Studdy Solution

STEP 1

1. Endocrine glands are glands that secrete their products (hormones) directly into the bloodstream.
2. Exocrine glands are glands that secrete their products into ducts that lead to the target tissue.
3. Each gland must be classified into one of these two categories based on their anatomical and functional characteristics.

STEP 2

1. Define characteristics of endocrine and exocrine glands.
2. Classify each gland based on its characteristics.

STEP 3

Define the characteristics of endocrine glands: - Endocrine glands release hormones directly into the bloodstream. - They do not have ducts. - Examples include glands like the pineal gland and adrenal gland.

STEP 4

Define the characteristics of exocrine glands: - Exocrine glands release their products through ducts to the target tissue. - They include glands like sweat glands and sebaceous glands.

STEP 5

Classify sweat glands: - Sweat glands secrete sweat through ducts to the surface of the skin. Therefore, sweat glands are exocrine glands.

STEP 6

Classify the pineal gland: - The pineal gland secretes melatonin directly into the bloodstream. Therefore, the pineal gland is an endocrine gland.

STEP 7

Classify sebaceous glands: - Sebaceous glands secrete sebum through ducts to the surface of the skin. Therefore, sebaceous glands are exocrine glands.

STEP 8

Classify the adrenal gland: - The adrenal gland secretes hormones like adrenaline directly into the bloodstream. Therefore, the adrenal gland is an endocrine gland.

STEP 9

Summarize the classification in the given table:
\begin{tabular}{|l|l|} \hline Exocrine Glands & Endocrine Glands \\ \hline Sweat glands, Sebaceous glands & Pineal gland, Adrenal gland \\ \hline \end{tabular}
