because I just don't wanna talk
You ever think that you might be overre.acting?
Promise I'm thinking, overthinking quite a lot
[Chorus]
They say we're cra.zy and us.eless, making s.tupid excuses
To go make bad decisions when we're hurt
And we're not cr.azy rom.antics but we still know what a heart is
And know that when it's cracked it really burns
[Post-Chorus]
Oh we know more than what we tell you
But can't always put into words
And we don't cry because we want to
But you'll assume it's because she's another 16 year old girl
[Verse 2]
High school's been a terrifying one
She thinks she won't ever find someone
To build her back when she's in pieces and pieces again
Let's not forget about all the
One's who go and run their mouths just to
Stay relevant and not miss out
[Pre-Chorus]
Hate that you've been saying I'm dr.amatic
Immat.ure because I just don't wanna talk
You ever think that you might be overr.eacting?
Promise I'm thinking, overt.hinking quite a lot
[Chorus]
They say we're cr.azy and usele.ss, making st.upid ex.cuses
To go make bad decisions when we're hurt
And we're not crazy roma.ntics but we still know what a heart is
And know that when it's cracked it really burns
[Post-Chorus]
Oh we know more than what we tell you
But can't always put into words
And we don't cry because we want to
But you'll assume it's because she's another 16 year old girl"
