Topic 1 Flashcards
composed of 4 different components; carries nutrients and oxygen to cells; carries waste and carbon dioxide away from cells
blood
Regulation of internal conditions to maintain conditions necessary for life
homeostasis
the fluid portion of the blood that makes up 55% of the blood’s volume
plasma
blood cell fragments that help in the forming of clots
platelet
AKA erythrocytes; carry oxygen to cells
red blood cells
AKA leukocytes; work in the immune system
white blood cell
AKA white blood cells
Leukocytes
AKA red blood cells
Erythrocytes
a specialized protein that helps to identify and destroy foreign substances in the body
Antibodies
markers on the surface of cells that help to identify the cell to other cells in the body
antigens
antigens
markers
a description of the antigens on the surface of the red blood cells
blood type
has A antigens and make antibodies against B
Type A
Has B antigens and makes antibodies against A
Type B
has both A and B antigens and makes no antibodies
Type AB
has no antigens and makes antibodies against both A and B
Type O
an antigen on the surface of a red blood cell
Rh factor
the organ that powers the movement of blood through the body; has 4 chambers
heart
a section of the heart
chamber
the two lower chambers that push blood out of the heart
ventricle
the two upper chambers that take blood into the heart
atrium
blood that does not have oxygen carried by the hemoglobin of the red blood cells
deoxygenated blood
blood that has oxygen carried by the hemoglobin of the red blood cells
oxygenated blood
the largest vein of the body; carries blood back from the body into the right atrium
vena cava
the largest artery of the body; carries blood out to the body from the left ventricle of the heart
aorta
carries deoxygenated blood from the right ventricle to the lungs
pulmonary artery
carries oxygenated blood back to the left atrium from the lungs
pulmonary vein
carries blood away from the heart
artery
a small artery
arteriole
the smallest blood vessels; where oxygen and nutrients are exchanged for waste and carbon dioxide with cells
capillary
a small vein
venule
carries blood toward the heart
vein
the process of supplying oxygen into cells and removing carbon dioxide from cells; occurs between cells and blood
gas exchange
the movement of materials from high to low concentration
diffusion
the buildup of plaque within arteries; can result in stroke, heart attack
atherosclerosis
high blood pressure
hypertension
interruption of blood flow to a part of the brain
stroke
interruption of blood flow to a part of the heart
heart attack
