which one of these is NOT a function of the heart
securing one- way blood flow
taking in O2
managing blood supply
producing blood pressure
What is a key function of the pericardium
It anchors the heart to nearby structures and prevents overstretching.
It provides insulation to maintain cardiac temperature.
It allows for contraction of the heart.
It helps with electrical impulses to maintain a regular heart rhythm
What is the fibrous pericardium made of and how does this composition allow it to function?
adipose tissue, provides temperature control
muscle tissue, allows it to contract
elastic tissue, allows it to be flexible
connective tissue, makes it tough and stretch-resistant
What is the primary function of the myocardium layer of the heart?
To supply blood to the heart’s chambers
To help blood flow inside the heart
To cause involuntary rhythmic heart contractions
To protect the heart from external shocks
Which condition primarily affects the endocardium layer of the heart, particularly the heart valves
Myocarditis
Myocardial infarction
Heart failure
Endocarditis
