The heart is a muscular organ in humans and other animals, which pumps blood through the blood vessels of the circulatory system.^[1] Blood provides the body with oxygen and nutrients, and also assists in the removal ofmetabolic wastes.^[2] The heart is located in the middle compartment of the mediastinum in the chest.^[3]

In humans, other mammals and birds the heart is divided into four chambers: upper left and right atria; and lower left and right ventricles.^[4][5] Commonly the right atrium and ventricle are referred together as the right heart and their left counterparts as the left heart.^[6] Fish in contrast have two chambers, an atrium and a ventricle, while reptiles have three chambers.^[5] In a healthy heart blood flows one way through the heart due toheart valves, which prevent backflow.^[3] The heart is enclosed in a protective sac, the pericardium, which also contains a small amount of fluid. The wall of the heart is made up of three layers: epicardium; myocardium; and endocardium.^[7]

The heart pumps blood through both circulatory systems. Blood low in oxygen from the systemic circulation enters the right atrium from the superior and inferior vena cavae and passes to the right ventricle. From here it is pumped into the pulmonary circulation, through the lungs where it receives oxygen and gives off carbon dioxide. Oxygenated blood then returns to the left atrium, passes through the left ventricle and is pumped out through the aorta to the systemic circulation−where the oxygen is used and metabolized to carbon dioxide.^[2] In addition the blood carries nutrients from the liver and gastrointestinal tract to various organs of the body, while transporting waste to the liver and kidneys.^{[citation needed]} Normally with each heartbeat, the right ventricle pumps the same amount of blood into the lungs as the left ventricle pumps out into the body. Veins transport blood to the heart, while arteries transport blood away from the heart. Veins normally have lower pressures than arteries.^[2][3] The heart contracts at a rate of around 72 beats per minute, at rest.^[2] Exercise temporarily increases this rate, but lowers resting heart rate in the long term, and is good for heart health.^[8]

Cardiovascular diseases (CVD) were the most common cause of death globally in 2008, accounting for 30% of cases.^[9][10] Of these deaths more than three quarters were due to coronary artery disease and stroke.^[9] Risk factors include: smoking, being overweight, not enough exercise, high cholesterol, high blood pressure, and poorly controlled diabetes among others.^[11] Diagnosis of CVD is often done by listening to the heart-sounds with a stethoscope, ECG or by ultrasound.^[3] Diseases of the heart are primarily treated by cardiologists, although many specialties of medicine may be involved.^[10]

a poem

Remember

BY CHRISTINA ROSSETTI

Remember me when I am gone away,

         Gone far away into the silent land;

         When you can no more hold me by the hand,

Nor I half turn to go yet turning stay.

Remember me when no more day by day

         You tell me of our future that you plann'd:

         Only remember me; you understand

It will be late to counsel then or pray.

Yet if you should forget me for a while

         And afterwards remember, do not grieve:

         For if the darkness and corruption leave

         A vestige of the thoughts that once I had,

Better by far you should forget and smile

         Than that you should remember and be sad.

Blast from the past

This post was from my sister (Louis the Bear) when she was in the class in 2011.


Yes, I'm super jealous of her writing style.

I want to say it right.

When I was a kid, I went to the theatre a lot. Mom found a deal…where a theatre would show get this: 2-3 year old movies. Washed out washed up movies. You got a soda and some popcorn but it, the popcorn, always tasted like the cardboard box around it.

Once they were going to show Black Beauty. It was going to be better than the previous week’s “Little Vampire”. When we drove to that theatre it felt like driving to see Black Beauty.

When he wasn’t there, I stood on my chair. When the lady with the undulating voice told me to sit down I went to look at the tiles in the bathroom. They were the same green you always see.

What I mean to say is that….

Sometimes I would leave Smarties out for either Jesus or you. You were both close.

But I couldn’t see you. Who is the man that makes me feel things exactly? Where are his hands and is their space for me? I thought that you could hold on to me holding myself together. If I could find you.

I mean…..I mean….I mean that I saw you sleeping at the Grand Canyon. But only your spindles. And the good acts of men have shown me your backbone and when I came out those theatres walking as what the hour and a half was about I felt your footsteps.

But you never stay long enough, and only in my stomach. When life feels like living you’re there. And it is then that I look down and inside myself and I see you there. I see the top of your head and a glance of your elbow as you stir soup there. I’ve put you through long winters.

I mean…. I mean that he’s in the moments that feel like moments. I mean that he’s in staring out the window too long. In the chairs if you’ll just stand on them, in the runt of the liter stuck in the bag that doesn’t get tossed in the lake. In the words said right and the souls that sing for the other and the pretty violin that sounds like.

I’ve seen his ears, and heard his heart. Seen the back of his neck walking away. To know that face, reach out, hold onto it…. close.

I mean to say—don’t tell me. Don’t tell me how.
