With Revised Answers
Which of the following helps to prevent pathogens from invading the body?
a) histamines
b)mucus
c)t-cells
d)macrophages - answer✔✔mucus, skin, secretion (first step).
A bacteria cell enters the body through a cut in the skin. Which of the following describes the
immune response that would occur next?
a) cytotoxic t-cells
b)helper t-cells are activated
c)histamines are released
d) antigens are released - answer✔✔histamines (inflammatory response) are released
Which of the following types of cells produce antibodies?
a) T-cell
b)plasma-cells
c)memory cells
d)macrophages - answer✔✔plasma-cells (The helper T cell induces
the B cell to multiply rapidly into secretory cells called "plasma cells." These plasma cells will
then produce large amounts of an antibody that can bind the antigen.)
which of the following best describes the purpose of a vaccine?
A.)To produce extra inflammatory responses such as the release of histamines
B.)To practice passive immunity

C.)To produce antibodies in case of future infection
D.)To increase macrophage production - answer✔✔to produce antibodies in case of future
infection. (Vaccinations introduce antigens, which are weakened or killed, to elicit an immune
response.)
Which of the following parts of the male genitourinary system also transports sperm?
A. Ureter
B. Urethra
C. Uterus
D. Urinary bladder - answer✔✔urethra (In males, the urethra passes through the penis and also
carries sperm. Females have a much shorter urethra)
Which of the following waste products from digestion does the kidney remove?
A. Nitrogen
B. Sodium chloride
C. Protein
D. Carbon - answer✔✔nitrogen nitrogenous waste from protein digestion is toxic and must be
removed because it will form ammonia.
Which of the following best describes the outcome if the kidneys stopped functioning?
A. Blood would increase its carbon dioxide concentration.
B. Blood would fill with waste and the human body would not be able to maintain homeostasis.
C. The kidneys would fill with urine.
D. The frequency in which a human excretes urine would increase. - answer✔✔blood would fill
with waste and the human body would not be able to maintain homeostasis.
Which of the following structures is the functional unit of the kidney?
A. Renal capillaries
B. Glomerulus
C. Nephron
D. Cortex - answer✔✔nephron (The functional unit of the kidney is the nephron.)

In two to three sentences, explain the purpose of blood pressure in the kidney. - answer✔✔The
pressure of the blood helps the glomerulus
filter out wastes and return vital nutrients through the renal vein to the blood. Nephrons are a
system of microscopic tubes that use
various pressure levels to remove wastes and reabsorb important molecules and water.
Which of the following lists the primary parts of the heart?
A. Blood cells
B. Muscle tissue split into two chambers
C. Muscle tissue split into four chambers
D. Four ventricles - answer✔✔muscle tissue split into four chambers
Which of the following blood components is responsible for transporting oxygen?
A. Red blood cells
B. Plasma
C. Dissolved gases
D. Leukocytes - answer✔✔Red blood cells ( RBC contain hemoglobin and transport oxygen
from the lungs to the rest of the body.)
Which of the following chambers pumps blood toward the lungs?
A. Left atrium
B. Right atrium
C. Left ventricle
D. Right ventricle - answer✔✔RV. (The right ventricle pumps the blood toward the lungs, where
it picks up oxygen and loses carbon dioxide.)
Which of the following statements best describes the function of veins?
A. Veins carry deoxygenated blood.
B. Veins carry oxygenated blood.
C. Veins carry blood back to the heart.
D. Veins carry blood away from the heart. - answer✔✔(C) Then, the oxygenated blood
returns to the heart through veins.
