Chapter 11- muscular system lever structure treat joint like effort, load and fulcrum - types: 3rd class- effort is between load and fulcrum (ex/ in biceps the load is hand, fulcrum is elbow and effort is biceps brachii muscle) 2nd class- load inbetween fulcrum and muscle (ex/ tibiotaylor joint and soleus muscle in calf) 12. 3 components of blood plasma (55%)- proteins, water and other solutes formed elements (45%) include: Rbc (erythrocytes)- hematocrit is percent of blood occupied by red blood cells. Wbc (leukocytes)- include lymphocytes platelets (thrombocytes)- cause blood clotting. 12. 5 red blood cells each rbc contains hemoglobin which carries oxygen and carbon dioxide (hemoglobin makes the blood red) disc shape increases surface area of rbc each molecule of haemoglobin can bind 4 oxygens. Rbc can ex and bend to t in the thinnest capillaries produced in red bone marrow. Muscle digastric stylohyoid mylohyoid styloid process hyoid (posteriorly) inner surface of mandible geniohyoid inner surface of mandible.
