Then the endocrine system has the following: gonads (ovaries and testes), pineal gland, hypothalamus, pituitary gland, thymus, thyroid gland, parathyroid glands, adrenal glands, pancreas, and there are still more cells in charge of hormone production in other organs.
The cardiovascular gland is constituted of the blood, heart, and blood vessels.
Lymphatic fluid, vessels, spleen, thymus, lymph nodes, tonsils, and cells that execute immune responses make up the lymphatic system.
The respiratory system is made up of the lungs, pharynx and larynx, trachea, and bronchial tubes.
