- Classification of Bones ()
The adult human skeleton usually consists of 206 named bones. These bones can be grouped in two divisions: axial skeleton and appendicular skeleton. The 80 bones of the axial skeleton form the vertical axis of the body. They include the bones of the head, vertebral column, ribs and breastbone or sternum. The appendicular skeleton consists of 126 bones and includes the free appendages and their […]
- Physiology Of The Musculoskeletal System ()
Bones, Ligaments, Tendons, and Joints Humans are vertebrates, animals having a vertebral column or backbone. They rely on a sturdy internal frame that is centered on a prominent spine. The human skeletal system consists of bones, cartilage, ligaments and tendons and accounts for about 20 percent of the body weight. The living bones in our bodies use oxygen and give off waste products in metabolism. […]
- Another Trip Into The Circulatory System ()
Classification & Structure of Blood Vessels Blood vessels are the channels or conduits through which blood is distributed to body tissues. The vessels make up two closed systems of tubes that begin and end at the heart. One system, the pulmonary vessels, transports blood from the right ventricle to the lungs and back to the left atrium. The other system, the systemic vessels, […]

Cardiac Muscle Contracts, Conducts Electricity, And Sometimes Generates It’s Own Impulse Recall that cardiac muscle shares a few characteristics with both skeletal muscle and smooth muscle, but it has some unique properties of its own. Not the least of these exceptional properties is its ability to initiate an electrical potential at a fixed rate that […]
- The Life Cycle of Energy Produced By Cells ()
Cellular Respiration is the process used by animal cells to convert nutrients to energy (ATP), and then to release waste, such as CO2. Photosynthesis is the process that plants cells use to convert light, water, and carbon dioxide to energy, and then to release waste in the form of oxygen and glucose. All Living Things Require […]
- How Cells Work ()
The cell is the fundamental organizational unit of life. All living things are composed of cells, which then further subdivide based on the presence or absence of the nucleus, into two types: eukaryotic cells – these cells are present in all the human, animal and plants with a clear, distinct nucleus. Prokaryotic cells are some bacteria and blue-green algae […]
- What Is A Cell? ()
In biology, the smallest unit that can live on its own and that makes up all living organisms and the tissues of the body is the cell. Cells are the basic building blocks of all living things. The human body is composed of trillions of cells. They provide structure for the body, take in nutrients […]
- Anatomy and Physiology of Organs Related To Delivery ()
The uterus is where the fetus lives The uterus is a hollow muscular organ located in the female pelvis between the bladder and rectum. The ovaries produce the eggs that travel through the fallopian tubes. Once the egg has left the ovary it can be fertilized and implant itself in the lining of the uterus. […]
- The Endocrine System ()
Endocrine systems, also referred to as hormone systems, are found in all mammals, birds, fish, and many other types of living organisms. They are made up of: Glands located throughout the body; Hormones that are made by the glands and released into the bloodstream or the fluid surrounding cells; and Receptors in various organs and […]
- The Organs of the Abdominopelvic Cavity ()
The anatomy of the body is organized in cavities Organs of the abdominopelvic cavity The abdominopelvic cavity can be subdivided into four quadrants. The quadrants are labeled by location: the right upper, right lower, left upper, and left lower quadrants. The purpose of the abdominal divisions is to describe regional anatomy in the abdomen, and […]
