Vertically divides the body through the midline into two equal portions or halves.
Any plane parallel to the midsagittal or median plane vertically diving the body into unequal right and left portions.
Frontal (Coronal) Plane
One that divides the anterior and posterior portions of the body at right angles to the sagittal plane.
Contains organs of the nervous system that coordinate the body's functions. Cranial cavity and the Spinal cavity.
Contains organs that are involved in maintaining homeostasis. Thoracic cavity and Abdominopelvic cavity.
Surrounded by the rib cage and contains the heart in a pericardial cavity, and the two lungs the pleural cavities.
Found between the two pleural cavities and contains the heart, thymus gland, lymph and blood vessels, trachea, esophagus, and nerves.
Second subdivision of the ventral cavity that contains the kidneys, stomach, liver and gallbladder, small and large intestines, spleen, pancreas, and the ovaries and uterus.
Aqueous colloidal solution of various proteins, lipids, carbohydrates, and inorganic salts that are organized into structures referred to as organelles.
Covers surfaces and protects both the outer suface like the skin and inner surfaces of organs like the intestine, forms glands, and lines cavities of the body.
Characterized by elongated cells that generate movement by shortening or contracting in a forcibile manner. There are three types of muscle tissue.
Smooth muscle tissue
Involuntary muscle is found in the intestines where it pushes food along the digestive tract. Also found in arteries and veins.
Nervous muscle tissue
composed of nerve cells forming a coordinating system of fibers connecting the numberous sensory and motor structures of the body.
Made up of two layers epidermis and dermis. It includes the skin, hair, nails, sebaceious glands, and sweat glands.
Integumentary system function
Insulation of the body, protection of the body from environmental hazards, and regulation of body temperature and water.
Skeletal system function
Protectes the soft and vital parts of the body and provides support for body tissues. Its bones act as levers for movement.
Consists of the brain, spinal cord, cranial nerves, peripheral nerves, and the sensory and motor structures of the body.
Consists of the endocrine glads (ductless glands), the master gland, or pituitary, controls the other glands.
Cardiovascular system function
Pump, distribute blood which carries oxygen, nutrients and wastes to and from the cells.
Lymphatic system function
drain tissue spaces of excess interstitial fluids and absorb fats from the intestine and carry them to the blood. Protects the body from disease.
Alimentary canal(mouth, esophagus, stomach, small and large intestines, rectum, and anus) with assoc. glands(salivary, liver, and pancreas.)
Urinary system function
Chemical regulation of the blood, the formation and elimination of urine, and the maintenance of homeostasis.
Consists of the ovaries uterine tubes, uterus, and vagina in females. Testes, vas deferens, seminal vesicles, prostate gland, penis, and urethra in males.
Reproductive system function
Maintenance of sexual characteristics and the perpetuation of our species.
Blood sugar levels, body temperature, heart rate, and the fluid environment of the celss.
Substance whose atoms all contain the same number of protons and neutrons which makes them electically neutral.
Formed when one atom gains electrons while the other atom loses electrons from its outermost level or orbit.
special molecules will gain electrons only to lose them to another in a very short time.
concentration outside the red blood cell equals the concentration inside the red blood cell.
water molecules are in a higher concentration outside the red blood cell, water will move into the blood cell, causing it to swell and rupture.
step after glycolysis in which pyruvic acid gets broken down in to carbon dioxide gas and water.
