Which condition affects large arteries and can lead to heart disease?
Anemia
Atherosclerosis
Leukemia
Hypertension
Which arteries help regulate blood flow and pressure to organs?
Capillaries
Elastic arteries
Muscular arteries
Veins
What is the primary role of small arteries?
Exchange gases
Form capillaries
Regulate blood flow to arterioles
Pump blood
Arterioles are primarily responsible for:

Transporting lymph
Which vessels enable exchange between blood and body tissues?
Arteries
Arterioles
Capillaries
Veins
Venules primarily function to:

Transport blood away from the heart
Drain blood from capillaries and allow white blood cell movement
Regulate blood pressure
What is the main function of veins?
Absorb oxygen
Pump blood
Return blood to the heart
Filter toxins
Which vessels absorb interstitial fluid not reabsorbed into blood vessels?
Veins
Capillaries
Lymphatic capillaries
Arteries
What mechanism typically drives fluid into lymphatic vessels?
Gravity

Intercalated discs
Fibrous skeleton of the heart
Endothelium
Which blood vessels are primarily responsible for elastic recoil and pressure regulation?
Capillaries
Elastic arteries
Venules
Lymphatic capillaries
Which part of the heart contains connective tissue, blood vessels, and sometimes adipose tissue?
Endocardium
Myocardium
Epicardium
Pericardium
Muscular arteries maintain blood flow through:
Recoil

Heart contractions
Pulmonary pressure
Which heart layer is composed mostly of connective tissue and fat?
Myocardium
Endocardium
Epicardium
Papillary muscle
