Cardiovascular 1 Flashcards
What is the purpose of valves in the veins
To prevent backflow of blood
Continuous capillaries
Are the most abundant type of capillary in the body
Which of the following statements describes the endocardium
It is continuous with epithelial lining of the large blood vessels
Bilirubin
Is excreted by the liver
Is a breakdown product from the heme pigment
Individuals with the blood type AB are referred to as the universal recipient because they..
Do not produce any antibodies within the ABO blood group
The primary Function of red blood cells is
Transport oxygen to the cells of the body
An individual with RH- blood will have anti-D antibodies
False
Small muscular vessels regulating blood flow into capillary beds
Arterioles
Vessels composed of tunica intima only
Capillaries
Small vessels draining capillary beds
Venules
Thick walled vessels carrying blood AWAY from the heart
Arteries
Permeable vessels which permit diffusion
Capillaries
Thin walled vessels transporting blood TO the heart
Veins
Vessels containing valves to prevent back flow
Veins
Which of the following is a type of capillary that has pores in the endothelium, thus allowing filtration of blood to occur?
Fenestrated capillaries
Blood in the pulmonary veins flow into the
Left atrium
How many oxygen molecules O2 can one hemoglobin bind
4
The systemic circulation
Includes the coronary circulation
Haematopoiesis
Production of blood cells
An individual with blood type O will exhibit __ antigens and produce ___
Antibodies.
No
Anti-A & Anti B
An individual with type ___ blood will exhibit ____ antigens and produce anti-A antibodies
B
B
Haematopoiesis occurs within
Bone marrow
An individual with A+ blood will have or produces
A-Antigen in their red blood cells
Continuous capillaries
Are the most abundant type of capillary in the body
Tissue layers surrounding the heart wall superficial to deep
Fibrous pericardium
Parietal serous pericardium
Visceral serous pericardium
Myocardium
Endocardium
Which of the following is a function of the pericardium
Prevents overfilling of the heart
All individual with RH- blood will have anti-D antibodies
False
Which chamber of the heart has the thickest myocardium
Left ventricle
Adjacent cardiac muscle cells are connected by
Intercalated discs
The chamber of the heart that receives blood from the systemic circulation
Right atrium
Chamber that pumps blood to the lungs
Right ventricle
Chamber that receives poorly oxygenated blood from the body
Right atrium
Chamber that receives oxygenated blood from the lungs
Left atrium
Valve between the left atrium and left ventricle
Bicuspid valve
Valve between the right ventricle and pulmonary trunk

Chamber that pumps blood into the aorta
Left ventricle
Valve between the left ventricle and aorta
Aortic semilunar valve
Valve between the right atrium and right ventricle
Tricuspid valve
Blood type that produces anti-antibodies
