Flashcards in Bleeding Chpt. 23 Deck (23):
1

The main artery that receives blood from the left ventricle and delivers it to all the other arteries that carry blood to the tissues of the body.

Aorta

2

The smallest branches of arteries leading to the vast network of capillaries

Arterioles

3

A blood vessel, consisting of three layers of tissue and smooth muscles that carries blood away from the heart

Artery

4

The small blood vessels that connect arterioles and venules; various substances pass through capillary walls, into and out of the interstitial fluid and then on to the cells

Capillaries

5

The formation of clots to plug opening in injured blood vessels and stop blood flow

Coagulation

6

A bruise, or ecchymosis

Contusion

7

Discoloration of the skin associated with a closed wound; bruising

Ecchymosis

8

A nosebleed

Epistaxis

9

Vomited blood

Hematemesis

He•ma•tem•e•ses

10

A mass of blood in the soft tissues beneath the skin

Hematoma

11

A congenital condition in which the patient lacks one or more of the blood's normal clotting factors

Hemophilia

12

Coughing up blood

Hemoptysis

He•mop•ty•ses

13

Bleeding

Hemorrhage

14

A condition that occurs when the level of tissue per fusion decreases below that needed to maintain normal cellular function, also called shock

hypoperfusion

15

A condition in which low blood volume, due to massive internal or external bleeding or extensive loss of body water, result in inadequate perfusion

Hypovolemic shock

16

Black, foul-smelling, tarry stool containing digest blood

Melena

17

Circulation of blood within an organ or tissue in adequate amounts to meet the current needs of the cellls

Perfusion

18

A point where a blood vessel lies near a bone

Pressure point

19

A condition in which the circulatory system fails to provide sufficient circulation so that every body part can perform its function; also called hypoperfusion

Shock

20

The bleeding control method used when a wound continues to bleed despite the use of direct pressure and elevation; useful if a patient is bleeding severely from a partial or complete amputation

Tourniquet

21

Narrowing of a blood vessel, such as with hypoperfusion or cold extremeties

Vasoconstiction

22

The blood vessels that carry blood from the tissues to the heart

Veins

23

Very small, thin-walled vessels

Venules
