Which of the following types of immunity is acquired through a varicella vaccination?

a: Receptor - Receptors are proteins that bind to signaling molecules (ligands) outside the cell and initiate cellular responses but do not typically facilitate ion movement.

b. Channel-Integral membrane proteins called ion channels create pores in the cell membrane, allowing specific ions to pass through, thus facilitating ion movement into or out of the cell.

c: Ligand - Ligands are signaling molecules that bind to receptors, activating them, but they do not facilitate ion movement.

d: Peripheral - Peripheral proteins are found on the surface of the cell membrane but are not typically involved in creating ion channels

a. Subclavian vein: The lymphatic system drains lymph into the cardiovascular system at the subclavian veins, specifically where the lymphatic ducts (thoracic duct and right lymphatic duct) empty.

b. Carotid artery: This is an artery supplying blood to the brain, not involved in returning lymph.

c. Ascending aorta: This is the part of the aorta that rises from the heart and distributes oxygenated blood, not involved in lymph return.

d. Jugular vein: While close to the lymphatic ducts, lymph specifically drains into the subclavian veins.
