Outline of human anatomy and Physiology unit 9 Human anatomy is the study of the shape and form of the human body. The human body has four limbs two arms and two legsa head and a neck which connect to the torso. The body's shape is determined by a strong skeleton made of bone and cartilagesurrounded by fat, muscle, connective tissue, organs, and other structures.

The spine at the back of the skeleton contains the flexible vertebral column which surrounds the spinal cordwhich is a collection of nerve fibres connecting the brain to the rest of the body. Nerves connect the spinal cord and brain to the rest of the body.

All major bones, muscles, and nerves in the body are named, with the exception of anatomical variations such as sesamoid bones and accessory muscles.

Blood vessels carry blood throughout the body, which moves because of the beating of the heart. Venules and veins collect blood low in oxygen from tissues throughout the body. These collect in progressively larger veins until they reach the body's two largest veins, the superior and inferior vena cavawhich drain blood into the right side of the heart.

From here, the blood is pumped into the lungs where it receives oxygen and drains back into the left side of the heart. From here, it is pumped into the body's largest arterythe aortaand then progressively smaller arteries and arterioles until it reaches tissue.

Here blood passes from small arteries into capillariesthen small veins and the process begins again. Blood carries oxygenwaste products, and hormones from one place in the body to another. Blood is filtered at the kidneys and liver.

The body consists of a number of different cavities, separated areas which house different organ systems. The brain and central nervous system reside in an area protected from the rest of the body by the blood brain barrier.

The lungs sit in the pleural cavity. The intestinesliverand spleen sit in the abdominal cavity Height, weight, shape and other body proportions vary individually and with age and sex. Body shape is influenced by the distribution of muscle and fat tissue. Outline of physiology and Physiology Human physiology is the study of how the human body functions.

This includes the mechanical, physical, bioelectricaland biochemical functions of humans in good health, from organs to the cells of which they are composed. The human body consists of many interacting systems of organs. These interact to maintain homeostasiskeeping the body in a stable state with safe levels of substances such as sugar and oxygen in the blood.

Some combined systems are referred to by joint names.
