erica [24]

Answer: True

Explanation:

<u>A cell membrane consists of a lipid bilayer made of polar phosphate head and a nonpolar lipid tail.</u> It is semipermeable and regulates the transport of materials through it. For this,<u> it is selectively permeable</u> and since it is made of lipids, hydrophobic and small polar molecules can diffuse easily through it by simple diffusion and down their concentration gradient. However, polar molecules, large molecules (such as glucose) and ions are not able to pass through it because they are repelled.

To accomplish the transport of these molecules that can not diffuse, proteins embebbed in the membrane function as carriers that enable the transport of polar molecules, large molecules and ions by passive (through facilitated diffusion, down its concentration gradient) or active transport (movement against its concentration gradient).

The pulmonary circulation conveys blood that is ______ in oxygen to the lungs before returning back to the ______ side of the he
Oduvanchick [21]

The pulmonary circulation conveys blood that is low in oxygen to the lungs before returning back to the left side of the heart.

<h3>The pulmonary circulation</h3>

The circulatory system is divided into two main parts namely:

  • pulmonary circulation and

  • systemic circulation.

The pulmonary circulation involves the movement of blood between the lungs and the heart.

Blood from the systemic circulation returns to the right side of the heart where it is pumped through the pulmonary artery into the lungs to be oxygenated.

After oxygenation has taken place in the lungs, the blood returns to the left side of the heart through the pulmonary veins.
