<span>When a person smokes a cigarette, the body responds immediately to the chemical nicotine in the smoke. Nicotine causes a short-term increase in blood pressure, heart rate, and the flow of blood from the heart. It also causes the arteries to narrow. Carbon monoxide reduces the amount of oxygen the blood can carry. This, combined with the effects produced by nicotine, creates an imbalance in the demand for oxygen by the cells and the amount of oxygen the blood is able to supply.
So the answer is D. increased heart rate</span>
Systemic lupus erythematosus (SLE) is a rheumatic disease attributed to autoimmune mechanisms.
Systemic lupus erythematosus (SLE, lupus) is characterized by a global loss of self-tolerance with activation of autoreactive T and B cells, leading to the production of pathogen autoantibodies and tissue damage.
Innate immune mechanisms are required for aberrant adaptive immune responses in SLE. Recent advances in basic and clinical biology have shed new light on the disease mechanisms of lupus. This review article describes recent studies that provide valuable insights into disease-specific therapeutic targets.
Systemic lupus erythematosus (SLE or lupus) is a systemic autoimmune disease with inflammation of multiple organs. SLE is characterized by the production of pathogenic autoantibodies against nucleic acids and their binding proteins, reflecting a global loss of self-tolerance.
Loss of tolerance with subsequent immune dysregulation is the result of genetic factors in the context of environmental triggers and stochastic events, with recent studies implicating more than 30 genetic loci in disease pathogenesis.

Answer:
The best answer to the question: What disease would you be concerned about? Would be: Rabies.
Explanation:
Rabies is a viral disease that is caused by the lyssaviruses, or better known a the rabies virus. It is an almost-always fatal disease that attacks the CNS not just in animals, but in humans as well. The disease can be contracted not just from an animal bite, but also by the contact with infected saliva from a carrier animal. In this case, the dog´s saliva and foam has become a carrier of the virus and if you touch that saliva, the virus will infect you if you either have an open wound on your skin, a simple scratch, or if you bring your hands to your mouth, or eyes. From then on, the virus will infect and spread to your CNS through your peripheral nerves and between one and three months, all the signs and symptoms will fully develop. In humans rabies is almost always deadly.
