Which of the following is the hormone that regulates urine output?
A. Thyroid Stimulating
B. Antidiuretic
C. Adrenocorticotropic
D. Follicle Stimulating - ANS ✓Antidiuretic
(The antidiuretic hormone is secreted from the posterior pituitary gland to
increase reabsorption of water and sodium from the kidneys. The hormone
helps blood vessels constrict and helps control blood pressure and the
amount of urine produced.)
Which of the following does the respiratory system eliminate when there is
an excess of hydrogen ions in the body?
A. Oxygen
B. Carbon
C. Bicarbonate
D. Lactic Acid - ANS ✓Carbon Dioxide
(Chemoreceptors in the respiratory center of the brain responding to a
rising hydrogen ion concentration (low-PH), causing increased ventilation
and thereby increased elimination of carbon dioxide.)

Blood cells are produced by which of the following?
A. Red bone marrow
B. Lamellae
C. Lacunae
D. Yellow bone marrow - ANS ✓Red bone marrow
(Red blood cells are created through a process called Erythropoiesis.
Through this process 7 days) red blood cells are continuously produced in
the red bone marrow of large bones. In an embryo, the liver is the main site
of red blood cell production)
After passing through the glottis, inspired air then travels through which of
the following structures?
A. Larynx
B. Trachea
C. Pharynx
D. Bronchi - ANS ✓Larynx
Which of the following types of muscle tissue is under voluntary control?
A. Smooth
B. Cardiac
C. Visceral
D. Skeletal - ANS ✓Skeletal

electrolytes is associated with cardiac arrhythmias?

A. Chloride
B. Phosphorus
C. Potassium
D. Sodium - ANS ✓Potassium
(Potassium helps keep your heart beating at the right pace. It does this by
helping control the electrical signals of the myocardium. When potassium
levels are too high, it can lead to an irregular heartbeat.)
Blood pH is measured by the gain and loss of which of the following?
A. Bicarbonate
B. Carbon Dioxide
C. Hydrochloric acid
D. Hydrogen - ANS ✓Hydrogen
(Blood pH is measured by the gain and loss of hydrogen ions. pH refers to
Hydrogen Ion Concentration. Normal pH rage for human body is 7.35 to
7.45)
Which of the following is a structure that filters foreign particles from
lymphatic fluid?
A. Thymus
B. Nodes
C. Tonsils
D. Spleen - ANS ✓Nodes
(The lymph nodes are responsible for filtering foreign particles from
lymphatic fluid)
