Let's go through each term and find the correct match for the descriptions given:
1.1 A gland whose secretions are transported through blood streams.
Endocrine Gland: Endocrine glands release hormones directly into the bloodstream.
1.2 A system that is responsible for chemical coordination in the body.
Endocrine System: This system includes glands that produce hormones which regulate metabolism, growth, development, tissue function, sexual function, reproduction, sleep, and mood.
1.3 A hormone that stimulates ovulation in humans.
Luteinizing Hormone (LH): LH triggers ovulation in females.
1.4 The process of maintaining a constant internal environment in the human body.
Homeostasis: This process helps to maintain stable internal conditions despite changes in external environments.
1.5 A gland whose secretions are transported through ducts.
Exocrine Gland: Exocrine glands secrete their products through ducts.
1.6 A hormone that stimulates mammary gland to produce milk.
Prolactin: This hormone plays an important role in milk production.
1.7 A hormone that is responsible for osmoregulation in the body.
Antidiuretic Hormone (ADH): ADH helps control water balance in the body.
1.8 Specialized cells in the pancreas that secrete insulin and glucagon.
Islets of Langerhans: These are clusters of cells in the pancreas that include alpha cells (secreting glucagon) and beta cells (secreting insulin).
1.9 A hormone responsible for secondary sexual characteristics in males.
Testosterone: This is responsible for the development of male secondary sexual features.
1.10 A hormone that is responsible for maintaining salt balance in the blood.
Aldosterone: Aldosterone helps regulate sodium and potassium levels in the body.
1.11 A gland that secretes FSH and LH in females.
Pituitary Gland: This gland is located at the base of the brain and secretes several key hormones including FSH and LH.
1.12 Chemical messengers produced by endocrine glands.
Hormones: Hormones act as chemical messengers in the body.
1.13 A gland located in the neck that secretes thyroxin hormone.
Thyroid Gland: This gland regulates metabolism and is responsible for secreting thyroxine.
1.14 A hormone that controls the metabolic rate in the body.
Thyroxine (T4): Thyroxine plays a major role in regulating metabolism.
1.15 A hormone that increases the blood glucose level in the body.
Glucagon: This hormone raises blood glucose levels by stimulating the liver to convert stored glycogen into glucose.
1.16 A hormone that lowers the blood glucose level in the body.
Insulin: Insulin helps decrease blood glucose levels by facilitating the uptake of glucose into cells.
1.17 Promotes the secretions of hormones produced by thyroid glands.
Thyroid-Stimulating Hormone (TSH): TSH stimulates the thyroid gland to produce hormones.
1.18 A mechanism that detects imbalances and restores balance in the internal environment.
Feedback Mechanism: This includes processes like negative feedback which helps maintain homeostasis.
1.19 A hormone responsible for growth and development in the body.
Growth Hormone (GH): GH is crucial for growth, cell repair, and metabolism.
1.20 The blood vessel in the neck that contains receptors which are sensitive to carbon dioxide levels in the blood.
Carotid Artery: The carotid arteries contain chemoreceptors that detect changes in the blood.
1.21 A hormone that stimulates the production of milk in humans.
Prolactin: Again, this hormone is crucial for milk production.
