00:01 Okay, i want to answer these questions, let's label each of these structures here with the function here, okay? so we have here a structure from which the d tendoni originate.

00:15 And this is going to go for papillary muscles.

00:20 You have here age.

00:21 Then we have prevents blood movement from right ventricle to the right atrium.

00:25 If this is your heart, okay, this is the right area.

00:32 This is the right ventricle, this is the left atrium, and this is the left ventricle.

00:37 And what is going to prevent the blood movement from white ventricle to, for the right ventricle, i'm sorry, to the right atrium is the atro -ventricular valve that is found here.

00:49 Okay, specifically the atro ventricular valve that is located at the right side is called tricuspid valve.

00:58 Okay, so the answer here is going to be l.

01:03 Now, question three says membranes around the heart, and this is going to be for pericardial that is here, j.

01:11 This is the pericardial that is going to be so bound in the heart, okay? then you have prevents blood movement from left ventricle to left atrium, it means in this direction, okay? and here you're going to have also atrial intracurial valves that in this case specifically they are called mitral valve.

01:31 Okay, so you have here, f.

01:35 Now question 5 says gives you guys to the left and white pulmonary arteries.

01:40 So remember that from the white ventricle of the heart, you're going to have the pulmonary trunk and this pulmonary trunk is going to divide into the right and the left pulmonary arteries.

01:52 Okay, so you have here pulmonary trunk, there is k, then you have drains blood from myocardium into the white atroof.

02:00 And this is the function of the coronary sinus.

02:03 First of have clear d...
