Study Notes
Immune System
- Thymus is a dual-function organ that serves as part of the immune system and an endocrine gland.
- Located above the anterior aspect of the heart, the thymus transforms lymphocytes into T-cells.
- T-cells play a crucial role in fighting infections and diseases.
- Thymosin, a hormone secreted by the thymus, increases the activity of T-lymphocytes.
Heart
- The heart is a crucial pump for the cardiovascular system.
- It also functions as a secondary endocrine gland, producing several hormones.
- One of these hormones is atrial natriuretic peptide (ANP), a powerful vasodilator that helps lower blood pressure.
Adrenal Glands
- Triangular-shaped glands situated on top of the kidneys.
- Regulate stress response by synthesizing hormones, including cortisol and adrenaline.
- Each adrenal gland has two distinct parts: the outer adrenal cortex and the inner adrenal medulla, which function as separate glands.
