It forms the central structure of the skeleton, with the function of protecting the brain, spinal cord, heart and lungs. The remaining 126 bones make up the appendicular skeleton; they include the arms, legs, shoulder girdle and pelvic girdle.
Which part of skeleton protects heart and lungs?
The ribs are connected to the sternum with a strong, somewhat flexible material called cartilage. The rib cage help protects the organs in the chest, such as the heart and lungs, from damage.
Does the axial skeleton protect the heart and lungs?
Your axial skeleton protects your brain, spinal cord, heart, lungs and other important organs.
What structure protect the lungs?
Your lungs are protected by your rib cage, which is made up of 12 sets of ribs.
What is the heart protected by?
The pericardium is a thin sac that surrounds your heart. It protects and lubricates your heart and keeps it in place within your chest. Problems can occur when the pericardium becomes enflamed or fills with fluid.
What does the appendicular skeleton do?
The appendicular skeleton supports the attachment and functions of the upper and lower limbs of the human body.
What does the appendicular skeleton include?
The appendicular skeleton is comprised of the upper and lower extremities, which include the shoulder girdle and pelvis. The shoulder girdle and pelvis provide connection points between the appendicular skeleton and the axial skeleton to where mechanical loads transfer.
Which membrane covers the lungs and provide protection?
The pleural membranes are two layers of serous membrane which enclose and protect the lung. The superficial layer is called parietal pleura and lines the wall of the thoracic cavity. The deep layer is called visceral pleura and covers the lungs themselves.
How do the heart and lungs work together?
The right side of your heart receives blood from the body and pumps it to the lungs. The lungs fill the blood with oxygen and then send it back to the heart. The left side of the heart receives this oxygen-rich blood from the lungs and pumps it out to the body.
What body structure protects the heart from outside harm?
The rib cage is one of the body’s best defenses against injury from impact. Flexible yet strong, the rib cage protects major vital organs such as the heart, lungs, and liver.
How does the ribs protect the heart and lungs?
The ribs protect the vital organs of the torso, particularly the heart and lungs, by wrapping around from the thoracic vertebrae of the spine in the back to the sternum in the front.

Which organs are not protected by bones in the axial skeleton? Use the image below to help in determining the answer. bladder, uterus, etc. Which would be a part of the appendicular skeleton?
What is the difference between appendicular and axial skeleton?
The appendicular skeleton includes all the bones that form the upper and lower limbs, and the shoulder and pelvic girdles. The axial skeleton includes all the bones along the body’s long axis.
What is the function of axial skeleton?
The axial skeleton consists of the braincase (cranium) and the backbone and ribs, and it serves primarily to protect the central nervous system. The limbs and their girdles constitute the appendicular skeleton.
Which bone is found in the appendicular skeleton quizlet?
The clavicle, shoulder girdle, humerus, pelvic girdle, and femur are part of the appendicular skeleton.
What seals the lungs to the chest wall?
Thin membranes, called pleura, cover the outside of the lungs and the inside of the chest cavity. There’s always a small amount of liquid within this lining to help lubricate the lungs as they expand within the chest during breathing.
What prevents lungs from collapsing?
But two factors prevent the lungs from collapsing: surfactant and the intrapleural pressure. Surfactant is a surface-active lipoprotein complex formed by type II alveolar cells. The proteins and lipids that comprise surfactant have both a hydrophilic region and a hydrophobic region.
What is the name of the serous membrane covering the heart?
The Pericardium. The pericardium is the fibrous sac that surrounds the heart. It can be divided into three layers, the fibrous pericardium, the parietal pericardium, and the visceral pericardium. The parietal and visceral pericardia together form the serous pericardium.
What type of membrane surrounds each of the lungs quizlet?
The pleural membranes completely surround each lung.
Where is your heart and lungs?
The heart and lungs are located in the thorax, or chest cavity. The heart pumps blood from the body to the lungs, where the blood is oxygenated. It then returns the blood to the heart, which pumps the freshly oxygenated blood to the rest of the body.
What is the relationship between the heart and the lungs quizlet?
The heart and lungs work together to get oxygen to the tissues. The heart pumps the blood, and the lungs put oxygen into it. This oxygen-rich blood then circulates throughout the body to nourish the cells; oxygen-depleted blood gets collected from the tissues to be oxygenated in the lungs.
How do you think your heart is protected?
Daily brisk walk for 45 minutes, reducing salt intake, reducing processed food, increasing fruits, nuts, and vegetables in the diet, avoiding overeating, maintaining a normal weight, avoiding mental stress, and regularly taking prescribed medicines are few essential steps to keep blood pressure in control.
Where are the lungs located?
Your lungs are on each side of your heart, inside your chest cavity. They are the main organs of the respiratory system. The right lung is divided into three lobes (sections), and the left lung is divided into two lobes.
Do the ribs cover the heart?
The rib cage surrounds the lungs and the heart, serving as an important means of bony protection for these vital organs.In total, the rib cage consists of the 12 thoracic vertebrae and the 24 ribs, in addition to the sternum.
How many ribs protect lungs?
Most people have 24 ribs, with 12 on each side of the body. The ribs and rib cage are excellent examples of the human body’s multi-faceted and multi-functional design. They are strong enough to support the skeleton and protect the vital organs in the chest cavity, including the heart, lungs, and spleen.
Which of the following is included in the appendicular skeleton quizlet?
The appendicular skeleton is composed of bones that form 1) the upper limbs (arms), 2) the lower limbs (legs), 3) the pectoral or shoulder girdle, and 4) the pelvic or hip girdle.
How many bones are in the appendicular skeleton quizlet?
The appendicular skeleton of 126 bones and the axial skeleton of 80 bones together form the complete skeleton of 206 bones in the human body.
Which organ is protected by the skeletal system?
Protection: It protects our internal organs. The skull protects the brain; the thorax (sternum, ribs and spine) protects the heart, lungs and other viscera (organs within the thorax).
What organs are protected by these bones?
Protects and supports organs: Your skull shields your brain, your ribs protect your heart and lungs, and your backbone protects your spine.
What do the axial and appendicular systems do?
The appendicular skeleton consists of 126 bones and includes all bones of the upper and lower limbs. The axial skeleton supports the head, neck, back, and chest of the body and allows for movements of these body regions.

Which is not a part of the appendicular skeleton quizlet?
The head is NOT a part of the appendicular skeleton. Rather, it is a component of the axial skeleton. The head forms the most superior part of the axial skeleton, with the vertebral column, ribs, and sternum forming the rest of this part of the skeleton.
Which membrane is responsible for protection of heart?
The pericardium acts as mechanical protection for the heart and big vessels, and a lubrication to reduce friction between the heart and the surrounding structures. A very important role in all aspects of pericardial functions is played by mesothelial cells.

What happens if your lung pops?
A punctured lung involves air escaping from the lung into the space between it and the chest wall. The condition can cause the lung to collapse, which makes breathing a problem. For a person to understand how a punctured lung occurs, it helps to learn more about the anatomy of the lung.
What is the anatomy of the lungs?
The lungs are the major organs of the respiratory system, and are divided into sections, or lobes. The right lung has three lobes and is slightly larger than the left lung, which has two lobes. The lungs are separated by the mediastinum. This area contains the heart, trachea, esophagus, and many lymph nodes.
