Respiration is the process of the body taking oxygen (O2) in and removing carbon dioxide (CO2).
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Respiration is indeed the process by which the body takes in oxygen and removes carbon dioxide. During respiration, oxygen is inhaled into the lungs and transported to the body's cells, where it is used to produce energy. Carbon dioxide, which is a waste product of this energy production, is then carried back to the lungs and exhaled. This continuous exchange of oxygen and carbon dioxide is vital for the body's functioning and is a fundamental process in all living organisms. Therefore, the statement "Respiration is the process of the body taking oxygen in and removing carbon dioxide" is true.Rate this question:

Gas exchange is the process where oxygen enters the blood from alveoli during inspiration. At the same time carbon dioxide crosses from blood to alveoli to be exaled (expiration) from the body.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Gas exchange is a vital process in the respiratory system where oxygen is taken in from the alveoli into the blood during inspiration, while carbon dioxide is released from the blood into the alveoli to be exhaled during expiration. This process ensures that oxygen is delivered to the body's tissues and carbon dioxide, a waste product, is removed from the body. Therefore, the statement is true.Rate this question:
-

During exercise, there is no major change in respiration rates of healthy young people.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
During physical activity and exercise, the body has a higher demand for oxygen, triggering an increase in respiration rates (breathing), increasing volume of air moving into and out of the lungs, increasing oxygen to blood and increasing waste removal.Rate this question:
-
- 7.
Our respiration rates can increase just at the thought of doing physical activity/exercise.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The statement is true because our respiration rates can increase even when we think about doing physical activity or exercise. This is because our brain sends signals to our respiratory system to prepare for the upcoming physical exertion. These signals stimulate the respiratory muscles, causing an increase in respiration rate and depth to ensure that our body receives enough oxygen during exercise. Therefore, the thought of physical activity can trigger a physiological response in our respiratory system.Rate this question:
-

The heart has a rhythmic contraction and relaxation process. This is diastole (relaxation/filling) and systole (contracting/pumping) phase.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The statement is true because the heart does indeed have a rhythmic contraction and relaxation process. This process is known as the cardiac cycle, which consists of two phases: diastole and systole. During diastole, the heart relaxes and fills with blood. During systole, the heart contracts and pumps the blood out to the rest of the body. This rhythmic cycle allows for the continuous circulation of blood throughout the body.Rate this question:

The right side of the heart only deals with de-oxygenated blood while the left side of the heart only deals with oxgenated blood.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The statement is true because the right side of the heart receives deoxygenated blood from the body and pumps it to the lungs for oxygenation. The left side of the heart receives oxygenated blood from the lungs and pumps it to the rest of the body. This separation of oxygenated and deoxygenated blood ensures that oxygen-rich blood is delivered to the body's tissues and organs, while deoxygenated blood is returned to the lungs for oxygenation.Rate this question:
-
- 23.
The right side of the heart receives deoxygenated blood from all parts of the body and pumps it to the lungs (where it picks up oxygen) and then back to the heart. This is called systemic circulation.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
FALSE - blood being pumped from the heart to the lungs and back to the heart is called PULMONARY circulation.Rate this question:
-
- 24.
Systemic circulation is the flow of blood from the heart to the body and then back to the heart.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The explanation for the given correct answer is that systemic circulation refers to the pathway of blood flow from the heart to the rest of the body's tissues and organs, delivering oxygen and nutrients, and then returning deoxygenated blood back to the heart. This process is essential for maintaining the body's overall function and is facilitated by a network of blood vessels, including arteries, capillaries, and veins. Therefore, it is accurate to say that systemic circulation involves the flow of blood from the heart to the body and then back to the heart.Rate this question:

The left side of the heart receives blood high in oxygen content (oxygenated) from the lungs and pumps it around the body.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The left side of the heart is responsible for receiving oxygenated blood from the lungs and pumping it to the rest of the body. This is true because after the blood is oxygenated in the lungs, it is returned to the left side of the heart through the pulmonary veins. From there, it is pumped out to the body through the aorta, supplying oxygen to the tissues and organs.Rate this question:

-
- 27.
Blood pressure has two phases - systolic pressure is the pressure when blood is forced into the arteries during contraction of the left ventricle and diastolic pressure when the heart is relaxing or filling. Systolic pressure is always a higher number (120 / 80 is normal blood pressure. Systolic is the 120).
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Blood pressure has two phases - systolic pressure and diastolic pressure. Systolic pressure is the pressure when blood is forced into the arteries during contraction of the left ventricle, while diastolic pressure is when the heart is relaxing or filling. Since systolic pressure is the higher number in a blood pressure reading, it is true that systolic pressure is always a higher number.Rate this question:

Smoking causes tiny air sacs called alveoli to deterioriate and 'rot' away leading to an inability to breath effectively.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Smoking causes damage to the tiny air sacs called alveoli in the lungs, leading to their deterioration and ultimately causing them to 'rot' away. This damage impairs the ability to breathe effectively, as the alveoli are responsible for the exchange of oxygen and carbon dioxide in the lungs. Therefore, it is true that smoking can lead to an inability to breathe effectively.Rate this question:
