Final answer:
It is true that plasma contains water, proteins, nutrient molecules, and hormones. Plasma is essential for transporting various substances through the blood, including organic and inorganic constituents, and plays a critical role in maintaining homeostasis within the body.
Step-by-step explanation:
True, plasma contains water, proteins, nutrient molecules, and hormones. Plasma is more than half of blood by volume and consists of about 90% water. Within this fluid, plasma proteins such as albumin and globulins are suspended. Albumin, the most abundant plasma protein, plays a critical role in maintaining osmotic balance and blood pressure, while globulins are involved in transport and immunity. Other vital components in plasma include organic constituents like glucose, amino acids, and fatty acids, as well as inorganic constituents such as sodium, potassium, and chloride ions. Moreover, plasma carries hormones that regulate various physiological processes and metabolic waste products for excretion.
Among the plasma proteins, globulins, divided into alpha, beta, and gamma subgroups, serve different functions. Alpha and beta globulins transport nutrients and contribute to osmotic pressure, while gamma globulins act as antibodies part of the body's immune response.
