Study Notes
Cardiovascular System
- Blood Circulation (10 Key Points): Memorize 10 key facts about blood circulation.
- Heart Anatomy: Label a heart diagram (use an anatomy book).
- Semilunar Valves: Located between the aorta, pulmonary trunk, and ventricles. Allow blood to flow in one direction.
- Atrioventricular Valves: Formed from flaps that control blood flow direction. Tricuspid and mitral (bicuspid) valves are examples.
- Pulmonary Circulation: Blood moves between the heart and lungs.
- Systemic Circulation: Blood moves between the heart and the rest of the body.
- Coronary Circulation: Blood flow to the heart muscle.
- Hepatic Portal System: Transport blood from the digestive tract to the liver.
- Hemostasis: Process that stops bleeding
- Hemophilia: Blood disorder causing excessive bleeding.
- Synctium: Anatomical arrangement for heart fiber functionality
- Gap Junctions: Cell-to-cell ion passage for heart communication.
- Desmosomes: Cell adhesion, preventing separation during contraction.
- Coagulation: Blood clotting
- Hematopoiesis: Process of blood development.
- Erythropoiesis: Production of white blood cells (part of hematopoiesis).
Fetal Circulation
- Fetal Circulation Diagram: Study the diagram provided.
- Right Ventricle: Sends blood toward the lungs.
- Pulmonary trunk: Carries blood from the right ventricle to the lungs
- Foramen Ovale: Connects the right to the left atrium, bypassing the lungs
- Ductus venosus: Connects the umbilical vein to the inferior vena cava to bypass the liver
- Ductus arteriosus: Connects the pulmonary artery (right side) to the aorta (left side) to bypass the lungs
- Umbilical vein: Carries oxygenated blood from the placenta to the fetus
- Umbilical arteries: Carry deoxygenated blood from the fetus to the placenta.
- Placenta: Exchange of gases and nutrients between mother and fetus.
Blood Functions
- Blood Functions (3): Transportation, regulation, protection.
- White Blood Cell Types (5): Neutrophils, basophils, eosinophils, monocytes, lymphocytes.
Heart Structure
- Heart Layers (3): Epicardium, myocardium, endocardium.
Blood Pressure & Filtration
- Blood Hydrostatic Pressure: Promotes filtration
- Interstital fluid osmotic pressure: Promotes filtration
Blood Vessels
- Venules: Small vessels merging from capillaries.
- Veins: Vessels formed from the union of venules.
Hemostasis Steps
- Hemostasis Steps (3): Vascular spasm, platelet plug formation, blood clotting.
Heart Contractions
- Depolarization: Contraction phase
- Repolarization: Relaxation phase
- P wave: Depolarization of atria
- QRS complex: Depolarization of ventricles
- T wave: Repolarization of ventricles.
Specialized Heart Cells
- Pacemaker Cells: SA and AV nodes, exhibit slow responses, control heart rhythm.
- Nonpacemaker Cells: Contractile cells, faster response, found elsewhere in the heart.
- Intrinsic Conduction System: Initiates heartbeats starting from SA node then through the myocardium via gap junctions to the AV node and Bundle of HIS
Other
- Arteriosclerosis: Narrowing of arteries
- Atherosclerosis: Stiffening of arteries
