Which glands secrete their product into interstitial fluid or blood?Multiple choice question.HolocrineSudoriferousExocrineEndocrine

The glands that secrete their product into interstitial fluid or blood are the Endocrine glands.

Here's why:

1. Holocrine glands: These are a type of exocrine gland where the secreted product is released as a result of the destruction of the gland cell. They do not secrete their product into interstitial fluid or blood.

2. Sudoriferous glands: Also known as sweat glands, these are exocrine glands that secrete sweat onto the surface of the skin, not into interstitial fluid or blood.

3. Exocrine glands: These glands secrete their products through ducts onto epithelial surfaces, such as skin or the lumen of the gastrointestinal tract. They do not secrete their product into interstitial fluid or blood.

4. Endocrine glands: These glands secrete their products, hormones, directly into the interstitial fluid that surrounds them, and from there the hormones move into blood vessels to be transported throughout the body. Therefore, the correct answer is Endocrine glands.
