Which of the following exercises is best for increasing heart and lung endurance?
Correct Answer
B. Swimming
Explanation
Swimming is the best exercise for increasing heart and lung endurance because it is a cardiovascular exercise that engages the entire body. It requires continuous movement and uses large muscle groups, which increases heart rate and oxygen intake. Swimming also provides resistance, making the heart and lungs work harder to supply oxygen to the muscles. Additionally, the buoyancy of water reduces impact on joints, making it suitable for people of all fitness levels. Overall, swimming is an excellent choice for improving cardiovascular fitness and endurance.

In pulmonary circulation, blood flows from the .....
Correct Answer
A. Heart to the lungs to the heart
Explanation
In pulmonary circulation, blood flows from the heart to the lungs to the heart. This is because the right side of the heart pumps deoxygenated blood to the lungs through the pulmonary artery. In the lungs, the blood picks up oxygen and releases carbon dioxide through the process of gas exchange. The oxygenated blood then returns to the left side of the heart through the pulmonary veins, completing the circulation.
3.
Blood does all of the following EXCEPT
Correct Answer
B. Remove carbon dioxide from the lungs
Explanation
Blood performs several important functions in the body, including delivering oxygen to body parts, delivering vitamins to cells, and promoting healing by clotting at wounds. However, blood does not remove carbon dioxide from the lungs. This task is primarily carried out by the respiratory system, specifically the lungs, which expel carbon dioxide during exhalation.
4.
Over half of the volume of blood is made up of
Correct Answer
A. Plasma
Explanation
Plasma is the correct answer because it makes up over half of the volume of blood. Plasma is a yellowish fluid that carries various substances such as nutrients, hormones, waste products, and antibodies throughout the body. It also helps maintain blood pressure and plays a crucial role in clotting. While red blood cells, platelets, and white blood cells are all important components of blood, they do not make up the majority of its volume.
5.
Bones do all of the following EXCEPT
Correct Answer
D. Supply oxygen to the blood
Explanation
Bones are responsible for many functions in the body, including storing calcium, making new blood cells, and supporting the body frame. However, bones do not have the capability to supply oxygen to the blood. This task is performed by the respiratory system, specifically the lungs, where oxygen is taken in and transported to the blood through the process of respiration. Therefore, the correct answer is that bones do not supply oxygen to the blood.
6.
Which of the following describes the movement of a ball-and-socket joint?
Correct Answer
D. Can move in all directions
Explanation
A ball-and-socket joint is a type of joint that allows movement in multiple directions. It consists of a rounded bone (the ball) that fits into a cup-like socket, allowing for a wide range of motion. This joint enables movement not only up and down and from side to side but also rotationally, making it capable of moving in all directions.
7.
Which of the following is an accurate statement about the way muscles work?
Correct Answer
A. Pairs of skeletal muscles work in opposition to move bones.
Explanation
Pairs of skeletal muscles work in opposition to move bones. This statement accurately describes the way muscles work. Skeletal muscles are attached to bones by tendons and work in pairs called antagonistic pairs. When one muscle in the pair contracts, the other muscle relaxes, allowing movement to occur. This opposing action is what enables the movement of bones in our body.
8.
Workout sessions should always include
Correct Answer
A. A warm-up
Explanation
A warm-up is an essential part of any workout session as it helps prepare the body for physical activity. It involves performing low-intensity exercises or movements that gradually increase heart rate, blood flow, and body temperature. This helps loosen up muscles, increase flexibility, and reduce the risk of injury during the main workout. Warm-ups also mentally prepare individuals for the upcoming physical activity and enhance overall performance. Therefore, including a warm-up in workout sessions is crucial for maximizing the benefits of exercise and ensuring safety.

Look at the Diagram above. What is Label #6?
Correct Answer
B. Mandible
Explanation
Label #6 in the diagram is the mandible. The mandible is commonly known as the jawbone and is the largest and strongest bone in the human face. It forms the lower jaw and plays a crucial role in various functions such as chewing, speaking, and facial expression.
10.
What is Number 3?
Correct Answer
C. Spinal Cord
Explanation
The question is asking for the identification of "Number 3," and the correct answer is "Spinal Cord." This suggests that "Number 3" refers to the spinal cord. The other options, "Brain Stem" and "Cord," do not accurately correspond to the given answer.
11.
What is # 7
Correct Answer
B. Right Atrium
Explanation
The correct answer is the Right Atrium. The question is asking about "What is #7," and the options provided are different parts of the heart. Out of the given options, the Right Atrium is the only one that corresponds to the number 7.
12.
What is # 11
Correct Answer
B. Valves
Explanation
Valves are devices used to control the flow of fluids or gases. They can open, close, or partially obstruct the passage of the fluid or gas through pipes or channels. In this context, the question is asking for the definition of "#11," and out of the given options, valves are the most relevant as they are commonly associated with controlling the flow of fluids or gases.
13.
What is #11?
Correct Answer
B. pHalanges
Explanation
The correct answer is Phalanges. Phalanges are the bones in the fingers and toes. They are long, slender bones that make up the digits of the hand and foot. The other options listed, such as scapula and tibia, are bones found in other parts of the body and are not directly related to the question of what #11 is.
14.
What is #12?
Correct Answer
D. Femur
Explanation
The femur is the correct answer because it is commonly known as the thigh bone. It is the largest and strongest bone in the human body and is located in the upper leg. The fibula and tibia are also bones in the leg, but they are not commonly referred to as the thigh bone. Therefore, the femur is the most appropriate answer for the question.
15.
What is #1
Correct Answer
A. Cranium
Explanation
The cranium is the correct answer because it refers to the part of the skull that encloses and protects the brain. It is made up of several bones and forms the top, back, and sides of the skull. The other options, such as skull, frontal plate, and head, are related to the cranium but do not specifically refer to the entire structure. Therefore, the cranium is the most accurate and specific answer in this context.
