Which of the following can be cleared through drainage?

Livor mortis

A clear, watery substance that fills the spaces between cells and tissues throughout the body

Interstitial fluid

Purge presents in this area it is frothy in appearance and will come from mouth and nasal passages

Lungs

Raising both carotid arteries for isolated controlled distribution to the trunk and head

Restricted cervical injection

When conducting cranial aspiration once the small trocar is entered into the nostril it needs to be pushed through the

Ethmoid bone of the cribriform plate

Which of the following organs is located in the right lumbar region?

Greater omentum

Pressure indicated when the embalming machine is running and the rate of flow is closed completely

Potential pressure

Allowing venous drainage to continue the entire time during injection without interuption

Concurrent

During embalming you decided to inject into the femoral artery and drain from the right jugular vein

Split method

When purge presents in the area and it is a coffee ground consistency that may come from the mouth where is it coming from

Stomach

Pressurized injection creates a passive physical transport responsible for diffusion into the tissues

Pressure filtration

During a restricted cervical injection which section of the body would I inject last

The right side of the face

Which of the following valves are located in the begining of the ascending aorta

Semilunar valve

Where is the center for blood drainage in the body located

Right atrium

Injection continues throughout the entire embalming process and drainage is shut off for a selected short period

Intermittent method

Conducting a split injection you are injecting from the right femoral artery where will your desired drainage site be

Right jugular vein

When purge presents in the area it is a creamy white semisolid that may come from the nasal passages

Brain

Pressure that is indicated when the embalming machine is running with the rate of flow open

Actual pressure

Which of the following is a reason for blood drainage

Reduce swelling

What anatomical structure divides the thoracic and abdominal cavities

Diaphragm

Solution passes form machine through tube through arterial tube and into desired artery

Delivery

When too much interstitial fluid is removed during embalming which issue is most likely to occur

Dehydration

Embalming solution will always travel through the path of

Least resistance

Pressure needed to overcome the vascular resistance of the body to distribute the embalming solution to all body areas

Ideal pressure

Solution does not make it to the capillaries and flows through the direct connection between arterioles and venules

Sent directly through to drainage

The amount of embalming solution injected in a given time period. Can also be termed as speed of delivery

Rate of flow

Blood in capillaries along with interstitial fluids can do what to embalming solution

Dilute the embalming solution

The brachiocephalic branch of the aortic arch distributes fluid to

The right side of the face and right arm

If an embalming solution is too diluted the solution will rapidly pass into the tissue fluid and cause

Insufficient preservation and swelling

Involves the movement of a liquid a solvent from a dilute area to a concentrated area

Osmosis

This is a drainage method: arterial solution is never injected while drainage is being taken

Alternate drainage

One of the purposes for drainage is to make room for arterial solution. If room is not made for arterial solution this will result in-

Distention would result without blood drainage

Blood is a

Liquid tissue

All the following are drainage instruments except

Arterial tube

This is a drainage method: injection and drainage occurs at the same time

Continuous drainage

These are multicolored, bottom portion is dark, formed by red blood cells that have graviteated to dependent part of vessel, clear layer on top, jelly-like layer of fibrin

Postmortem clots

Injection of arterial fluid accompanied by blood drainage can do which of the following

Redices postmortem discoloration

Which of the following is an advantage of using a drain tube

Drainage can be stopped to build up intravascular pressure

This is a drainage method: injection continues throughout the embalming and drainage is shut off for a selected short period

Intermittent drainage

The pressure set with the rate-of-flow closed is called what

Potential pressure

During the embalming process new substances will be produced caused by the reaction between the ______ and the ______

Proteins and the preservatives

Postmortem changes can present false signs of arterial solution distribution and diffusion. Which of the following is an example of those postmortem changes

Postmortem staining

When injecting your embalming solutions your pressure needs to overcome what to be able to distribute embalming solution to all areas of the body

Vascular resistance

If an embalming is too diluted the solution will rapidly pass into the tissue fluid and cause

Insufficient preservation and swelling

_______ involves the movement of liquid a solvent from a dilute area to a concentrated area

Osmosis

The _____ are an extension of the inner lining of large vessels

Capillaries

The pressure needed to overcome the vascular resistance of the body to distribute the embalming solution to all body area

Ideal pressure

What happens to the solution that remains in the capillaries flows to the venule

It is pushed out as drainage

Which of the following would be an example of something that would cause extravascular resistance

Visceral weight
