What is respiratory distress syndrome? Why do premature infants suffer from RDS? Why do adults suffer from RDS? What are the common treatments for both infants and adults?
Marcus is born with transposition of the great arteries, in which the aorta arises from the right ventricle and the pulmonary artery arises from the left. Assuming no other anatomical abnormalities, trace the flow of blood through his body. What affect will this have on his cardiovascular system? Is correction necessary or could he live a normal life?

Consider the different muscle fiber arrangement bundles (circular, pennate, parallel, and convergent). Briefly define each organization pattern and pick a muscle that would be defined in that category (i.e., circular arrangement orbicularis oris, parallel arragnement rectus abdominis, convergent pectoralis major, and pennate arrangement deltoid.) You must choose a different muscle for each category that was listed as an example to help you get started.
Next, pick one of the muscles you chose in your arrangement category. Identify a movement that would have that particular muscle be an agonist. Next chose an antagonist and a synergist muscle that would be involved in the movement you identified.

Indicate which of the following best illustrates the concept of positive feedback? The concept of negative feedback? Make sure to justify your answer.
An increase in the concentration of H+ in blood causes an increase in H+ excretion in the urine.
An increase in the carbon dioxide concentration of the blood stimulates breathing, which increases the rate at which carbon dioxide is eliminated from the body.
Contractions of the uterus push the fetus against the cervix, which triggers release of oxytocin into the bloodstream. Oxytocin then stimulates stronger contractions of the uterus.

BJ. is a 5-year-old boy who has suffered from repeated upper respiratory infections since he was 16 months old. At 4 years of age, he was diagnosed with allergic asthma. The following winter, at age 5, he was admitted to the hospital twice for acute asthma with a secondary bacterial pulmonary infection.
At the second admission, a complete blood count, sputum culture, and immune status work-up were ordered.
