cardiovascular study guide 1 Flashcards
The mineral necessary for the production of RBCs
Copper
Liquid part of blood containing water @ other substances (watery straw-colored)
Plasma
A clot within a blood vessel obstructing the flow of blood throughout eh circulatory system
Thrombus
Responsible for the formation of blood clots
Fibrinogen
Protein found in red blood cells responsible for carrying oxygen from the lungs to all other tissues of the body
Hemoglobin
Protein used to check for anemia
Hemoglobin
The stopping of blood flow
Hemostasis
Hemostasis can be divided into 3 Stages
- Vascular spasms
- Platelet plug formation
- Coagulation
High or elevated blood pressure
Hypertension
Abnormally low blood pressure
Hypotension
Facts about Leukocytes
- White blood cells
- A colorless blood corpuscle capable of ameboid movement
- Cheif function is to protect body against microorganisms causing disease
Period of relaxation of the heart
Diastole
Period of contraction of the heart
Systole
Heart muscles contract and pumps blood from chambers into the arteries
Widening of blood vessels that results from relaxation of the muscular walls of the vessels. (the diameter of the interior of the vessel widens)
Vasodilation
A person of blood group O who can donate blood to recipients of any ABO blood group
Universal Donor
A person with AB+ can receive blood from anyone
Universal Recipient
Outermost layer of a blood vessel
Tunica Adventitia (also known as Tunica Externa)
A compound in the liver and other tissues that prevents blood clots
Heparin
Largest Artery
Aorta
Longest Vein of Body
The Great Saphenous Vein
Begins on medial side of foot, rises up along inner side of leg @ penetrates deep into the thigh
When phagocytes engulf @ destroy the microorganisms of disease. It is enhanced by products of the immune system called antibodies.
Phagocytosis
A small nonnucleated disklike cytoplasmic body found in blood plasma that is derived from a megakaryocyte and promotes blood clotting.
Platelets
also called blood platelet or thrombocyte
A sudden constriction of the blood vessel causing reduction or stoppage in blood flow
Vascular Spasm
Specialized muscle fibers found in heart. Located in the endocardium.
Function-To relay impulses from the bundle to ventricles, causing a contraction.
Purkinje Fibers
(When electrical impulses are sent along purkinje fibers it causes ventricles to contract. The contraction produces enough force to eject blood from heart necessary for circulation)
