Question

The network of glands that releases hormones into the bloodstream is the _____ system.

a. endocrine
b. autonomic
c. exocrine
d. nervous

Answer 1

The endocrine system is the network of glands that releases hormones into the bloodstream, crucial for regulating vital body functions and maintaining homeostasis. Endocrine glands, including the pituitary gland, secrete hormones directly into the blood, differentiating them from exocrine glands. The correct answer is option a. endocrine.

Step-by-step explanation:

The network of glands that releases hormones into the bloodstream is the endocrine system. This system includes a variety of glands known as endocrine glands, which secrete hormones. These hormones are crucial for regulating many bodily functions, including metabolism, growth, and sexual development.

The pituitary gland, often referred to as the 'master gland', plays a pivotal role in controlling the activity of other endocrine glands. Hormones are diffused into the bloodstream from the glands and travel to target cells throughout the body. Unlike exocrine glands, which secrete substances through ducts, the secretions from endocrine glands enter directly into the blood, enabling them to circulate widely and affect multiple organ systems.

Some other notable endocrine glands include the pancreas, which not only aids in digestion but also controls blood glucose levels, and the thyroid gland, which regulates metabolism. Adrenal glands play a crucial role in stress response, while the gonads (such as the ovaries and testes) are vital for reproductive functions. The endocrine system works in concert with the nervous system to maintain homeostasis and respond to various physiological demands and environmental changes.

The correct answer to the question 'The network of glands that releases hormones into the bloodstream is the _____ system' is option a. endocrine.

Answer 2

The network of glands that releases hormones into the bloodstream is known as the endocrine system. Endocrine glands release hormones directly into the bloodstream to regulate body functions, with the pituitary gland being the master gland overseeing this system.

Step-by-step explanation:

The Network of Glands Releasing Hormones

The network of glands that releases hormones into the bloodstream is the endocrine system. Hormones are chemical messengers that control various body functions including metabolism, growth, and sexual development.

Unlike exocrine glands, which secrete substances to nearby surfaces through ducts, the endocrine glands release hormones directly into the interstitial fluid, which then diffuses into the bloodstream. The pituitary gland, known as the master gland, produces hormones that regulate other endocrine glands throughout the body. Some of the other endocrine glands include the pancreas, thyroid gland, and adrenal glands.

Each hormone has specific target cells that have receptors to bind the hormone and elicit a response. This complex system is crucial for maintaining homeostasis and is under the regulation of the hypothalamus, which is a part of the brain that coordinates the activity of the endocrine system with the nervous system.
