How does marijuana get inside you?
It enters through the capillaries of the lungs.
What is the pathway of air once it enters the bronchial tube?
the air enters the bronchioles, and into the aveoli, which are small, one cell-thick sacks of air. These sacks are surrounded by tiny capillaries, which is how your blood retrieves its oxygen. From here, the oxygenated blood is carried back to the heart through the pulmonary vein and pumped into your body.
What allows oxygen in and waste out?
As oxygen enters the body it will travel down the trachea (throat), through the bronchioles (tubes leading to the lungs), and into the lungs. In the lungs there are very tiny grape-like-sacs called alveoli. The membrane on these sacks is very thin, and they are surrounded by many tiny capillaries (blood vessels) whose membrane is also very thin. It is here where oxygen from the alveoli enters the capillaries, and carbon dioxide (waste product) from the capillaries enters the alveoli. The oxygen is now carried through the blood to the heart where it is pumped throughout the body, and the carbon dioxide, now in the alveoli, is expelled as the person exhales. In a situation of altitude it is this process that is hindered. Because of the lower pressure of oxygen the oxygen does not enter the capillaries as easily and the body is deprived of oxygen.
As blood enters a nephron it flows through a network of capillaries known as a?
Glomerulus
The oxygenated blood first enters the?
The oxygenated blood first enters the capillaries, then they carry the blood through other veins to the rest of the body.
How does oxygen get from your lungs and into the blood?
You breathe the oxygen into your lungs. The oxygen then dissolves into the water lining which is called the alveoli. Finally, the oxygen will cling to the red blood cells as they pass through the alveolar capillaries and now the oxygen is in the blood.
What division of the bronchi that enters bronchopulmonary segments?
tertiary bronchioles
Are capillaries part of the lung?
Yes, capillaries form a network around the alveoli. It is through the alveolar walls and into the capillaries that oxygen enters the blood stream. Carbon dioxide leaves the blood by the reverse route.
Trace the flow of blood through the nephron?
the flow of blood through the nephron is : enters through the afferent arteriole, then flows through the glomerulus and into the efferent arteriole. Blood then enters the peritubular capillaries and the vasa recta and then flows through the cortex and medulla of the kidneys close to the tubules Answer: so the flow is afferent arteriole, efferent arteriole, peritubular capillaries, vasa recta
What is Main branch of the respiratory system that enters each of the lungs?
it is bronchioles
What are the parts of a respiratory system top to bottom?
In order (the path of air) ; The nose. The Pharynxa.k.a the throat. the trachea. the bronchi. and the lungs. The respiratory system is rather simple: a breath starts out when a person clenches their diaphragm, creating a vacuum that the air is drawn into. The air enters in the trachea, or windpipe, going through one of the two bronchial tubes, which branch into smaller bronchioles. The bronchioles end in small sacs called alveoli, which have capillaries in them. The carbon dioxide in the blood in the capillaries is then exchanged for the oxygen in the air by diffusion. When that is done, the now oxygenated blood travels all over the body, supplying oxygen where it is needed. Then, the diaphragm relaxes, and the carbon dioxide rushes out of the alveoli, through the bronchioles and the the bronchial tubes, and out of the trachea, and out of the body through the nose or mouth. Then, it is done, and the diaphragm clenches...
What is the pressure when the blood leaves the small arteries and enters the Capillaries?
The blood pressure is usually high when blood leaves the small arteries and enters the capillaries.
