For many of these measurements the chest must be opened, but the blood vessels and the heart itself remain undisturbed.

Because the body contains so much liquid, transmission of ultrasonic signals proceeds fairly well in muscles and blood vessels.

A fearful pain had come from his head, as if the water were coursing up through the blood vessels and expanding them.

On contraction, these alternately pass the blood to a single ventricle which pumps it both into both the systemic vessels ( which service the body at large ) as well as the pulmonic vessels ( which return to the lungs for oxygenation ).

While there he collaborated with American physician Charles Claude Guthrie in work on vascular suture and the transplantation of blood vessels and organs as well as the head, and Carrel was awarded the 1912 Nobel Prize in Physiology or Medicine for these efforts.

This left a deep impression on Carrel, and he set about developing new techniques for suturing blood vessels.

The thickness of the aorta encourages an extensive network of tiny blood vessels called vasa vasorum, which feed the outer layers of the aorta.

Aortic pressure is highest at the aorta and becomes less pulsatile and lower pressure as blood vessels divide into arteries, arterioles, and capillaries such that flow is slow and smooth for gases and nutrient exchange.

Originally synthesized from compounds found in pit viper venom, ACE inhibitors inhibit angiotensin-converting enzyme ( a component of the blood pressure-regulating renin-angiotensin system ), thereby decreasing the tension of blood vessels and blood volume, thus lowering blood pressure.

Angiotensin II is found in the pulmonary circulation, as well as in the endothelium of many blood vessels.

The system in general aims to increase blood pressure by increasing the amount of salt and water the body retains, although angiotensin is also very good at causing the blood vessels to tighten ( a potent vasoconstrictor ).

* Vasoconstriction ( narrowing of blood vessels ) and vascular smooth muscle hypertrophy ( enlargement ) induced by AII may lead to increased blood pressure and hypertension.

In the US, the majority of new amputations occur due to complications of the vascular system ( the blood vessels ), especially from diabetes.

The resulting tangle of blood vessels, often called a nidus ( Latin for " nest ") has no capillaries and abnormally direct connections between high-pressure arteries and low-pressure veins.

Blood is circulated around the body through blood vessels by the pumping action of the heart.

Whole blood ( plasma and cells ) exhibits non-Newtonian fluid dynamics ; its flow properties are adapted to flow effectively through tiny capillary blood vessels with less resistance than plasma by itself.

Other types of tissue found in bones include marrow, endosteum, periosteum, nerves, blood vessels and cartilage.

Filling the interior of the bone is the trabecular bone tissue ( an open cell porous network also called cancellous or spongy bone ), which is composed of a network of rod-and plate-like elements that make the overall organ lighter and allow room for blood vessels and marrow.

Two problems present themselves in considering any hormone in blood.

Although variations of the blood supply to the adrenal glands ( and indeed the kidneys themselves ) are common, there are usually three arteries that supply each adrenal gland:

Plasma, which constitutes 55 % of blood fluid, is mostly water ( 92 % by volume ), and contains dissipated proteins, glucose, mineral ions, hormones, carbon dioxide ( plasma being the main medium for excretory product transportation ), and blood cells themselves.

Let them be thousands, let them drown themselves in their own blood.

They were joined by blood and marriage ; Diocletian and Maximian now styled themselves as brothers.

On one hand they act as immunodepressors, and protect the embryo from the immune system of the mother and on the other hand viral fusion proteins cause the formation of the placental syncytium in order to limit the exchange of migratory cells between the developing embryo and the body of the mother, where an epithelium won't do because certain blood cells are specialized to be able to insert themselves between adjacent epithelial cells.

They respond by cutting themselves and adding their own blood to the sacrifice ( such mutilation of the body was strictly forbidden in the Mosaic law ).

Often, this initial crack is caused by an increase in blood pressure within the body ( in combination with movement ), forcing an expansion across its exoskeleton, leading to an eventual crack that allows for certain organisms such as spiders to extricate themselves.

For most practical purposes, the brain is dependent on a continual supply of glucose diffusing from the blood into the interstitial tissue within the central nervous system and into the neurons themselves.

The heart did not pump blood around, the heart's motion sucked blood in during diastole and the blood moved by the pulsation of the arteries themselves.

Brocardus described them as " devils " and " secret murderers " who " sell themselves and are thirsty for blood ".

