Essay On Arteries

Arteries, Veins, and Capillaries

The blood is carried out from the heart through the body from a difficult network of blood vessels. Arteries take away the blood from the heart. The major artery is the Aorta which is sub divided into other main arteries, that is responsible for taking blood into brain, the brachial arteries takes blood to the arms, and the thoracic artery takes blood to thorax and then to renal, gastric and hepatic for the kidney, stomach and liver respectively. Thus, the iliac artery is in charge of flowing blood to lower limbs.

Oral cavity: Oral cavity, generally known as the mouth, is the other external component which is respiratory system part. In reality, oral cavity does not make any additional functions as compared to nasal cavity, however it can increase the air inhaled from nose or act as alternative while inhaling from nasal cavity is quite complex or not possible.

Pharynx: The pharynx is another respiratory tract component, although majority of individual links it with the throat. It looks like a funnel developed from muscles which mainly act as intermediary among larynx, oesophagus and nasal cavity. It is mainly separated into three diverse sections including laryngopharynx, nasopharynx and oropharynx.

Larynx: Larynx is another component; however it represents only smaller respiratory tract section which links the laryngopharynx with trachea. It is generally denoted with the voice box, and it is located at anterior neck section, below hyoid
