Respiratory And Circulatory System Review Quiz

Explanation
The circulatory system (also called cardiovascular system) relates to heart and blood vessels.

Explanation
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.

Explanation
Inspiration is when we breathe in bring air from the atmosphere into the lungs.

Explanation
Oxygen binds to haemoglobin in red blood cells.

Explanation
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.

Explanation
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.

Explanation
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.

Explanation
Of course it does!!

Explanation
Heart, blood and blood vessels.

Explanation
The circulatory system plays a crucial role in distributing blood throughout the body. Blood carries oxygen and nutrients to various organs and tissues, ensuring their proper functioning. Additionally, the circulatory system collects carbon dioxide and waste products from cells and transports them to the lungs and kidneys for elimination. Therefore, it can be concluded that the main role of the circulatory system is indeed to distribute blood containing oxygen, nutrients, and collect and remove carbon dioxide and waste.

Explanation
Arteries, veins and capillaries.

Explanation
Carbon dioxide will kill you if it is not removed by the body.

Explanation
The statement is true because plasma does indeed make up 55% of blood, while the other 45% is composed of red and white blood cells, as well as platelets. Plasma is the liquid component of blood that carries nutrients, hormones, and waste products throughout the body. Red blood cells are responsible for carrying oxygen, while white blood cells help to fight off infections, and platelets aid in blood clotting. Therefore, the given answer is true.

Explanation
White blood cells are formed in bone marrow and are the body's defence system protecting against disease and infection (body's immune system). PLATELETS produce substances for blood clotting.

Explanation
False - there are 700 red blood cells to every 1 white blood cell

Explanation
The statement is true because the heart is indeed a muscular pump that is slightly larger than a clenched fist. It is responsible for pumping blood throughout the body, providing enough force to keep the blood circulating.

Explanation
ARTERIES carry blood AWAY from the heart and have strong, elastic artery walls. Veins have VAVES and carry blood back to the heart.

Explanation
Other way around - Arteries carry oxgenated (oxygen rich blood) from the heart to all the muscles while veins carry deoxygenated blood, carbon dioxide, waste back to the heart, then lungs where it is exhaled (removed from the body)

Explanation
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.

Explanation
The left ventricle is the strongest chamber of the heart which pumps blood all around the body. The right atrium pumps deoxygenated blood to the lungs where it is picks ups fresh oxygen (becomes oxygenated).

Explanation
Capillaries are indeed the link between arteries and veins, and their thin walls allow for efficient gas exchange. Oxygen and nutrients are transported to cells and muscles through capillaries, while carbon dioxide and waste products are collected by the capillaries and carried to veins for elimination. Therefore, the statement is true.

Explanation
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.

Explanation
FALSE - blood being pumped from the heart to the lungs and back to the heart is called PULMONARY circulation.

Explanation
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.

Explanation
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.

Explanation
Blood pressure is the pressure that the blood exerts on the blood vessels.

Explanation
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.

Explanation
A sphygmomanometer is used to measure blood pressure.

Explanation
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.

Explanation
Measured in beats per minute (BPM)
