QUIZ

Facilitated Diffusion-Sometimes to get through a membrane, molecules need a little help or facilitation. An example would be the intake of glucose by the body's cells.

Help me across, would ya?

Generally, any cellular transport having to do with water is going to be osmosis. An example is the absorption of water by the small intestines or kidneys.

Get your water runnin'...

Pinocytosis is the process of stationary cells engulfing material to get rid of it. Phagocytosis occurs when cells move around, engulfing particles/bacteria and cell parts, etc.

Survey says, that is a lie!

Active transport requires energy (ATP) to move molecules going against the concentration gradient (going from low to high). The absorption of amino acids or glucose by cells of the small intestines.

Filtration occurs with the use of pressure. An example is blood pressure in our capillaries, forcing plasma out to become tissue fluid.

You need a filter!

Molecules naturally seek to find balance. They can't do yoga, so diffusion occurs with the concentration gradient. An example is the movement of oxygen from the blood to the cells of the body.

Let's diffuse the situation...

Remember, anatomy describes the structure and relationship among parts, while physiology is the study of the function of the body and its parts.

A transverse section means Marty is now cut into top and bottom parts, with a horizontal plane.

Poor Marty..

The respiratory system brings the oxygen in, but the Circulatory system moves the oxygen all over the body within our blood.

I cannot tell a lie...

Marty was divided with a frontal or coronal section.

A split decision?

The ventral cavity contains the Thoracic, abdominal, and pelvic cavities. The dorsal cavity has the cranial and spinal cavities.

All the cavities...almost

Receptor sites on cell membranes are usually made of proteins.

You probably knew, right?

How did you do?
