Ati teas study guide 2022
Superior : - toward the head
Inferior : - Lower on the body, farther from the
... [Show More] head Anterior (ventral) : - front side of the body
Posterior (dorsal) : - back of body
Proximal : - Nearer to the trunk of the body
Medial : - Toward the midline of the body
Lateral : - away from the midline of the body
cavities : - Internal structure of the human body
dorsal cavity : - includes the cranial and spinal cavities. cranial cavity : - contains the brain
Distal : - farther from the origin of a body part or the point of attachment of a limb to
the body trunk
spinal cavity : - contains the spinal cord
Meninges : - three protective membranes that surround the brain and spinal cord ventral cavity : - thoracic cavity, abdominal cavity, pelvic cavity
thoracic cavity : - contains heart and lungs
abdominal cavity : - digestive organs, spleen, kidneys
pelvic cavity : - Contains urinary bladder, reproductive organs, and rectum peritoneum : - membrane that lines the abdominal and pelvic cavity
heart : - A hollow, muscular organ that pumps blood throughout the body. pericardial cavity : - surrounds the heart
The heart has 3 layers, what are they? : - endocardium, myocardium, epicardium
circulatory system : - Circulates nutrients,gases,wastes,and other substances
throughout the body.
pulmonary loop : - Carries deoxygenated blood from the heart to the lungs and back
to the heart
systematic loop : - Oxygenated blood is pushed out of the heart and travels through
larger blood vessels until it reaches the capillaries,where gas exchange takes place
endocardium : - The protective outermost layer of the heart composed of connective
tissue
Myocardium : - middle layer, mostly cardiac muscle ,performs the pumping function
to the circulate blood
Endocardium : - smooth layer of cells that lines the inside of the heart that keeps the
blood from sticking to the inside of the heart
The heart has 4 chambers. what are they? : - right atrium, left atrium, right ventricle,
left ventricle
Atriums : - the two upper chambers of the heart, receive blood from the lungs and
body and pump it to the ventricles
Ventricles : - the two lower chambers of the heart, and they pump blood out to the
lungs and body so they are larger
atrioventricular valves : - valves that keep the blood from going back into the atria
from the ventricles
semilunar valves : - valves that prevent blood return to the ventricles from the
arteries
Pumping function of the heart : - Sinoartrial and atrioventricular nodes sinoatrial (SA) node : - Set pace and signals the atria to contract
blood vessels : - tubelike structures that carry blood throughout the body lumen : - Hollow part of a tubular structure such as a blood vessel or intestine Arteries : - Blood vessels that carry blood away from the heart
Aorta : - Largest artery in the body
pulmonary artery : - Carries deoxygentated blood from the heart to the lungs
brachiocephalic artery : - carries blood to the brain and head left common carotid artery : - carries blood to the brain
iliac arteries : - deliver blood to the pelvic area and lower extremities Veins : - Blood vessels that carry blood back to the heart
Venules : - thin veins that connect to the capillaries
inferior vena cava : - carries blood from lower regions of the body to right atrium Capillaries : - Smallest blood vessels
atrioventricular (AV) node : - Picks up the signal from the sinoatrial node, the signals
tells the ventricles to contract
Arterioles : - narrower arteries that branch off of main arteries and carry blood to the
capillaries
aortic arch branches : - brachiocephalic trunk, left common carotid artery, left
subclavian artery
left subclavian artery : - Third branch of the aortic arch that distributes blood to the [Show Less]
