The heart is one of the most important _____ in the entire human body.
Correct Answer
organsExplanation
The heart is considered one of the most important organs in the entire human body because it plays a vital role in pumping oxygenated blood throughout the body. It is responsible for supplying oxygen and nutrients to all the cells and organs, ensuring their proper functioning. Without the heart, the body would not receive the necessary oxygen and nutrients, leading to organ failure and ultimately death. Thus, the heart is crucial for maintaining overall health and well-being.Rate this question:
- 11.
The heart is composed of ______ muscle which pumps blood throughout the body, beating approximately 72 times per minute of our lives.
Correct Answer
cardiacExplanation
The heart is composed of cardiac muscle which pumps blood throughout the body. Cardiac muscle is a specialized type of muscle found only in the heart. It is responsible for the rhythmic contractions that allow the heart to pump blood and circulate it to all parts of the body. These contractions occur approximately 72 times per minute, providing the necessary blood flow to deliver oxygen and nutrients to the body's tissues and organs.Rate this question:
- 12.
Muscles need ______, glucose for cellular respiration. The blood transports these materials to the muscles.
Correct Answer
oxygenExplanation
Muscles require oxygen for cellular respiration, which is the process that generates energy for muscle contraction. Oxygen is necessary for the breakdown of glucose, a type of sugar, in the muscle cells to produce ATP (adenosine triphosphate), the molecule that provides energy for various cellular activities. The blood carries oxygen from the lungs to the muscles, where it is used in cellular respiration.Rate this question:
- 13.
The upper chambers of the heart are known as the left and right ________.
Correct Answer
atrium , atriaExplanation
The upper chambers of the heart are called atrium and atria. The term "atrium" refers to a single upper chamber, while "atria" is the plural form of atrium, indicating both the left and right upper chambers of the heart.Rate this question:
- 14.
The heart contains _______ which allow blood to flow in only one direction through the heart.
Correct Answer
valvesExplanation
The heart contains valves which allow blood to flow in only one direction through the heart. Valves are thin flaps of tissue that open and close to control the flow of blood. They prevent the backflow of blood and ensure that blood moves forward through the heart chambers and into the blood vessels. The valves in the heart include the tricuspid valve, pulmonary valve, mitral valve, and aortic valve. These valves play a crucial role in maintaining the circulation of blood throughout the body.Rate this question:
- 15.
The main waste material from cellular respiration is called ________.
Correct Answer
carbon dioxideExplanation
During cellular respiration, glucose is broken down in the presence of oxygen to produce energy in the form of ATP. This process releases carbon dioxide as a waste product. Therefore, carbon dioxide is the main waste material from cellular respiration.Rate this question:
