Biology
1 answer:
Shalnov [3]3 years ago
6 0
The skin contains layers that protect the internal parts of the body. The epidermis is the outer layer of the skin that contains cells called kertinocyte that pact together so that no bacteria can pass through the deeper layer of the skin. Aside from this protective barrier, the skin also has Langerhan cells that are part of the immune system. These cells signal the immune system to release white blood cells to protect invading harmful bacteria and other forms of infection. This is the reason why every time you scratch your skin it turns red and becomes swollen.

Which of the following promotes closure of the minivalves associated with lymph capillaries?
Molodets [167]

Answer:

increasing pressure inside the lymph capillary

Explanation:

Lymph is a fluid like the blood which carry the White blood cells which can fight against the infection. The lymph flows in separate vessels called lymphatic vessels.

The lymphatic vessel is very thin-walled smooth muscle containing tube-like structure which allows the transport of lymph.

The lymph vessel like blood vessel contains the valves called mini valves which prevent the backward flow of the lymph.

When the pressure in the tiny lymph capillaries which supplies lymph to the organs increases, the mini valves closes to prevent backflow of lymph and is the mechanism of lymph flow.

Thus, the selected option is the correct answer.

If a person uses up his or her reserve supply of glycogen and still does not eat, sugar comes from the?
Anvisha [2.4K]

If a person uses up his or her reserve supply of glycogen and still does not eat, sugar comes from the muscle.

Although only liver glycogen directly contributes to the release of glucose into circulation, maintaining a healthy blood glucose concentration is one of the glycogen's key functions. Since skeletal muscles lack glucose 6-phosphatase, they are unable to release glucose, and muscle glycogen primarily serves as a local energy source for activity rather than a source of fuel to keep blood glucose levels stable while fasting.

In fact, the breakdown of muscle glycogen into lactate allows for its delivery to the liver, where it participates in the maintenance of euglycemia through the process of gluconeogenesis (Cori cycle).
