|Vāyu is a primary Hindu deity, the Lord of the winds, the father of Bhima and the spiritual father of Lord Hanuman. He is also known as Vāta (वात), Pavana (पवन, the Purifier), and sometimes Prāṇa (प्राण, the breath)|

In front, it is separated from the anterior wall of the thorax, in the greater part of its extent, by the lungs and pleuræ; but a small area, somewhat variable in size, and usually corresponding with the left half of the lower portion of the body of the sternum and the medial ends of the cartilages of the fourth and fifth ribs of the left side, comes into direct relationship with the chest wall. The lower extremity of the thymus, in the child, is in contact with the front of the upper part of the pericardium. Behind, it rests upon the bronchi, the esophagus, the descending thoracic aorta, and the posterior part of the mediastinal surface of each lung. Laterally, it is covered by the pleuræ, and is in relation with the mediastinal surfaces of the lungs; the phrenic nerve, with its accompanying vessels, descends between the pericardium and pleura on either side".
"Dharana: Concentration is the process of holding or fixing the attention of mind onto one object or place. (3.1) (See also 1.30-1.32)
Dhyana: Meditation is sustained concentration, whereby the attention continues to hold or repeat the same object or place. (3.2)"
On the inhalation we can bring the breath to the heart and on the exhalation offer our bodies up to the same, attending to the effect and the image during retention(however we wish to imagine it, Vayu galloping through our veins on that deer thing perhaps).
..and that might work for you, until you get around to some old time, seriously old time, religion.
Alternatively, you can just say to heck with it, put all your preconceptions to one side, suspend disbelief, grant some artistic licence (as I certainly did most of the way through the movie Prometheus the other afternoon) and invite the gods in for a couple of hours every morning, just as you allow a movie to take you over, or the music at a concert, let the god(s) do the same and be done with it.
Interestingly the Krishnamacharya movie many of us are waiting for is called Breath of the Gods
and then there's this...
from Bread and Wine by Friedrich Holderlin
we pick it up a few verses in...
At first the gods come unperceived. Children try to get
Near them. But their glory dazzles and blinds and
Awakens fear. A demi-god scarcely knows the people
By name, who now approach him with gifts. But their
Courage is great. Their joy fills his heart, and he hardly
Knows what to do with the offerings. He busies himself
And becomes wasteful, and unholy things almost become holy,
Which he touches with a blessing hand, foolishly and kindly.
The gods tolerate it as long as they can, and then in truth
They appear themselves. And people become accustomed
To this fortune, to the daytime, and to the sight of the manifest
Ones, the faces of those formerly called the "One and All,"
Deeply making every silent breast content, and first and alone
Filling every desire. It's the way people are. When something
Good appears, and even when it's a god that provides them
With gifts, they don't see or recognize it. First they have
To get used to it; then they call it their closest possession.
And only then will words of praise arise, like flowers.
And now they prepare in earnest to honor the holy gods.
Everything must really and truly proclaim their praise.
Nothing displeasing to the high ones may come to light.
Idle endeavors aren't proper for the Aether.
Therefore, to stand worthily in the presence of the gods,
Nations rise in splendid order and beautiful
Temples and cities are built, strong and noble, which rise
Above the banks of the waters —but where are they?
Where are the famous, flourishing cities, crowning the festival?
Thebes and Athens are fading. Don't the weapons clash
At Olympus, or golden chariots at the games? Are there
No longer wreaths to decorate the ships of Corinth?
Why are the ancient holy theaters silent?
What happened to the joyful ceremonial dancing?
Why doesn't a god place his sign on a human forehead,
Leaving his mark on the person he has struck?
Or, as gods used to, come comfortingly, and assume human
Shape, then complete and close the festival of the gods?
But friend, we come too late. It's true that the gods live,
But up over our heads, up in a different world.
They function endlessly up there, and seem to care little
If we live or die, so much do they avoid us.
A weak vessel cannot hold them forever; humans can
Endure the fullness of the gods only at times. Therefore
Life itself becomes a dream about them. But perplexity
And sleep assist us: distress and night-time strengthen,
Until enough heroes have grown in the bronze cradle,
With hearts as strong as the gods', as it used to be.
Thundering they arise. Meanwhile I often think it is
Better to stay asleep, than to exist without companions,
Just waiting it out, not knowing what to do or say
In the meantime. What use are poets in times of need?
But you'll say they're like holy priests of the wine god,
Moving from land to land in the holy night.
Some time ago — to us it seems like a long time —
All those who made our lives happy climbed upwards.
The Father turned his face away from people,
And sorrow came rightly upon the earth.
Finally a quiet genius appeared, comforting in a god-like
Way, who announced the end of the day, and disappeared.
The choir of gods left some gifts behind, as a sign
Of their presence and eventual return, which we
May appreciate in our human fashion, as we used to.
That which is superior had grown too great for pleasure
With spirit among men. And to this day no one's strong enough
For the highest joys, although some gratitude survives quietly.
Bread is the fruit of the earth, yet it's blessed also by light.
The pleasure of wine comes from the thundering god.
We remember the gods thereby, those who were once
With us, and who'll return when the time is right.

How Blood Carries Oxygen
We all know that oxygen is the key to living. It's in the air you breathe, in your lungs and in your blood. What you might not know is how oxygen gets into your blood and how the blood carries oxygen through your body.
Blood and Oxygen - How It Works
You breathe air in through your nose and mouth. It makes its way into your lungs and dissolves in the water lining of the alveoli. Oxygen then clings to red blood cells as they pass through the alveolar capillaries - now the oxygen is in the blood.
Blood and Oxygen - Types of Blood Vessels
Three types of blood vessels carry blood from your lungs to every cell in your body.
Arteries - Arteries have muscular walls that pump oxygen-filled blood away from your heart to the tissues and organs, like the brain, kidneys and liver. Arteries get smaller as they get further from your heart. At their smallest point, arteries become capillaries.
Capillaries - Capillaries are the tiniest blood vessels. They connect arteries to veins.
Veins - Veins are what bring the "used" blood back to your heart.
