Anatomy of the Respiratory System Nose and Nasal Cavity The nose and nasal cavity form the main external opening for the respiratory system and are the first section of the body’s airway—the respiratory tract through which air moves. The nose is a structure of the face made of cartilage‚ bone‚ muscle‚ and skin that supports and protects the anterior portion of the nasal cavity. The nasal cavity is a hollow space within the nose and skull that is lined with hairs and mucus membrane. The function

Respiration. *The respiratory system consists of tubes that filter incoming air and transport it into the microscopic alveoli where gases are exchanged the entire process of exchanging gases between the atmosphere and body cells is called respiration and consists of the following: ventilation‚ gas exchange between blood and lungs‚ gas transport in the bloodstream‚ gas exchange between the blood and body cells‚ and cellular respiration *The organs of the respiratory tract can be divided into two

Cardiovascular Disease in the African American Community Causes‚ Preventions‚ and Treatments Cardiovascular disease (CVD) refers to the dysfunctional conditions of the heart‚ arteries‚ and veins that supply oxygen to vital life- sustaining areas of the body like the brain‚ the heart itself and other vital organs. Since the term cardiovascular disease refers to any dysfunction of the cardiovascular system there are many different diseases in the cardiovascular category‚ and many of these diseases

Exercise No. Respiratory System I. Introduction Oxygen is a very important element which our body needs. Without oxygen life is not possible without oxygen which helps in producing energies that our body cells need. But‚ how do we acquire this oxygen needed by the body? It is by the process called Respiration. Respiration is a process of taking in and out of air from the body. There are two kinds of respiration called cellular respiration and external respiration. Cellular respiration

The Respiratory System The human respiratory system plays a very important part in our bodies. Without it‚ we wouldn’t be alive! We need air to move through our bodies at all times. Breathing‚ is a key necessity for life. Our respiratory system is made up of many organs that all work together. The goal of breathing is to deliver oxygen to the body and take away carbon dioxide. The respiratory system organs all work together‚ like a engine in a car‚ they all have a important role. Some

Trace the path of a drop of blood from the time it enters the vena cava until it reaches your little finger. Be sure to include the types of blood vessels involved. Deoxygenated blood enters the right atrium from superior and inferior vena cava after having been circulated through the body. ----------------------- From the right atrium‚ blood moves to the right ventricle and is pumped through

CARDIOVASCULAR SYSTEM OF THE HEAD NECK The cardiovascular system consists of the heart‚ blood vessels‚ and the approximately 5 liters of blood that the blood vessels transport. Responsible for transporting oxygen‚ nutrients‚ hormones‚ and cellular waste products throughout the body‚ the cardiovascular system is powered by the body’s hardest-working organ — the heart‚ which is only about the size of a closed fist. Even at rest‚ the average heart easily pumps over 5 liters of blood throughout
