The Human Body: Trivia Facts And Questions On Anatomy And Functions!

2.

A collection of glands that secrete chemical messages called hormones. The hormones pass through the blood to the target organ resulting in a chemical change in the body.

Liver
Endocrine System
Gall Bladder
Kidneys

Correct Answer

A. Endocrine System

Explanation

The endocrine system is a collection of glands that secrete hormones, which are chemical messages. These hormones are transported through the bloodstream to target organs, where they cause chemical changes in the body. The liver, gall bladder, and kidneys are not part of the endocrine system, so they do not secrete hormones or have the same role in regulating bodily functions.

A small, pear-shaped muscular sac, located under the right lobe of the liver, in which bile secreted by the liver is stored until needed by the body for digestion.

Small Intestine
Liver
Kidneys
Gall Bladder

Correct Answer

A. Gall Bladder

Explanation

The correct answer is Gall Bladder. The gall bladder is a small, pear-shaped muscular sac that is located under the right lobe of the liver. Its main function is to store bile that is secreted by the liver until it is needed by the body for digestion. Bile helps in the breakdown of fats in the small intestine.

A pair of organs functioning to maintain proper water and electrolyte balance, regulate acid-base concentration and filter the blood of metabolic wastes, which are then excreted as urine.

Kidneys
Lungs
Gall Bladder
Pancreas

Correct Answer

A. Kidneys

Explanation

The kidneys are responsible for maintaining proper water and electrolyte balance, regulating acid-base concentration, and filtering the blood of metabolic wastes. These wastes are then excreted as urine. The lungs are primarily responsible for gas exchange and not for maintaining water and electrolyte balance or filtering the blood. The gall bladder stores bile produced by the liver and the pancreas produces digestive enzymes and hormones, but neither organ is directly involved in maintaining water and electrolyte balance or filtering the blood. Therefore, the correct answer is kidneys.

Beginning with the cecum and ending with the rectum; includes the cecum and the colon and the rectum; extracts moisture from food residues which are later excreted as feces

Stomach
Small Intestine
Large Intestine
Pancreas

Correct Answer

A. Large Intestine

Explanation

The large intestine is responsible for extracting moisture from food residues, which are then excreted as feces. It begins with the cecum, includes the colon, and ends with the rectum. The large intestine plays a crucial role in the digestive process by absorbing water and electrolytes from the remaining undigested food, forming solid waste that is eventually eliminated from the body. The stomach is responsible for initial digestion, the small intestine is where most nutrient absorption occurs, and the pancreas produces digestive enzymes and hormones.

A large, reddish-brown, organ located in the upper right portion of the abdominal cavity that secretes bile and is active in the formation of certain blood proteins and in the metabolism of carbohydrates, fats, and proteins

Liver
Nervous System
Endocrine System
Stomach

Correct Answer

A. Liver

Explanation

The correct answer is liver. The liver is a large, reddish-brown organ located in the upper right portion of the abdominal cavity. It has multiple functions, including the secretion of bile, which aids in digestion, and the formation of certain blood proteins. The liver is also involved in the metabolism of carbohydrates, fats, and proteins.

Either of two spongy, saclike respiratory organs in most vertebrates, occupying the chest cavity together with the heart and functioning to remove carbon dioxide from the blood and provide it with oxygen.

Lungs
Kidneys
Liver
Endocrine System

Correct Answer

A. Lungs

Explanation

The correct answer is lungs. Lungs are spongy, saclike respiratory organs found in most vertebrates. They are located in the chest cavity along with the heart. Lungs play a crucial role in the respiratory system by removing carbon dioxide from the blood and providing it with oxygen. They are responsible for the exchange of gases between the body and the environment, allowing for the process of respiration to occur.

The system of cells, tissues, and organs that regulates the body's responses to internal and external stimuli. Invertebrates, it consists of the brain, spinal cord, nerves, ganglia, and parts of the receptor and effector organs.

Lungs
Endocrine System
Nervous System
Kidneys

Correct Answer

A. Nervous System

Explanation

The nervous system is responsible for regulating the body's responses to internal and external stimuli. It consists of the brain, spinal cord, nerves, ganglia, and parts of the receptor and effector organs. This system allows for the transmission of signals between different parts of the body, allowing for coordination and control of bodily functions. The other options listed (lungs, endocrine system, kidneys) are not involved in regulating responses to stimuli in the same way as the nervous system.

A long, irregularly shaped gland in vertebrates, lying behind the stomach, that secretes pancreatic juice into the duodenum and insulin, glucagon, and somatostatin into the bloodstream.

Gall Bladder
Liver
Pancreas
Lungs

Correct Answer

A. Pancreas

Explanation

The correct answer is Pancreas. The pancreas is a long, irregularly shaped gland located behind the stomach in vertebrates. It has multiple functions, including secreting pancreatic juice into the duodenum to aid in digestion, as well as producing and releasing insulin, glucagon, and somatostatin into the bloodstream. These hormones play a crucial role in regulating blood sugar levels and metabolism. The pancreas is not directly involved in the production or storage of bile, which is the main function of the gall bladder, or in the filtration and detoxification of blood, which is the main function of the liver. The lungs are responsible for respiration and are not related to the functions described in the question.

The upper portion of the bowel, in which the process of digestion is practically completed. It is narrow and contorted and consists of three parts, the duodenum, jejunum, and ileum.

Large Intestine
Small Intestine
Liver
Pancreas

Correct Answer

A. Small Intestine

Explanation

The correct answer is small intestine because it is the upper portion of the bowel where the process of digestion is practically completed. It is narrow and contorted and consists of three parts, the duodenum, jejunum, and ileum. The small intestine is responsible for absorbing nutrients from the digested food and transferring them into the bloodstream for distribution throughout the body.

The enlarged, saclike canal, one of the principal organs of digestion, located between the esophagus and the small intestine.

Endocrine System
Liver
Pancreas
Stomach

Correct Answer

A. Stomach

Explanation

The correct answer is stomach because it is an enlarged, saclike canal that is one of the principal organs of digestion. It is located between the esophagus and the small intestine. The stomach plays a crucial role in the digestion process by breaking down food with the help of digestive enzymes and acids.
