Both pancreatic juice and bile are secreted into the duodenum.
A. false
B. true
This question is an excerpt from Nurse Dive's nursing test bank - Anatomy and physiology proctored exam ( hellen fluid college). Take the full exam now
Full Explanation
Pancreatic juice and bile are indeed secreted into the duodenum. Pancreatic juice, which contains digestive enzymes, is released from the pancreas, while bile, which emulsifies fats, is secreted from the liver and stored in the gallbladder before being released into the duodenum.
Similar Questions
____________ happens in the cytoplasm, whereas _____________ happens in the mitochondrion.
A. Aerobic respiration; anaerobic fermentation
Aerobic respiration; anaerobic fermentation: Aerobic respiration primarily occurs in the mitochondrion, and anaerobic fermentation occurs in the cytoplasm. Therefore, this is incorrect.
B. Glycolysis; the citric acid (Krebs) cycle
Glycolysis; the citric acid (Krebs) cycle: Glycolysis occurs in the cytoplasm, breaking down glucose into pyruvate. The citric acid (Krebs) cycle takes place in the mitochondrion, where it further processes pyruvate for energy production.
C. The citric acid (Krebs) cycle; mitochondrial electron-transport
The citric acid (Krebs) cycle; mitochondrial electron-transport: Both the citric acid cycle and the mitochondrial electron transport chain occur in the mitochondrion.
D. Anaerobic fermentation; glycolysis
Anaerobic fermentation; glycolysis: Glycolysis occurs in the cytoplasm and is the first step in both aerobic and anaerobic pathways, but anaerobic fermentation also occurs in the cytoplasm, so this option is not accurate in distinguishing between processes happening in different locations.

During digestion, what is the major site of nutrient absorption?
A. Small intestine
Small intestine is the primary site of nutrient absorption. The majority of digestion and absorption of nutrients such as carbohydrates, proteins, and fats occurs in the small intestine, particularly in the duodenum and jejunum.
B. Pancreas
Pancreas secretes digestive enzymes into the small intestine but does not absorb nutrients itself.
C. Stomach
Stomach plays a role in the digestion of proteins and the mechanical breakdown of food, but it absorbs very few nutrients, primarily alcohol and some drugs.
D. Large intestine
Large intestine absorbs water and electrolytes, but it is not the major site of nutrient absorption. Most nutrients are absorbed before food reaches the large intestine.

Which of the following constitutes the so-called bad cholesterol?
A. Triglycerides
Triglycerides are a type of fat found in the blood, but they are not classified as "bad cholesterol."
B. High-density lipoproteins
High-density lipoproteins (HDL) is known as "good cholesterol" because it helps remove cholesterol from the arteries.
C. Low-density lipoproteins
Low-density lipoproteins (LDL) are referred to as "bad cholesterol" because high levels of LDL can lead to the build-up of plaque in arteries, increasing the risk of heart disease and stroke.
D. Chylomicrons
Chylomicrons are lipoproteins that transport dietary lipids from the intestines to other locations in the body. They are not classified as "bad cholesterol."
