chapters 13,14,15

A band cell is immature white blood cell
WBC's recognize foreign antigens & produce antibodies lymphocytes
organ that produces erythropoietin during hypoxia kidney
oxygen carrying protein of the RBC's hemoglobin
blood clot is made of fibrin
Backflow from the ventricles to the atria is prevented by the: mitral and tricuspid vlaves
each normal heart beat is initiated by SA node
vessel in which the left ventricle pumps blood aorta
systole contraction
Normal, healthy adult heart rate 60-100
fetal blood vessel that carries blood from the pulmonary artery to the aorta ductus arteriosus
backflow of blood within a veins is prevented by valves
blood pressure decreases, the kidneys secrete renin
person with type AB blood has which of the following? A and B antigens on the RBC's and neither anti-A nor anti-B antibodies in the plasm
red bone marrow produce? all the types of blood cells
mineral that is needed for chemical clotting calcium
normal pH of the blood 7.35-7.45
in the wall of a large artery that causes it to contract in vascular spasm in an attempt to control bleeding smooth muscle
abnormal clot that forms on a rough surface in an intact vessel thrombus
WBC's that carry out most phagocytosis of pathogens monocytes and neutrophils
function of erythropoietin increase in RBC production
prevent backflow of blood from the arteries to the ventricles? aortic and pulmonary semilunar valves
name for the veins that return blood to the right atrium of the heart superior and inferior vena cava
defines the amount of blood pumped by a ventricle in 1 minute cardiac output
fetal vessel that carries blood from the placenta to the fetus umbilical vein
In capillaries, nutrients are transported from the blood to the tissues through filtration
Numbers in a bp systolic/diastolic
will happen to the blood pressure in cases of large blood loss or hemorrhage it will decrease
ADH will increase blood pressure because it increases water reabsorption by the kidneys
a hematocrit reveal how much oxygen the blood can carry
substance allows RBC's to transport oxygen hemoglobin
move to high altitude would trigger which change in the blood an increased number of reticulocytes
Hemolysis may produce which physical sign jaundice
infecting organism pierces the skin, which of the following WBC's would quickly migrate out of the blood vessels and into tissues to ingest the foreign invaders neutrophils
unwanted part of hemostasis formation of a thrombis
substance, carried by each red blood cell, determines blood type antigen
following will occur if someone with type A blood receives a transfusion with type B blood? agglutination
point of maximum impulse of the heart apex
portion of the heart wall that lines the heart's chambers is endocardium
heart valve controls the flow of blood between the left atrium and the left ventricle mitral valve
name of the great vessel that supplies blood to the right atrium superior and inferior vena cava
myocardium receive its blood supply it receives its blood supply through the right and left coronary arteries
heart's primary pacemaker the sinoatrial node (SA node)
cardiac cycle the series of events that occur form teh beginning of one heartbeat to the beginning of the next
term used to describe the amount of tension, or stretch, in the ventricular muscle just before it contracts preload
vessels that carry blood away form the heart are arteries
reason blood constantly circulates is pressure gradients
Plasma Clear extracellular matrix of blood
Formed Elements Cell and Cell Fragments Make up 45% of blood. include Erythrocytes (RBC) and platelets.
Red Bone Marrow: produce all types of blood cells.
Red Bone Cells Can not divide
Red Blood Cells Delivers oxygen, removes carbon dioxide
hemoglobin over 1/3 of interior RBC is filled with it.
