Biology today is subdivided into numerous branches based on the molecule, the cell, the organism and the population.Living and Non-Living There are seven characteristics that can be observed, more or less, in all living organisms. In order to maintain themselves and prevent disintegration, organisms have an inbuilt self-regulating system to ensure that there is no net energy loss. This control is referred to as homeostasis and operates at all levels of biological organisation, from the molecular level to the community level.The HeartThe HeartIts average weight is about 340 grams in men and 255 grams in women. The left half and the right half of the heart is divided by a wall called septum. Each half, in turn, is divided into an upper chamber called the auricle and a lower chamber called the ventricle. The auricle receives blood from the veins and the ventricle pumps blood into the arteries.Heartbeats In a normal, healthy adult, the contraction and relaxation mechanism of the ventricles results in a heartbeat of about 70-72/min in males and 78-82/min in females.
