|
||||
| show | Aortic valve.
🗑
|
||||

|
||||
| How much oxygen does the heart use? | show 🗑
|
||||
| Where do the coronary arteries arise from? | show 🗑
|
||||
| show | Left main coronary artery (left anterior descending artery and cirumflex artery) and the right coronary artery.
🗑
|
||||
| What is the function of the left main coronary artery? | show 🗑
|
||||
| show | Left anterior descending artery.
🗑
|
||||
| show | Cirumflex artery.
🗑
|
||||
| show | To supply blood to the right side of the heart. The coronary arteries are perfused (passage of fluid) during diastole (period between contractions).
🗑
|
||||
| Specialized muscle tissue composing the wall of the heart. | show 🗑
|
||||
| show | In an interconnected manner (syncytium) so that they can contract and relax in a coordinated manner.
🗑
|
||||
| What are the 3 cardiac muscles? | show 🗑
|
||||
| show | Myocardium.
🗑
|
||||
| The inner lining of the myocardium which is in contact with the blood. | show 🗑
|
||||
| show | Epicardium.
🗑
|
||||
| show | Generate and coordinate the transmission of electrical impulses to the myocardial cells.
🗑
|
||||
| show | Sequential atrioventricular contraction, which provides for the most effective flow of blood, thereby optimiizing cardiac output.
🗑

||||
| Name the components of the conduction system. | show 🗑
|
||||
| show | SA node.
🗑
|
||||
| What is the function of the SA node? | show 🗑
|
||||
| How many pulses does the SA node initiate in a resting normal heart. | show 🗑
|
||||
| show | It is conducted along the myocardial cells of the atrium to the AV node.
🗑
|
||||
| Located in the right atrial wall near the trisucpid valve, but this group of specialized cells have an intrinsic rate of 40-60 impulses per minute. | show 🗑
|
||||
| show | Coordinates the incoming electrical impulses from the atria and, after a slight delay, relays an impulse to the ventricles.
🗑
|
||||
| show | Through a bundle of specialized muscle fibers (bundle of HIS) that travel in the septum separating the left and right ventricles.
🗑
|
||||
| show | Divides into the right and left bundle branches, which terminate in fibers called the Purkinje fibers.
🗑
|
||||
| Where does the right bundle of the Purkinje fibers lead? | show 🗑
|
||||
| show | It divides again into the left anterior and left posterior bundle branches, which fan out into the left ventricular muscle.

|
||||
| show | Tunica adventitia.
🗑
|
||||
| Example of the structure of blood vessels. | show 🗑
|
||||
| show | Arteries further away from the heart contain a greater proportion of smooth muscle fibers bc arteries must be able to constrict and dilate to control BP and volume w/in capillary beds.
🗑
|
||||

|
||||
| Where do oxygen, nutrients, and other substances needed for cellular metabolism travel? | show 🗑
|
||||
| show | Smallest veins; receive capillary blood.
