- anterior interventricular artery
- pectin =
- Right atrium
- What kind of tissue is endomysium, perimysium and epimysium and where is it located in the myocardium?
- Right ventricle
- a comb
1 of 4 chambers; smooth, thin, posterior wall; thin, rough anterior wall; receives superior and inferior venae cavae and coronary sinus
- c also known clinically as the left anterior descending artery: follows the anterior interventricular sulcus and supplies blood to the interventricular septum and anterior walls of both ventricles;
- d endo = individual cell connective tissue
peri = larger groups of connective tissue surrounding cells.
Starts at the smallest (one cell) being surrounded by endomysium, then groups of cells surrounded by perimysium, then the epimysium and so on.
- e pumps blood into the pulmonary truck, which routes the blood to the lungs where gas exchange occurs.
5 Multiple Choice Questions
- the internal partition that divides the heart longitudinally at the ventricles.
- The endocardium underlies the much more voluminous myocardium, the muscular tissue responsible for the contraction of the heart.
Cardiac muscle is a type of involuntary striated muscle found in the walls and histologic foundation of the heart, specifically the myocardium.
Passes between pulmonary trunk and right auricle; lies in the coronary sulcus; distributes blood to the right atrium, right ventricle and left ventricle.
Surface groove surrounding heart; marks junction between atria and ventricles
5 True/False Questions
Right ventricle →
1 of 4 chambers; rough, muscular walls; muscle wall thicker than either atrium and thinner than left ventricle; Responsible for pumping oxygen poor blood to lungs.
Superior vena cava →
Drainage: Head, Upper limbs, etc.
2 layers of te pericardium → parietal: lines the internal surface of the fibrous pericardium. attaches to the large arteries exiting the heart then turns inferiorly and continues over the external heart surface as the visceral layer.
pulmonary circuit pump → left side of the heart. takes a long pathway through the entire body and encounters about five times as much friction or resistance to blood flow than the pulmonary circuit pump.
peri = → around
