Which is the four chambered muscular organ which includes the right and left ventricles and the right and left auricle?
- A.
Spleen
- B.
Heart
- C.
Liver
Correct Answer
B. HeartExplanation
The correct answer is heart. The heart is a four-chambered muscular organ that consists of the right and left ventricles and the right and left auricles. The ventricles are responsible for pumping oxygenated and deoxygenated blood to different parts of the body, while the auricles receive blood from the veins and transfer it to the ventricles. The heart plays a crucial role in the circulatory system, ensuring the proper flow of blood throughout the body.Rate this question:

Breathing in and out is known as what?
- A.
Respiration
- B.
Inhalation
- C.
Expiration
Correct Answer
A. RespirationExplanation
Breathing in and out is known as respiration. Respiration refers to the process of inhaling and exhaling, which allows oxygen to enter the body and carbon dioxide to be expelled. It is a vital process that provides the necessary oxygen for cellular respiration, where energy is produced in the form of ATP. Inhalation and expiration are specific phases of the respiration process, with inhalation being the act of breathing in and expiration being the act of breathing out. However, respiration encompasses both of these actions.Rate this question:

What are the organs of respiration?
- A.
The kidneys
- B.
The lungs
- C.
The nose and mouth
Correct Answer
B. The lungsExplanation
The lungs are the main organs of respiration. They are responsible for the exchange of oxygen and carbon dioxide between the air and the bloodstream. The lungs have a large surface area and are made up of tiny air sacs called alveoli, where the exchange of gases takes place. When we breathe in, oxygen enters the lungs and is transported to the cells of the body. At the same time, carbon dioxide, a waste product of cellular respiration, is removed from the body through exhalation. The kidneys, on the other hand, are responsible for filtering waste products from the blood and producing urine. The nose and mouth play a role in the process of breathing by allowing air to enter and exit the respiratory system.Rate this question:

A. On left side of chest between 5th & 8th ribsExplanation
The heart is located on the left side of the chest between the 5th and 8th ribs. This is the correct answer because the heart is a vital organ that is situated in the thoracic cavity, specifically in the mediastinum. It is slightly tilted to the left and its apex is positioned towards the left side of the chest. The 5th to 8th ribs provide protection to the heart, and this location allows for efficient pumping of blood to the rest of the body.Rate this question:
