Angels, in a variety of religions, are regarded as spirits. They are often depicted as messengers of God in the Hebrew and Christian Bibles and the Quran. The English word angel is derived from the Greek ἄγγελος (aggelos), a translation of מלאך (mal'akh) in the Hebrew Bible (Tanakh); a similar term, ملائكة (Malāīkah), is used in the Qur'an. The Hebrew and Greek words originally meant messenger, and depending on the context may refer either to a human messenger (possibly a prophet or priest, such as Malachi, "my messenger", but also for more mundane characters, as in the Greek superscription that the Book of Malachi was written "by the hand of his messenger" (ἀγγήλου)) or to a supernatural messenger, such as the "Mal'akh YHWH," who (depending on interpretation) is either a messenger from God, an aspect of God (such as the Logos), or God Himself as the messenger (the "theophanic angel.")
The term "angel" has also been expanded to various notions of spirits found in many other religious traditions. Other roles of angels include protecting and guiding human beings, and carrying out God's tasks.
The heart is a myogenic muscular organ found in all animals with a circulatory system (including all vertebrates), which pumps blood throughout the blood vessels by repeated, rhythmic contractions. The term cardiac (as in cardiology) means "related to the heart" and comes from the Greek καρδιά, kardia, for "heart".
The vertebrate heart is principally composed of cardiac muscle and connective tissue. Cardiac muscle is an involuntary striated muscle tissue found only in this organ and responsible for the ability of the heart to pump blood. The average human heart, beating at 72 beats per minute, will beat approximately 2.5 billion times during an average 66 year lifespan. It weighs approximately 250 to 300 grams (9 to 11 oz) in females and 300 to 350 grams (11 to 12 oz) in males.
In invertebrates that possess a circulatory system, the heart is typically a tube or small sac and pumps fluid that contains water and nutrients such as proteins, fats, and sugars. In insects, the "heart" is often called the dorsal tube and insect "blood" is almost always not oxygenated since they usually respirate (breathe) directly from their body surfaces (internal and external) to air. However, the hearts of some other arthropods (including spiders and crustaceans such as crabs and shrimp) and some other animals pump hemolymph, which contains the copper-based protein hemocyanin as an oxygen transporter similar to the iron-based hemoglobin in red blood cells found in vertebrates.
Angels, angels
They didn't want to be but suddenly they're free
Angels, angels
I hear them in the trees and I wish that one was me
I watch clouds roll overhead
No, it's me that moves instead
Round and round, and round
Clouds are faces I can see
I can see they're seein' me
I can tell 'cause we know each other well
We know each other well
Angels, angels
I hear them in the trees, I wish that one was me
Angels how high have you been?
Since you left this world I'm in
And what did you see 'bout me?
Will my time go very far?
Does love reach up where you are?
Then take it along, I pay you for your songs
Can I go? Can I go along?
Angels, angels
They didn't want to be but suddenly they're free
Angels, angels
I hear them in the trees and wish that one was me
I wish that one
