Carbon dioxide is removed through the respiratory system, but there are other wastes which result when body cells burn food. Many of these wastes are in the circulating blood. Some of them are removed in the blood filtration and removal plant, which is the urinary system.

The nerves connect the body, brain, and spinal cord. A complete nerve cell consists of a cell body with thread-like fibers. The whole thing is called a neuron. Each one can be rather long, and transmits impulses in only one direction. Axons, on one end, conduct impulses away from the cell body. Dendrites, on the other end, conduct impulses to the cell.

The central nervous system includes the brain and spinal cord (which are also used by the autonomic nervous system). The brain and spinal cord are the switchboard, and the nerves are the wires that carry incoming and outgoing messages.

The seven top vertebra (in your neck) are the cervicals. The next 12 in your upper back are the thoracics. The next five, below that, are the lumbers in your lower back. Then come five sacral vertebra and, lastly, four coccygeal in your, so-called, "tail bone." Without that section, you could not sit properly.

There are 206 bones in the human body. Six of them are the ossicles in the ear. Infants have about 350 bones; but many of these eventually connect, forming the 206 bones in the adult. The bones provide a solid framework, supporting and shaping the body. They protect delicate or soft parts and anchor the muscles.

There are eight main types of endocrine glands: pineal, pituitary, parathyroids, thyroid, thymus, adrenals, islets of Langerhans, gonads (testes and ovaries). Located in different parts of the body, they pour their secretions directly into the bloodstream; so they are called ductless glands.

Endocrines - This is another amazing part of your body. Without your glandular secretions, you could not survive; yet, as with most of the rest of the human body, they are a bewildering complexity which could not be originated by chance.

Asexual reproduction is done by mitosis, as in protozoa. Human beings reproduce by sexual methods. Each female and male possesses sex glands (gonads) which produce sex cells (gametes). When the male gamete is brought into contact with the female gamete, they unite and form a new single-celled individual (a zygote).

Fertilization - An ovum leaves the ovary about halfway between menstrual cycles; it enters the fallopian tube and travels down toward the uterus. During intercourse, millions of sperm cells (200 million to 400 million) are discharged by ejaculation into the vagina.

Without muscles, you could not move an inch. Muscles are connected to bones by tendons, which enable muscles to move the bones. Muscle cells are tiny elastic threads of protein, wrapped together in bundles; several bundles make a muscle.
