the lower respiratory tract The lower respiratory tract includes: Trachea: Windpipe that conducts air to the bronchi. Bronchi and bronchioles: Distribute air throughout the lungs. Alveoli: Tiny air sacs
ry Gland: Responds to GnRH by secreting LH (luteinizing hormone) and FSH (follicle-stimulating hormone). Testes: LH stimulates Leydig cells to produce testosterone; FSH stimulates Sertoli cells to support spermatogenesis. Ejaculation: A reflex process involving the emission of semen from accessory g
