| Term | Definition |
|---|---|
| Endocrine levels | Stress, infection, blood's fluid, and electrolyte imbalance impact these levels |
| Pituitary hormones | Anterior: ACTH, TSH, LH, FSH, PRL, GH, AND MSH |
| Peptide hormones | Posterior pituitary gland: Oxytocin |
| How is thyroid generated | Takes iodine and convers to thyroid hormone. Amino acid and Tyrosine combined make T3 and T4 which control metabolism. |
| Parathyroid gland | 4 of them located behind the thyroid and there is no relation to the thyroid, Controls calcium in our bodies |
| Cushing's disease | Pituitary tumor secreting ATCH, due to cortisol excess in the blood |
| Basic components of blood | Plasma, Red blood cells, White blood cells, and Platelets |
| Different types of WBC | Granulocytes and A Granulocytes. Neutrophils, Eosinophils, Basophils, Lymphocytes, and Monocytes. |
| Clotting factors | Blood changes from liquid to gel, hemostasis occurs, aggregation of platelets and maturation of fibrin. |
| Cascade factors in the blood | Forms clotting, activates protein platelets, secondary hemostasis taking two pathways intrinsic and extrinsic. |
| Pathways | Intrinsic: initiated where Intrinsic and Extrinsic coagulation cascade converges. Extrinsic: initiated at site of injury. |
| Heart chamber's | 4 chambers 2 right receive poor oxygen blood and 2 left pump oxygen rich blood |
| How blood flows | R atrium receives poor blood, pumps it to R ventricle through Tricuspid v, R ventricle pumps poor blood to Lungs, L atrium receives oxygen blood pumps to Left ventricle via Mitral v. L ventricle pumps oxygen rich blood to the body via Aortic valve. |
| Protein elements | Albumin, RBC, WBC, Platelets, and Plasma. |
| Formed elements | erythrocytes (red blood cells, RBCs), leukocytes (white blood cells), and thrombocytes (platelets). By vol., the RBC constitute about 45% of whole blood, the plasma about 54.3%, and WBC about 0.7%. |
| General cells, WBC and RBC | WBC: Complete cell, Neutrophils and Lymphocytes (T and B cells make antibodies) RBC: starts in the marrow in 7 days goes to bloodstream, has no nucleus, lasts only days |
| Leucopoiesis | Too much WBC |
| EPO | Erythropoietin, a hormone produced by the kidneys controls RBC reproduction used to treat anemia |
| Polycythemia | Too much hemoglobin in the blood |
| Anemia | need RBC, B12, Iron |
| Sickle cell anemia | happens in the tropics by the Equator, shaped like the moon, cannot provide proper oxygen to the rest of the body. |
| Malaria | Mosquito born disease by parasite causes flu like symptoms and if not treated coma, even death. |
| Low half life hormones | Duration hormone remains in the blood, Ex. thyroid 1 week, |
