Being too large, either in their perfect form, or in the egg, to have passed through the capillary blood-vessels, how came they within the body of another animal, itself but a few weeks or a few days old, or even in the embryo stage, unless they were created there without parentage of their own species?
Each villus contains a loop of blood-vessels, and another vessel, the lacteal, so called from the Latin word lac, milk, because of the milky appearance of the fluid it contains. The villi are adapted especially for the absorption of fat. They dip like the tiniest fingers into the chyle, and the minute particles of fat pass through their cellular covering and gain entrance to the lacteals.
Not only his chest pressed upon his lungs, but his lungs strained toward his backbone. Not only the flesh of his thighs tugged to flatten itself against his acceleration-chair, but the blood in his legs tried to flow into and burst the blood-vessels in the back of his legs. The six-gravity acceleration seemed to endure for centuries. Actually, it lasted for fourteen seconds.
Only one man in six dies of disease of the nervous system, as contrasted with nearly one in three from diseases of the lungs; and only one individual in four hundred becomes insane, as contrasted with from three to ten times that number whose digestive systems, whose locomotor apparatus, whose heart and blood-vessels become hopelessly deranged without actually killing them.
But for this, a very small cut might cause bleeding sufficient to empty the blood-vessels, and death would speedily follow. In slight cuts, Nature plugs up the wound with clots of blood, and thus prevents excessive bleeding. The unfavorable effects of the want of clotting are illustrated in some persons in whom bleeding from even the slightest wounds continues till life is in danger.
I think that she even took a malicious pleasure in the idea that she was very likely catching cold, and that her Cousin Robert was answerable for her danger. If she could have brought upon herself inflammation of the lungs, or ruptured blood-vessels, by that exposure to the chill March atmosphere, I think she would have felt a gloomy satisfaction in her sufferings.
The purpose of the gill slits is made more apparent by the presence in the embryo of gill arches of the blood-vessels, like those normal to the fish. These disappear in common with the slits.
This theory of lightning-photographs of neighboring objects on the skin has probably arisen from the resemblance of the burns due to the ramifications of the blood-vessels as conductors, or to peculiar electric movements which can be demonstrated by positive charges on lycopodium powder.
What symptoms are characteristic of pleurisy? Give the treatment for pleurisy. Give the causes and treatment of "heaves." GENERAL DISCUSSION. The circulatory organs are the heart, arteries, veins and lymphatics. Its function is to force the blood through the blood-vessels. It is situated in the thoracic cavity between the lungs, and enclosed by a special fold of the pleura, the pericardial sack.
On the other hand, in pyogenic infections in the substance of the liver, in the substance of the kidney, within the brain, in the retroperitoneal space, in the lobes of the lung, in the chambers of the heart and in the blood-vessels of the chest and the abdomen, in all locations in which muscular contractions can in no way assist in localizing the disease, pyogenic infections produce no muscular rigidity and no pain.
