Final answer:
The statement that oxygen, nutrients, minerals, and wastes are carried in plasma is a) true. Plasma serves as the primary medium for transporting these substances throughout the body in blood vessels.
Step-by-step explanation:
True, oxygen, nutrients, minerals, and wastes are indeed carried in plasma. Plasma is the liquid component of blood and travels through the body in blood vessels, performing essential functions. It transports materials such as blood cells, proteins including clotting factors and antibodies, electrolytes, and dissolved gases necessary for bodily functions. Gases, nutrients, and waste materials travel between capillaries and cells through the interstitial fluid (IF). The cell membrane, which is selectively permeable, regulates the exchange of these substances between the IF and the cell's interior, ensuring proper cellular function and overall homeostasis.
