Anatomy And Physiology Questions and Answers
- 1.
Which system in the human body is responsible for transporting blood?
- A.
Nervous system
- B.
Digestive system
- C.
Circulatory system
- D.
Respiratory system
Correct Answer
C. Circulatory systemExplanation
The circulatory system, also known as the cardiovascular system, is responsible for transporting blood throughout the body. It consists of the heart, blood vessels, and blood. The heart pumps oxygenated blood to the tissues and organs and returns deoxygenated blood to the lungs for re-oxygenation.Rate this question:

What is the basic functional unit of the kidney?
- A.
Neuron
- B.
Alveolus
- C.
Nephron
- D.
Osteon
Correct Answer
C. NephronExplanation
The nephron is the basic functional unit of the kidney. Each kidney contains approximately one million nephrons, which filter blood to remove waste products and excess substances, producing urine. Nephrons play a crucial role in maintaining the body's fluid and electrolyte balance.Rate this question:

Which cells are responsible for carrying oxygen in the blood?
- A.
White blood cells
- B.
Platelets
- C.
Red blood cells
- D.
Plasma cells
Correct Answer
C. Red blood cellsExplanation
Red blood cells (erythrocytes) are responsible for carrying oxygen from the lungs to the body's tissues and organs and transporting carbon dioxide back to the lungs for exhalation. Hemoglobin, a protein in red blood cells, binds to oxygen and facilitates its transport.Rate this question:
