Which of the following is the function of the lacrimal gland?

A. Peristalsis, the wave-like contraction of the digestive tract, is typically decreased during sympathetic stimulation. The sympathetic nervous system tends to slow digestive processes as the body prioritizes "fight-or-flight" responses.

B. Bladder tone is typically decreased by sympathetic stimulation. The sympathetic nervous system causes relaxation of the bladder, inhibiting urination during stressful situations.

C. Heart rate increases with sympathetic stimulation. The sympathetic nervous system prepares the body for action by increasing heart rate, enhancing blood flow to muscles, and increasing energy levels.

D. Saliva production decreases with sympathetic stimulation. The body reduces non-essential functions such as salivation during stress, focusing energy on immediate survival functions.

A. Type AB positive blood is the universal recipient because individuals with this blood type can receive blood from all other blood types (A, B, AB, and O) due to the presence of both A and B antigens on their red blood cells, and the Rh factor being positive allows them to accept Rh-positive or Rh-negative blood.

B. Type O negative blood is the universal donor, not the recipient. It can be given to any patient, but those with O negative blood can only receive from other O negative donors.

C. Type B negative can only receive blood from B negative or O negative blood types, limiting its compatibility with other blood types.

D. Type A positive individuals can receive blood from type A, type O, type B, and AB, but not as universally as AB positive, which is the universal recipient.
