All vessels leaving the heart are arteries, the largest being the Aorta and leaving the left heart ventricle carrying blood rich in oxygen and poor in carbon dioxide (this one carries the blood from the heart, and branches off to supply blood to your head and neck, your arms, then your abdomen, and then your legs), and there are also 2 pulmonary arteries that carry the blood to the lungs, and leaving from the right ventricle: this blood is poor in oxygen, but rich in carbon dioxide. The vessels bring the blood to the heart are all veins: 2 vena cava (the superior one brings the blood from your arms and head&neck, and the inferior one brings blood form your abdomen and legs) bring oxygen poor in oxygen and rich in carbon dioxide to the heard, whereas 4 pulmonary veins bring blood rich in oxygen to your heart from your lungs, and this blood is poor in carbon dioxide. In summary: your heart pumps from the left ventricle blood rich oxygen to your entire body through arteries. The oxygen is used up, and the blood returns through veins back to the heart, carrying carbon dioxide. The blood arrives at the right atrium of the heard, and then is pumped by the right ventricle to the lungs where the air that you breath in enriches the blood with oxygen, and the air that you breath out gets rid of the carbon dioxide. The oxygen rich blood then returns to hearth through the pulmonary veins, before going through the left atrium and then the left ventricle where the cycle starts again. Arteries: Carry blood FROM the heart Veins: Carry blood TO the heart
The arteries pump blood away from the heart with oxygenated blood down to your feet and ams and veins pump deoxygenated blood to the heart then the lungs transfer some of the oxygen to the deoxygenated blood and the capillaries transfer the blood to and from the arteries to the viens
when you inhale air flows through the trachea to the bronchi to the bronchial to the aviolus witch is were the air is exchanged into the blood
The portions of the lung where this occurs are the alveoli; the portion of the process that occurs in blood vessels takes place in capillaries.
Gas exchange happens in the bed of CAPILLARIES in the lungs.
capillaries in the alveolar tissue of the lungs
The capillaries round the alveoli.
Capillaries
lungs and mouth
Oxygen, carbon dioxide, and water are the substances exchanged between the alveoli (air sacs) and the capillaries in the lungs.
There are two main gasses that are exchanged in the lungs: carbon dioxide and oxygen. The lungs use tiny air chambers called alveoli to take in oxygen and let out carbon dioxide.
The pulmonary artery, because it's the only vessel that oxygenates blood to the lungs.
Oxygen is picked up by the blood when it is at the lungs.
The pulmonary artery carries blood from the heart to the lungs
