VOCABULARY
What is erythrocytes.
What is hemopoiesis.
Granulocyte that fights infections by phagocytosis.
What is neutrophils.
A father with type AB blood has a child with a mother whose blood type is A-. The child has a blood type of B-. What Rh factor alleles does the father have? What blood type alleles and Rh factor alleles does the mother have?
What is the father has AB alleles and Rh+ and Rh- alleles. The mother has AO and two Rh- alleles.
If the father is AB, then he has a A allele and a B allele. If the mother is type A, she is either AA or AO. Since the child is B, the child must have gotten the B allele from the father. The only way to be type B, then, is to get an O from the mother. The mother, then, is AO. Since Rh-negative is recessive, the child must have two Rh-negative alleles. So, the child must have inherited one from each parent. The only way the father can have a Rh-negative allele and be Rh positive is to be heterozygous.
During ventricular systole are the atria contracted or relaxed?
What is relaxed.
Blood that travels through the aorta is?
What is oxygenated.
In the lungs, the blood becomes ______________.
What is oxygenated.
White blood cells that perform various defensive functions in the blood.
What is leukocytes.
The phase in the cardiac cycle in which the ventricles contract.
What is systolic phase.
Agranulocyte that fights infections by phagocytosis.
What is monocyte.
A region in a blood vessel has prothrombinase in it. Which stage of hemostasis (not what stage of coagulation) is taking place?
What is the blood coagulation phase (third phase). Since prothrombinase is present, that means that blood coagulation is occurring.
During ventricular systole are the ventricles contracted or relaxed?
What is contracted.
The blood travels to the tissues of the body and returns to the heart. When is reaches the heart, it is ________________.
What is deoxygenated.
The blood comes back from the lungs and returns to the ___________________.
What is left atrium.
Cell fragments in blood that prevent blood loss.
What is platelets.
The phase of the cardiac cycle in which the ventricles relax.
What is diastolic phase.
Cells that carries oxygen in the blood.
What is erythrocyte.
Of the following chemicals, which exist only when the blood coagulation process is occurring? Factor IX, activated factor XII, fibrinogen, calcium ions, thrombin, fibrin
What is activated factor XII, thrombin, and fibrin. Blood coagulation factors are always in the blood. However, the activated factors are only in the blood during coagulation. Calcium ions are always in the blood-they help the coagulation process once it begins. Thrombin and fibrin are made as a result of the coagulation process, but fibrinogen is always there.
Is the atrioventricular valves open or closed during ventricular systole.
What is closed.
Deoxygenated blood is returned to the ____________.
What is right atrium.
From the right atrium, the blood travels through the ______________ and _______________ to get to the ______________.
What is left atrioventricular canal, left atrioventricular valve (bicuspid or mitral valve), and left ventricle.
The fluid portion of the blood, which is mostly water.
What is plasma.
The smallest arteries that sill have three tunics.
What is arterioles.
Cell that produces antibodies.
Cell that fights inflammation.
What is lymphocytes and what is eosinophils.
In what type of blood will you find no antibodies against A or B or Rh antigens?
What is AB+. Type AB blood has both A and B antigens, so it cannot form antibodies against these antigens. If the blood is also Rh-positive, then it has the Rh antigen and cannot make antibodies against it.
Is the semilunar valves open or closed during ventricular systole?
What is open.
What is the right atrioventricular canal, the right atrioventricular valve (tricuspid valve), and the right ventricle.
Finally, the blood passes through the _____________ to get back into the aorta.
What is the aortic semilunar valve.
Tiny, thin-walled blood vessels that allow the exchange of gases and nutrients between the blood and cells.
What is capillaries.
Small veins that do not have three tunics but instead have only an endothelium, a basement membrane, and a few smooth muscle cells.
What is venules.
Cell that releases histamine and heparin.
What is A-. If the blood has antibodies against the B antigen, it cannot be B or AB blood. O has antibodies against the B antigen, but is also has antibodies against the A antigen. So, the type is A. If is has antibodies against the Rh antigen, then it cannot be Rh+. Rh- people do not form anti-Rh antibodies unless exposed to the Rh antigen.
The __________ carries blood from the heart to the rest of the body.
What is the aorta.
What is the pulmonary semilunar valve.
The deoxygenated blood returns to the right atrium via the __________________, __________________, and _______________.
What is the superior vena cava, the inferior vena cava, and the coronary sinus.
