Cardiovascular System

Vascular Segments

As blood exits the left ventricle, it passes progressively through the aorta, arteries, arterioles, capillaries, venules, veins, and vena cava before returning to the right atrium. These vascular segments have significant functional differences. Arteries And Arterioles An extensive network of arteries and arterioles branch off of the

Pulmonary Circuit

The cardiovascular system is categorized into the pulmonary circuit as well as the systemic circuit. The blood among the heart and the lungs is transported by pulmonary circuit, which is made up of arteries and veins. The circuit starts at the right ventricle and terminates at the

Circulation in Specific Vascular Beds

Blood flow serves multiple functions. Matching of blood flow to metabolic needs is complex in organs that have variable metabolic rates, such as skeletal muscle. Local regulation of blood flow is well developed in tissues that have a low tolerance for ischemia, such as the brain and

The Systemic Circulation

Systemic circulation is the part of the cardiovascular system which: Carries oxygenated blood away from the heart via the aorta from the left ventricle towards the rest of the body. Brings back deoxygenated blood towards the heart. The systemic circuit, which contains about 84 percent of the

Facial Bones – What Bones Form The Face?

The paired bones of the face are the maxillae, palatine bones, zygomatic bones, lacrimal bones, nasal bones, and inferior nasal conchae. The single bones are the vomer and mandible. The maxillae (mak-sil’-e) form the upper jaw. Each maxilla is formed separately, but they are joined at the
