The movement of molecules from an area of high concentration to an area of low concentration.

The difference in concentration of a substance between two areas.

The process by which oxygen moves from the alveoli (tiny air sacs in the lungs) into the blood.

Tiny air sacs in the lungs where gas exchange occurs.

Tiny blood vessels that surround the alveoli, facilitating gas exchange.

A protein in red blood cells that binds to oxygen, transporting it throughout the body.

The relationship between the partial pressure of oxygen and the binding of oxygen to hemoglobin.

Oxygen molecules bind to hemoglobin more readily when the partial pressure of carbon dioxide is lower.

The movement of particles from an area of high concentration to an area of low concentration.

To increase the surface area available for gas exchange, allowing for more efficient oxygen absorption and carbon dioxide removal.

Alveoli allow for the exchange of oxygen and carbon dioxide between the lungs and the bloodstream.

Fluid in the lungs reduces the surface area available for gas exchange, making it harder for oxygen to enter the blood and carbon dioxide to be released.

Smoking destroys or paralyzes the cilia, which are tiny hairs in the lungs that help remove dust, bacteria, and mucus. This leads to increased mucus buildup and a higher risk of respiratory issues.

Ozone pollution, which increases during summer heatwaves, can cause inflammation in the airways and increase the risk of asthma symptoms.

Breathing through the nose helps clean, warm, and moisturize the air before it reaches the lungs, protecting them from irritants.

After exhaling, not all of the air is removed from the lungs. Residual volume remains to prevent lung collapse.

The process of bringing air into the lungs. This involves the muscles of the chest expanding the chest cavity, creating lower pressure in the lungs, and causing air to flow in.

The process of releasing air from the lungs. This happens when muscles relax, the chest cavity shrinks, increasing pressure in the lungs, and forcing air out.

Exchange of gases between the alveoli in the lungs and the blood capillaries. Oxygen from the inhaled air moves into the blood, while carbon dioxide from the blood moves into the alveoli to be exhaled.

Exchange of gases between the blood capillaries and the body's cells. Oxygen from the blood is delivered to the cells, and carbon dioxide produced by the cells is transferred back into the blood to be transported to the lungs.

The passageway through which air travels from the outside of the body to the lungs. It includes the nose, pharynx, larynx, trachea, bronchi, and bronchioles.

The structures in the lungs responsible for gas exchange between the air and blood. These include the respiratory bronchioles, alveolar ducts, and alveoli.

The process of breathing, which involves both inhalation and exhalation. It is essential for delivering oxygen to the body and removing carbon dioxide.

The system responsible for breathing and gas exchange in the body. It includes the lungs, airways, and muscles involved in breathing.

The functional unit of the lungs where gas exchange occurs. The respiratory zone includes the respiratory bronchioles, alveolar ducts, and alveoli.

The thin walls of capillaries allow for the rapid exchange of gases, nutrients, and waste products between blood and body cells.

The thin walls of capillaries allow for the rapid exchange of gases, nutrients, and waste products between blood and body cells. This is critical for oxygen delivery to cells and removal of carbon dioxide.

The small diameter of capillaries forces red blood cells to squeeze past, increasing their surface area. This enhances the rate of gas exchange.

IV (intravenous) fluids directly enter the circulatory system through veins, allowing for rapid delivery of essential nutrients, medications, and fluids.

IV fluids are administered when a patient needs immediate replenishment of fluids, electrolytes, or medications; especially when oral intake is insufficient or impossible.

Prolonged sitting during travel can impair venous blood return due to inactivity of the skeletal muscle pump.

Venous blood return relies on the skeletal muscle pump, which contracts muscles and compresses veins, aiding in the return of blood to the heart.

Vasoconstriction narrows blood vessels, increasing blood pressure, while vasodilation widens them to lower blood pressure. These mechanisms regulate blood flow to specific tissues based on need.

Red blood cells are constantly being replaced, not slowly.

Red blood cells are formed in the bone marrow, the soft tissue inside bones. They are not stored in the spleen, but rather broken down there when they get old.

The human heart is actually two pumps working together. The right side pumps deoxygenated blood to the lungs, and the left side pumps oxygenated blood to the rest of the body.

Only veins have valves, which prevent blood from flowing back towards the heart.

Despite its complexity, blood flows in one direction throughout the circulatory system - from the heart, to the body, back to the heart.

Not all creatures have a four-chambered heart. Humans do, but some animals have different numbers of chambers, depending on their needs.

Earthworms have a system of blood vessels, but not a true heart. They might have some pumping action, but it's not a centralized organ like ours.

Red blood cells are biconcave (shaped like a donut) and smaller than capillaries, allowing them to easily squeeze through tiny spaces.

The circulatory system's primary role is to transport essential substances, like oxygen and nutrients, to all cells in the body. It also removes waste products, such as carbon dioxide, from the cells.

The circulatory system delivers oxygen to cells, which is necessary for cellular respiration, the process of converting food into energy for your body.

Carbon dioxide is a waste product of cellular respiration. The circulatory system removes it from cells and transports it to the lungs to be exhaled.

Hormones are chemical messengers produced by endocrine glands. The circulatory system delivers these messages to the appropriate target organs.

The circulatory system transports nutrients from the digestive system to all cells, providing them with the building blocks and energy they need.

The circulatory system helps protect the body from infection by transporting white blood cells (WBCs) to sites of infection. It also helps stop blood loss by transporting platelets to injured areas.

The superior vena cava is a large vein that carries deoxygenated blood from the upper body to the right atrium of the heart.

The pulmonary artery carries deoxygenated blood from the right ventricle of the heart to the lungs, where it will be reoxygenated.

The pulmonary vein carries oxygenated blood from the lungs back to the left atrium of the heart.

The aorta is the largest artery in the body, carrying oxygenated blood from the left ventricle of the heart to the rest of the body.
