| Question | Answer |
|---|---|
| CNS vs PNS | CNS: structural and functional center of the nervous system containing the brain and spinal cord, interpreting sensory information, and initiates outgoing response. PNS: contains nerve tissues that are in "peripheral" outer regions. |
| Sympathetic vs Parasympathetic divisions | Sympathetic: fight or flight Parasympathetic: rest and repair |
| Types of senses | Sense of: pain, temperature, touch, proprioception, smell, taste, hearing/ balance, vision |
| Major endocrine glands and locations | Hypothalamus (cranial) Pituitary (cranial) Pineal (cranial) Thyroid/ Parathyroid) (neck) Thymus (mediastinum) Adrenal (abdominal/ retroperitoneal) Pancreatic (abdominal/ pancreas) Ovaries (pelvic) Testes (scrotum) Placenta (pregnant uterus) |
| Classes of blood cells | Erythrocytes (transports O2/ CO2) Neutrophils (cellular defense) Basophils (heparin secretion) Eosinophils (cellular defense) Lymphocytes (humoral defense) Monocytes (macrophage) Platelet (blood clotting) |
| Artery/ Vein/ Capillaries | Artery: carries blood away from heart Vein: carries blood towards heart Capillaries: carries blood between arteries and veins permitting substance exchange between blood and surrounding tissue |
| Layers of heart | Epicardium: outer layer Myocardium: middle bulky layer Endocardium: interior lining |
| Fetal circulation components | 1. Two umbilical arteries 2. Placenta 3. Umbilical vein 4. Ductus Venous/ arteriosus 5. Foramen ovale |
| Starling's law of the heart | -The longer and more stretched the heart fibers in the beginning of contraction, the stronger the general contraction. -The amount of blood in the heart at the end of diastole determines amount of stretch/ preload placed on heart fibers. |
| Ejection fraction | Ratio of stroke volume to end-diastolic volume |
| Afterload | The pumping work that the heart must do to push blood into the arteries. The harder the push, the lower the stroke volume. |
