CVS Lectures 1 - 3

The pulmonary circuit is in ❌ with the systemic circuit. Organ circulations are ❌ branches of the systemic circuit.

The blood vascular system is ❌ entry, continuous ❌. The lymphatic vascular system is ❌ entry, ❌ system.

To shift the same amount of blood per second, ❌ must have a cross sectional area twice that of ❌.

The heart wall's innermost component is the ❌, which is ❌ epithelium that provides a non-stick surface and which prevents ❌. It also contains loose, irregular fibrous connective tissue, small vessels, and ❌.
The next layer is the ❌, which is cardiac muscle.
The next, more superficial layer is the ❌. It contains adipose, connective tissue, and ❌. Its visceral pericardium loops over to become the ❌ pericardium, with the ❌ in between. This space is filled with pericardial fluid that reduces ❌.
The heart is finally wrapped in ❌ pericardium.

The cardiac circulation is the first organ system to receive blood from the aorta. The coronary arteries are named sensibly as the right coronary artery and the left coronary artery. The anterior interventricular artery branches from the ❌ coronary artery. All three of these vessels join the ❌ artery on the ❌ of the heart.
On the ❌ of the heart also reside the great cardiac vein and the small cardiac vein. The ❌ sinus is the final vein which drains into the ❌ atria directly.
