AP Biology Exam Review Body Systems
Controllingbreathing • Medulla oblongata • Autonomic nervous system
Blood CO2 transport • Carbonic acid (changes in pH) • Hemoglobin = heme group, able to bind oxygen
Control • Detecting increase in blood pressure triggers excretory actions
Endocrinesystems • Hypothalamus controls the pituitary gland • Pituitary gland controls the majority of hormones.
Maleanatomy • Testes – produces sperm • Testes held in scrotum
Menstruation • FSH • LH • Estrogen • Progesterone
Human embyonicdevelopment • Blastocyst (blastula – hollow ball) • Gastrulation (gastrula – cells dive into center)
Action potential • Depolarize – inside of axon more positive • Hyperpolarize – inside of axon less negative • Refractory period – “recovery” period to reestablish resting potential
