2.

The liver, stomach, mouth, and pancreas are in the ___________ system.

Reproductive
Sensory
Digestive
Muscular

Correct Answer

A. Digestive

Explanation

The liver, stomach, mouth, and pancreas are all organs involved in the process of digestion. They work together to break down food, absorb nutrients, and eliminate waste. Therefore, these organs belong to the digestive system.

3.

The heart, lymphatic organs, and blood vessels are in the ________ system.

Respiratory
Cardiovascular
Digestive
Urinary

Correct Answer

A. Cardiovascular

Explanation

The heart, lymphatic organs, and blood vessels are all part of the cardiovascular system. This system is responsible for the circulation of blood throughout the body, delivering oxygen and nutrients to tissues and organs. The heart acts as the pump, while the blood vessels transport the blood. The lymphatic organs, such as the spleen and lymph nodes, are also part of this system as they play a role in immune function and fluid balance. Therefore, the correct answer is cardiovascular.

The most important step to ensure accuracy in sample collection is ____________.

Recording the time accurately
By always wearing gloves
Keeping the patient supine
Identifying the patient properly

Correct Answer

A. Identifying the patient properly

Explanation

Identifying the patient properly is the most important step to ensure accuracy in sample collection. This is because collecting samples from the wrong patient can lead to incorrect diagnoses and treatment, potentially causing harm to the patient. Proper identification ensures that the sample is collected from the intended individual, reducing the risk of errors and ensuring accurate results.

Characteristics of capillaries include _________.

Having thin-walls
Forming microscopic pathways
Connecting aterioles with venules
All of the above

Correct Answer

A. All of the above

Explanation

Capillaries have thin walls, forming microscopic pathways that connect arterioles with venules. This means that all of the given characteristics are true for capillaries. They have thin walls to allow for the exchange of gases and nutrients between the blood and surrounding tissues. Being microscopic in size, they form a vast network throughout the body, ensuring that every cell is supplied with oxygen and nutrients while waste products are removed. Additionally, capillaries connect arterioles (small arteries) with venules (small veins), facilitating the flow of blood between the arterial and venous systems.

The forearm bein most commonly used for venipuncture is the ________.

Median cubital
Basilic
Cephalic
Radial

Correct Answer

A. Median cubital

Explanation

The forearm is the most commonly used area for venipuncture because it contains the median cubital vein. This vein is located in the middle of the forearm and is easily accessible, making it an ideal choice for drawing blood or administering intravenous medications. The basilic, cephalic, and radial veins are also present in the forearm, but the median cubital vein is preferred due to its larger size and stability, reducing the risk of complications during the procedure.

The smallest veins in the human body are known as ________.

Villi
Bronchioles
Venules
Lymph glands

Correct Answer

A. Venules

Explanation

Venules are the smallest veins in the human body. Veins are blood vessels that carry deoxygenated blood back to the heart. Venules are the smallest branches of veins and they connect the capillaries to the larger veins. They play a crucial role in the circulation of blood, allowing the exchange of nutrients and waste products between the tissues and the bloodstream.

8.

Within the capillaries, blood cell functions include ________.

Releasing oxygen
Binding carbon dioxide
Eliminating waste
All of the above

Correct Answer

A. All of the above

Explanation

Within the capillaries, blood cell functions include releasing oxygen, binding carbon dioxide, and eliminating waste. Oxygen is released from red blood cells to be delivered to tissues, while carbon dioxide is bound by red blood cells to be transported back to the lungs for elimination. Additionally, waste products such as metabolic byproducts and toxins are also eliminated through the capillaries. Therefore, all of the given options are correct.

The suffix -URIA at the end of a medical term refers to what body location?

Blood stream
Urine
Kidney
Synovial fluid

Correct Answer

A. Urine

Explanation

The suffix -URIA in a medical term refers to urine. The term is used to indicate a condition or presence of something in the urine. For example, hematuria refers to the presence of blood in the urine, and proteinuria refers to the presence of protein in the urine. Therefore, the correct answer is urine.

The aorta branches into smaller divisions called arteries, which in turn branch into even smaller divisions called __________.

Capillaries
Arterioles
Venules
Lymph glands

Correct Answer

A. Arterioles

Explanation

The aorta, the largest artery in the body, branches into smaller divisions called arteries. These arteries further divide into even smaller divisions called arterioles. Arterioles are responsible for delivering oxygenated blood to the capillaries, which are the smallest blood vessels in the body. Therefore, arterioles are the correct answer as they are the immediate smaller divisions of arteries.
