How do pulmonary agents cause pulmonary edema?
Pulmonary agents can cause pulmonary edema by disrupting the normal balance of fluid in the lungs, leading to fluid accumulation in the air sacs (alveoli) and interstitial spaces. This can result from mechanisms such as increased capillary permeability, inflammation, or increased hydrostatic pressure in the pulmonary circulation. Ultimately, this leads to impaired gas exchange and breathing difficulties.
What three structures constitute the respiratory membrane?
The respiratory membrane consists of three main structures: the alveolar epithelium, the capillary endothelium, and the fused basement membranes of both. The alveolar epithelium is a thin layer of cells lining the alveoli, while the capillary endothelium forms the inner lining of the pulmonary capillaries. Together, these structures facilitate efficient gas exchange between the air in the alveoli and the blood in the capillaries.
What is a pulmonary arteriole?
A pulmonary arteriole is a small blood vessel that carries oxygen-poor blood from the right side of the heart to the lungs for oxygenation. These arterioles are part of the pulmonary circulation system that helps exchange carbon dioxide for oxygen in the blood.
What type of blood does a capillary usually carry oxgen rich or poor blood?
The pulmonary artery is the blood vessel that leads away from the heart (Artery=Away), toward the lungs. It is pumping blood to that lungs that just returned from the body (via the vena cava, into the right atrium). So the blood in the pulmonary artery has the lowest concentration of O2 and the highest concentration of CO2. It is just about to pick up lots of oxygen, once it gets to the lungs.
Why is it not necessary for large quantities of blood to enter the pulmonary system of a fetus?
The pulmonary circuit is to exchange respiratory gases between the blood and inhaled air. As a fetus is not yet breathing on its own but receives its oxygen from the mother through the umbilical vein it surpasses the normal function of the pulmonary circuit and is not necessary.
Which transport mechanism causes the respiratory gases to move across the alveolar pulmonary capillary membranes?
Diffusion
What is the mechanism that allows oxygen to move from the alveolar into the pulmonary capillary blood?
Simple diffusion
What 3 types of vessels in lungs?
They are pulmonary artery, pulmonary vein, and capillary.

Ultimately, this leads to impaired gas exchange and breathing difficulties.
Why does oxygen move from the aveloi into the pulmonary capillary blood?
Because of difference in partial pressure
How does ventilation occur?
Pulmonary ventilation occurs as a person inhales and exhales air and air is exchanged between the atmosphere and the alveoli of the lungs. During this, the pulmonary capillary blood gains oxygen and loses carbon dioxide.
What does the alveoi do?
They are especially significant in the gas (air) exchange through to the pulmonary alveolar-capillary membrane.
Trace the path of a red blood cell in a circuit that takes it from the capillary bed of the right kidney to the capillary bed of the left kidney Consider that you are doing this for an animal with a?
capillary bed of the right kidney---venules---veins---right atrium---right ventircle---pulmonary arteries---capillary of the lungs---pulmonary veins---left atrium---left ventricle---aorta---arteries---arterioles---capillary bed of the left kidney (ALMOST positive about the answer, I just had a test on it. Hope it helps!)
What is the function of a pulmonary arteriole?
a pulmonary artieriole is part of the respiratory system. inside the respiratory system is an organ called alveoli and the alveoli are covered in a network of capillary. the job of the pulmonary arteriole is to carry deoxygenated blood into the capillary network.
What three structures constitute the respiratory membrane?
The respiratory membrane consists of three main structures: the alveolar epithelium, the capillary endothelium, and the fused basement membranes of both. The alveolar epithelium is a thin layer of cells lining the alveoli, while the capillary endothelium forms the inner lining of the pulmonary capillaries. Together, these structures facilitate efficient gas exchange between the air in the alveoli and the blood in the capillaries.
What is pulmonary respiration?
The mechanism of pulmonary respiration: It includes breathing movement, exchange of gases, in lungs, transport of gases by blood and exchange of gase by tissue.
