Thick-walled, muscular, flexible tubes that carry oxygenated blood away from the heart to the arterioles.
Thin-walled, upper chamber of the heart through which blood is pumped to the ventricles. There is a right and a left.
Autonomic Nervous System (ANS)
Nervous system that controls the involuntary muscles; it regulates the action of the smooth muscles, glands, blood vessels, heart, and breathing.
Nurtritive fluid circulating through the circulatory system and is considered connective tissue. There are 8-10 pints.
Controls the steady circulation of the blood through the body by means of the heart and blood vessels. Also known as cardiovascular system or vascular system.
Commom Carotid Arteries
Main source of blood supply to the head, face, and neck. Located on either side of the neck.
Located in the uppermost part of the midbrain and has two main parts, called Thalamus and Hypothalamus
Eleventh Cranial Nerve
Type of motor nerve that controls the motion of the neck and shoulder muscles. Also known as the accessory nerve.
Release secretions called hormones directly into the bloodstream, which in turn influence the welfare of the entire body. Also known as ductless glands.
Group of specialized glands that affect the growth, development, sexual activities, and health of the entire body.
Produce a substance that travels through small. tube-like ducts. Sweat and oil glands of the skin belong to this group. Also known as duct glands.
Supplies blood to the lower region of the face, mouth and nose. Also know as external maxillary artery.
Facial Nerve (VII)
Branches of this nerve innervate the taste buds, the skin of the external ear, and the salivary and lacrimal glands. Also controls facial expressions.
Fifth Cranial Nerve
The largest of the cranial nerves. Chief sensory nerve of the face, and it serves as the motor nerve of the muscles that control chewing. Consists of three branches.
Often referred to as the bodys pump. Muscular, cone-shaped organ that keeps the blood moving within the circulatory system.
Clear, yellowish fluid that circulates the lymph spaces of the body; carries waste and impurities away from the cells.
or bicuspid valve; a flap like structure that prevents the back flow of blood as it is pumped from the left atrium to the left ventricle
Whitish cords, made up of bundles of nerve fibers held together by connective tissue, through which impluses are transmitted.
Exceptionally well-organized system that is responsible for coordinating all the many activities that are performed by the body.
Affects the skin of the forehead, upper eyelids, and interior portion of the scalp, orbit, eyeball and nasal passage.
Secretes enzyme-producing cells that are responsible for digesting carbohydrates, proteins, and fats. Cells within the control insulin and glucagon production.
Most complex organ of the endocrine system. It affects almost every physiologic process of the body.
Much smaller than red blood cells. They contribute to the blood-clotting process, which stops bleeding. Also known as thrombocytes.
Posterior Auricular Artery
Supplies the scalp, the area behind and about the ear, and the skin behind the ear.
Automatic nerve reaction to a stimulus that involves the movement of an impluse from a sensory receptor along the afferent neuron to the spinal cord and a responsive impluse back along an efferent neuron to a muscle, causing a reaction.
Spinal Accessory Nerve (XI)
This nerve brings about movement in the head and shoulders. Also is involved in the production of voice sounds.
Carries the oxygenated blood from the heart throughout the body and ack to the heart again.
Trigeminal Nerve (V)
Contains sensory fibers that relay signals from the head, face, and teeth. (Chewing muscles). The branches are known as opthalmic, mazillary, and mandibular.
Consists of the heart, arteries, veins, and capillaries for the distribution of the blood throughout the body.
