Document Summary

The human heart is comprised of 4 chambers. The brachial artery gives rise to the ulnar and radial arteries. The brain is composed of two hemispheres. Mitochondria cellular organelles more numerous in active cells. Cellular energy requires the body"s production of atp. Skeletal muscles contract via a process called the sliding filament theory. Glucose (a form of simple carbohydrate) is the necessary fuel for the brain. Heart cells are capable of contracting on their own due to a property called autorhythmicity. The long-term acid-base balance of the body is controlled by the kidneys: a patient arrives in the doctor"s office complaining of pain in the chest. In some cases, the procedure would require auscultation, using a stethoscope placed over the chest and back in order to magnify the internal sounds of respiration. 3: additional insight can be gained regarding deviation from normalcy of elasticity and compliance through percussion, or tapping on the structures of the body.
