Side ASide B
Salivary Glands
Produce saliva containing amylase, chloride ions, water, and mucus
Epiglottis
Prevents food from entering airway passages
Esophagus
Transports bolus of food from oral cavity to stomach
Diaphragm
Contraction draws air into lungs
Thymus
T-cell maturation site
Thyroid
Produces hormones that regulate metabolism and heat production
Trachea
Transports air from larynx to bronchi
Larynx
Voice box
Vocal cords
Production of sound
Lungs
Gas exchange
Liver
Produces bile, detoxifying poisons, glycogen formation
Gallbladder
Produces bile which breaks down fat
Stomach
Receives food from esophagus and digestion
Duodenum
Completes chemical digestion and begins nutrient absorption
Jejuno-ileum
Nutrient absorption
Pancreas
Secretes digestive enzymes into small intestine and insulin and glucagon into the blood stream.
Spleen
Filters blood, removing red blood cells
Mesentary
Membrane supporting the coils and blood vessels.
Large intestine
Reabsorbs water and ions
Cecum
Blind sac at the beginning of the large intestine; fermentation of cellulose
Rectum
Water reabsorption and fecal storage until elimination.
Right atrium
Receives blood from body and pumps to right ventricle.
Left atrium
Receives oxygenated blood from lungs and pumps to left ventricle
Right ventricle
Receives blood from right atrium and pumps to lungs to be oxygenated
Left ventricle
Receives oxygenated blood from the left atrium and pumps to the body
Coronary artery and vein
Supplies blood to heart tissue
Superior vena cava
Carries oxygen-poor blood from the head, neck, pectoral appendages and cranial part of the...
Inferior vena cava
Carries oxygen poor blood from the caudal parts of the body to the right atrium.
Pulmonary trunk
Transports deoxygenated blood from right ventricle to lungs
Pulmonary veins
Transports oxygenated blood from the lungs to the left atria
Aorta
Transports oxygenated blood from left ventricle to the body
Tricuspid valve
Prevents backflow from the right ventricle into the right atria
Bicuspid valve
Prevents back flow of oxygen rich blood from the left ventricle into the left atria
Aortic valve
Prevents backflow of blood from the aorta to the left ventricle
Pulmonary semilunar valve
Prevents backflow of blood from pulmonary trunk (artery) into the right ventricle
Umbilical vein and artery
Circulates deoxygenated nutrient poor blood back to mother and brings oxygenated nutrient rich...
Erthrocytes
Transport oxygen to body's tissues
Leukocytes
Defend body by phagocytizing bacteria, producingantibodies for the immune system, and killing...
Platelets
Assist in blood clotting
Kidney
Excrete urea, regulates water and solute concentration
Ureter
Transports urine from kidney to the urinary bladder
Urethra
Transports urine from bladder to urogenital opening
Adrenal gland
Produces epinephrine (fight/flight hormone)
Ductus deferens
Transports sperm from epididymus to the urethra.
Testis
Produce sperm and hormones
Epididymus
Stores sperm
Bulbourethral gland
Secretes seminal fluid at ejaculation
Ovaries
Produce eggs and hormones
Oviduct/Fallopian tubes
Captures eggs from ovary and transports to uterus
Uterus
Fetal development
Vagina
Receives penis during copulation
Urogenital canal/Vaginal vestibule
In pigs, not humans, common passageway of the vagina and urethra to the body surface
Penis
Transport urine during urination and sperm during copulation
