Breathing properly requires the presence of?
- A.
Potassium
- B.
Plasma
- C.
Surfactant
- D.
None
Correct Answer
C. SurfactantExplanation
Breathing properly requires the presence of surfactant. Surfactant is a substance that reduces surface tension in the alveoli of the lungs, allowing them to expand and contract easily during the breathing process. It also helps to prevent the collapse of the alveoli, ensuring efficient gas exchange. Without surfactant, the alveoli would be less flexible and more prone to collapse, leading to difficulties in breathing. Potassium and plasma are not directly involved in the process of breathing, and therefore are not necessary for it.Rate this question:

Which of the following is not a function of the kidney?
- A.
Secretion
- B.
Reabsorption
- C.
Transport
- D.
Filtration
Correct Answer
C. TransportExplanation
The kidney performs several important functions, including filtration, reabsorption, and secretion. Filtration refers to the process of removing waste products and excess water from the blood to form urine. Reabsorption involves the reabsorption of essential substances like water, glucose, and electrolytes back into the bloodstream. Secretion is the process of actively transporting certain substances, such as drugs and toxins, from the blood into the urine. However, transport is a broad term that can encompass both reabsorption and secretion, so it is not a distinct function of the kidney. Therefore, transport is not a function of the kidney.Rate this question:

What is the function unit of the kidney?
- A.
Medulla
- B.
Glomerulus
- C.
Pyramid
- D.
Nephron
Correct Answer
D. NephronExplanation
The function unit of the kidney is the nephron. Nephrons are responsible for filtering blood and producing urine. Each kidney contains millions of nephrons, which consist of a glomerulus and a tubule. The glomerulus filters waste products and excess water from the blood, while the tubule reabsorbs necessary nutrients and water back into the bloodstream, and excretes waste products as urine. Therefore, the nephron plays a crucial role in maintaining the body's fluid balance and removing waste products from the blood.Rate this question:
