Heart: Blood flow: Right Atrium-----Tricuspid valve----Right Ventricle-----Pulmonary valve----Pulmonary trunk---- Rt. & Lt Pulmonary Arteries------Rt. & Lt Lungs----Rt. Lt Pulmonary veins---Lt. Atrium----Mitral Valve--- Lt. Ventricle---Aortic Valve---Aorta---Systemic Circulation Cardiac Output: Amount of blood ejected by the heart in one minute. Heart rate: Bradycardia, <60 bpm, Tachycardia, >100bpm Epinephrine: increases HR Pulmonary arteries, 2, carry deoxygenated blood to lungs Pu...

Connective Tissue elements (CT) 1. Ligament : CT that binds bone to bone 2. Tendon: CT that binds muscle to bone 3. Aponeurosis: CT that binds muscle to muscle Bones: Know Illustrations. eg. Humerus, radius, ulna, femur, tibia sternum,mandible Bone Cells 1. Osteoblasts, osteocytes, osteoclasts. 1. Osteoblast: makes new bone tissue 2. Osteocyte: maintains healthiness of bone 3. Osteoclast: breakdown of bone Covering of bone: Periosteum

Define anatomy/physiology/pathophysiology/homeostasis 1. Anatomy= the study of body structure 2. Physiology= the function of body 3. Pathophysiology=Improper function “what went wrong” 4. Homeostasis= Stable, staying the same Directional Terminology 1. Anterior (Ventral)= “Front” 2. Posterior (Dorsal)= “Back” 3. Inferior= bottom 4. Superior= top 5. Lateral= away from midline (side) 6. Medial =center or in the middle 7. Proximal =close to attachment 8. Distal= away fr...
