Fetal circulation
Ductus venosus shunts around the liver, foramen ovale moves it from R atrium to L atrium, ductus arteriosus moves it from pulmonary artery to aorta
Hepato
Liver
Cortisol
Increases blood glucose levels, decreases glycolysis
Diabetic ketoacidosis
Muscle tissue is degraded to produce alanine to produce pyruvate which creates hyperglycemia
Bowman's filtration rate
Increased hydrostatic pressure decreases filtration rate
Insulin
Increases glycolysis and glycogen synthesis (more glucose in cells and need something to do with it)
Thyroid hormone
Increases metabolism, stimulates protein synthesis everywhere
Heart valves
Tricuspid (right), mitral/bicuspid (left), pulmonic, aortic
Erythropoietin
Stimulates bone marrow to produce more RBCs to increase O2 carrying capacity, released by kidneys
Oxygen dissociation curve
Right - decrease in affinity of hemogloin for O2 (ex. BPG, CO2, H+, heat); left - increase (fetal hemoglobin)
Lungs
Left lung is smaller because of the heart
Ileum
Longest part of the small intestine
Larynx
Voice box
HIV
Destroys T-cells
