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.

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.
