The paired Müllerian glands inside the male cloaca secrete a fluid which resembles that produced by mammalian prostate glands and which may transport and nourish the sperm.

Lumbar puncture procedure, which is performed in many infectious disorders of the central nervous system is contraindicated in this condition ( as it is in all space-occupying lesions of the brain ) because removing a certain portion of the cerebrospinal fluid may alter the concrete intracranial pressure balances and causes the brain tissue to move across structures within the skull ( brain herniation ).

This increase in glycerol has been postulated to be responsible for the lubricating quality of this fertile cervical fluid and may be biologically relevant during the early phase of reproductive events.

It may be a liquid ( LC and Capillary Electrochromatography ( CEC )), a gas ( GC ), or a supercritical fluid ( supercritical-fluid chromatography, SFC ).

Ten percent of a person's body weight in fluid may need to be given in the first two to four hours.

AVMs in certain critical locations may stop the circulation of the cerebrospinal fluid, causing accumulation of the fluid within the skull and giving rise to a clinical condition called hydrocephalus.

The mass is normally measured with an appropriate scale or balance ; the volume may be measured directly ( from the geometry of the object ) or by the displacement of a fluid.

Transport of material in stagnant fluid or across streamlines of a fluid in a laminar flow occurs by molecular diffusion. Two adjacent compartments, separated by partition containing pure gases A or B may be envisaged.

For example, it may go from having only periodic motions to apparently erratic behavior, as in the transition to turbulence of a fluid.

A heat engine may also serve as a prime mover, a component that transforms the flow or changes in pressure of a fluid into mechanical energy.

There are then two types of work performed: flow work described above, which is performed on the fluid ( this is also often called pV work ), and shaft work, which may be performed on some mechanical device.

Oversize particles may form a cake layer on top of the filter and may also block the filter lattice, preventing the fluid phase from crossing the filter ( blinding ).

Hall effect sensors are readily available from a number of different manufacturers, and may be used in various sensors such as rotating speed sensors ( bicycle wheels, gear-teeth, automotive speedometers, electronic ignition systems ), fluid flow sensors, current sensors, and pressure sensors.

Non-streamlined objects such as bluff bodies and flat plates may also generate lift when moving relative to the fluid, but will have a higher drag coefficient dominated by pressure drag.

In the industrial market place the specification may take the form of a legal contract to supply a conforming fluid or purchasers may choose to buy on the basis of a manufacturers own published specification.

Lubricant persistence in the environment largely depends upon the base fluid, however if very toxic additives are used they may negatively affect the persistence.

When a fluid is flowing through a closed channel such as a pipe or between two flat plates, either of two types of flow may occur depending on the velocity of the fluid: laminar flow or turbulent flow.

Symptoms may include severe fatigue, a heavy swollen limb or localized fluid accumulation in other body areas, including the head or neck, discoloration of the skin overlying the lymphedema, and eventually deformity ( elephantiasis ).

Otherwise, bodies may be semi-rigid, i. e. elastic, or non-rigid, i. e. fluid.

Piston-type gauges counterbalance the pressure of a fluid with a spring ( for example tire-pressure gauges of comparatively low accuracy ) or a solid weight, in which case it is known as a deadweight tester and may be used for calibration of other gauges.

Exposure to low levels of this chemical can irritate the eyes, cause a cough or sore throat, shortness of breath, and fluid accumulation in the lungs.

His eyes were dark, fluid, fearful, and he gave a sigh as my knife went in.

He recalled that the worst moments were being towed with fluid rushing up his nose and his eyes swelling up.

It lies on its side, mouth and eyes open, tongue hanging out, emitting a green fluid from its anus whose putrid odor repels predators.

He dissected the eyes of animals, and discovering three layers ( not two ), found that the fluid was of a constant consistency with the lens forming ( or congealing ) after death, and the surrounding layers were seen to be juxtaposed.

When " playing possum ", the animal's lips are drawn back, the teeth are bared, saliva foams around the mouth, the eyes close or half-close, and a foul-smelling fluid is secreted from the anal glands.

However, when the Master removes his sunglasses, revealing non-human eyes, the Doctor and Dr Holloway abandon the ambulance and steal a police motorcycle, but not before the Master is able to shoot Dr Holloway's wrist with a strange, bile-like fluid.

These may include jaundice ( yellow discolouration of the skin and the whites of the eyes ), ascites ( fluid accumulation in the abdominal cavity ), and peripheral edema ( swelling of the legs due to fluid build-up in the skin ).

