The substances transported by blood include:

a. Nutrients - Yes, nutrients are transported by blood. After digestion, nutrients are absorbed into the bloodstream to be delivered to cells throughout the body.

d. Hormones - Yes, hormones are transported by blood. The endocrine system uses the circulatory system to transport hormones to various parts of the body.

f. Heat, body temperature - Yes, blood helps distribute heat throughout the body, helping to maintain a consistent body temperature.

h. Gases - Yes, gases like oxygen and carbon dioxide are transported by blood. Oxygen is delivered to cells for cellular respiration, and carbon dioxide, a waste product of cellular respiration, is carried back to the lungs to be exhaled.
