Study Notes

Heart Function and Structure

The left ventricle pumps blood to the rest of the body.
The inferior vena cava is the correct answer, not specified why.
The Purkinje fibers are not part of the intrinsic conduction system of the heart.
Ventricular contraction occurs during systole.

Heart Blood Supply

The coronary artery supplies blood to the myocardium itself.
The coronary sulcus is the term for the grooves on the surface of the heart that contain coronary vessels.
The interventricular septum separates the left and right sides of the heart.

Blood Type Classification

The Rh system determines the presence or absence of Rh antigens in blood type classification.

Blood Vessels

Vasoconstriction is the decrease in the size of the lumen of a blood vessel.
The tunica media is the layer of the blood vessel responsible for vasoconstriction and vasodilation.
The tunica externa is not the outermost layer of a blood vessel; it's the tunica adventitia.
Elastic arteries have a specific function, but it is not specified.

Respiratory System

The nasal cavity is not part of the lower respiratory system.
The right lung has superior lobe, middle lobe, and inferior lobe, with an oblique fissure.
The respiratory membrane serves as a barrier for gas exchange between alveolar air and blood.
Asthma is characterized by smooth muscle spasms in bronchioles causing airway constriction.

Circulatory System

The vestibular fold or false vocal cords have a function, but it is not specified.
Venous valves prevent backflow of blood.
The skeletal pump aids in venous blood flow to the heart.
The thoracoabdominal pump assists in venous blood flow to the heart.
Atherosclerosis is characterized by plaque buildup in the inner lining of arteries.

Lymphatic System

The lymphatic system is responsible for drainage of excess interstitial fluid and immune responses.
The immune response involves invasion, recognition, production and amplified defense, attack and destroy, and slowdown and reserve.
T cells conduct cell-mediated responses.
The thymus is the site where T cells mature.
Lymphocytes are primarily produced in the red bone marrow.
Lymphatic capillaries drain excess interstitial fluid.
Lymph nodes filter lymph along lymphatic vessels.
