Answer: B
Explanation:
The T helper cell needs to acttivate the T cyctotoxic cell in order for the Tc cell to go do its work.
Once the TC cell is active it interacts with MHC-1 proteins on the surface of the infected host cell, this allows the Tc cell to recignise the host cell and begin secreting cytotoxins (perforins and granzymes) in order to degrade the infected cell and cause apoptosis (controlled cell death)
Answer:
total blood volume
Explanation:
Resistance to blood flow or vascular resistance refers to the slow down of the blood flow due to friction between the flowing blood and the walls of the blood vessels.
The resistance to blood flow is regulated by the viscosity of blood, total length, and diameter of the blood vessels. Higher blood viscosity imparts more resistance to the blood flow. The reduced diameter of blood vessels also restricts the blood flow through the blood vessels. Similarly, the resistance to the blood flow is directly proportional to the total length of the blood vessels.
However, total blood volume present in the body of the organisms does not affect vascular resistance. The total blood volume affects the blood pressure which in turn would affect the systemic vascular resistance.
