Cardiovascular
The vessel that returns deoxygenated blood to the heart
What is the Vena cava (superior and inferior)
The large leukocytes that roam the body looking for invaders or damaged cells and if they encounter one, they swallow and digest the pathogen
Macrophage
What is the name for the following definition: "the main passage for air at the front of the neck. It has rings of cartilage to keep it open. Sometimes called the windpipe"
the trachea
This muscle is branched with visible nuclei and helps keep the heart beating
Cardiac Muscle
The imaging tool that can be used to find blood clots
an angiogram
How does vaccines impact the immune response
Faster immune response with more antibodies
as volume increases, pressure...
decreases
A latent period on a myogram shows...
time between muscle contractions
The heart rate is ____ when the peaks/waves on an EKG are close together
fast
If a person is type AB, Rh-, and has been exposed to Rh+ blood in the past, what antibodies do they have in their system?
Rh antibodies
Gases move from high concentration to low concentration, but also…
from areas of high partial pressure to low partial pressure
Where is the Z line, and what happens to it during muscle contraction?
Z-line at each end of the sarcomere.
When muscles contract, Z lines get closer as the sarcomere that shortens
2 factors that help blood in the veins get to the heart
skeletal muscles and one-way valves
A hematocrit sample has a thicker than normal buffy layer. What does this tell you about the person the sample this came from?
Sick with an infection or possibly leukemia (abnormal WBC numbers)
the dominant/primary pathway for breathing regulation detects ______ concentration by sensors in the _____
CO2, medulla oblongata/brain stem
Why is Ca2+ needed for muscle contraction?
Activates troponin, which moves tropomyosin out of the way
Place the following in order, following blood flow, starting from the vena cava: (1)Vena cava, (2) aorta, (3) left atrium, (4) right ventricle, (5) right atrium, (6) pulmonary artery, (7) pulmonary vein, (8) left ventricle
(1) vena cava, (5) right atrium, (4) right ventricle, (6) pulmonary artery, (7), pulmonary vein, (3) left atrium, (8), left ventricle, (2) aorta
Place the following events in the correct order:
(1) Clotting factors released from injury site, (2) Fibrinogen converted to fibrin, (3) Thrombin activated, (4) Thrombocytes stick to tissue and amplify signals — put them in the correct order of occurrence in the cascade.
1 (clotting factors released) → 4 (thrombocytes adhere and amplify) → 3 (thrombin activated) → 2 (fibrinogen converted to fibrin)
Place the following events of inhalation in order:
(1) diaphragm and intercostal muscles contract, (2), volume of chest cavity increases and pressure decreases,(3) air rushes into the lungs, (4), pressure in the chest is now negative relative to the outside
(1) the diaphragm and intercostal muscles contract, (2) volume of chest cavity increases and pressure decreases, (4) pressure in chest is now negative relative to the outside, (3) air rushes into the lungs
Place the following in the correct order:
(1) Myosin grabs actin and pulls Z lines in, (2) ATP is used so myosin can let go and grab another actin, (3)Nerve impulses arrive at the sarcomere, (4) Steps repeat as needed to strengthen contraction,(5) Ca2+ arrives and opens up binding sites on actin
