What does cardiac output measure?
Blood pumped into a ventricle in one minute
Blood pumped into the atria in one minute
Blood pumped by each ventricle in one minute
Blood pumped out of an atrium in one minute
The Correct Answer is C
A. Blood pumped into a ventricle in one minute: This describes venous return but not cardiac output.
B. Blood pumped into the atria in one minute: Cardiac output measures blood leaving the heart, not entering the atria.
C. Blood pumped by each ventricle in one minute: Cardiac output is the amount of blood ejected by each ventricle in one minute. It is calculated by multiplying stroke volume (the amount of blood ejected per beat) by heart rate.
D. Blood pumped out of an atrium in one minute: This describes atrial function but is not related to the definition of cardiac output.

Correct Answer is B
Explanation
A. Pancreas: pancreas secretes enzymes such as amylase (for carbohydrate digestion), lipase (for fat digestion), and proteases (such as trypsin and chymotrypsin for protein digestion). These enzymes are secreted into the small intestine to aid in the digestion of chyme.
B. Stomach: Chyme is a semi-fluid mixture of partially digested food and digestive juices formed in the stomach. The stomach’s muscular contractions mix food with gastric secretions, resulting in this thick paste that is then gradually released into the small intestine for further digestion.
C. Small Intestine: While the small intestine further processes chyme through digestion and absorption, it does not produce it.
D. Large Intestine: The large intestine primarily absorbs water and electrolytes from indigestible food matter and forms waste, but it does not produce chyme.
Correct Answer is D
Explanation
A. Lipids and proteins: While bile is involved in fat digestion, it does not emulsify proteins.
B. Proteins: Bile does not emulsify proteins. Proteins are broken down by enzymes like pepsin.
C. Carbohydrates and proteins: Bile has no role in the digestion of carbohydrates or proteins.
D. Lipids: Bile emulsifies lipids, breaking them into smaller droplets to facilitate enzymatic digestion by lipases.