E. P. Thompson notes that for British workers at the end of the 18th and beginning of the 19th centuries, the " gap in status between a ' servant ,' a hired wage-laborer subject to the orders and discipline of the master, and an artisan, who might ' come and go ' as he pleased, was wide enough for men to shed blood rather than allow themselves to be pushed from one side to the other.

At the turn of the 18th to 19th century, nation-states commonly divided themselves between those granting nationality on the grounds of jus soli ( France, for example ) and those granting it on the grounds of jus sanguinis ( right of blood ) ( Germany, for example, before 1990 ).

This can also be seen in the Jewish case: as they accused others in the Near East of child sacrifice, they themselves would come to be accused of it in blood libel cases.

Those who measure their glucose levels themselves may notice hyperglycemia ( high blood sugar levels ).

The heart did not pump blood around, the heart's motion sucked blood in during diastole and the blood moved by the pulsation of the arteries themselves.

Symptomatic carriers of the gene, while not hemophiliacs themselves, can have symptoms of hemophilia including a lower than normal blood clotting factor that can lead to heavy bleeding.

Symptomatic carriers of the gene, while not hemophiliacs themselves, can have symptoms of hemophilia including a lower than normal blood clotting factor that can lead to heavy bleeding.

If I even hint at it do you think it will matter that you are his nephew -- and not even a blood nephew ''??

Theoretically, they are capable of extracting their required oxygen either from the surrounding air ( Ghoreyeb and Karsner, '13 ) or from pulmonary arterial blood ( Comroe, '58 ).

Some hymens are so strongly developed that they cannot be torn without considerable pain to the girl and marked loss of blood.

Before the dust has settled or the blood congealed, editorials, speeches, and civil-rights commissions are loud in the land, demanding to know what happened.

Readings of the number of milligrams of cholesterol in the blood, which seem to have value in predicting heart attacks, are becoming as routine as the electrocardiogram, which can show that the heart has suffered a symptomatic attack.

Although the fatty protein molecules, carried in the blood and partly composed of cholesterol, are water soluble, cholesterol itself is insoluble, and cannot be destroyed by the body.

In the juvenile ( or tadpole ) stage, gills are used to oxygenate blood and the circulation is similar to that of fish.

Since amphibians are cold-blooded, they must find ways to keep their blood at a constant temperature to maintain homeostasis.

The lungs in amphibians are primitive compared to those of amniotes, possessing few internal septa and large alveoli and consequently having a comparatively slow diffusion rate for oxygen entering the blood.

Giant salamanders of the genus Andrias, as well as Ceratophrine and Pyxicephalus frogs possess sharp teeth and are capable of drawing blood with a defensive bite.

As the body prepares to deal with a threat, blood pressure, heart rate, perspiration, blood flow to the major muscle groups are increased, while immune and digestive functions are inhibited ( the fight or flight response ).

For example the standard glutamic acid ( glutamate ) and the non-standard gamma-amino acid gamma-amino-butyric acid ( GABA ) are respectively the brain's main excitatory and inhibitory neurotransmitters, hydroxyproline-a major component of the connective tissue collagen-is synthesised from proline, the standard amino acid glycine is used to synthesise porphyrins used in red blood cells, and the non-standard carnitine is used in lipid transport.

Likewise a popular Hindu ritual form of worship of North Malabar in Kerala, India is the Tabuh Rah blood offering to Theyyam gods, despite being forbidden in the Vedic philosophy of sattvic Hinduism, Jainism and Buddhism, Theyyam deities are propitiated through the cock sacrifice where the religious cockfight is a religious exercise of offering blood to the Theyyam gods.

# The adeleorins are one-host parasites of invertebrates or vertebrates, or two-host parasites that alternately infect haematophagous ( blood-feeding ) invertebrates and the blood of vertebrates.

# Haemospororins often known as the malaria parasites, are two-host Apicomplexa that parasitize blood-feeding dipteran fies and the blood of various tetrapod vertebrates.

Microgametes and macrogametes are always found in the blood.

The gametes are taken up by the insect vector during a blood meal.

Chorizo ( pork sausage ), morcilla ( blood sausage ), chinchulines ( chitterlings ), mollejas ( sweetbread ), and other parts of the animal are enjoyed.

It entails manifold types of meat, which are generally eaten as follows: achuras ( offal, or the cow's inner parts ), morcilla ( blood sausage ,) and sometimes also a provoleta ( a piece of provolone cheese cooked on the grill with oregano ) are eaten first.