hemoglobin bound to each globin is an iron-containing molecule
hemoglobin 4 ribbon-like protein chains called globin
Blood is what kind of tissue Connective tissue
red blood cells blood and blood forming tissue
Life Cycle of a RBC #1 damaged rbc removed from circulation
Life cycle of a RBC #1 oxygen levels fall
Life cycle of a RBC #2 kidneys detect declining levels of oxygen
Life cycle of a RBC #2 kidneys secrete EPO
EPO Erythtopoletin
Life cycle of a RBC #3 EPO stimulates red Bone Marrow to begin creating new Erythrocytes
Life cycle of a RBC #4 a reticulocyte is released
reticulocyte immature form of an erythrocyte
Life cycle of a RBC #5 after 1-2 days the reticulocyte becomes a mature erythrocyte
Life cycle of a RBC #6 number of RBC increases, oxygen levels rise
Life cycle of a RBC #6 EPO is produced and RBC production declines
breakdown of Red blood Cells #1 liver and spleen ingest/destroy old RBCS
breakdown of Red blood Cells #2 hemoglobin becomes hemo and globin
breakdown of Red blood Cells #3 globin is broken down into Amino Acids
breakdown of Red blood Cells #4 Amino Acids= used for energy=create new proteins
breakdown of Red blood Cells #5 hemo = iron bilirubin
breakdown of Red blood Cells #6 iron is transported to bone marrow to make new hemoglobin
breakdown of Red blood Cells #7 bilirubin becomes bile in intestines
hemolysis excessive destruction of RBCS
jaundice body canot handle excess Bilirubin, so it pools in the tissue turning it a yellow tint ,
polycythemia new RBCS are being made before Old ones can be Destroyed
Anemia insufficient supply of iron in the blood.
White Blood Cells called Leukocytes. crucial to life.
White Blood Cells fewest of formed elements. 5 types of White Blood Cells
White Blood Cells all leukocytes have a nucleus
Platelets (thrombocytes) Second most formed element
Platelets (thrombocytes) play key role in stopping bleeding
Platelets (thrombocytes) live about 1 day
Homopoiesis production of blood
Bile gives feces a brown color
Leukopenia abnormally low wbc
coagulation clotting of blood that involves a complex series of chemical reactions
thrombin transforms plasma protein into fine insoluble fibers
fibrin forms web at the site of an injury
hemophilia deficiency in one of the clotting factors
Universal donor can be give 2 ANY recipient
fibrinolysis dissolution of a blood clot
function of cardiovascular system pump oxygen rich blood throughout the body
where is the heart located? in the Thoracic cavity
Base where vessels enter and leave the heart
apex point of maximum impulse
atrium 2 upper receiving chambers of the heart
ventricles 2 lower pumping chambers of the heart
heart Valves 1 @ end of each ventricle, 1 between each atrium and ventricle
Cuspor leaflets Valves are formed by 2-3 flaps of tissues
Senilunar Valves regulate flow between ventricles and arteries
Artioventricular Valves regulate flow between atrium and ventricles
coronary arteries deliver oxygenated blood to the myocardium
coronary arteries collect deoxygenated blood
coronary arteries (right) supplies blood to rt atrium, rt ventricle, lt inferior part of ventricle & part of lt atrium
coronary arteries (left) supplies blood to left ventricle and most of the interventricular septum
Purkinjle fibers conduct impulses throughout the muscle of both ventricles causing them to contract
SA (sinoatrial node) 60-80 BPM
AV (atrioventricular node) 40-60 BPM
Purkinjle fibers 20-40 PM
Bundle of HIS transmits impulses from the atrioventricular node, to the ventricles of the heart
Electrocardiogram records electrical activity or impulses. DOES NOT record heart contractions.
Arteries Away Arteries carry blood AWAY
Capillaries Connect Capillaries serve to Connect arteries and veins
arterioles resist the flow of blood.
conducting arteries expand as blood surges into them and recoil when ventricles relax
arteries carry blood away from the heart, when the heart pumps it forces blood into the arteries
distributing arteries
veins blood returns to heart in veins. They are very stretchy
large Veins thick thunica externa (vena cava. pulmonary valve)
medium sized veins formed by the convergence on venules on their route towards the heart
medium sized veins contain one-way valves. prevent backflow
venules collect blood from capillaries. can exchange fluid with surrounding tissue.
capillaries link arterioles to venules.
capillaries nutrients, wastes and hormones transferred between blood and tissue
capillaries aren't easily distributed. Vital. also known as exchange vessels.
capillaries fibrous connective tissues = less capillaries
capillaries high metabolic rate tissues- more capillaries
capillaries barely wide enough for blood. thin walls = filtering of substances
pulmonary circulation routes blood from and to the lungs in exchange for 02 and C02
Systemic circulation removes wastes involves arteries and veins, comes from aorta
Heptic Portal Circulation Digestive organs and spleen veins empty into the inferior vena cava
allows liver to modify blood going back to heart and get rid of excess glucose and toxins Heptic Portal Circulation
Diastolic ventricle relaxes
