August Krogh Quotes

I have often endeavoured to view the circulation of the blood in terrestrial animals, but without success, by reason that no parts of their bodies were sufficiently transparent.

With each beat, the heart pumps nearly three ounces of blood into the arteries--seventy-five to ninety gallons an hour when the body is at rest.

In many organisms, including man, the mechanical respiration and the circulation of the blood are 'regulated' so as to correspond to the demand of the moment.

The circulatory system of man and the vertebrate animals can be considered as made up of a small number of organs or subordinate systems, which are easy to recognize anatomically, and the functions of which are on the whole quite distinct.

If we now plainly perceive that the passage of the blood from the arteries into the veins of the tadpole is not performed in any other than those vessels, which are so minute as only to admit the passage of a single globule at a time, we may conclude that the same is performed in like manner in our own bodies and in those of other animals.

The arteries are found in nearly every part of the animal body, with the exception of the hairs, nails, and epidermis; and the larger trunks usually occupy the most protected situations, running, in the limbs, along the flexor side, where they are less exposed to injury.

The heart of animals is the foundation of their life, the sovereign of everything within them, the sun of their microcosm, that upon which all growth depends, from which all power proceeds.

Blood circulated through her veins with the fluidity of a song that branched off into the most hidden areas of her body and returned to her heart, purified by love.

The human heart is like a ship on a stormy sea driven about by winds blowing from all four corners of heaven.

This organ deserves to be styled the starting point of life and the sun of our microcosm just as much as the sun deserves to be styled the heart of the world. For it is by the heart's vigorous beat that the blood is moved, perfected, activated, and protected from injury and coagulation. The heart is the tutelary deity of the body, the basis of life, the source of all things, carrying out its function of nourishing, warming, and activating body as a whole. But we shall more fittingly speak of these matters when we consider the final cause of this kind of movement.

Did you think that rats do not have hearts? Wrong. All living things have a heart. And the heart of any living thing can be broken.

If you consume too much salt, it can cause water retention. When this happens, your body usually responds by raising your blood pressure to push excess fluid and salt out of your system.

Nitric oxide is a key biological messenger within the body. When released by the cells lining your arteries, it makes the walls of the arteries relax, allowing more blood to flow.

The cat is classic whilst the dog is Gothic - nowhere in the animal world can we discover such really Hellenic perfection of form, with anatomy adapted to function, as in the felidae.

Biological anthropology tends to focus on skeletons because that's what is often left behind in the ground, but I am a whole-body anatomist, I'm a clinical anatomist and that's what I teach, I teach it all, not just the skeleton, the muscles and nerves, blood vessels.

Every animal is related to its own constitution and the consciousness of it.

Just like the bones and muscles, the heart is designed to work in one gravity here on Earth, so when you put the heart in space, it operates differently and changes shape.

I believe that the power which the spleen possesses of regulating its amount of blood depends entirely upon mechanical properties.

The heart is the household divinity which, discharging its function, nourishes, cherishes, quickens the whole body, and is indeed the foundation of life, the source of all action.

The human heart is not unchanging (nay, changes almost out of recognition in the twinkling of an eye).

The human heart has hidden treasures, In secret kept, in silence sealed.

[T]he heart is like any other organ, you can weigh it on a scale.

Could she smell my breath? Could she hear my cursed circular heart beat revolving like the crime it is in my deathly chest?

The human heart: its expansions and contractions its electrics and hydraulics the warm tides that move and fill it. For years Art had studied it from a safe distance from many perspectives...he listened in fascination and revulsion, in envy and pity. He dispensed canned wisdom, a little scripture. He sent them on their way with a prayer.

The heart is everywhere, and each part of the organism is only the specialized force of the heart itself.
