Heart
These are the atrioventricular valves
Tricuspid / Mitral
An RBC has A antigens on the surface of the cell, these antibodies would be found in the bloodstream
Anti-A
This "flap" keeps food and fluid out of the airway
The left side of the head would be drained by this duct
Thoracic duct
The systemic circuit sends blood to the?
Rest of the body
The "heme" portion of this protein is involved in oxygen transport
Hemoglobin
Surfactant is secreted by these cells
Type 2 Alveolar cells
The thoracic duct empties into this vessel that returns deoxygenated blood to the heart.
Left subclavian vein
This chamber of the heart is the most muscular
Left Ventricle
The kidneys secrete this to create more RBCs
Erythropoeitin
The diaphragm is this shape during relaxation
Curve shaped (pushing against the lungs)
Dendritic cell
This is the primary pacemaker of the heart. This is the secondary pacemaker
SA Node (primary)
AV Node (secondary)
These are chemoreceptors that monitor the blood chemistry (pH, CO2, and O2)
Carotic / Aortic Bodies
This can be found in the respiratory zone
Alveoli
Epithelial tissue is part of this side of the immune system
Innate immunity
Follow the path of blood travel from the lungs, to the heart, to the body
Lungs > Pulmonary Veins > L.A > Mitral Valve > L.V > Aortic Valve > Aorta
These are the three vessels found on the aortic arch
"ABCS"
Brachiocephalic artery
Left Common Carotic
Left Subclavian
Explain how the diaphragm causes pressure changes inside the thoracic cavity, and how this causes diffusion
1. The diaphragm is relaxed at rest. During inhalation, it flattens and decreases pressure in the thoracic cavity
2. Air can diffuse from the atm to lungs due to pressure differences
3. Exhalation increases pressure to be higher than atm, forcing air out of lungs via diffusion
List the primary/secondary lymphoid organs. State the difference between primary vs. secondary.
Primary: Bone marrow / thumus. Site of hematopoeisis.
Secondary: lymph nodes, spleen, tonsils. Site of t/b cell activation.
