Nervous System.● The nervous system consists of the brain, spinal cord, sensory

organs, and all of the nerves that connect the organs with the rest of the body. They’re responsible for the control of the body and communication of the parts.

● The use of alcohol can affect the nervous system in particular the central nervous system.

● Organs in this system is the brain which has the ability to detect, recognise, remember and direct. Then followed by the Spinal Cord that is a cord of nerve tissue that extends from the medulla oblongata of the brain along almost the full extremity of the vertebral column.Then comes the nerve cell or neuron which consists of a cell body with one or more elongated projections extending from it. Finally comes the sensory organs which are the eyes, ears, Olfactory organ for smell and taste buds for taste.

Respiratory System● The respiratory system what does is it includes air passages,

pulmonary vessels, the lungs, and breathing muscles, provides oxygenated blood to the body tissues and removes waste gases.

● the airway, the lungs, and the muscles of respiration are the the 3 major parts. The airway which includes the nose, mouth, pharynx, larynx, trachea, bronchi, and bronchioles, carries air between the lungs and the body's exterior

● The right lung is slightly larger than the left. Hairs in the nose help to clean the air we breathe as well as warming it.

● First the body breathes in the air which is sucked through the nose or mouth and down through the trachea. The trachea is a pipe shaped by rings of cartilage. It divides into two tubes called bronchi. These carry air into each lung. Inside the lung, the tubes divide into smaller and smaller tubes called bronchiolies. At the end of each of these tubes are small air balloons called alveoli.

Muscular System● This system is responsible for the movement of the

human body. Attached to the bones of the skeletal system are about 700 muscles.

● Visceral or smooth muscle is found inside organs such as the stomach and intestines, as well as in blood vessels.They are three types of muscle tissue which are the smooth muscle, cardiac muscle, and the skeletal muscle.consisting of muscle fibers, connective tissue, nerve tissue and blood tissue.
