How does alcohol move through the body?
Alcohol primarily travels in the bloodstream.
What contains hormones in a colloid?
The thyroid gland contains hormones in a colloid. Thyroxine and triiodothyronine are stored in the colloid in the thyroid follicles before being released into the bloodstream.
When oxygen move from the lungs to the bloodstream is it by osmosis?
No, the movement of oxygen from the lungs to the bloodstream is not by osmosis. Instead, it occurs through a process called diffusion, where oxygen molecules move from an area of high concentration (in the lungs) to an area of lower concentration (in the bloodstream) to reach equilibrium.
How can a torch be used to test a colloid?
A torch can be used to test a colloid by shining the light through the colloid. If the colloid scatters the light making it visible (Tyndall effect), then it is a colloid. This is because the particles in the colloid are large enough to scatter light, unlike particles in a solution which are too small.
Can light shine through a colloid?
Yes, light can shine through a colloid because the particles in a colloid are small enough to allow light to pass through without scattering it. This is why colloids appear transparent or translucent.
What happens when you shine a light through a colloid?
When light is shone through a colloid, the individual particles in the colloid scatter the light due to their small size and random distribution. This scattering causes the light to become visible as a beam or cone of light passing through the colloid. This effect is known as the Tyndall effect.
Is light able to pass through a colloid?
No
How is glucose absorbed into the bloodstream?
Glucose is absorbed into the bloodstream through a process called facilitated diffusion in the small intestine. Specialized proteins called glucose transporters help move glucose molecules from the intestine into the bloodstream, where it can be used for energy by the body's cells.
Which nutrients move into the bloodstream?
absorption
How are hormones distributed through the body?
Hormones are distributed through the body by being secreted into the bloodstream by endocrine glands, which then carry them to target tissues and organs where they exert their effects. These hormones act as chemical messengers that regulate various physiological processes and help maintain homeostasis in the body.
How do particles move around the body?
Particles move around the body through the bloodstream, lymphatic system, or cell-to-cell transport depending on their size, charge, and composition. In the bloodstream, particles are carried by the circulation, while in the lymphatic system, they are transported through lymph vessels. On a cellular level, particles can be taken up by cells through processes like endocytosis or diffusion.
How do gases pass through the aveoli?
Gases pass through alveoli via the process of diffusion. Oxygen molecules move from the alveoli into the bloodstream, while carbon dioxide molecules move from the bloodstream into the alveoli to be exhaled. This gas exchange occurs due to the difference in concentration gradients of oxygen and carbon dioxide between the alveoli and the capillaries.
