The human body consists of biological systems, that consist of organs, that consist of tissues, that consist of cells and connective tissue. The history of anatomy has been characterized, over a long period of time, by a continually developing understanding of the functions of organs and structures in the body.
The skeletal muscles of the body typically come in seven different general shapes. This figure shows the human body with the major muscle groups labeled. The gross anatomy of a muscle is the most important indicator of its role in the body. One particularly important aspect of gross anatomy of muscles is pennation or lack thereof. In most ...
During starvation, the body uses the fat in yellow marrow for energy. [7] The red marrow of some bones is an important site for blood cell production, approximately 2.6 million red blood cells per second in order to replace existing cells that have been destroyed by the liver. [4] Here all erythrocytes, platelets, and most leukocytes form in ...
