Heart
The chamber that receives oxygenated blood.
What is the left atrium?
These vessels contain valves to prevent backflow of blood.
What are veins?
The protein that allows red blood cells to transport oxygen.
What is hemoglobin?
The thin membrane that covers the lungs and lines the thoracic cavity.
What is the pleura?
The liquid component of blood that carries nutrients, hormones, and waste.
What is plasma?
The structure that supports valves and prevent inversion of the valves.
What is papillary muscles?
This layer contains smooth muscle and controls vessel diameter.
What is the tunica media?
The most abundant leukocyte.
What is neutrophil?
What is ciliated pseudostratified columnar epithelium?
The tiny sacs in the lungs where gas exchange occurs.
What are alveoli?
These fibers distribute the impulse throughout the ventricles.
The main force that pulls fluid in to capillaries.
What is oncotic pressure?
The main protein that contributes to osmotic pressure.
The form in which most carbon dioxide is carried in the blood.
What is bicarbonate (HCO₃⁻)?
The blood vessels in the lungs that carry deoxygenated blood from the heart to the alveoli.
What are pulmonary arteries?
The electrical event hidden within this complex is atrial repolarization.
What is the QRS complex?
This enzyme is released by the kidneys in response to low blood pressure.
What is renin?
The cell responsible for the creation of platelets by its own fragmentation.
What is megakaryocytes?
This effect describes how hemoglobin releases more oxygen in tissues where carbon dioxide is high and pH is low.
What is the Bohr effect?
The blood vessels that connect arterioles to venules and are the site of exchange.
What are capillaries?
The phase of the heart cycle where the AV valves are closed and the pressure is increasing.
What is isovolumetric contraction?
Baroreceptors primarily respond to this type of change in blood vessels.
What is stretch or pressure change?
A patient comes into the emergency room after a car accident and needs an immediate blood transfusion. The lab technician must determine the patient’s blood type before giving blood. The technician mixes the patient’s red blood cells with anti-A, anti-B, and anti-D (Rh) sera and observes clumping in the anti-B and anti-D wells. What is her blood type?
B positve
Contraction of this muscle increases thoracic cavity volume, lowers intrapulmonary pressure, and drives air into the lungs during inspiration.
What is the diaphragm?
The disorder characterized by a deficiency of red blood cells or hemoglobin, reducing oxygen-carrying capacity.
What is anemia?
