B. False
Explanation
IT takes at least 24 hours for the food to get out of small intestine and into the large intestine but depending on what it is is how long it takes. :)
6.
Where do the protiens start to break down at?
Correct Answer
A. Stomach
Explanation
Proteins start to break down in the stomach. The stomach secretes gastric juice, which contains hydrochloric acid and enzymes such as pepsin. Pepsin breaks down proteins into smaller peptides. This initial breakdown in the stomach is crucial for further digestion and absorption of proteins in the small intestine.
7.
What does Salivary Amylase do?
Correct Answer
B. Breaks down food and gives it a sugary taste
Explanation
Salivary amylase is an enzyme found in saliva that breaks down starches and complex carbohydrates into simple sugars. This process is known as digestion and it allows for the absorption of nutrients from the food we consume. The breakdown of food by salivary amylase also contributes to the taste of food, as the conversion of starches into sugars can give it a sweet or sugary taste.
8.
Where is the Diaphram located?
Correct Answer
A. Under the lungs and above the rib cage
Explanation
The diaphragm is a dome-shaped muscle located under the lungs and above the rib cage. It separates the thoracic cavity, where the heart and lungs are located, from the abdominal cavity. When the diaphragm contracts, it flattens and moves downward, allowing the lungs to expand and fill with air during inhalation. When it relaxes, the diaphragm moves back up, helping to push air out of the lungs during exhalation.
9.
You have two tubes in throat that lead to the stomach and to the lungs.
Correct Answer
A. True
Explanation
The statement is true because the human body has two tubes in the throat known as the esophagus and the trachea. The esophagus connects the throat to the stomach, allowing food and liquids to pass through for digestion. On the other hand, the trachea leads to the lungs, allowing air to pass through for respiration. These two separate tubes serve different functions and are essential for the proper functioning of the digestive and respiratory systems.
10.
When you breath in your diaphram moves outward.
Correct Answer
B. False
Explanation
When you breathe in, your diaphragm actually moves downward, not outward. This downward movement creates more space in your chest cavity, allowing your lungs to expand and fill with air. So, the statement "When you breathe in your diaphragm moves outward" is incorrect.
11.
What is the Larynx?
Correct Answer
B. The voice box
Explanation
The larynx is commonly known as the voice box. It is a part of the respiratory system located in the throat. Its main function is to produce sound and aid in vocalization. The larynx contains the vocal cords, which vibrate to produce sound when air passes through them. It also plays a crucial role in preventing food and liquid from entering the airway during swallowing.
12.
What does the escretory system do?
Correct Answer
D. All of the above
Explanation
The excretory system is responsible for getting rid of waste from the body, preventing harmful chemical buildups, and maintaining a steady balanced chemical concentration. It accomplishes this through various organs such as the kidneys, liver, and lungs. These organs filter waste products, regulate fluid and electrolyte balance, and remove toxins from the body. By performing all of these functions, the excretory system ensures the proper functioning and overall health of the body.
13.
What does the respritory system work?
Correct Answer
A. Supplies the blood with oxygen
Explanation
The respiratory system works by supplying the blood with oxygen. Oxygen is inhaled through the nose or mouth, travels down the trachea, and enters the lungs. In the lungs, oxygen is transferred to the bloodstream through tiny blood vessels called capillaries. This oxygen-rich blood is then pumped by the heart to the rest of the body, providing oxygen to the cells and tissues for their proper functioning.
14.
What does the circulatory system do?
Correct Answer
A. Controls blood flow throughout the body
Explanation
The circulatory system is responsible for controlling the flow of blood throughout the body. It consists of the heart, blood vessels, and blood cells. The heart pumps oxygenated blood to various parts of the body through arteries, and then collects deoxygenated blood through veins to be sent back to the lungs for oxygenation. This continuous circulation ensures that oxygen and nutrients are delivered to all cells in the body and waste products are removed. Therefore, the circulatory system plays a vital role in maintaining the overall functioning of the body.
15.
The main parts of the Circulatory system are
Correct Answer
A. Heart, arteries, capillaries and veins
Explanation
The circulatory system consists of the heart, arteries, capillaries, and veins. The heart pumps oxygenated blood to the body through arteries, which then branch into smaller vessels called capillaries. Capillaries allow for the exchange of oxygen and nutrients with body tissues. Deoxygenated blood is then carried back to the heart through veins, completing the circulation process. This answer accurately lists all the main components of the circulatory system.
16.
The Lymphatic system helps protect your body from diseases.
Correct Answer
A. True
Explanation
The lymphatic system is a network of vessels, nodes, and organs that plays a crucial role in the body's immune defense. It helps to transport lymph, a fluid containing white blood cells, throughout the body, filtering out harmful substances and pathogens. The lymphatic system also helps to remove waste products and toxins from the body. By performing these functions, the lymphatic system aids in protecting the body from diseases and maintaining overall health. Therefore, the statement "The lymphatic system helps protect your body from diseases" is true.
17.
The Muscle types in the muscular systems are?
Correct Answer
D. All
Explanation
The correct answer is "all" because the muscular system consists of three types of muscles: cardiac, smooth, and skeletal. Cardiac muscles are found in the heart and are responsible for pumping blood. Smooth muscles are found in the walls of organs and blood vessels and control involuntary movements. Skeletal muscles are attached to bones and are responsible for voluntary movements. Therefore, "all" is the correct answer as it includes all three types of muscles present in the muscular system.
