physiology weeks 7-13
| What is the primary role of blood and what key physiological mechanisms support it? (Ch. 18) | Blood transports nutrients, gases, hormones, and wastes; its roles rely on formed elements (like RBCs, WBCs, platelets), hemostasis, and plasma proteins for clotting and immunity. |
| How does the cardiac cycle function, and what drives the heart’s rhythm? (Ch. 19) | The cycle alternates between systole (contraction) and diastole (relaxation), coordinated by electrical conduction (SA & AV nodes), generating cardiac output |
| What factors regulate blood flow and pressure in the vascular system? (Ch. 20) | Regulated by vessel diameter (resistance), pressure gradients, sympathetic tone, and localized vasodilation/constriction; capillary exchange occurs via diffusion and filtration. |
| How do innate and adaptive immune responses differ in mechanism and function? | Innate immunity offers immediate, nonspecific defense (barriers, phagocytes), while adaptive immunity (B and T lymphocytes) provides delayed, specific, and memory-based responses. |
| Summarize the stages of ventilation and how gas exchange occurs. (Ch. 22) | Ventilation consists of inhalation and exhalation; gas exchange occurs via diffusion in alveoli (O₂ into blood, CO₂ out), then transported bound to hemoglobin or dissolved. |
| How is digestion regulated and nutrients absorbed in the digestive system? | Regulated by neural (e.g., enteric system) and hormonal controls (gastrin, secretin); absorption occurs primarily via small intestine villi and microvilli for carbs, proteins, and lipids. |
| What are the metabolic pathways for carbohydrate, lipid, and protein metabolism? | Carbs: glycolysis → TCA cycle; lipids: β-oxidation to acetyl-CoA; proteins: deamination feeding into gluconeogenesis or ATP production.Describe the glomerular filtration, tubular reabsorption, and secretion processes. |
| Describe the glomerular filtration, tubular reabsorption, and secretion processes. | Filtration in glomerulus; reabsorption of water/nutrients in tubules; secretion of wastes and H⁺/K⁺ for homeostasis; regulated by hormones (ADH, aldosterone). |
| How does the body regulate fluid, electrolyte, and acid-base balance? (Ch. 26) | Maintains osmotic and electrolyte homeostasis via thirst, ADH, RAAS; acid-base balance via buffers, respiration (CO₂ exhalation), and renal H⁺/HCO₃⁻ regulation. |
| Explain the integration of respiratory, circulatory, and urinary systems in maintaining pH balance. | CO₂ produced by cells (respiration) enters blood; kidneys excrete H⁺ and reabsorb HCO₃⁻; lungs adjust ventilation to regulate CO₂, collaborating to maintain pH homeostasis. |
