Health
1 answer:
Pani-rosa [81]4 years ago
5 0

Answer:

Endocardium: is the innermost layer of the heart.

Myocardium: is the muscle layer

Pericardium: is a double-wall sac that cointains the heart.

Explanation:

While the Pericardium protects the heart against infection, provides lubrication and fixes it to the mediastinum, the Myocardium is the middle layer  from the heart and the thickest one. It has specialized muscle fibers that carry electrical impulses to the ventricles. It is the muscle layer comprised of cardiomyocytes. The endocardium is comprised of two layers: the inner one is made of endothelial cells and the second one is a subendocardial connective tissue where branches of the heart's conduction system are inmersed.

Point of Service Plans a type of HMO/PPO hybrid. They encourage plan members to seek but are not required to use a primary care
Lena [83]

Answer:

The missing part of the question is if the statement is true or false.

It is true.

Explanation:

In an HMO (health maintenance organization) plan you select a primary care physician, who is your gatekeeper. This person will take care of your health and give you referrals to see a specialist or to run tests on you. Your referral is to a provider with your HMO network, if you see a doctor outside this network or without a referral, you have to pay all costs by yourself.

PPO (preferred provider organization) is a health care plan where it is not necessary to have a primary care physician, there are different professionals in your network, and you can see them without a referral or a previous appointment with your physician first. As long as you see professionals with your PPO  network, you will pay cheaper fees, but if you choose to see a doctor that is not with your PPO network, you will have to pay more expensive fees.

In conclusion, members of HMO/PPO can use the plan or not, but if they do, they will pay lower fees.
