Which tissues in the heart helps to protect heart?
Pericardium – a thin, outer lining that protects and surrounds your heart. Myocardium – a thick, muscular middle layer that contracts and relaxes to pump blood around of your heart. Endocardium – a thin, inner layer that makes up the lining of the four chambers and the valves in your heart.
The rib cage help protects the organs in the chest, such as the heart and lungs, from damage.
Cardiac muscle tissue works to keep your heart pumping through involuntary movements. This is one feature that differentiates it from skeletal muscle tissue, which you can control. It does this through specialized cells called pacemaker cells. These control the contractions of your heart.
Histologically, the heart is made of three layers of tissue: epicardium, myocardium, and endocardium.
- Epithelial tissue.
- Connective tissue.
- Nervous tissue.
- Muscular tissue.
The ribs form a cage that shelters the heart and lungs, and the pelvis helps protect the bladder, part of the intestines, and in women, the reproductive organs.
Your pericardium is a protective, fluid-filled sac that surrounds your heart and helps it function properly. Your pericardium also covers the roots of your major blood vessels as they extend from your heart. These are known as your “great vessels,” and they include your: Aorta.
The heart is located between the two lungs in the middle of the chest and slightly to the left of the sternum. The rib cage is known for enclosing and protecting the thoracic cavity. In the thoracic cavity, the heart and lungs are present. Hence, the rib cage protects the heart.
Cardiac muscle tissue, or myocardium, is a specialized type of muscle tissue that forms the heart. This muscle tissue, which contracts and releases involuntarily, is responsible for keeping the heart pumping blood around the body.
Introduction. Cardiac muscle (or myocardium) makes up the thick middle layer of the heart. It is one of three types of muscle in the body, along with skeletal and smooth muscle. The myocardium is surrounded by a thin outer layer called the epicardium (AKA visceral pericardium) and an inner endocardium.
Which muscle tissue is the tissue of the heart?
Overview. The 3 types of muscle tissue are cardiac, smooth, and skeletal. Cardiac muscle cells are located in the walls of the heart, appear striped (striated), and are under involuntary control.
(involuntary muscle) is a specialized form of striated tissue found only in the heart. Cardiac muscle is under the control of the autonomic nervous system.
Intercalated discs are found ONLY in Cardiac muscle tissue. Cardiac muscle tissue is found only in walls of the heart.
The heart lies inside a protective sac of fibrous tissue called the pericardium (figure 2). The heart itself has three layers of tissue: the epicardium, the myocardium, and the endocardium. The epicardium is a thin, shiny membrane covering the surface of the heart.
The heart wall is comprised of three layers: the outer epicardium, the middle myocardium, and the inner endocardium.
- Eat healthy.

- Stay at a healthy weight.
- Quit smoking and stay away from secondhand smoke.
- Control your cholesterol and blood pressure.
- Drink alcohol only in moderation.
- Manage stress.
The heart is the core of the body's circulatory system. It supports your life by continuously pumping blood to every organ in your body. If your heart is unable to function properly, your organs will not receive the oxygen and nutrients they need and their function will be greatly affected even resulting in death.
The skull is present in the head and protects the brain. The heart and lungs are protected by the ribcage in the chest cavity.
Just like the bones of the skeletal system provide structure and support to the body as a whole, the connective tissue of the heart provide structure and support to the heart. This connective tissue in the walls of the heart also serves to provide a separation between the atria and ventricles of the heart.
