6		Which of the following correctly represents the flow of blood through the heart?
			A)	Blood rich in oxygen enters the right atrium. The right atrium contracts, sending blood to the right ventricle. The right ventricle contracts, sending blood to the lungs. Oxygen is exchanged for carbon dioxide. Blood rich in carbon dioxide enters the left atrium. Left atrium contracts, sending blood to the left ventricle. Left ventricle contracts and sends blood out of the aorta to the body.
			B)	Blood rich in oxygen enters the right ventricle. The right ventricle contracts, sending blood to the right atrium. The right atrium contracts, sending blood to lungs. Oxygen is exchanged for carbon dioxide. Blood rich in carbon dioxide enters the left ventricle. The left ventricle contracts, sending blood to the left atrium. The left atrium contracts and sends blood out of the aorta to the body.
			C)	Blood rich in carbon dioxide enters the right atrium. The right atrium contracts, sending blood to the right ventricle. The right ventricle contracts, sending blood to lungs. Carbon dioxide is exchanged for oxygen. Blood rich in oxygen enters the left atrium. The left atrium contracts sending blood to the left ventricle. The left ventricle contracts and sends blood out of the aorta to the body.
			D)	Blood rich in carbon dioxide enters the right atrium. The right atrium contracts, sending blood to lungs. Carbon dioxide is exchanged for oxygen. Blood rich in oxygen enters the left atrium. Left atrium contracts sending blood out of the aorta to the body.
			E)	Blood rich in carbon dioxide enters the right atrium. The right atrium expands, sending blood to the right ventricle. The right ventricle expands, sending blood to lungs. Carbon dioxide is exchanged for oxygen. Blood rich in oxygen enters the left atrium. The left atrium expands, sending blood to the left ventricle. The left ventricle expands and sends blood out of the aorta to the body.
7		Which of the following comments about a kidney transplant is NOT likely to increase the number of live donors?
			A)	Many kidney donors are able to go home after two days.
			B)	The donor can survive with a single kidney.
			C)	The organs from deceased individuals are distributed using a point system that takes into account medical urgency, time on the waiting list, and blood type compatibility. Candidates may be on waiting lists for a year or longer.
			D)	It is necessary for all patients to take immunosuppressive medication for the rest of their lives following transplant.
			E)	The surgical dissection to remove a living donor kidney is done through four small incisions ranging in size from 0.5 to 1.2 cm.
8		Which of the following work within the lungs to absorb oxygen from the air?
			A)	alveoli
			B)	trachea
			C)	bronchial tubes
			D)	diaphragm
			E)	epiglottis
9		How does the male sperm cell differ from the other cells in a man’s body?
			A)	The sperm cell has chromosomes but does not have genes.
			B)	The sperm cell has no chromosomes.
			C)	The sperm cell has twice as many chromosomes as every other cell.
			D)	The sperm cell has half as many chromosomes as every other cell.
			E)	The sperm cell has 23 more chromosomes than all other cells.
10		The genetic makeup (or genome) of the mouse, one of the most frequently used mammals in medical and behavioral research, will be the subject of a major new research program. The first tasks include mapping—determining the physical organization of the mouse’s 21 chromosomes—and sequencing or identifying the order of the estimated three billion chemical bases, or letters, of the DNA in the mouse genome. Mice and humans share many of the same fundamental biological and behavioral processes. This makes the mouse a valuable laboratory model for human disease. If researchers know the genetic makeup of the mouse and compare it to the DNA of humans, they will be able to assess predisposition to disease, predict responses to environmental agents and drugs, and design new medicines. Why do researchers find it valuable to study the genetic makeup of mice?
			A)	Mice have only 21 chromosomes.
			B)	Mice are frequently used as laboratory animals.
			C)	Mapping a mouse’s chromosomes will be harder than mapping a human’s chromosomes.
			D)	A map of mouse genes can be used instead of human genes.
			E)	Mice and humans are alike in many biological and behavioral ways.
