Question 10 1 pts In tissue capillaries: the partial pressure gradients favor diffusion of O, out of interstitial fluids and into blood and CO2 out of interstitial fluid and into blood, the partial pressure gradients favor diffusion of Os out of interstitialfluids and into blood and CO, out of blood and into interstitial fluid, the partial pressure gradients favor diffusion of O, out of blood and into interstitial fluids and CO, out of blood and into interstitial fluid. the partial pressure gradients favor diffusion of Oy out of blood and into interstitialfluids and CO, diffusion out of interstitial fluid and into blood D Question 11 1 pts The neurotransmitter is classified as a biogenic amine. It is generally excitatory and cocaine abuse causes the reduction of its receptor in the brain. nitric oxide substance P O glutamate O dopamine O acetylcholine

Answer 1

10. The partial pressure gradients favour diffusion of O2 out of blood into interstitial fluids and CO2 diffusion out of interstitial fluids and into blood.

11. Dopamine

.

The partial pressure gradient at tissue level is such that it favour the diffusion of oxygen to tissue and favour the diffusion of CO2 into blood to transport into lungs.

Dopamine is an endogenous catecholamine, also known as biogenic amine, and is a excitatory neurotransmitter in certain areas of brain.
