Human Body Basics Part V Trivia Quiz

Answer: digestive enzyme for protein

Saliva contains secretory amylase, which digests carbohydrates. It also contains lingual lipase, which helps digest fats. The amylase is why bread imparts a sweetness if it is chewed extensively before swallowing. Antibodies are contained in saliva and this is why tooth decay is more prevalent in those individuals who produce little saliva. Saliva also contains many other substances involved lubrication, mineralization, and other functions.

Answer: red blood cells

Bilirubin, a breakdown product of red blood cells which have been destroyed in the spleen or blooodstream, is a major component of bile. After transport to the liver, it is conjugated and incorporated into bile, which emulsifies fats for digestion.

Answer: True

The presence of sugar in the cerebrospinal fluid is a way physicians can determine whether there is a leak of this fluid through other tissues. The amount of glucose it contains is about 2/3 of that contained in the blood.

Answer: fatty acids

Contained in sebum and secreted by the upper dermis and connective tissue in the dermis, fatty acids inhibit fungal growth. Sweat creates more moisture in areas not exposed to open air, leading to increased fungal infection in armpits, groin, and beneath breasts, particularly in obese individuals. Hair follicles have no role in fungal growth or inhibition.

Answer: The percentage of blood ejected from the left ventricle with each heartbeat

The cardiac "ejection fraction" can be measured by an echocardiogram or a gated blood pool scan, frequently known as a MUGA scan. Since all cardiac chambers contain only blood, measuring the volume of the left ventricle when the heart is fully constricted (systole) divided by the volume when the heart is fully dilated or relaxed (diastole)gives the ejection fraction. Any value over 50% is normal.

Answer: There is a blood-brain barrier which separates the pineal gland from the circulation

Unlike the rest of the brain, there is no blood/brain barrier at the pineal gland. It produces melatonin, which is involved with the human sleep/wake cycle.

Answer: heart-heart

The human heart approximates a pear shape, as it is commonly described. The adrenal glands, which are atop the kidneys, are pyramidal, and the prostate is the size and approximate shape of a walnut. Kidney beans are almost a miniature version of the kidney in shape, color, and glistening surface.

Answer: False

No one knows why, but they are not connected. The contraction of the fallopian tubes and the beating of the fimbriae near the point of egg release in the ovary "tease" the egg into the fallopian tubes, unless it doesn't work and you end up with an ectopic pregnancy.

Answer: bile: green bile and red bile

Bile can range from bright yellow to deep forest green, but never red. Yellow marrow is that replaced by fat, and red marrow contains blood forming cells. In functional bone marrow, the percentage that contains blood forming cells is about 100 minus your age. White and red pulp in the spleen contains predominantly white and red cells, respectively.

The gray matter is where your smarts are and the white matter is predominantly fat that insulates your nerve circuits in the brain.

Answer: fat cell

Yes, eating is one of those factors, and exercise is another! Fat cells are also called lipocytes or adipocytes.
