Circulatory Test
What makes up the composition of blood?
-red blood cells -white blood cells -platelets -plasma
ventricle
A lower and the most muscular chamber of the heart
How does agglutination occur?
Aglunation is when antigens bind with antibody and they create a blood clot.
agglutination
Antigens binds with the antibodies and the blood clots
What determines different blood types
Antigens on rbc
Why can't a person with A blood receive AB blood
B antibodies in blood would attach to the B antigens on rbc and form blood clot
Where does the pulmonary circulatory system allow the exchange of oxygen and carbon dioxide to take place?
Between the lungs and all the blood stream
Where are blood cells made?
Bone marrow
The pulmonary vein is the only vein that. . .
Carries a high volume of oxygen
arteries
Carry blood away from heart away from heart
platelets
Cell fragments of large cells made in bone marrow, no nucleus, essential to form blood clots
capillaries
Connects arteries to veins, walls are one cell thick, allows for Rapid exchange of gases and nutrients, Thin blood vessels that send oxygen and nutrients to the cells and tissues
What is at the bottom of the test tube?
Dense rbc
What determines the different blood types?
Determined by the type of antigen on the rbc
The pulmonary artery is the only artery that . . .
Does not carry a high volume of oxygen
What is the function of the valves in the heart?
Keep blood flow in one direction, not backwards
Type AB blood?
No antibodies, and A and B antigens
Coronary system considered a separate circulatory system?
None of the answers
why is blood red
Oxygen binds to the hemoglobin on rbc
What is at the top of the test tube?
Plasma, carbon dioxide, nutrients, waste, etc
blood pressure
The force blood exerts against walls of a blood vessel
atrium
Two upper cavities in the heart that send blood to the ventricles
What is in the middle of the test tube
Wbc, to fight infection
Where does the systemic circulatory system supply blood
all the organs above
coronary system
circulation of blood in the blood vessels of the heart muscle (myocardium).
Why are the walls of capillaries only one cell thick?
diffusion of nutrients and gases
Why is blood red?
it turns red when the protein absorbs oxygen
anemia
lacks enough healthy red blood cells or hemoglobin.
hemoglobin
oxygen carrying pigment in red blood cells, contains iron, iron binding agent
systemic system
part of the cardiovascular system which carries oxygenated blood away from the heart to the body, and returns deoxygenated blood back to the heart.
pulmonary system
portion of the circulatory system which carries deoxygenated blood away from the right ventricle of the heart, to the lungs, and returns oxygenated blood to the left atrium and ventricle of the heart (blood and lungs), organs that help breathing
veins
returns deoxygenated blood to heart, blood from the lower body returns in the inferior vena cava, blood from the upper body returns in the superior vena cava
Pulse
rhythmic beating in the arteries caused by the beating of the heart, regulates blood flow through the artery
When doc takes your blood pressure. . .
the 1# is when the ventricles contract and the 2# is when the ventricles relax
blood antibodies
these are antibodies (fight infection) that are paired with the antigens attached to red blood cells, so if there is a certain antigen on the red blood cell then the opposite type of antibodies will be created to fight off any blood types that doesn't t have the same antigens. A blood has B antibodies
What are the functions of blood?
transport, protection and regulation -carry oxygen to all parts of body -help fight infection -transports nutrients, hormones, waste -Fight disease
