BMS 208; Final Exam Study Guide Respiratory System nasal cavity oral cavity pharynx (throat) larynx (voice box) trachea bronchi alveolar sacs alveoli Nasal cavity is made up of superior, middle, and inferior conchae and the ethmoid bone Pharynx: nasopharynx oropharynx laryngopharynx Larynx: epiglottis (lid) thyrohyoid bone laryngeal prominence thyroid cartilage (sides) cricoid cartilage (back) arytenoid cartilage (where vocal cords attach) Superior vocal cords = false Inferior vocal cords = true Trachea: Trachealis: back of trachea lined with smooth muscle Front is lined with hyaline cartilage Pseudostratified ciliated columnar epithelium with goblet cells Goblet cells produce mucous to trap pollutants Bronchial Tree: main bronchus secondary bronchus (supplies lobes) tertiary bronchus (supplies segments) bronchioles terminal bronchioles pulmonary lobule Pulmonary Lobule: Respiratory bronchioles alveolar ducts alveolar sacs alveoli Alveolar Cells: Type 1: epithelial cells Type 2: make surfactant Alveolar macrophages: ingest and remove debris Respiratory Membrane: Epithelium Basement membrane Endothelium Appearance of Lungs: Right Lung o Oblique and horizontal fissures o Superior, middle, inferior lobes Left Lung o Oblique fissure o Superior and inferior lobes Digestive System Gastrointestinal tractoral cavity pharynx esophagus stomach large/small intestine Accessory Digestive Organs: Salivary glands o Parotid o Sublingual (under tongue) o Submandibular (on mandible) Liver Gallbladder Pancreas Oral Cavity: Tongue Hard palate Soft palate (posterior) Uvula Epiglottis Esophagus Vestibule: space between lips Salivary amylase: enzyme in saliva that aids in digestion Esophagus: Upper esophageal sphincter Lower esophageal sphincter Lined with longitudinal and circular muscle Layers: serosa muscular submucosa mucosa Stomach: Greater curvature Lesser curvature Cardia (esophagus joins stomach) Fundus Pyloris Pyloric sphincter Rugae (gastric folds) o Give rise to gastric pits o Mucous cells (inside pit) o Parietal cell (make HCl) o Chief cell (make pepsinogen) Small Intestine: Duodenum Jejunum Ileum Plica: folds in the mucosa layer of the small intestine Submucosa of small intestine is dense, irregular connective tissue Intestinal villus: projections in the plica that have their own projections called micro villi Large Intestine: Cecum (small intestine attaches) Ileocecal valve Ascending colon Transverse colon Descending colon Sigmoid colon Rectum Anal cavity Liver: Synthesizes bile Right and left lobes Gallbladder is located under right lobe Caudate lobe (posterior) Quadrate lobe (anterior) Hepatocytes: liver cells Pancreas: Head (next to duodenum) Body Tail Produces enzymes that take action in the duodenum Acinar cells that produce: o Pancreatic amylase (carbohydrates) o Pancreatic lipase (fats) o Proteolytic (proteins) Endocrine Cell Type Hormone Target Action Alpha Cells Glucagon Liver Increase blood glucose levels Beta Cells Insulin Most cells Decrease blood glucose levels Left and right hepatic ducts come together to form the common hepatic duct Unneeded bile from the pancreas is sent through the cystic duct to the gallbladder Urinary System Kidneys: Remove waste Turn ammonia into urea Balance pH Secretes renin: raises blood pressure Medulla: middle of kidney Cortex: rim of kidney Renal lobe Papilla: projections at end of pyramid Minor calyx: under one papilla Major calyx: more than one Renal pelvis Ureter Hilus of kidney: contains renal pelvis, renal arteries and renal veins Flow of Arteriole Blood: renal artery segmental artery interlobar artery cortex archuate artery interlobular artery nephron afferent arteriole glomerulus efferent arteriole Venous Blood Flow: interlobular vein archuate interlobar segemental reanl vein Nephron: main unit of the kidney o Cortico nephron: in cortex o Medullary nephron: in cortex and medulla Renal corpuscle: bowman’s capsule and the glomerulus Peritubular capillaries: reabsorb nutrients, located around the distal and proximal tubules Vasa Recta capillaries: reabsorb nutrients, located around the loop of henle Antidiuretic hormone: stimulates retention of water by kidney tubules Bowman’s Capsule: visceral layer (podocytes), parietal layer Hormones of the Adrenal Gland: Aldosterone: targets the kidney, stimulates retention of sodium and excretion of potassium Cortisol: stimulates glucose formation Androgens: stimulates masculinization Bladder: Left and right ureters lead to the bladder Covered in rugae except for the Trigone area which leads to the urethra 2 sphincters: internal and external (voluntary) Reproductive System Gametes: reproductive cells o Males: sperm o Females: eggs (ova) Gonads: Organs that produce gametes o Males: testes o Females: Ovaries Follicle Stimulating Hormone: o Males: supports sperm o Females: makes follicles grow faster Leutanizing Hormone: o Males: stimulates production of testosterone o Females: stimulates ovulation Male: sperm produced in testes matures in epididymis ductus deferens seminal vesicle (produces secretion with fructose) ejaculatory duct prostate gland (basic pH) bulbourethral gland urethra (prostatic, membranous, penile) Corpus cavernosum: area of vessels in the penis that fill with blood during erection Corpus spongiosum: ensures the urethra stays open Interstitial cells: produce testosterone Female: Uterus 2 ovaries Fundus Cervix Vagina Uterine tube Labia majora Labia minora (internal folds) Urethra (superior to the vaginal opening) Begins with primordial follicle, the none dominant follicle will leave the ovary after maturation Corpus luteum: leftover matured follicles, produce progesterone which thickens the lining of the uterus Follicular cells: produce estrogen, develops female characteristics Fertilization (zygote) cleavage (division) gastrulation (blastocyst) organogenesis Female Breast: Alveoli: produces milk due to a hormone secreted from the pituitary gland called prolactin Lactiferous ducts: milk travels through Areolar glands: outside on the areola, produce a waxy substance to prevent chafing
