Question

question 7
1 pts
the term blood type refers to the type of blood cell
antibody.
antigen.
transfusion reaction.
question 8
1 pts
the chemoreceptors in the carotid bodies are particularly sensitive to:
hypercapnia.
hypoxia.
a decrease in blood ph.
an increase in the hydrogen ion concentration of the blood.
question 9
1 pts
circulatory shock caused by a drop in the amount of blood in the circulatory system is called_____ shock.
hypovolemic
cardiogenic
anaphylactic
septic

Explanation:

• Question 7: Blood type is determined by the presence or absence of specific antigens on the surface of red blood cells. Antibodies are proteins in the plasma that react with antigens. A transfusion reaction occurs when incompatible blood is transfused.
• Question 8: Carotid body chemoreceptors are highly sensitive to hypoxia (low oxygen levels). Hypercapnia (high carbon dioxide) is more detected by central chemoreceptors. A decrease in blood pH or increase in hydrogen ion concentration (which is related to pH) can also affect chemoreceptors, but the carotid bodies' primary sensitivity in the given options is to hypoxia.
• Question 9: Hypovolemic shock is caused by a significant decrease in blood volume (hypo - volume). Cardiogenic shock is due to heart failure. Anaphylactic shock is an allergic reaction - related vascular collapse. Septic shock is due to severe infection.

Answer:

• Question 7: antigen
• Question 8: hypoxia
• Question 9: hypovolemic
