The difference is internal respiration happens at the cellular level while external respiration is the actual breaths. 2. What are the key functions overall of the respiratory system? The key functions of the respiratory system is to bring air and blood into the alveolar air sacs so that the air can enter into the bloodstream while the carbon dioxide exits. It also maintains the body’s pH levels and body temperature.
The air which we breathe in which is kept in the lungs, is the transferred into blood. The blood then goes around the heart, which then pumps oxygenated blood from lungs back into the body. The 2 systems also work together in order to get rid of carbon dioxide which is there as a metabolic waste product. D1
Moving air breathed in and out creates sound. Trachea – Filters air we breathe and branches into the Bronchi. Bronchi – Two air tubes that branch off the Trachea and carry air directly into the lungs. Bronchioles – Branches from the Bronchi, which ends, contain the alveoli. Alveoli – Very small air sacs that are the destination of air breathed in.
If you guessed the larynx, you would be correct. Not only is the larynx responsible for producing our voice, it also helps us swallow and breathe (Larynx, n.d.). Passing through the larynx, we enter the pharynx. Pharynx is just the medical term for the throat. Who knew that the pharynx is part of the respiratory and the digestive system?
1. Cardiovascular System is a complex network of the heart, blood vessels and blood. Its job is to deliver nutrients to the human body and remove excretory products from the body parts, it’s also protects the human body against infections, distribution of heat. At the centre of the cardiovascular system is the heart, a four chambered pump that dispenses blood to the arteries. The arteries carry nutrients and oxygenated blood to the body’s tissues.

As the deoxygenated blood continues on its journey through the heart from the right ventricle, it makes its exit by way of the pulmonic valve. This structure is a one-way valve with prevents the flow of blood back into the right ventricle once it leaves the heart. http://www.healthline.com/human-body-maps/pulmonary-valve The mitral valve: This valve is located between the left atrium and the left ventricle. As the now oxygenated blood flows back through the left atrium, it does so under increased pressure.
The right atrium receives deoxygenated blood via the superior and inferior vena cava. The blood then goes through the right ventricle and out to the lungs where it becomes oxygenated. The oxygenated blood then travels to the left atrium via the pulmonary veins, to the left ventricle, and then out to the rest of the body and organs through the aorta. The blood also supplies oxygen and nutrients to the heart via the coronary arteries that branch from the aorta. This pumping action of blood flow is controlled by electrical impulses in the heart.
The breathing tube provides an airway so the ventilator is able to use triggers to control the oxygen input and carbon dioxide output. The ventilator will create a vacuum so your lungs will fill up with air and fall back naturally allowing a patient to stay
The respiratory and circulatory systems work together to deliver oxygen to cells of the body (the lungs through air exchange, and the circulatory system by delivery of hemoglobin containing red cells to the capillaries where oxygen is released into the tissues) and removal of carbon dioxide. The circulatory system delivers nutrients absorbed through the walls of the small intestine to other organs (such as the liver, muscles, brain, heart), and delivers oxygenated blood to the digestive system. You breathe in oxygen into your lungs. The oxygen diffuses across the thin walls of the alveoli in the lungs and the thin walls of the blood vessels in the lungs into the blood stream. Here it attaches to the hemoglobin molecules inside red blood cells.
Plasma carries food from the stomach to cells but carries waste from the cells to the kidneys and intestine. The body needs lots of haemoglobin because it will combine with the gases; oxygen and carbon dioxide. The red cells carry the oxygen in the arteries and capillaries to cells of the body. One function of the blood is to transport materials within plasma and hemoglobin around the body. Plasma contains hormones, nutrients and waste substances.
