• Systemic circulation moves blood through all parts of the body, except the lungs.
• Atria are the two thin walled upper chambers of the heart.
• The largest veins are the venae cavae.
• Numerology studies the structure, functions, disorders, diseases and the respiratory system.
• The femur is the largest and longest bone in the leg and body.

• Flexors are muscles that decrease the angle between a muscle and a joint.
• Deltoid is the muscle allows raising your arms up to the side.
• Biceps brachii bends the arm at the elbow.
• Hypertrophy is the enlargement of an organ or tissue from the increase in size of its cells.
• Homeostasis maintains the condition of the internal environment in the body.
• Sensory receptors are nerve endings in the dermis that communicate.
