What is an example of mechanical digestion?
Mastication
Absorption
Catabolism
Anabolism
The Correct Answer is A
A. Mastication: Mechanical digestion involves physically breaking down food into smaller pieces, and mastication is a prime example of this.
B. Absorption: This is the process by which nutrients pass from the digestive system into the bloodstream, not a form of mechanical digestion.
C. Catabolism: Catabolism refers to chemical processes that break down molecules within the body, not mechanical digestion.
D. Anabolism: This refers to the synthesis of complex molecules from simpler ones, not related to the physical breakdown of food.

Correct Answer is A
Explanation
A. Enters the superior or inferior vena cava; exits the pulmonary arteries: Deoxygenated blood from the body enters the heart through the superior or inferior vena cava and flows into the right atrium. It then passes into the right ventricle and exits through the pulmonary arteries to the lungs for oxygenation.
B. Enters the aorta; exits the pulmonary veins: The aorta and pulmonary veins both handle oxygenated blood, not deoxygenated blood, making this incorrect.
C. Enters the superior or inferior vena cava; exits the coronary arteries: The coronary arteries supply the heart muscle itself with oxygenated blood, so this is incorrect for deoxygenated blood.
D. Enters the pulmonary veins; exits the aorta: Both the pulmonary veins and the aorta are part of the oxygenated blood circuit, making this incorrect for deoxygenated blood flow.
Correct Answer is B
Explanation
A. The testes would not maintain the proper temperature: Temperature regulation of the testes is controlled by the scrotum and muscles, not the prostate.
B. The flow of urine may be blocked or slowed: Benign prostatic hyperplasia (BPH), or an enlarged prostate, can compress the urethra, leading to difficulty urinating or weak urine flow.
C. Seminal fluid would not have the proper pH: The prostate contributes fluids to semen, but BPH typically affects urine flow more than seminal fluid pH.
D. Sperm would not be allowed to fully mature: Sperm maturation occurs in the epididymis, not in the prostate.