These include floaters ( material floating in the eye fluid that appears as black / dark objects floating in front of the eyes and are particularly visible when looking at the bright sky or on a white wall ) and the white blood cells of the retinal blood vessels ( seen as tiny, fast-moving and quickly disappearing white specks ).

Yet this is a myth: Crocodiles possess lacrimal glands which secrete a proteinaceous fluid, just like in humans, though tears will only be visible after a crocodile is out of the water for a prolonged period of time, and the eyes begin to dry out.

Insertion of an NPA is contraindicated in patients with severe head or facial injuries, or have evidence of a basilar skull fracture ( Battle's sign, raccoon eyes, cerebrospinal fluid / blood from ears, etc.

Basilar fractures have characteristic signs: blood in the sinuses ; a clear fluid called cerebrospinal fluid ( CSF ) leaking from the nose ( rhinorrhea ) or ears ( otorrhea ); periorbital ecchymosis often called ' raccoon eyes ' ( bruising of the orbits of the eyes that result from blood collecting there as it leaks from the fracture site ); and retroauricular ecchymosis known as " Battle's sign " ( bruising over the mastoid process ).

He was known as the " weeping philosopher " and died of hydropsy, a swelling due to abnormal accumulation of fluid beneath the skin.

Care must be taken in giving these solutions because they can cause skin necrosis if the IV is infiltrated, sclerosis of veins, and many other fluid and electrolyte disturbances if administered incorrectly.

The lymph fluid has been found to move through a lymph capillary of the skin at approximately 0. 0000097 m / s.

# Control of evaporation: the skin provides a relatively dry and semi-impermeable barrier to fluid loss.

Various protective devices are used to avoid contact with blood, vaginal fluid, semen or other contaminant agents ( like skin, hair and shared objects ) during sexual activity.

Sharks have a covering of dermal denticles that protects their skin from damage and parasites in addition to improving their fluid dynamics.

By scratching the fluid from cowpox lesions into the skin of healthy individuals, he was able to immunize those people against smallpox.

* Bunion – A bump or bulge on the first joint of the big toe caused by the swelling of a sac of fluid under the skin.

* Subcutaneous injection – Putting a fluid into the tissue under the skin with a needle and syringe.

Oedema ( British English ) or edema ( American English ) (; from the Greek-oídēma, " swelling "), formerly known as dropsy or hydropsy, is an abnormal accumulation of fluid beneath the skin or in one or more cavities of the body that produces swelling.

Perspiration ( sweating, transpiration, or diaphoresis ) is the production of a fluid consisting primarily of water as well as various dissolved solids ( chiefly chlorides ), that is excreted by the sweat glands in the skin of mammals.

In " living donors ", the donor remains alive and donates a renewable tissue, cell, or fluid ( e. g. blood, skin ), or donates an organ or part of an organ in which the remaining organ can regenerate or take on the workload of the rest of the organ ( primarily single kidney donation, partial donation of liver, small bowel ).

The drag coefficient of any object comprises the effects of the two basic contributors to fluid dynamic drag: skin friction and form drag.

In the Book of Mormon, the labels “ Nephite ” and “ Lamanite ” ultimately became political terms of convenience, where membership was varied and fluid, and not based on skin color.

This shunt is usually inserted in between two of the vertebrae in the lumbar and punctures the cerebrospinal fluid sack or lumbar subarachnoid space, it then runs beneath the skin to the peritoneal cavity, where it is eventually drained away by the normal bodily fluid drainage system.

These inquiries together put the science of fluid dynamics on a new footing, and provided a key not only to the explanation of many natural phenomena, such as the suspension of clouds in air, and the subsidence of ripples and waves in water, but also to the solution of practical problems, such as the flow of water in rivers and channels, and the skin resistance of ships.

The treatment of burns may include the removal of dead tissue ( debridement ), applying dressings to the wound, fluid resuscitation, administering antibiotics, and skin grafting.

A blister is a small pocket of fluid within the upper layers of the skin, typically caused by forceful rubbing ( friction ), burning, freezing, chemical exposure or infection.

Patients may feel pain on the skin around the ulcer, and fluid may ooze from the ulcer.

This involves the insertion of a needle through the skin and into the pericardium and aspirating fluid under ultrasound guidance preferably.

They found a lump of skin and horse flesh ; when Mrs. Lewis touched it, the flesh oozed a greenish fluid which burned her hand.

These mechanisms are based on the external ( skin ) or internal contact involved in machining work, including touching the parts and tooling ; being splattered or splashed by the fluid ; or having mist settle on the skin or enter the mouth and nose in the normal course of breathing.
