Anatomy
What does the right ventricle do?
Pumps deoxygenated blood to the lungs
What does the left atrium do?
Pumps oxygenated blood to the left ventricle
What does the left ventricle do?
Pumps oxygenated blood to the entire body, thickest chamber of the heart
What does the aorta do?
Largest artery, carries oxygenated blood away from the left ventricle to the body
What does the pulmonary artery do?
Carries deoxygenated blood from the right ventricle to the lungs
What do the pulmonary veins do?
Carry oxygenated blood from the lungs to the left atrium
What does the superior vena cava do?
Delivers deoxygenated blood from upper body to right atrium
What does the inferior vena cava do?
Delivers deoxygenated blood from lower body to the right atrium
What does the tricuspid valve do?
Opens to pass deoxygenated blood from right atrium to right ventricle
What does the bicuspid valve do?
Opens to pass oxygenated blood from left atrium to left ventricle
What does the pulmonary valve do?
Opens to pass blood from right ventricle to pulmonary arteries
What does the aortic valve do?
Opens to pass blood from left ventricle to aorta
Superficial oxygen layer of the kidney, lighter in color
What is the renal medulla?
Deeper portion of the kidneys, darker in color, broken into segments called renal pyramids ( looks like a seashell)
What is the renal pelvis?
Funnel- shaped, collects urine from calyces
What is the ureter?
Narrow tubes, carry urine from renal pelvis to urinary bladder
What is the renal artery?
Carry unfiltered blood into kidneys to be filtered, deliver approx. 1 liter of blood per minute
What does the renal vein do?
Carry filtered blood away from the kidneys and to the inferior vena cava
What is the nasal cavity?
Hollow area behind the nose, rich in mucus membranes, warms air as it travels to the lungs
What is the pharynx?
The throat, splits into esophagus and larynx
What is the larynx?
Voice box, passes air to the trachea, houses vocal cords
What is the trachea?
The windpipe, passes from larynx to lungs, supported by rings of cartilage
What is the bronchi?
Two branches (right and left) at the bottom of the trachea, each leads to a lung, branch further in lungs
What is the diaphragm?
Dome-shaped skeletal muscle "wall" beneath the lungs, contracts to cause inspiration, relaxes to cause expiration
What is the alveoli?
Thin walled air sacs in lungs, covered in capillaries, the specific site of external respiration
