Lab 1 Endocrine Glands and Blood smear Slides

Thyroid & Parathyroid

The thyroid gland produces hormones such as thyroxine that regulate metabolism, while the parathyroid glands regulate calcium levels in the blood through parathyroid hormone.

Pancreas

An organ that produces insulin and glucagon, which regulate blood sugar levels.

Testis

The testis is an organ that produces sperm and hormones such as testosterone, which play key roles in male reproductive functions.

Ovary

The ovary is an organ that produces eggs and hormones such as estrogen and progesterone, which are essential for female reproductive functions.

Adrenal Gland

An endocrine gland that produces hormones such as adrenaline and cortisol, which help regulate metabolism, immune response, and stress.

Eosinophil

Destroys parasites and helps control inflammation and allergic reactions

Neutrophil

Phagocytizes bacteria. Most abundant of WBCs

Platelets

Cell fragments involved in blood clotting and wound repair.

Monocytes

Largest of all WBCs. Crucial against viruses, intracellular bacterial parasites, and chronic infections.

Basophil

A type of white blood cell that releases histamine during allergic reactions and helps to protect against parasites.

Hypothalamus

Secretes releasing and inhibiting hormones to the anterior pituitary gland to regulate hormone secretion. The thyrotropin-releasing hormone (TRH), gonadotropin-releasing hormone (GnRH), growth hormone-releasing hormone (GHRH), corticotropin-releasing hormone (CRH)

Pituitary Gland

Consists of Anterior pituitary gland and Posterior pituitary gland

Pineal Gland

Produces Melatonin and is responsible for regulating sleep and wake cycle

Anterior Pituitary Gland

Releases Oxytocin and Antidiuretic Hormone (ADH)

Posterior Pituitary Gland

Produces Growth Hormone (GH), Thyroid-stimulating hormone (TSH), Adrenocorticotropic hormone (ACTH), Follicle-stimulating hormone (FSH), Luteinizing hormone(LH) and Prolactin.
