The aorta is a large blood vessel that branches off from the heart and pumps oxygen-rich blood back into the body. The aorta carries blood away from the left ventricle and circulates it into the systemic circuit. The systemic circuit are the vessels between the aortic semilunar valve and the entrance to the right atrium.Know More
Oxygenated blood enters the body through capillary networks surrounding the alveoli of the lungs. Alveoli, air-filled pockets with barriers thin enough to allow oxygen to pass through, oxygenate the blood depleted of oxygen and absorb carbon dioxide for expulsion through the lungs. An exchange occurs at the alveoli, which transfers fresh oxygen from the lungs to the blood and carbon dioxide from the blood to the alveoli. The function of the aorta is to pump this new oxygen-rich blood from the left ventricle of the heart, where the oxygenated blood is deposited, and circulate it back into the body.
The shape of the aorta assists with blood circulation. It has four main sections: the ascending aorta, the aortic arch, the descending thoracic aorta and the abdominal aorta. The ascending aorta begins at the semilunar valve of the left ventricle and connects to the coronary arteries. The aortic arch curves like a cane and connects the ascending aorta and descending aorta. The descending aorta is a continuation of the aortic arch and is divided into the two sections: the thoracic aorta and the abdominal aorta.Learn more about Human Anatomy
According to HealthCentral, the artery that runs from the heart to supply blood to the rest of the body is the aorta. Many forces in the body cause the aorta to weaken, and as it weakens, it becomes enlarged. Enlarged aortas are fairly common, especially in people who have high blood pressure, are overweight, have abnormal cholesterol or smoke.Full Answer >
External nares, or nostrils, perform the basic function of being the passageway through which oxygen enters the body. Nostrils have many different parts within them that perform their own individual functions.Full Answer >
A rib fracture can affect the heart by damaging the aorta or other major blood vessels, according to Mayo Clinic. Blunt cardiac injury is a common complication from rib fractures, according to The American Association for the Surgery of Trauma.Full Answer >
An organism’s mouth allows it to take resources, such as food and water, into its body. In some organs the mouth serves sensory, manipulative and communication roles as well. For example, humans can detect tastes with their mouth, while animals such as dogs, birds and cats use their mouths to manipulate items. Additionally, many mammals and birds use their mouths to communicate with each other through languages and songs. Some animals use their mouths for part of the respiration process as well.Full Answer >
