- 1Bloodtransports oxygen and nutrients to body cells & carry away carbon dioxide and metabolic wastes
- 2Plasmacontains 10% proteins, ions, nutrients, waste, and hormones
- 3What is the blood volume of an adult male & female?male- 5-6L
female- 4-5L - 4Whole blood is __% plasma and __% elements: which are (3 types)55% plasma and 45% formed elements:
erythrocytes, leukoctyes, and platelets - 5Where are all formed elements in the blood formed at?by stem cells in red bone marrow
- 6Erythrocytesred blood cells;
transport oxygen - 7Leukocyteswhite blood cells;
active in phagocytosis (eating bacteria) (neutrophils & monocytes) and antibody formation (lymphocytes) - 8—
- 93 GranulocytesNeutrophils: 1st MOST leukocyte
Eosinophils: 4th most leukoctye
Basophils: 5th LEAST leukoctye - 102 AgranulocytesLymphoctes: 2nd most leukocyte
Monoctyes: 3rd most leukocyte - 11Plateletsactive in the process of blood clotting
- 12Describe the flow of blood through the heart.Arrives via vena cava >>into R atrium>> tricuspid valve >>into R ventricle >>pulmonary semilunar valve >>to pulmonary artery >>lungs >>to pulmonary veins >>into L atrium >>mitral valve >>into L ventricle >>aortic semilunar valve >>leaves via aorta
- 13Blood is supplied to the heart myocardium (heart muscle) through the ______ and drains through the _______.coronary arteries
coronary sinus - 14Deflections of the ECG represent _________the electrical activity that precedes contraction and relaxation
- 15Systole(pumping)
contraction phase of the cycle
blood leaves the heart - 16Diastole(filling)
relaxation phase
blood comes into the heart - 17Arteries carry blood ____ the heartaway from
- 18Veins carry blood ____ the heart.to
- 19Arteries carry blood in ____ pressure. Veins carry blood in ____ pressure.high
low - 20Capillariessmallest of vessels;
exchange of water, nutrients, waste products between blood & tissue - 21Arteriolessmallest arteries that are away from the heart
- 22Difference between negative & positive feedback?Neg-used to maintain homeostasis; activates with the lack of something
Pos-increase output; activates at the presence/signal of something - 23Antigensmarkers on your RBC
A - A antigens
B - B antigens
AB - A and B antigens
O - no antigens - 24Antibodiesproteins that are "against" specific antigens
A - anti-B
B - anti-A
AB - no antibodies
O - both anti-A & anti-B - 25What kind of blood can a person get if they have: A , B , AB , O bloodtype?A - A or O
B - B or O
AB - A, B, or O
O - O - 26Rh blood groupRh+ = Rh antigens
Rh- = no Rh antigens
Anti-Rh antibodies are formed in Rh- individuals when in contact with Rh+ blood. Nothing bad the first time, but will agglutinate the next time. - 27Which blood type is a universal donor?O-
- 28Function of the respiratory systemsupplies oxygen to the body & eliminates carbon dioxide
- 29Respiratory system organsnose, pharynx, larynx, trachea, bronchi, lungs w/ thier alveoli, diaphragm, muscles surrounding the ribs
- 30External respirationexchange of gases between the atmosphere and the blood through the alveoli
- 31Internal respirationexchange of gases between the blood and the body cells
- 32Inhalation requires the contraction of the ______ to enlarge the thoracic favity and draw air into the lungs.diaphragm
- 33Right lungis bigger & heavier
has 3 lobes - 34Left lungsmaller because the heart is more to the left
has 2 lobes - 35SA node AV nodeSA- primary pacemaker of the heart, faster
AV-a gate to control ventricles
