Question
Chapter 19, Problem 1CYR
Summary Introduction
Introduction:
Blood is a fluid connective tissue that circulates in the body to meet its nutritive and physiological needs. It comprises plasma and formed elements. Formed elements comprise various cellular and cellular fragments that are generated by the process of hematopoiesis, whereas the plasma mainly comprises water and plasma proteins.
Expert Solution & Answer
Answer to Problem 1CYR
Correct answer:
The mast cell is not a formed element of the blood.
Explanation of Solution
Explanation for the correct answer:
Option (c) states that mast cell is not a formed element of the blood. A mast cell is a type of basophil (white blood cell) that differentiatesbetween tissues to perform its functions. Mast cells are the immune regulators of the body that secrete chemical substances to fight various infections and participate in allergic reactions. Hence, option (c) is correct.
Explanation for the incorrect answers:
Option (a) states that erythrocyte is not a formed element. Erythrocytes are suspended in the plasma of the blood. These are the red blood cells and area type of a formed element of the blood. So, it is an incorrect option.
Option (b) states that leukocyte is not a formed element. Leukocytes are white blood cells suspended in blood plasma and are a formed element of the blood. So, it is an incorrect option.
Option (d) states that platelet is not a formed element. Platelets are cell fragments found in blood and are a formed element of the blood. So, it is an incorrect option.
Hence, options (a), (b), and (d) are incorrect.
Conclusion
Therefore, it can be concluded that mast cells are not formed elements of the blood. They help in fighting against the infection.

The diagram below illustrates a quorum sensing pathway from Staphylococcus aureus. Please answer the following questions.
1. Autoinduction is part of the quorum sensing system. Which promoter (P2 or P3) is critical for autoinduction?
2)This staphylococcus aureus grows on human wounds, causing severe infections. You would like to start a clinical trial to treat these wound infections. Please describe:
a) What molecule do you recommend for the trial. Why?
b) Your trial requires that Staphylococcus aureus be isolated from the wound and submitted to genome sequencing before admittance. Why? What are you testing for?
3) If a mutation arises where the Promoter P3 is constitutively active, how would that influence sensitivity to AIP? Please explain your rationale.
4) This pathway is sensitive to bacterial cell density. Describe two separate mutation that would render the pathway active independent of cell density. Briefly explain your rationale.
